如何在Angular中创建动态ng模型 [英] How to create Dynamic ng-model in Angular
问题描述
如何在Angular中创建动态ng模型?我尝试过，但是我想让它运行起来很困难.我得到的是不确定的.这是我的代码.
How can I create dynamic ng-models in Angular? I tried but I think I'm having a hard time getting it to run. All I get is undefined. Here's my code.
<input type="text" class="form-control input-sm" ng model="teller[value.teller_id]" value="<% value.mac_address %>">
我打算拥有一个具有相同名称但只能按数字更改的ng模型.我有一个可容纳1-4的数字的对象.这是value.teller_id.我想将其附加到ng-model中，如teller1，teller2，teller3(teller [value.teller_id]等.)由ng-repeat循环播放，我没有任何问题，但可以创建动态ng-model和更改数字将产生不确定的结果.
I am planning to have a ng-model that has the same name but only changes by number. I have an object that holds the number from 1-4. which is value.teller_id. I want to append it to the ng-model as teller1,teller2,teller3 (teller[value.teller_id] etc.. It is looped by ng-repeat which I don't have any problem but rather creating the dynamic ng-model and changing the number will yield undefine.
ng model="teller[value.teller_id]" <---- doesn't work
我想达到出纳员1，出纳员2等.
I want to achive teller1, teller2 etc..
谢谢！
推荐答案
是.我们可以动态生成ng-model名称.
Yes. We can generate ng-model name dynamically.
var app = angular.module('myApp', []);
app.controller('MainCtrl', function($scope) {
$scope.teller = {};
$scope.name = [{
"id":1
},{
"id":2
}]
});
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.28/angular.min.js"></script>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body ng-controller="MainCtrl">
<div ng-repeat="x in name">
<input type="text" ng-model="teller[x.id]" />
</div>
<pre>{{teller | json}}</pre>
</body>
</html>
