AngularJS：NG-模式不绑定到NG-检查复选框 [英] AngularJS: ng-model not binding to ng-checked for checkboxes
问题描述
我提到了这个问这个问题之前。
I referred to this before asking this question.
<一个href=\"http://stackoverflow.com/questions/14226439/angularjs-doesnt-bind-ng-checked-with-ng-model\">AngularJs不绑定NG-检查与NG-模型
如果 NG-检查进行评估，以<code>真正在 HTML 端， NG-模型不更新。我不能 NG-重复所建议的上述问题，因为我必须使用一些造型为每个复选框。
If ng-checked is evaluated to true on the html side, the ng-model is not updated. I can't ng-repeat as suggested in the above question because I have to use some styling for each checkbox.
下面是我创造来说明我的问题plunker。
Here is the plunker that I have created to illustrate my problem.

要看到我想要的东西，请打开控制台，只需点击提交按钮。请不要检查任何复选框。
To see what I want, please open the console, and just click on Submit button. Please don't check any checkboxes.
在此先感谢！
推荐答案
ngModel 和 ngChecked 并不意味着可以一起使用。
ngModel and ngChecked are not meant to be used together.
ngChecked 是说期待一个前pression，所以 NG-检查=真，你基本上说，该复选框将始终默认进行检查。
ngChecked is expecting an expression, so by saying ng-checked="true", you're basically saying that the checkbox will always be checked by default.
您应该能够只使用 ngModel ，拴在你的模型布尔属性。如果你想要别的东西，那么你要么需要使用 ngTrueValue 和 ngFalseValue （只支持字符串现在），或者自己写指令。
You should be able to just use ngModel, tied to a boolean property on your model. If you want something else, then you either need to use ngTrueValue and ngFalseValue (which only support strings right now), or write your own directive.
究竟是什么，你想干什么？如果你只是想在默认情况下进行检查的第一个复选框，你应该改变你的模型 - ITEM1：真，
What is it exactly that you're trying to do? If you just want the first checkbox to be checked by default, you should change your model -- item1: true,.
编辑：您不必提交表单调试模型的当前状态，顺便说一句，你可以转储 {{} testModel} 到HTML （或＆LT; pre＆GT; {{testModel | JSON}}＆LT; / pre＆GT; ）。此外，您的 ngModel 属性可以简化为 NG-模式=testModel.item1。
You don't have to submit your form to debug the current state of the model, btw, you can just dump {{testModel}} into your HTML (or <pre>{{testModel|json}}</pre>). Also your ngModel attributes can be simplified to ng-model="testModel.item1".
