Binding using ng-model inside ng-repeat in angularjs
提问by shahalpk
I'm trying to bind a model 'User' to a list of input fields. I do not know the fields beforehand, so i've to write a generic code to setup the form based on the fields.
我正在尝试将模型“用户”绑定到输入字段列表。我事先不知道这些字段，所以我必须编写一个通用代码来根据这些字段设置表单。
<script>
function MyController($scope){
$scope.fields = ['name','password','dob'];
$scope.user1 = {name:"Shahal",password:"secret"}
};
</script>
<div ng-app ng-controller="MyController">
<ul>
<li ng-repeat="field in fields">
<label>{{field}}</label><input type="text" ng-model="user1.{{field}}">
</li>
</ul>
<pre>{{fields}}</pre>
</div>
I'm trying to loop through the fields and show a input field for each fields (available in scope). But the binding is not proper as i'm trying to evaluate an expression inside ng-model.
我正在尝试遍历字段并显示每个字段的输入字段（在范围内可用）。但是绑定不正确，因为我正在尝试评估 ng-model 中的表达式。
Basically i'm trying to show 3 input fields (name,password,dob) with the object user1 attached to the corresponding field.
基本上，我试图显示 3 个输入字段（名称、密码、dob），并将对象 user1 附加到相应的字段。
