【问题描述】:
我在 angularJs 中创建了简单的自定义指令。在该指令中,我将一组对象作为 tableLayout 传递。请查看我的工作 jsfiddle 没有错误。
但是我需要传递一个过滤的 tableLayout。我在名为 filterFilterFn 的范围内创建了一个函数来过滤值,然后将其传递到我的指令的范围内。当我这样做时,我得到一个 $rootScope:infdig 错误。
Js Fiddle w/ filterFunction NOT working
阅读另一个类似的问题,它与在 angularJs 中使用默认过滤器有关。因此,为什么我在范围内完成了自定义过滤器功能。但我仍然遇到同样的错误。关于我做错了什么的建议将不胜感激。
下面的非工作代码:
<div ng-app="myApp" ng-controller="mainCtrl">
<script type="text/ng-template" id="/template">
<button ng-click="testFn()">Test</button>
<div layout="row">
<div flex ng-repeat="col in [1,2,3]"><span>HEADER{{$index}}</span>
<div layout="column">
<div flex style="border: 1px solid black;" ng-repeat="row in [1,2,3]">{{$index}}</div>
</div>
</div>
</div>
</script>
<button ng-click="testFn()">Test 2</button>
<form-table table-layout=formFilterFn('table_id',1)></form-table>
</div>
var app = angular.module('myApp', ['ngMaterial']);
app.controller('mainCtrl', function($scope) {
$scope.tableLayout =[{"head_id":"GAP Assessment","table_id":"1","table_name":"GAP Table","element_id":"0","element_name":"Action Reference","sort_order":"0","is_multirow":"1","flex":"30","element_sort_order":"4","is_show":"0"},{"head_id":"GAP Assessment","table_id":"1","table_name":"GAP Table","element_id":"1","element_name":"Audit Criteria","sort_order":"0","is_multirow":"1","flex":"30","element_sort_order":"0","is_show":"1"},{"head_id":"GAP Assessment","table_id":"1","table_name":"GAP Table","element_id":"3","element_name":"Document Reference","sort_order":"0","is_multirow":"1","flex":"10","element_sort_order":"3","is_show":"1"},{"head_id":"GAP Assessment","table_id":"1","table_name":"GAP Table","element_id":"4","element_name":"Findings - General","sort_order":"0","is_multirow":"1","flex":"20","element_sort_order":"1","is_show":"1"},{"head_id":"GAP Assessment","table_id":"1","table_name":"GAP Table","element_id":"5","element_name":"Findings Details","sort_order":"0","is_multirow":"1","flex":"40","element_sort_order":"2","is_show":"1"}]
$scope.testFn=function(){
console.log("Test");
}
$scope.formFilterFn = function(key,value){
var output = [];
var input = $scope.tableLayout;
for (var x =0; x < Object.keys(input).length; x++){
if (input[x][key]==value){
output.push(input[x]);
}
}
return output;
}
});
app.directive('formTable', function() {
return {
scope:{tableLayout:'='},
link: function(scope,element,attrs){ // normal variables rather than actual $scope, that is the scope data is passed into scope
scope.column=[1,2,3];
scope.testFn=function(){
console.log(scope.tableLayout);
}
//function and scopes go here
},//return
transclude:true,
templateUrl: '/template',
restrict: 'E'
}
})
