所以我无法真正实现这一点,我有以下代码
HTML:
<!doctype html>
<html ng-app="plunker" >
<head>
<meta charset="utf-8">
<title>AngularJS Plunker</title>
<link rel="stylesheet" href="style.css">
<script>document.write("<base href=\"" + document.location + "\" />");</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
{{vt.t}}
<div my-directive="{{vt.t}}"></div>
{{vt.f}}
<div my-directive="{{vt.f}}"></div>
<hr />
{{vt.t}}
<div ng-class="{'my-directive': vt.t}"></div>
{{vt.f}}
<div ng-class="{'my-directive': vt.f}"></div>
<hr />
<div class="my-directive"></div>
<div class="nodirectiveclass"></div>
</body>
</html>
JavaScript的:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.vt = { t: true, f: false };
});
app.directive('myDirective', function($compile) {
return {
restrict: 'AC',
template: '<div>Directive on</div>',
replace: true
};
});

如您所见,动态添加时类不会触发指令,但在我上一个“静态”示例中工作正常。我也尝试将directive属性设置为true或false,但这似乎没有帮助。

我认为你应该在你的指令中使用模型变量。然后,您可以轻松访问您想要的价值。
