AngularJS错误:fnPtr不是函数

angularjs

我正在尝试编写示例AngularJS和SpringMVC项目。spring方法可以正常工作,但是我的站点控制器中的函数声明存在问题。我的应用应该从文本输入中返回一个单词,但是当我单击按钮时,出现了以下错误:

[13:23:58.900] "Error: fnPtr is not a function
parser/_functionCall/<@http://localhost:8080/example/resources/js/Angular/angular.js:6542

"

这是我的index.html:

<!DOCTYPE html>
<html lang="en" ng-app="Apken">
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script src="resources/js/Angular/angular.js"></script>
<script src="resources/js/controler.js"></script>

</head>
<body ng-controller="theNamer">

<div class="input-append">
    <input style="width:358px;" class="span2" type="text" ng-model="myName" required min="1" />
    <button class="btn btn-primary" ng-disabled="!myName" ng-click="send()">Click!</button>
</div>
<ul>
<li  ng-repeat="name in names">{{name}}</li>

</ul>

</body>
</html>

和controller.js:

function theNamer ($scope,$http){
    $scope.myName='aa';

    $scope.fetchList=new function()
    {
        $http.get('ca/list.json').success(function(thList){
            $scope.names = thList;
        });
    }

        $scope.send=new function()
        {

            $http.post('ca/set/3').success(function(){

            $scope.fetchList;

            });

        }
        $scope.fetchList;


}

var Apken = angular.module('Apken',[]);
Apken.controller('theNamer', theNamer);

我注意到,这一定是ng-click值中的函数声明存在某种问题。在现场启动时,controler.js可以正常运行,但是当我单击该按钮时它会崩溃。

我已经测试过您的代码。使用AngularJS 1.0.7,替换后错误消失

$scope.send = new function() {

$scope.send = function () {

同样适用于fetchList

我猜您混合了两种语法function(*args*) { *body* }new Function(*args*, *body*)。检查MDN:功能

您还必须更改代码才能fetchList正确调用您的代码:

function theNamer($scope, $http) {

        $scope.myName = 'aa';

        $scope.fetchList = function() {

            $http.get('ca/list.json').success(function(thList) {

                $scope.names = thList;

            });

        };

        $scope.send = function() {

            $http.post('ca/set/3').success(function() {

                $scope.fetchList();

            });

        };

        $scope.fetchList();

}
