Question

I have a string that and I am trying to extract the characters before the quote.

Example is extract the 14 from 14′ – €14.99

I am using the follwing code to acheive this.

$menuItem.text().match(/[^']*/)[0]

My problem is that if the string is something like €0.88 I wish to get an empty string returned. However I get back the full string of €0.88.

What I am I doing wrong with the match?

This is the what you should use to split:

string.slice(0, string.indexOf("'"));

And then to handle your non existant value edge case:

function split(str) {
 var i = str.indexOf("'");

 if(i > 0)
  return  str.slice(0, i);
 else
  return "";     
}
