相关疑难解决方法(0)

仅当ng-if中的条件为真时才可以调用方法吗？我有这样的重复

<div ng-repeat="i in items" ng-if="i.loc == 'abc'">
    <h1>Hello.. {{getName()}}</h1>
</div>

这是js代码

$scope.getName = function() {
    console.log('fired');
    return "myName";
}

从控制台我可以看到这个方法比items.length和i.loc条件更多次.那么只有在ng-if为真时才能调用这个内部方法

我必须补充一点,我正在研究Sharepoint 2013,可视化网络部分.我的ascx:

<div ng-app="VODCatalogModule">
    <div class="wrapper" ng-view="">   
    </div>
</div>

我的JS:

var VODCatalogModule = angular.module('VODCatalogModule', []);

var testWPDefinedView = 'TopLevelView';

VODCatalogModule.config(function ($routeProvider) {
    $routeProvider.when('/TopLevelView', { controller: 'VODCatalogController', templateUrl: '/_catalogs/masterpage/html/VODCatalog_TopLevelView.html' })
                  .when('/LowLevelView', { controller: 'VODCatalogController', templateUrl: '/_catalogs/masterpage/html/VODCatalog_LowLevelView.html' })
                  .otherwise({ redirectTo: '/' + testWPDefinedView });
});

function VODCatalogController($scope, $http) {
    $scope.VODCatalogLevel = 1;
    $scope.BreadCrumbs = []; …
