第一次迭代中我的手风琴使用ng-repeat https://jsfiddle.net/cs3rpy83/6/
但是当我在onclick =“myFunction（'{{section.id}}'）中使用表达式时，”它不再打开了，请参阅https://jsfiddle.net/cs3rpy83/14/为什么？
<title>The W3.CSS Example</title>
<body ng-app ng-init="app='accordion'">
<div class="w3-accordion w3-light-grey" ng-init="sections=[{'id':'section1', title:'Open Section 1'},{'id':'section2', title:'Open Section 2'}]">
<div ng-repeat= "section in sections" >
<button onclick="myFunction('{{section.id}}')" class="w3-btn-block w3-left-align">
{{section.title}}
</button>
<div id="{{section.id}}" class="w3-accordion-content w3-container">
<p>Some text..</p>
</div>
</div>
</div>
</body>
我也遇到标签http://www.w3schools.com/w3css/tryit.asp?filename=tryw3css_tabulators
的问题不同之处在于有一个事件要通过 我试图在$ scope.openCity = function（cityName）中使用$ event但仍然无效：

答案 0 :(得分：3)
您必须在开发者控制台中遇到以下问题。
不允许使用HTML DOM事件属性的插值。请改用ng版本（例如ng-click而不是onclick）。
请在此处阅读其禁止的原因：https://docs.angularjs.org/error/ $ compile / nodomevents
这特别告诉您应该使用ng-click并在控制器中创建功能
$scope.myFunction = function(id)
{
}
在视图中
<button ng-click="myFunction(section.id)" class="w3-btn-block w3-left-align">
工作示例
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope) {
$scope.myFunction = function(id) {
var x = document.getElementById(id);
if (x.className.indexOf("w3-show") == -1) {
x.className += " w3-show";
} else {
x.className = x.className.replace(" w3-show", "");
}
}
