AngularJS: API: ng/directive/ngShow

ngShow

  1. - directive in module ng

ngShow指令根據(jù)ngShow屬性上表達(dá)式來(lái)顯示或隱藏給定的HTML元素。元素的顯示或隱藏是通過刪除或添加ng-hide?CSS 類到元素上來(lái)實(shí)現(xiàn)的。.ng-hide?CSS 類是在AngularJS預(yù)定義的，并且設(shè)置顯示樣式為空(使用!important標(biāo)記)。 對(duì)于CSP 模式請(qǐng)?zhí)砑?angular-csp.css?到你的html文件(參見ngCsp)。

<!-- when $scope.myValue is truthy (element is visible) -->
<div ng-show="myValue"></div>

<!-- when $scope.myValue is falsy (element is hidden) -->
<div ng-show="myValue" class="ng-hide"></div>

當(dāng)ngShow表達(dá)式計(jì)算結(jié)果為假時(shí)，ng-hide CSS 類會(huì)被加到元素的class屬性中，從而讓它變?yōu)殡[藏。當(dāng)為真時(shí)，ng-hide CSS 類會(huì)從元素移除，這樣元素就不會(huì)被隱藏。

為什么使用!important?

你可能想知道為什么要在ng-hide CSS類上使用!important。這是因?yàn)?.ng-hide選擇器很容易被級(jí)別更高的選擇器覆蓋。例如，一些簡(jiǎn)單的改變HTML列表?xiàng)l目的顯示樣式會(huì)讓隱藏的元素顯示。這成為了處理CSS框架時(shí)最大的問題。

通過使用!important，顯示和隱藏行為會(huì)按預(yù)期工作，而不管CSS選擇器間的任何沖突(當(dāng)!important沒用在任何相矛盾的樣式上時(shí))。如果開發(fā)者決定覆蓋樣式來(lái)改變?nèi)绾坞[藏元素，那只需要在自己的CSS代碼中配合使!important即可。

覆蓋 .ng-hide

默認(rèn)情況下，.ng-hide類使用 display:none!important格式化元素。如果你希望改變ngShow/ngHide的隱藏行為，可通過在CSS中重新定義 .ng-hide類來(lái)實(shí)現(xiàn)：

.ng-hide {
  /* this is just another form of hiding an element */
  display:block!important;
  position:absolute;
  top:-9999px;
  left:-9999px;}

默認(rèn)情況下你不需要覆蓋CSS中任何東西，動(dòng)畫就會(huì)針對(duì)顯示樣式生效。

ngShow動(dòng)畫的一些注意點(diǎn)

ngShow/ngHide中動(dòng)畫的顯示和隱藏事件會(huì)在指令表達(dá)式為真或假時(shí)觸發(fā)。 這個(gè)系統(tǒng)工作方式像ngClass的動(dòng)畫系統(tǒng)，除了你必須也包含!important標(biāo)記到覆蓋的顯示屬性中，這樣就可以在元素隱藏動(dòng)畫期間正確執(zhí)行。 

////a working example can be found at the bottom of this page
//.my-element.ng-hide-add, .my-element.ng-hide-remove {
  /* this is required as of 1.3x to properly
     apply all styling in a show/hide animation */
  transition:0s linear all;}

.my-element.ng-hide-add-active,.my-element.ng-hide-remove-active {
  /* the transition is defined in the active class */
  transition:1s linear all;}

.my-element.ng-hide-add { ... }.my-element.ng-hide-add.ng-hide-add-active { ... }.my-element.ng-hide-remove { ... }.my-element.ng-hide-remove.ng-hide-remove-active { ... }

記住，AngularJS的1.3.0-beta.11版本里， 不需要通過阻塞動(dòng)畫過程來(lái)改變顯示屬性，ngAnimate會(huì)為你自動(dòng)處理樣式的切換。

指令信息

  • 這個(gè)指令執(zhí)行優(yōu)先級(jí)為0.

用法

  • 作為屬性使用: 
    <ANY
  ng-show="">
...
</ANY>

動(dòng)畫

addClass: .ng-hide - 在ngShow表達(dá)式計(jì)算結(jié)果為非真時(shí)生效，并且是在內(nèi)容被顯示前。

removeClass: .ng-hide - 在ngShow表達(dá)式計(jì)算結(jié)果為真時(shí)生效，并且是在內(nèi)容被隱藏前。

index.html
Click me: <input type="checkbox" ng-model="checked"><br/><div>
  Show:
  <div class="check-element animate-show" ng-show="checked">
    <span class="glyphicon glyphicon-thumbs-up"></span> I show up when your checkbox is checked.

  <div class="check-element animate-show" ng-hide="checked">
    <span class="glyphicon glyphicon-thumbs-down"></span> I hide when your checkbox is checked.
  </div>
</div>

protractor.js
var thumbsUp = element(by.css('span.glyphicon-thumbs-up'));var thumbsDown = element(by.css('span.glyphicon-thumbs-down'));

it('should check ng-show / ng-hide', Function() {
  expect(thumbsUp.isDisplayed()).toBeFalsy();
  expect(thumbsDown.isDisplayed()).toBeTruthy();

  element(by.model('checked')).click();
