changing and hiding parts of a table

I've got a html table with td class-formlabel and text (HP)Hello

1. Why doesn't this replace the text?

   $(this).text().replace('(HP)','');
   

2. Why does this remove formating if this is $("td.ms-formlabel").each(function(){

   $(this).text("hello");
   

3. How can hide the TR ro开发者_如何学运维ws for a match given the rendered html above and the below code? (Note I need to use the below condition and loop)

   $("td.ms-formlabel").each(function(){
   
   if($(this).text().match('(HP)')){
      // what code here to hide the entire TR row ?
   }
   

Thanks.

1. $(this).text().replace('(HP)',''); does replace the text, but you don't do anything with it - try:

   var text = $(this).text().replace('(HP)','');
   $(this).text(text);
   

2. It shouldn't remove and formatting unless you're applying it with tags inside.ms-formlabel

   <td class="ms-formlabel"><b>Bold</b></td>
   

   will become

   <td class="ms-formlabel">Hello</td>
   

3. You can use:

   $(this).closest('tr').hide();
   

1. .text() returns a string. To modify and replace the text, you have to set it back again. It's kind of the equivalent to the fact that x + 5 doesn't change x. You have to type x = x + 5 In this case, the code would be this:

   $(this).text($(this).text().replace('(HP)',''));
   

2. I don't quite understand this question. If you're trying to set some HTML styling, use the .html() function instead.

3. Try this:

   if ($(this).text().match('(HP)')) {
       $(this).closest('tr').hide();
   }
   

A couple of things:

• You should use :contains
• Text will strip formatting, you should use .html()
• To specify HTML (or text for that matter), you put the new content within the brackets, i.e. element.text(content)

So here is an example...

$("td.ms-formlabel:contains('(HP')").each(function(){
    var $this = $(this);
    $this.html($this.html().replace('(HP)',''));
    $this.closest('tr').hide();
}

I think that's what you want. The only thing that I might be wrong with is which row you want to hide... your wording is kind of confusing...
