记录angularjs中比较容易忽视的问题
1、关于动态生成ui-sref的问题 ui-route中ui-sref中的路径无法动态生成的,如果要实现动态生成ui-sref路径,可以使用$state.go做跳转:
if($location.path().substring(8,14) == 'zrssjg'){ $state.go('sousuo.zrssjg', {topic:$scope.keyWord}, { reload: true });}else if($location.path().substring(8,14) == 'dtssjg'){ $state.go('sousuo.dtssjg', {topic:$scope.keyWord}, { reload: true });}else if($location.path().substring(8,14) == 'nmssjg'){ $state.go('sousuo.nmssjg', {topic:$scope.keyWord}, { reload: true });}else if($location.path().substring(8,14) == 'htssjg'){ $state.go('sousuo.htssjg', {topic:$scope.keyWord}, { reload: true });}else if($location.path().substring(8,14) == 'zwssjg'){ $state.go('sousuo.zwssjg', {topic:$scope.keyWord}, { reload: true });}//ifelse==>$scope.doSerchClick = function(item) { $scope.sType = {'0':'sousuo.zrssjg', // 找人搜索结果 '1':'sousuo.dtssjg', // 实名动态 '2':'sousuo.nmssjg', // 匿名动态 '3':'sousuo.htssjg', // 话题 '4':'sousuo.zwssjg'}[item] || 'zrssjg'; // 职位 || 找人 $scope.keyWord = ''; }
2、使用$templateCache服务动态绑定html页面中ng-bind内容:
$scope.toTrends = function(type) {if (type == 1) { $templateCache.put('templateId.html', '{{reply.replier.realName}}:');$templateCache.put('template.html','{{data.dynamicRef.dynamicShare.publisher.realName}}:');} else { $templateCache.put('templateId.html','{{reply.replier.account.nickName}}:'); $templateCache.put('template.html','{{data.dynamicRef.dynamicShare.publisher.account.nickName}}:');} $scope.typeStatus = type; pushContent($scope.typeStatus);};//html:<span ng-include=" 'template.html' "></span>//这边的template.html能根据vontroller中的状态动态生成,同时也能实现双向绑定的效果
3、element匹配元素
angular.element(document.querySelector('.a'))
4.$sce服务
我们用ng-bind-html这样的指令来绑定一段动态生成的html,结果不是我们想要的,例如:$scope.currentWork.description = “hello,<br><b>今天我们去哪里?</b>”我们用ng-bind-html这样的指令来绑定,结果却不是我们想要的。是这样的hello,今天我们去哪里? 怎么办呢?、结果是将样式与html标记过滤掉了,我们可以使用$sce服务来解决这个问题:$scope.currentWork = work; $scope.currentWork.description = $sce.trustAsHtml($rootScope.currentWork.description); 把它封装成一个过滤器就可以在模板上随时调用了app.filter('to_trusted', ['$sce', function ($sce) {return function (text) { return $sce.trustAsHtml(text);};}]);html code:<p ng-bind-html="currentWork.description | to_trusted"></p>
