AngularJS-根據當前路徑更改href屬性

Question

如何根據當前路徑更改href-Attribute的值？

我在AngularJS中的if子句看起來像這樣：

    if (newPath.indexOf('test') > -1) {
      // change the value of the href-Attribute
    } else {
      // don't change the value of the href-Attribute
    }

我的HTML看起來像這樣：

    <li>
      <a aria-expanded="false" role="button" href="/path1/path2/path4">Downloads</a>
    </li>

Answer 1

您可以使用ng-href將值動態分配給href

<li>
  <a aria-expanded="false" role="button" ng-href="{{myVar}}">Downloads</a>
</li>

$scope.myVar ="/path1/path2/path4";

if (newPath.indexOf('test') > -1) {
      $scope.myVar = "/path1/path2/path4" // you can assign whatever path to this variable 
} else {
      $scope.myVar = "/path1/path2/path3" // you can assign whatever path to this variable
}

Answer 2

您可以使用獲取當前路徑

var url = $location.absUrl().split('?')[0];

替換href屬性

var myEl = angular.element( document.querySelector( '#selector' ) );
myEl.attr('href',url);

Answer 3

 if (newPath.indexOf('test') > -1) {
      $scope.newPath = newPath.test;
    } else {
      // don't change the value of the href-Attribute
    }

<li>
      <a aria-expanded="false" role="button" ng-href="{{newPath}}">Downloads</a>
    </li>
