how to remove and using javascript or jQuery?

Question

I have written the following code. But it is removing only   not


var docDesc = docDescription.replace(/(&nb         


        

Answer 1

Try this

var text = docDescription.replace(/(?:&nbsp;|<br>)/g,'');

Answer 2

Try "\n"...see if it works.

Answer 3

You can achieve removing <br> with CSS alone:

#some_element br {
  display: none;
}

If that doesn't fit your needs, and you want to really delete each <br>, it depends, if docDescription is really a string (then one of the above solutions should work, notably Matt Blaine's) or a DOM node. In the latter case, you have to loop through the br elements:

//jquery method:
$('br').remove();

// plain JS:
var brs = common_parent_element.getElementsByTagName('br');
while (brs.length) {
  brs[0].parentNode.removeChild(brs[0]);
}

Edit: Why Matt Baline's suggestion? Because he also handles the case, where the <br> appears in an XHTML context with closing slash. However, more complete would be this:

/<br[^>]*>/

Answer 4

This will depend on the input text but I've just checked that this works:

var result = 'foo <br> bar'.replace(/(<br>)*/g, '');
alert(result);

Answer 5

Try:

var docDesc = docDescription.replace(/[&]nbsp[;]/gi," "); // removes all occurrences of  
docDesc = docDesc.replace(/[<]br[^>]*[>]/gi,"");  // removes all <br>

Answer 6

You can do it like this:

var cell = document.getElementsByTagName('br');
var length = cell.length;
for(var i = 0; i < length; i++) {
    cell[0].parentNode.removeChild(cell[0]);
}

It works like a charm. No need for jQuery.
