How Can I Get User-Selected Text from a Website Using JavaScript?

Get the Highlighted/Selected Text

Is it possible to obtain text highlighted or selected by a user within a website using jQuery?

Answer:

Getting the user-selected text is straightforward. Using jQuery offers no advantages because it can be accomplished using the window and document objects.

function getSelectionText() {
    let text = "";

    if (window.getSelection) {
        text = window.getSelection().toString();
    } else if (document.selection &amp;&amp; document.selection.type != "Control") {
        text = document.selection.createRange().text;
    }

    return text;
}

Alternatively, if you wish to consider selections in and textual <input> elements, consider using the following:</p> <pre class="brush:php;toolbar:false">function getSelectionText() { let text = ""; const activeEl = document.activeElement; const activeElTagName = activeEl ? activeEl.tagName.toLowerCase() : null; if ( (activeElTagName == "textarea") || (activeElTagName == "input" && /^(?:text|search|password|tel|url)$/i.test(activeEl.type)) && (typeof activeEl.selectionStart == "number") ) { text = activeEl.value.slice(activeEl.selectionStart, activeEl.selectionEnd); } else if (window.getSelection) { text = window.getSelection().toString(); } return text; } document.onmouseup = document.onkeyup = document.onselectionchange = function() { document.getElementById("sel").value = getSelectionText(); };</pre><p>The above is the detailed content of How Can I Get User-Selected Text from a Website Using JavaScript?.

