JQuery - 使用脚本在表中获取div ID

问题描述:




hi,

我有带ID的html表,我想知道使用jquery在第一行第一列内的div的id

I have html table with ID and I want to find out id of div inside first row first column using jquery

示例 -

Example -

< table id =" mytable" ; >

<table id="mytable" >

        < tr>< td> < div id =" divtofind" > XYZ< / div>< / td>< / tr>

        <tr ><td> <div id="divtofind" >XYZ</div></td></tr>

        < tr>< td> < div> ABC< / div>< / td>< / tr>

        <tr ><td> <div >ABC</div></td></tr>

< / table>

</table>




我知道桌子和桌子的ID我需要遍历到div才能得到相应div的id,即'divtofind'。

i know id of table & i need to traverse till div to get id of respective div i.e. 'divtofind'.




我是初学者在JQuery中。任何人都可以建议这样做吗?

I am beginner in JQuery. Can anybody suggest way to achive this?




谢谢

.hover(function(){
("div span:first-child") .css("text-decoration", "underline") .hover(function () {


(this).addClass(" sogreen");
},function(){
