我正在尝试获取 value -我的<a>的属性-tag，在下面的示例中 999 。请参阅下面我的最小可行示例:
<!DOCTYPE html>
<html>
<head>
<title>Jquery Modal</title>
</head>

<script>
$(document).ready(function() {
//display modal form for product EDIT ***************************
$(document).on('click', '.open_modal', function() {
var cryptos_id = $(this).val();
console.log("cryptos_id: " + cryptos_id)
});
});
</script>
<body>
<div>
<tr>
<a id="coo99" value="999" class="open_modal" data-target="#myModal">
<sup> EDIT</sup>
</a>
</tr>
</div>
<!-- MODAL SECTION -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="myModalLabel">Edit</h4>
</div>
<div class="modal-body">
<form id="frmProducts" name="frmProducts" class="form-horizontal" novalidate="">
<div class="form-group error">
<label for="inputName" class="col-sm-3 control-label">Name: </label>
<div class="col-sm-9">
<input type="text" class="form-control has-error" id="name" name="name" placeholder="Country of Origin" value="">
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" id="btn-save" value="update">Edit Entry</button>
<input type="hidden" id="product_id" name="product_id" value="101">
</div>
</div>
</div>
</div>
</body>
</html>当您按EDIT时按钮crypto_id目前没有返回任何内容，但是我想获得 value - 属性 - 999 - 我的a -标记回来。
有什么建议我做错了什么吗？
最佳答案
值仅适用于表单字段元素。您需要改用数据属性:
$(document).on('click', '.open_modal', function() {
var cryptos_id = $(this).data('value');
console.log("cryptos_id: " + cryptos_id)
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a id="coo99" class="open_modal" href="#" data-value="999" data-target="#myModal">Open Modal</a>关于javascript - $(this).val() 不返回值标签的值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48027049/
