如何通过jquery

标签： javascript jquery html css checkbox

我已根据我网站上的复选框实施了切换开关。当我使用一个切换开关时，我可以获取我单击的复选框的值。但是当我实现两个或更多切换开关时，我无法获得单击复选框的值。它总是返回复选框的第一个值。

你可以通过点击我在下面的小提琴上创建的第二个切换开关来理解我所说的内容。

这是我的HTML代码：

<div class="switch" id="switch">
  <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round" type="checkbox" checked data-value="one" >
  <label for="cmn-toggle-1"></label>
</div>

<br>

<div class="switch" id="switch">
  <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round" type="checkbox" data-value="two">
  <label for="cmn-toggle-1"></label>
</div>

这是我的jQuery代码：

$(document).on("change", ".switch", function () {
    alert($(this).find('input').data('value'));
});

您已复制两个swtiches的ID。请在下面找到更正后的代码

<div class="switch" id="switch">
  <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round" type="checkbox" checked data-value="one" >
  <label for="cmn-toggle-1"></label>
</div>

<br>

<div class="switch" id="switch">
  <input id="cmn-toggle-2" class="cmn-toggle cmn-toggle-round" type="checkbox" data-value="two">
  <label for="cmn-toggle-2"></label>
</div>


$(document).on("change", ".switch", function () {
	alert($(this).find('input').data('value'));
});
