在AngularJS前pression嵌入HTML标记通常不是因为这样你将不能够评估AngularJS指令的***途径。

不管怎样，回到你的问题 - 大约有你的问题得到的许多方面。如果你只是显示链接最简单的方法去将是使用 NG-绑定-HTML 指令之后（http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml):

 ＆LT;警报NG重复=警戒警报中TYPE =alert.type亲密=closeAlert（$指数）＆GT;
    ＆LT;跨度NG绑定-HTML =alert.msg＆GT;＆LT; / SPAN＆GT;
  ＆LT; /警报＆GT;

How do I include links in an angular-ui bootstrap alert?

Attempt:

Plunker Example

HTML

<div ng-controller="AlertDemoCtrl">
    <alert ng-repeat="alert in alerts" type="alert.type" close="closeAlert($index)">{{alert.msg}}</alert>
    <button class='btn' ng-click="addAlert()">Add Alert</button>
</div>

Script

function AlertDemoCtrl($scope) {
  $scope.alerts = [
    { type: 'error', msg: 'Oh snap! Change a few things up and try submitting again.' }, 
    { type: 'success', msg: '<a href="">Well done!</a> You successfully read this important alert message.' }
  ];

  $scope.addAlert = function() {
    $scope.alerts.push({msg: "Another alert!"});
  };

  $scope.closeAlert = function(index) {
    $scope.alerts.splice(index, 1);
  };

}

Embedding HTML markup in AngularJS expression is usually not the best approach as this way you won't be able to evaluate AngularJS directives.

Anyway, coming back to your question - there are many ways of getting around your problem. If you are just after displaying links the simplest way to go would be to use the ng-bind-html directive (http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml):

  <alert ng-repeat="alert in alerts" type="alert.type" close="closeAlert($index)">
    <span ng-bind-html="alert.msg"></span>
  </alert>
