Select tag and class and get custom attribute

Question

I'm trying to get a custom attribute using jquery and also select it, but i'm having a bit of trouble with it

Here is my jquery code to select the value

var stockId = $("tr .ui-state-highlight").select("[id]").val();

here is the tag i'm trying to select

<tr role="row" id="2" tabindex="0" class="ui-widget-content jqgrow ui-row-ltr ui-state-
highlight" aria-selected="true"><td role="gridcell" style="text-align:left;" 
title="Alkaline Batteries" aria-describedby="productSetsSearchList-data_Name">Alkaline 
Batteries</td><td role="gridcell" style="text-align:left;" title="Alkaline Batteries" 
aria-describedby="productSetsSearchList-data_Title">Alkaline Batteries</td></tr>

Can anyone see what I am doing wrong to select the the tr with class ui-state-highlight and then gather the custom attribute ID

Answer 1

您需要使用组合的选择器tr.ui-state-highlight来找到类ui-state-highlight tr ，然后使用.attr（）获得所需的属性值

var stockId = $("tr.ui-state-highlight").attr("id");

Answer 2

try

var stockId = $("tr.ui-state-highlight").attr("id");

or

var stockId = $("tr.ui-state-highlight").attr("your custom attribute");
