Finding multiple characters and replacing with JQuery

Question

I have the following JQuery AJAX call that sends HTML form data to my server side script to deal with. However I currently find line breaks and convert them to <br /> for display in another part of my application. I now need to make sure I am stripping out apostrophes however I am not confident on how to replace multiple characters in one go.

This is the JQuery I use currently before adding this into my AJAX.

description = $("#description").val().replace(/\n/g, '<br />');

Can anyone point me in the right direction?

Thanks

You don't have to do it in one go in the sense of one call to .replace(), just chain multiple .replace() calls:

description = $("#description").val().replace(/\n/g, '<br />')
                                     .replace(/'/g, '');

(Or replace with ''' or ''' if that's what you need...)

I agree with nnnnnn that you don't have to do it all in one go though you can use the or | regex operator and use a callback like below, see mdn regex for more details

var foo = '"there are only 10 people in this world that understand binary, 
            \n those who can and those who can\'t"\n some joke';

foo = foo.replace(/\n|"/g, function(str) {
  if (str == '\n') {
    return '<br/>';
  } else {
    return '';
  }
});

document.write(foo);

here is a demo

You can use | (pipe) to include multiple characters to replace:

str = str.replace(/X|x/g, '');
