我正在尝试根据$ index对这个ng-repeat中的项目进行拼接。它可以很好地添加它们，但是当我尝试使用相同的代码删除该项时，它只删除数组的最后一项，就好像它正在执行pop（）方法一样。我不知道为什么。这是我的目标，我正在重复：
"lineItems": [
{
"area": "Bedroom",
"label": "Sleep Time",
"notes": "",
"pictures": [],
"subLineItems": [

},
{
"label": "Dirty",
"value": "3",
"color": "dirty-yellow"
},
{
"label": "Fair",
"value": "4",
"color": "fair-light-blue"
},
{
"label": "Good",
"value": "5",
"color": "good-green"
}
]
},
"items": [
[
{

},
{

],

}
这是我的HTML：

这是我的控制器：
//add line item when NEW button is pressed
$scope.add = function(a, b){
//create the source of the copy, and where you want to send it (destination is a blank array)
var mySource = $scope.lineItems[0].subLineItems[0].items[0];
var myDestination = [];
//copy the source and send it to destination
angular.extend( myDestination, mySource);
//push that newly built array into the array
$scope.lineItems[a].subLineItems[b].items.push(myDestination);
//show the updated version of that array
console.log( $scope.lineItems[a].subLineItems[b].items);
};
//remove item from array
$scope.removeItem = function(a, b, c){
console.log(a, b, c);
$scope.lineItems[a].subLineItems[b].items.splice(c, 1);
console.warn($scope.lineItems[a].subLineItems[b].items);
};
这会在控制台中输出正确的数字，但实际上会删除items数组中的最后一项。任何想法？
答案 0 :(得分：0)
问题在于您的父标记。
removeItem($parent.$parent.$index, $parent.$index, $index)
这里，$parent是根据你的html中的分区而不是根据数组。
尝试一些其他逻辑来定位子阵列。
