Question

<span ng-repeat="location in model.locations ">
    <input type="checkbox" ng-disabled="isDisabled" ng-model="locations.isChecked" ng-true-value="CHECKED" ng-false-value="UNCHECKED" ng-change="filterGrid(location)">
    <label>{{ location }}</label>
</span>

列表格式的数据i

0: "One"
1: "Two"
2: "Three"
3: "USA"
4: "India"
5: "Japan"
6: "China"



 $scope.model.locations = data.location;
    for(var i=0;i<$scope.model.locations.length;i++){
         if($scope.model.locations[i] == 'USA'){
        $scope.model.locations[i].isChecked ="CHECKED"
        }
    }

但是我无法将USA设为默认值，可能是因为这是字符串格式。

请建议

我相信你可以使用ng-checked： Angularjs doc on ng-checked

我尝试了，我默认拥有它，这里是我的代码：

main.js

  $scope.locations = [
{ name : "One"},
{ name : "Two"},
{ name : "Three"},
{ name : "USA"},
{ name : "India"},
{ name : "Japan"},
{ name : "China"} ];

main.html中

<span ng-repeat="location in locations">
  <input type="checkbox" ng-checked="location.name == 'USA'">
  <label>{{ location.name }}</label>
</span>

我希望它会有所帮助。

如何选中默认复选框？
