问题描述
我在AngularJS中使用dotdotdot JQuery插件时遇到了小问题。 有我的HTML代码:
<div class="col-md-2 col-sm-6 col-xs-12" ng-repeat="video in videos track by $index">
<a href="{{thumbsPath + video.thumbnail}}" class="thumb">
<div class="thumbnail">
<img ng-src="{{thumbsPath + video.thumbnail}}" alt="">
<div class="caption">
<p class="video-title" dotdotdot>{{video.name}}</p>
</div>
</div>
</a>
</div>
这是我的dotdotdot指令:
videoControllers.directive('dotdotdot', function() {
return function(scope, element, attrs) {
$(element).dotdotdot({'watch':true});
};
});
我想缩短{{video.name}},但是当我添加点号时-它不会显示{{video.name}}的内容,而是显示文本:“ {{video.name}}”。 我几乎阅读了有关该主题的所有帖子,但没有任何帮助。

您应该在指令中调用scope。$ apply。 这将导致您的控制器更新模型。 请参阅下面的示例

需要添加require:'ngModel'以便每次更新

原来,您应该使用指令的compile属性,而不是在ng-repeat中使用指令时链接
var app = angular.module('myApp', []); app.controller('myController', function($scope) { $scope.videos = [{ name: 'Pool', thumbnail: 'http://img.youtube.com/vi/dXo0LextZTU/0.jpg' }, { name: 'Pool2', thumbnail: 'http://www.shender.com/db_picture/pro19/201105251714246730.jpg' }]; }); app.directive('dotdotdot', function() { return { restrict: 'A', compile: function(scope, element, attrs) { return { pre: function(scope, element, attrs) { $(element).dotdotdot({ 'watch': true }); } }; } }; });
