AngularJS:ng-repeat 中的 ng-model? [英] AngularJS: ng-model inside ng-repeat?

问题描述

我正在尝试使用 ng-repeat 生成表单输入.注意:'customFields' 是一个字段名称数组:["Age", "Weight", "Ethnicity"].

 
<label class="control-label">{{field}}</label><div class="控件"><input type="text" ng-model="person.customfields.{{field}}"/>

设置ng-model"的最佳/正确方法是什么?我想将它作为 person.customfields.'fieldname' 发送到服务器，其中 fieldname 来自 'field in customFields'.

解决方案

<div class="control-group" ng-repeat="customFields 中的字段"><label class="control-label">{{field}}</label><div class="控件"><input type="text" ng-model="person.customfields[field]"/>

<button ng-click="collectData()">Collect</button>

功能Ctrl($范围){$scope.customFields = ["年龄", "体重", "种族"];$scope.person = {自定义字段:{年龄":0，权重":0，种族":0}};$scope.collectData = 函数 () {控制台日志($scope.person.customfields)；}}

您可以在这里尝试一下.

对于验证，诀窍是将 放在转发器中.请尝试.

I'm trying to generate form inputs with ng-repeat. Note: 'customFields' is an array of field names: ["Age", "Weight", "Ethnicity"].

 <div class="control-group" ng-repeat="field in customFields">
   <label class="control-label">{{field}}</label>
     <div class="controls">
       <input type="text" ng-model="person.customfields.{{field}}" />
     </div>
 </div>

What is the best/correct way to set 'ng-model'? I would like to send it to the server as person.customfields.'fieldname' where fieldname comes from 'field in customFields'.

解决方案

<div ng-app ng-controller="Ctrl">
    <div class="control-group" ng-repeat="field in customFields">
        <label class="control-label">{{field}}</label>
        <div class="controls">
            <input type="text" ng-model="person.customfields[field]" />
        </div>
    </div>
    <button ng-click="collectData()">Collect</button>
</div>

function Ctrl($scope) {
    $scope.customFields = ["Age", "Weight", "Ethnicity"];
    $scope.person = {
        customfields: {
            "Age": 0,
                "Weight": 0,
                "Ethnicity": 0
        }
    };

    $scope.collectData = function () {
        console.log($scope.person.customfields);
    }
}

You can try it here.

Updated:

For the validation, the trick is to put <ng-form> inside the repeater. Please try.
