在 ng-repeat 中生成 ng-model [英] Generate ng-model inside ng-repeat

问题描述

我一直在阅读一些主题，但找不到解决这个问题的方法.

I have been reading a few topics but couldnt find a solution to this one I am stuck on.

我正在尝试将 ng-model 添加到 ng-repeat 中，如下所示:

I am trying to add ng-model inside ng-repeat something like this:

<span ng-repeat="list in lists">
         <input type="checkbox" ng-model="formData.checkboxes.{{ list.value }}"> {{ list.number }} {{ list.description }} <br/>
</span>

和列表值是这样的:

$scope.lists = [

    {

        value:'value1',
        number: '1',
        description:'Lorem ipsum dolor sit amet, consectetur adipiscing elit. ',    
    },

    {
        value:'value2',
        number: '2',
        description:'Lorem ipsum dolor sit amet, consectetur adipiscing elit. ', 
        },

        {
        value:'value3',
        number: '3',
        description:'Lorem ipsum dolor sit amet, consectetur adipiscing elit. ',            },
    ];

在 ng-repeat 循环中，我希望它构建一个 ng-model，如:formData.checkboxes.value1 formData.checkboxes.value2, formData.checkboxes.value3 等等.

Inside the ng-repeat loop, I want it to build a ng-model like: formData.checkboxes.value1 formData.checkboxes.value2, formData.checkboxes.value3 etc..

这可能吗?当我尝试上述方法时，没有任何显示.我在这里做错了什么?

Is this possible? When I try the above method nothing shows up. What am I doing wrong here?

推荐答案

首先你应该像这样在控制器中定义 formData.checkboxes 模型:

First you should define formData.checkboxes model inside your controller like this:

$scope.formData = {
    checkboxes: {}
};

...你可以像这样填充它:

... and the you can populate it like that:

<span ng-repeat="list in lists">
    <input type="checkbox" ng-model="formData.checkboxes[list.value]"/> 
             {{ list.value }} {{ list.number }} {{ list.description }} <br/>
</span>
