Angularjs assigning value to ng-model using ng-init

Question

Hi I have following issue which seems easy and should work but is not.

In my code I have input

 <input type="text"  ng-model="c.Id"  ng-init="c.Id={{pId}}"/>

When I look at the DOM using firebug tool I see the value

 <input type="text"  ng-model="c.Id"  ng-init="c.Id=6"/>

But it wont display 6 in the input box neither I can access it using #scope. Please let me know what is wrong here and how to fix it so that ng-model can have from ng-init. Thanks

Answer 1

Get rid of the braces in the expression so that it will evaluate pId directly from the scope

<input type="text"  ng-model="c.Id"  ng-init="c.Id=pId"/>

Answer 2

ng-init采用表达式，因此不需要花括号：

<input type="text"  ng-model="c.Id"  ng-init="c.Id=pId"/>

Answer 3

Assigning the value to ng-model using ng-value

   <input type="text" class="form-control" ng-model="inputPrice" />
   <input type="text" ng-model="newPrice" ng-value="newPrice=inputPrice" />
