如何绑定2款至一个输入场角？ [英] How to bind 2 models to one input field in Angular?

问题描述

反正是有，我可以结合两种模式，一个输入字段？假设我有我要在范围内的东西就像两个变量的值输入字段：

 ＆LT;输入类型=文本模式=sn_number; ID＆GT;
 

解决方案

您不能，但也有一些解决办法。

1。使用ngChange更新其他模型

 ＆LT;输入类型=文本
       NG-模式=sn_number
       NG-变化=ID = sn_number/＆GT;
 

2。你可以观看模式，而当变化，更新另一个

  $范围。$腕表（'sn_number'，函数（五）{
  $ scope.id = V;
}）;
 

您需要还来观察 ID 的变化，如果你想保持同步。

例这里

is there anyway that i can bind two model to one input field ? Suppose I have input field which I want to be the value of two variables in the scope something like:

<input type="text" model="sn_number; id" > 

解决方案

You cannot, but there are some workarounds.

1. Use ngChange to update the other model

<input type="text" 
       ng-model="sn_number" 
       ng-change="id=sn_number"/> 

2. You could watch a model, and when in changes, update another

$scope.$watch('sn_number', function(v){
  $scope.id = v;
});

You would need to watch also for changes in id if you want to keep them in sync.