The engine traverses and marks the active object from the root object, and unmarked is treated as garbage and cleared. For example, when the object is no longer referenced (such as setting the variable to null), it will be released in the next round of recycling. Common causes of memory leaks include: ① Uncleared timers or event listeners; ② References to external variables in closures; ③ Global variables continue to hold a large amount of data. The V8 engine optimizes recycling efficiency through strategies such as generational recycling, incremental marking, parallel/concurrent recycling, and reduces the main thread blocking time. During development, unnecessary global references should be avoided and object associations should be promptly decorated to improve performance and stability.</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796836217.html" title="How to make an HTTP request in Node.js?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/431/639/175234432058757.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="How to make an HTTP request in Node.js?" /> </a> <a href="http://ipnx.cn/faq/1796836217.html" title="How to make an HTTP request in Node.js?" class="phphistorical_Version2_mids_title">How to make an HTTP request in Node.js?</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 13, 2025 am 02:18 AM</span> <p class="Articlelist_txts_p">There are three common ways to initiate HTTP requests in Node.js: use built-in modules, axios, and node-fetch. 1. Use the built-in http/https module without dependencies, which is suitable for basic scenarios, but requires manual processing of data stitching and error monitoring, such as using https.get() to obtain data or send POST requests through .write(); 2.axios is a third-party library based on Promise. It has concise syntax and powerful functions, supports async/await, automatic JSON conversion, interceptor, etc. It is recommended to simplify asynchronous request operations; 3.node-fetch provides a style similar to browser fetch, based on Promise and simple syntax</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796836292.html" title="JavaScript Data Types: Primitive vs Reference" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/431/639/175234579081669.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="JavaScript Data Types: Primitive vs Reference" /> </a> <a href="http://ipnx.cn/faq/1796836292.html" title="JavaScript Data Types: Primitive vs Reference" class="phphistorical_Version2_mids_title">JavaScript Data Types: Primitive vs Reference</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 13, 2025 am 02:43 AM</span> <p class="Articlelist_txts_p">JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796832745.html" title="JavaScript time object, someone builds an eactexe, faster website on Google Chrome, etc." class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/246/273/173914572643912.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="JavaScript time object, someone builds an eactexe, faster website on Google Chrome, etc." /> </a> <a href="http://ipnx.cn/faq/1796832745.html" title="JavaScript time object, someone builds an eactexe, faster website on Google Chrome, etc." class="phphistorical_Version2_mids_title">JavaScript time object, someone builds an eactexe, faster website on Google Chrome, etc.</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 08, 2025 pm 02:27 PM</span> <p class="Articlelist_txts_p">Hello, JavaScript developers! Welcome to this week's JavaScript news! This week we will focus on: Oracle's trademark dispute with Deno, new JavaScript time objects are supported by browsers, Google Chrome updates, and some powerful developer tools. Let's get started! Oracle's trademark dispute with Deno Oracle's attempt to register a "JavaScript" trademark has caused controversy. Ryan Dahl, the creator of Node.js and Deno, has filed a petition to cancel the trademark, and he believes that JavaScript is an open standard and should not be used by Oracle</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796830657.html" title="React vs Angular vs Vue: which js framework is best?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/431/639/175165349052637.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="React vs Angular vs Vue: which js framework is best?" /> </a> <a href="http://ipnx.cn/faq/1796830657.html" title="React vs Angular vs Vue: which js framework is best?" class="phphistorical_Version2_mids_title">React vs Angular vs Vue: which js framework is best?</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 05, 2025 am 02:24 AM</span> <p class="Articlelist_txts_p">Which JavaScript framework is the best choice? The answer is to choose the most suitable one according to your needs. 1.React is flexible and free, suitable for medium and large projects that require high customization and team architecture capabilities; 2. Angular provides complete solutions, suitable for enterprise-level applications and long-term maintenance; 3. Vue is easy to use, suitable for small and medium-sized projects or rapid development. In addition, whether there is an existing technology stack, team size, project life cycle and whether SSR is needed are also important factors in choosing a framework. In short, there is no absolutely the best framework, the best choice is the one that suits your needs.</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796829862.html" title="Understanding Immediately Invoked Function Expressions (IIFE) in JavaScript" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/253/068/175156814092778.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="Understanding Immediately Invoked Function Expressions (IIFE) in JavaScript" /> </a> <a href="http://ipnx.cn/faq/1796829862.html" title="Understanding Immediately Invoked Function Expressions (IIFE) in JavaScript" class="phphistorical_Version2_mids_title">Understanding Immediately Invoked Function Expressions (IIFE) in JavaScript</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 04, 2025 am 02:42 AM</span> <p class="Articlelist_txts_p">IIFE (ImmediatelyInvokedFunctionExpression) is a function expression executed immediately after definition, used to isolate variables and avoid contaminating global scope. It is called by wrapping the function in parentheses to make it an expression and a pair of brackets immediately followed by it, such as (function(){/code/})();. Its core uses include: 1. Avoid variable conflicts and prevent duplication of naming between multiple scripts; 2. Create a private scope to make the internal variables invisible; 3. Modular code to facilitate initialization without exposing too many variables. Common writing methods include versions passed with parameters and versions of ES6 arrow function, but note that expressions and ties must be used.