how do I select a character in a parent id to use as a variable value in another selector based statement?

in Using jQuery • 9 years ago

I would like to copy the integer (in this case the number "7") in the id within the string id="WebPartWPQ7" that is within the following structure of html. The element and strings in "<b class="ms-standardheader">Project
Name</b> are always present. What value of selector would allow to capture the "7" and use it as a value in a variable. Any help would be greatly appreciated. tx dave:

<h2>Blattman-E3 Ikke</h2>

<tbody>

<tr>

<td valign="top" nowrap=""><b class="ms-standardheader">Project

Name</b></td>

</td><td valign="top">E3 inihibition of IKKe signaling. </td>

</tr><tr>

</td><...

It's not clear where you want to copy the value to, nor when you want to do this copy. Anyway, something like this:

$('div[id^="WebPart"]').each(function() {
var intId = this.id.replace(/.*(\d+)/, '$1'); // Extract numeric part
$('b.ms-standardheader', this).append(intId);
});

Amazing. Thanks.

I am trying to replace put the initID value into the the following string to replace the character "5" in the following statement.

if (_ProjectNumbers.indexOf($("#WebPartWPQ5 tr:eq(3)>td:eq(2)").text()) !=-1)

I tried creating a variable

var wpq = "($("#WebPartWPQ"+initId+" tr:eq(3)>td:eq(2)").text()) !=-1)";

so I could replace the original statement with

if (_ProjectNumbers.indexOf+wpq

but no dice.

Essentially the goal is to open the page, get the number and use it in another statement on the same page. Any guidance appreciated and thanks for the original response. I will study it's logic but kind of new to this level of complexity. -dave

Just add the variable into the string selector. Like this:

if (_ProjectNumbers.indexOf($('#WebPartWPQ' + intId + ' tr:eq(3)>td:eq(2)').text()) !=-1)
