我在dom中看到一个属性 <td> 元素，但无法在jQuery中检索到

Question

I am trying to get the value width="25%" from <td valign="top" width="25%"> , I am starting from a descendant location way below the <td> . Possibly there might be more <td> elements between my target <td valign="top" width="25%"> . But I simply cannot get 25% from the below.

I have tried:

var prts = jQuery('.someClassWayBelow').parents('td');

jQuery.each (prts, function () { var css = prts.width(); console.log(css)});
jQuery.each (prts, function () { var css = prts.attr("width"); console.log(css)})

I get 664px or 664 or undefined , how do I get a return of 25% ?

Appreciate in advance.

Answer 1

 $(document).ready(function(){console.log($("div").attr('width')); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div width="25%"> </div>

使用$ (this)将要考虑的元素制成jQuery对象后，便可以访问attr()方法
