How do i display pound sign in Javascript.

**eesyboi** · 02-07-2012, 12:56 PM

I am building an order form that calculates total on select.... But the problem am facing with the javascript i've got is that it displays $ sign but i would like it to display £ sign instead... Here is what the code look like. I would be grateful if someone can show me or help me in changing this.

Code:

function formatCurrency(num) {
  num = num.toString().replace(/\$|\,/g,'');
  if(isNaN(num))
     num = "0";
  sign = (num == (num = Math.abs(num)));
  num = Math.floor(num*100+0.50000000001);
  pence = num%100;
  num = Math.floor(num/100).toString();
  if(pence<10)
      pence = "0" + pence;
  for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
      num = num.substring(0,num.length-(4*i+3)) + ',' + num.substring(num.length-(4*i+3));
  return (((sign)?'':'-') + '$' + num + '.' + pence);
}

Code:

  return (((sign)?'':'-') + '£' + num + '.' + pence);

From your image, it looks like an encoding issue. If I had to guess I'd say that the script is encoded as UTF-8 and that the page is not. Perhaps the page is encoded as ISO-8859-1 or windows-1252.

To tell for sure and to determine a good solution we would need a link to the page.

If you want more help, please post a link to the page on your site that contains the problematic code so we can check it out.

Yes!!!!!!!

it is the encoded thing.. I changed it to UTF-8 in my page header and it worked but i was thinking, if its possible to have two charset and add the encoding UTF-8 to my page and leave what i had there before which is

Code:

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />

can i do something like

Code:

<meta http-equiv="Content-Type" content="text/html; charset='ISO-8859-1,UTF-8';" />

Or would my page work fine with UTF-8?

You can't have two encodings on the same page, no. But almost everything (on your average English language page) that looks OK in ISO-8859-1 will look OK in utf-8. For those few things that don't (if there are any on your page), you can always save your page in utf-8, then they will be fine as well.

Most editors allow you to change from one encoding to another. If yours doesn't, you can use NotePad - load the file in NotePad, choose 'save as', note the encoding dropdown that appears near the bottom right of the Save As dialog box, choose utf-8 and save.
