{{ item.Service_Categories}}
</label>
</div>
<input type="submit" name="submit" value="submit"/>
</form>
$scope.check= function() {
//console.log("a");
$http.get('XYZ.com').success(function(data, status,response) {
$scope.items=data;

Can I suggest reading the answer I posted yesterday to a similar StackOverflow question..
我可以建议阅读我昨天发布的类似 StackOverflow 问题的答案吗？
This displayed a few checkboxes, then bound them to an array, so we would always know which of the boxes were currently checked.
这显示了一些复选框，然后将它们绑定到一个数组，因此我们总是知道当前选中了哪些框。
And yes, you could ignore the contents of this bound variable until the submit button was pressed, if you wanted to.
是的，如果您愿意，您可以忽略此绑定变量的内容，直到按下提交按钮。

As per your code all the checkboxes values will be available in the typeValues array. You can use something like this in your submit function:
根据您的代码，所有复选框值都将在 typeValues 数组中可用。你可以在你的提交函数中使用这样的东西：
$scope.typeValues
If you want to access the value of 3rd checkbox then you need to do this:
如果要访问第三个复选框的值，则需要执行以下操作：
var third = $scope.typeValues[2];

Declare your ng-modelas array in controller, like
ng-model在控制器中声明你的数组，比如
$scope.typeValues = [];
And in your template, please use
在您的模板中，请使用
ng-model="typeValues[item._id]"
And in your controller, you will get this model array valuesin terms of 0and 1. You can iterate over there.
在您的控制器中，您将model array values根据0和获得此信息1。你可以在那里迭代。
