How do I select a specific TR using a unique identifier of a child element/attribute?

in Using jQuery • 9 years ago

I am trying to select the TR (table row) in the following table so I can .hide it. I don't get how to do that since it has no unique attributes compared to the other TR's in the table. Any help greatly appreciated -dave

<html>

<head>

</head>

<body>

<SCRIPT type=text/javascript>SetUploadPageTitle();</SCRIPT>

$(document).ready(function ()

{

$('TR SPAN.ms-formvalidation').hide(); //no can do...this is a unique element text to this TR "<NOBR>Name"

});

</script>

<TBODY>

<TR>

<TD class=ms-formbody vAlign=top><!-- FieldName="Name"

FieldInternalName="FileLeafRef"

FieldType="SPFieldFile"

--><SPAN><SPAN dir=ltr><INPUT id=ctl00_PlaceHolderMain_idDocSetDisplayFormWebPart_ctl00_ctl01_ctl00_ctl00_ctl00_ctl04_ctl00_ctl00_onetidIOFile class=ms-long title=Name name=ctl00$PlaceHolderMain$idDocSetDisplayFormWebPart$ctl00$ctl01$ctl00$ctl00$ctl00$ctl04$ctl00$ctl00$onetidIOFile maxLength=123 size=35 type=text></SPAN><BR></SPAN></TD></TR>

<TR>

<H3 class=ms-standardheader><NOBR>Project Name</NOBR> </H3></TD>

<TD class=ms-formbody vAlign=top><!-- FieldName="Project Name"

FieldInternalName="Project_x0020_Name"

Do you mean this?

$('span.ms-formvalidation').closest('tr').hide();

If I understand your requirement, you want to hide one TR of your table. And the only unique thing you can identify of the TR is that it contains

<NOBR>Name

If that's the case, you can check if the TD contains that string above, if yes, hide the TR. Check out this fiddle:

You can also try the following:

$(function () {
$('td:contains("Name")').has('NOBR').closest('tr').hide();
});

But, it is not exactly the same. This script finds the TD that contains text "Name" and has a <NOBR> node element in it, then find its closest TR and hide it.
