如何获取所选单选按钮的值

问题描述

我的HTML部分如下:

My HTML part is below:

<input id="yes" save-value="yes" value="no" name="view_y" class="switch-input yes" type="radio">
<label checked="checked" class="switch-label switch-label-off selected" for="yes">Yes</label>
<input id="no" save-value="no" value="no" name="view_n" class="switch-input no" type="radio">
<label class="switch-label switch-label-on" for="no">No</label>
<span class="switch-selection"></span>

当我单击每个按钮的"checked ="checked"时，所选选项将从"yes"变为"no"标签.

When I click each button checked="checked" and selected options will be changing from yes to no labels.

使用这些选项，如何获得所选单选按钮的保存值.因为，我在我的value选项上使用了Handlebars js(json)，所以我想获取所选单选按钮的保存值.

With these options, how can I get the save-value of selected radio button. Since, am using Handlebars js (json) on my value option I want to get the save-value of selected radio button.

我该怎么做?

推荐答案

假定类switch-input仅分配给这两个输入元素，则可以将其与选中的选择器一起使用

Assuming the class switch-input is assigned to only these two input elements, you can use it along with the checked selector

var value = $('input.switch-input').filter(':checked').attr('save-value');
//or var value = $('input.switch-input:checked').attr('save-value');

注意:更喜欢使用data- *属性来存储自定义属性

Note: Prefer to use data-* attributes to store custom attributes

我认为单选按钮实际上并没有得到检查，只是标签属性被更改，因此，向myclass

I think the radio buttons are not actually getting checked, only the labels attributes are changed so, add a additional class to the labels like myclass

<input id="yes" save-value="yes" value="no" name="view_y" class="switch-input yes" type="radio"/>
<label checked="checked" class="myclass switch-label switch-label-off selected" for="yes">Yes</label>
<input id="no" save-value="no" value="no" name="view_n" class="switch-input no" type="radio"/>
<label class="myclass switch-label switch-label-on" for="no">No</label>
<span class="switch-selection"></span>

然后

var value = $('.myclass[checked="checked"]').prev('input').attr('save-value');
console.log(value)
