AngularJS: API: ng/directive/ngBind

ngBind

  1. - directive in module ng

ngBind 屬性告訴Angular使用所給表達式的值替換指定HTML元素的文本內(nèi)容，并且在表達式的值改變時更新文本內(nèi)容。

一般情況下，你不需要使用ngBind指令，可以使用像{{ expression }}形式的雙花括號來替換，達到同樣的效果并且只需少量命令。

使用 ngBind 替換 {{ expression }} 是更好的方法，在處于Angular編譯前的原生狀態(tài)時的模板被瀏覽器立即顯示時。由于ngBind只是一個元素屬性，當頁面載入時它創(chuàng)建的綁定對用戶是不可見。

這個問題的另一個替代解決方案是使用 ngCloak 指令。

指令信息

  • 這個指令執(zhí)行優(yōu)先級為0.

用法

  • 作為屬性使用: 
    <ANY
  ng-bind="">
...
</ANY>
  • 作為CSS類使用: 
    <ANY class="ng-bind: ;"> ... </ANY>

參數(shù)

參數(shù) 類型 詳述
ngBind expression

可求值表達式。

示例

在實時預(yù)覽文本框輸入名稱，文本框的下方會立即刷新問候信息。

index.html 
<script>
  angular.module('bindExample', [])
    .controller('ExampleController', ['$scope', Function($scope) {
      $scope.name= 'Whirled';
    }]);
</script>
<div ng-controller="ExampleController">
  Enter name: <input Type="text" ng-model="name"><br>
  Hello <span ng-bind="name"></span>!
</div>
protractor.js
it('should check ng-bind', Function() {
  var nameInput = element(by.model('name'));

  expect(element(by.binding('name')).getText()).toBe('Whirled');
  nameInput.clear();
  nameInput.sendKeys('world');
  expect(element(by.binding('name')).getText()).toBe('world');});
