单击按钮后，如何获取属性type = hidden和name = price

Answer 1

此jQuery示例处理添加按钮的click事件，并找到同级 price 。它将这个值写入控制台。

请查看，

siblings()-DOM遍历功能

CSS Attribute Selectors

$("input.btn[name='add']").click(function(e) { //the click of the add button
  console.log($(this).siblings("input[type='hidden'][name='price']").val()); //write the val of the hidden field
});

<div class="col-md-4">


  <div style="border: 1px solid #ddd">
    <img width="10" height="10" src="">
    <h4 class="text-info"></h4>
    <h4 class="text-info"></h4>
    <input type="number" class="form-control" value="1" name="quantity">
    <input type="hidden" name="name" value="one">
    <input type="hidden" name="price" value="$1">
    <input type="button" class="btn btn-success" name="add" value="Sepete Ekle" id="add">
  </div>

</div>
<div class="col-md-4">


  <div style="border: 1px solid #ddd">
    <img width="10" height="10" src="">
    <h4 class="text-info"></h4>
    <h4 class="text-info"></h4>
    <input type="number" class="form-control" value="2" name="quantity">
    <input type="hidden" name="name" value="two">
    <input type="hidden" name="price" value="$2">
    <input type="button" class="btn btn-success" name="add" value="Sepete Ekle" id="add">