</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796832608.html" title="Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/253/068/175191360175213.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript" /> </a> <a href="http://ipnx.cn/faq/1796832608.html" title="Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript" class="phphistorical_Version2_mids_title">Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 08, 2025 am 02:40 AM</span> <p class="Articlelist_txts_p">Promise is the core mechanism for handling asynchronous operations in JavaScript. Understanding chain calls, error handling and combiners is the key to mastering their applications. 1. The chain call returns a new Promise through .then() to realize asynchronous process concatenation. Each .then() receives the previous result and can return a value or a Promise; 2. Error handling should use .catch() to catch exceptions to avoid silent failures, and can return the default value in catch to continue the process; 3. Combinators such as Promise.all() (successfully successful only after all success), Promise.race() (the first completion is returned) and Promise.allSettled() (waiting for all completions)</p> </div> <div id="wjcelcm34c" class="phphistorical_Version2_mids"> <a href="http://ipnx.cn/faq/1796832618.html" title="What is the cache API and how is it used with Service Workers?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/253/068/175191380054750.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="What is the cache API and how is it used with Service Workers?" /> </a> <a href="http://ipnx.cn/faq/1796832618.html" title="What is the cache API and how is it used with Service Workers?" class="phphistorical_Version2_mids_title">What is the cache API and how is it used with Service Workers?</a> <span id="wjcelcm34c" class="Articlelist_txts_time">Jul 08, 2025 am 02:43 AM</span> <p class="Articlelist_txts_p">CacheAPI is a tool provided by the browser to cache network requests, which is often used in conjunction with ServiceWorker to improve website performance and offline experience. 1. It allows developers to manually store resources such as scripts, style sheets, pictures, etc.; 2. It can match cache responses according to requests; 3. It supports deleting specific caches or clearing the entire cache; 4. It can implement cache priority or network priority strategies through ServiceWorker listening to fetch events; 5. It is often used for offline support, speed up repeated access speed, preloading key resources and background update content; 6. When using it, you need to pay attention to cache version control, storage restrictions and the difference from HTTP caching mechanism.</p> </div> </div> <a href="http://ipnx.cn/web-designer.html" class="phpgenera_Details_mainL4_botton"> <span>See all articles</span> <img src="/static/imghw/down_right.png" alt="" /> </a> </div> </div> </div> </main> <footer> <div id="wjcelcm34c" class="footer"> <div id="wjcelcm34c" class="footertop"> <img src="/static/imghw/logo.png" alt=""> <p>Public welfare online PHP training，Help PHP learners grow quickly！</p> </div> <div id="wjcelcm34c" class="footermid"> <a href="http://ipnx.cn/about/us.html">About us</a> <a href="http://ipnx.cn/about/disclaimer.html">Disclaimer</a> <a href="http://ipnx.cn/update/article_0_1.html">Sitemap</a> </div> <div id="wjcelcm34c" class="footerbottom"> <p> ? php.cn All rights reserved </p> </div> </div> </footer> <input type="hidden" id="verifycode" value="/captcha.html"> <link rel='stylesheet' id='_main-css' href='/static/css/viewer.min.css?2' type='text/css' media='all' /> <footer> <div class="friendship-link"> <p>感谢您访问我们的网站，您可能还对以下资源感兴趣：</p> <a href="http://ipnx.cn/" title="亚洲国产日韩欧美一区二区三区">亚洲国产日韩欧美一区二区三区</a> <div class="friend-links"> </div> </div> </footer> <script> (function(){ var bp = document.createElement('script'); var curProtocol = window.location.protocol.split(':')[0]; if (curProtocol === 'https') { bp.src = 'https://zz.bdstatic.com/linksubmit/push.js'; } else { bp.src = 'http://push.zhanzhang.baidu.com/push.js'; } var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(bp, s); })(); </script> </body><div id="tr9ic" class="pl_css_ganrao" style="display: none;"><sub id="tr9ic"><center id="tr9ic"><pre id="tr9ic"><tt id="tr9ic"></tt></pre></center></sub><thead id="tr9ic"><samp id="tr9ic"><delect id="tr9ic"><ul id="tr9ic"></ul></delect></samp></thead><delect id="tr9ic"><tt id="tr9ic"></tt></delect><center id="tr9ic"></center><abbr id="tr9ic"></abbr><ul id="tr9ic"><kbd id="tr9ic"><optgroup id="tr9ic"><sup id="tr9ic"></sup></optgroup></kbd></ul><legend id="tr9ic"></legend><address id="tr9ic"></address><output id="tr9ic"><track id="tr9ic"><menu id="tr9ic"></menu></track></output><listing id="tr9ic"></listing><th id="tr9ic"></th><sub id="tr9ic"><acronym id="tr9ic"><video id="tr9ic"><small id="tr9ic"></small></video></acronym></sub><strike id="tr9ic"><center id="tr9ic"><font id="tr9ic"></font></center></strike><var id="tr9ic"><strike id="tr9ic"><dd id="tr9ic"><pre id="tr9ic"></pre></dd></strike></var><del id="tr9ic"></del><i id="tr9ic"></i><small id="tr9ic"></small><strike id="tr9ic"></strike><nobr id="tr9ic"><strong id="tr9ic"></strong></nobr><listing id="tr9ic"><nav id="tr9ic"><menu id="tr9ic"><label id="tr9ic"></label></menu></nav></listing><abbr id="tr9ic"></abbr><nav id="tr9ic"><ol id="tr9ic"><dl id="tr9ic"><form id="tr9ic"></form></dl></ol></nav><li id="tr9ic"></li><font id="tr9ic"></font><th id="tr9ic"><bdo id="tr9ic"></bdo></th><listing id="tr9ic"></listing><menu id="tr9ic"></menu><dd id="tr9ic"></dd><samp id="tr9ic"></samp><legend id="tr9ic"><meter id="tr9ic"><tt id="tr9ic"></tt></meter></legend><blockquote id="tr9ic"><menuitem id="tr9ic"><ins id="tr9ic"></ins></menuitem></blockquote><input id="tr9ic"></input><option id="tr9ic"><tbody id="tr9ic"><dfn id="tr9ic"></dfn></tbody></option><nav id="tr9ic"></nav><wbr id="tr9ic"></wbr><table id="tr9ic"></table><center id="tr9ic"><rp id="tr9ic"></rp></center><sup id="tr9ic"><dl id="tr9ic"><xmp id="tr9ic"><blockquote id="tr9ic"></blockquote></xmp></dl></sup><em id="tr9ic"></em><wbr id="tr9ic"></wbr><cite id="tr9ic"><strike id="tr9ic"></strike></cite><samp id="tr9ic"><delect id="tr9ic"><small id="tr9ic"><abbr id="tr9ic"></abbr></small></delect></samp><strong id="tr9ic"><dl id="tr9ic"><strike id="tr9ic"></strike></dl></strong><acronym id="tr9ic"></acronym><var id="tr9ic"></var><mark id="tr9ic"><ins id="tr9ic"></ins></mark><sup id="tr9ic"></sup><thead id="tr9ic"></thead><strike id="tr9ic"><dfn id="tr9ic"><delect id="tr9ic"></delect></dfn></strike><tr id="tr9ic"><sub id="tr9ic"><tfoot id="tr9ic"></tfoot></sub></tr></div> </html>
