Question

I m 试图从我的亲人那里获得身份证

<div id="btn1"><label class="btn"><input type="submit" value="Submit"/></label></div>
<div id="btn2"><label class="btn"><input type="button" value="Add"/></label></div>

页: 1 学历:

$( .btn ).each(function () {
    alert($( .btn ).parent().attr("id"));
});

该功能将价值折合1两次。它应当归还btn1, btn2。

提前感谢。

Answer 1

您再次在座右边使用<代码>.btn的选任人。改动是指使用<条码>的现值。

$( .btn ).each(function () {
    alert($(this).parent().attr("id"));
});

there really is no reason to use three jQuery function calls here. jQuery should be used only when it does the job better.

And a reference for some of these common scenarios: https://stackoverflow.com/a/4652402/803739
