AngularJS中有一个filterFilter函数用来对集合过滤,非常方便。 源代码大致如下: functionfilterFilter(){returnfunction(aray, expression comparator){if(!isArray(array))returnarray;varcomparatorType =typeof(comparator), predicates=[], evaluatedObjects=[]; predicates.check=function(value){for(varj = 0; j ...
2. 在controller和service中使用filter 我们的js代码中也可以使用过滤器,方式就是我们熟悉的依赖注入,例如我要在controller中使用currency过滤器,只需将它注入到该controller中即可,代码如下: app.controller('testC',function($scope,currencyFilter){ $scope.num = currencyFilter(123534); } 在模板中使用{{num}}...
app.controller('testC',function($scope,$filter){$scope.num = $filter('currency')(123534);$scope.date = $filter('date')(new Date(),"yyyy-MM-dd hh:mm:ss EEEE");} 可以达到同样的效果。好处是你可以方便使用不同的filter了。 小结 以上是关于angularJS中过滤器的一些基本用法,都非常的简单,小...

除了像上面那样传递一个对象来过滤数据,还可以自定义一个过滤函数,返回true将加入结果集 ``` $scope.projectList = $filter('filter')($scope.projectList, function(value, index, array) { // console.log(value, index); return value.projec != Project_id; }); ``` ...
