[英]AngularJs ng-repeat is register two click event on checkboxes?
https://jsfiddle.net/ytygc19t/2/ https://jsfiddle.net/ytygc19t/2/
HTML: HTML:
<div ng-app="app" ng-controller="MainCtrl">
<span>Test App @ </span> status:{{loaded}}
<hr>
<div ng-repeat="checkbox in checkBoxArray track by $index">{{checkbox}}
<input name="x{{checkbox}}" id="x{{checkbox}}" ng-click="removeCheckBox(checkbox)" type="checkbox"/>
</div>
</div>
JS: JS:
angular.module("app",[])
.controller("MainCtrl", ["$scope", "$timeout", function($scope, $timeout){
$scope.checkBoxArray = ["a", "b", "c", "d", "e"]
$scope.loaded = "loaded";
$scope.removeCheckBox = function (value){
$timeout(function(){
$scope.checkBoxArray.splice($scope.checkBoxArray.indexOf(value), 1);
}, 300)
}
}])
When i check checkbox a, a is removed, and b is also checked 当我选中复选框a时,a被删除,b也被选中
Remove track by $index
because everytime a is selected, then a is removed and that time b index will become 1 so it is getting checked. track by $index
删除track by $index
因为每次选择a时,都将删除a,而此时b索引将变为1,因此将对其进行检查。

I think what you're experiencing is a clash between HTML checkbox functionality and Angular functionality. 我认为您遇到的是HTML复选框功能和Angular功能之间的冲突。 Try tracking the checkbox value using angular.
尝试使用角度跟踪复选框的值。
<li ng-repeat="item in Items">
<label>{{item.Name}}
<input type="checkbox" ng-model="item.Selected" ng-click="item.Selected = true" />
</label>
</li>
And in the controller 并在控制器中
$scope.Items = [{Name: 'bla', Selected: false}, ...]
Also, is there any particular reason you need track by $index ?
此外,是否有任何特定原因需要您按$ index进行跟踪 ? That could be giving you some problems as well.
那也可能给您带来一些问题。
