javascript - How to handle repeated binding events?

The unbinding pop-up window is public. When I click confirm and cancel, how do I know that the corresponding bank card click is the unbinding (corresponding bank card dom removal) operation

<code><!-- 银行卡列表 -->
    <div class="bankcard-block">
        <div class="bankcard-item">
            <img class="card-img" src="<{$style}>statics/images/yinlianzhifuicon.png">

<code>用 jquery 的 方式
$('.ubind-card').click(function(){
    //的到当前银行卡列表的下标
    var ubindIndex = $(this).parents('.bankcard-block').index();
    //给确定按钮赋一个标识
    $('.unbind-sure').attr('val',ubindIndex ).show();
});
$('.unbind-sure').click(function(){
    var index = $(this).attr('val');
    $('.bankcard-block:eq('+index+')').remove();
});
</code>

If possible, I hope you will adopt it
It’s very simple. When the user clicks to unbind, you can bind the information of which bank card the user clicked to the properties of the pop-up box label. For example, you can bind the bank card serial number to it, like this

. When the user clicks to confirm, you can just go to the top to get it.

Get the

DOMJavaScript event object

through

event.target

or event.currentTarget Use a variable to save the currently operated card. <pre class="brush:php;toolbar:false">&lt;code class=&quot;javascript&quot;&gt;var currentCart = -1;//默认-1 $('#cards').on('click','.btnJieBang',function(){ currentCart=this.dataset.cartid; }); //弹窗确定的事件里，去读取currentCart变量即可&lt;/code&gt;</pre>
When you click Unbind, you can get its parent element, and then delete the parent element through related operations to achieve the goal.

Add a distinguishable data-id after unbinding

Bind a unique identifier
