remove <b> tag from a table with a class
in Using jQuery
•

Hi guys,
I now know how to write remove statment if its to remove one piece of html such as a <hr/>
However in this case I'm trying to write a bit of javascript to remove a <b>TEXT</b> with whatever text inside. And in this case it's only for a line of text that apears in a <td> which has a class:
This is the html:

Thanks for that Jay, that works well.
However each page will contain different text in this table so I only want it to remove the text in this specific table which apears on every page wit the class="column_main" which contains a <b>

Then you can go with $('.column_main').find('b').remove();

Thanks for that, that works really well.
I'm tring to get rid of the spaces after the <b> but it doesn't seem to be working.
This is the html again:

- $('.column_main').find('b').remove();
$('td').remove(":contains( )");

Is there anything else in that cell? If not it might be easier just to set its HTML
$('.column_main').html(')'
$('.column_main').html(')'

Unfortunately the developers creating our site decided to use the same class all over the page. so it really needs to be specific to a <td> and specific to it containing two spaces after the <b></b> nbsp;
It's really annoying but they are the only distinguishing features on that section.

$('td.column_main').html(''); will select table cells with the class column_main and set the HTML to be blank. The problem with is that it has already been converted to a space by the time it gets to browser output. If you want to get that you may have to use some regex.

Thanks for this:
could it not be something like:
$('td.column_main contains('<b>NEW IN</b> ')').html('');
?? or something similar because I don't think that works?

maybe something like this?
$('td.column_main b:contains("NEW IN")').empty();if there are other things in that cell, its going to get a little complicated, we'll have to loop through the text nodes using .contents() and then .filter() to filter to only text nodes, then for each text node see if it consists of two spaces, and if it does, remove the two spaces without removing anything else.

The has already been interpreted by the browser as a space - you cannot select it.

Ah ok fair enough.
I'm not sure why the developers of our system decided to replicate the same classes throughout the same section. It makes it so much more difficult.

i don't think that would work. But, this would:

- $('td.column_main b:contains("NEW IN")').parent().empty();

Ah that works but in the section I want to choose it gets rid of the image within there also.
http://jsfiddle.net/HKsdS/3/
Instead of .empty() can I put in .replaceWith(' ');
and add the html for an img in the (' ') ?

or so:
- $(''td.column_main').has('b').filter(":contains(' ')").empty();
Re: Re: remove <b> tag from a table with a class

it isn't a normal space, its a which can't be selected in that way, and the td contains other elements that don't need to be removed

hmm... try this instead, so you dont have to modify this if you have to change the image later:
$('td.column_main:contains("NEW IN")').contents().each(function(){
var re = new RegExp(String.fromCharCode(160) + String.fromCharCode(160));
if ( re.test($(this).text()) || $(this).is('b:contains("NEW IN")') )
$(this).remove();
});
var re = new RegExp(String.fromCharCode(160) + String.fromCharCode(160));
if ( re.test($(this).text()) || $(this).is('b:contains("NEW IN")') )
$(this).remove();
});
it removes the <b> and any " " that it finds.

Hi again,
does anyone know a way of replacing a selected piece of html and replacing it with something I re write?
