出于某种原因,当我在资源1和资源2之间切换时,我的控制器被双重调用.
这是代码：
的index.html
<!DOCTYPE html>
<html ng-app="multiple_calls">
<head>
<Meta charset="utf-8" />
<title>AngularJS Plunker</title>
<link rel="stylesheet" href="style.css" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<a href="#res/1">1</a>
<a href="#res/2">2</a>
<div ng-view>
</div>
</body>
</html>
app.js
var app = angular.module('multiple_calls',[]);
app.
config(['$routeProvider',function($routeProvider) {
$routeProvider.
when('/res/:id',{templateUrl: 'res.html',controller: 'res'
});
}]);
app.controller('MainCtrl',function($scope) {
});
app.controller('res',function($scope,$routeParams) {
console.log('resource called')
$scope.id = $routeParams.id;
});
res.html
{{id}}

如果单击项目1然后单击2,您将看到“资源调用”打印3次：资源之间每次更改2次.
任何线索为什么会发生这种情况？
解决方法
发现一个完全相同的问题：
AngularJs: controller is called twice by using $routeProvider
解决方案是在路由器URL的末尾添加“/”：
- when('/res/:id',+ when('/res/:id/',
