angularjs中的ng-src和ng-href

魔豆發表於2016-09-13

ng-src和ng-href等同於html中的src和href,只是ng是在dom載入完畢之後才能夠發揮作用,如果在src或href中繫結變數,如果ng沒有載入完,會導致連結地址出錯,如果用對應的ng-src或ng-href,則不會出現這個問題。下面是一段示例程式碼:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="UTF-8">
<title>interval</title>
<script type="text/javascript" src="angular.min.js" charset="utf-8"></script>
</head>
<body ng-controller="ctrl">

<div><a ng-href="NewFile3_{{i}}.htm">連結</a></div>
<div><input type="button" ng-click="clickEvent(1)" value="切換連結1" /><input type="button" ng-click="clickEvent(2)" value="切換連結2" /><input type="button" ng-click="clickEvent(3)" value="切換連結3" /></div>
<script type="text/javascript">
var myApp = angular.module('myApp',[]);
myApp.controller('ctrl', function($scope){
    $scope.i = 1;
    $scope.clickEvent = function(index) {
        $scope.i = index;
    }
});
</script>
</body>
</html>
