Trim Function Results

Question

I have a function that returns values from a database. My issue: the function adds "" on the return values. I need to trim the values before displaying them on the user's screen.

This is my function

 <script language="JavaScript" type="text/javascript">
    function handleProcedureChange(procedureid)
    {
        procedureid= document.form1.procedure.value;
        //alert(procedureid);
        var url ="some URL goes here"; 
        url=url+"ProcedureID="+procedureid;

        $.get(url, function(procedureResult) {
            $("#procedureDescription").text(procedureResult);
        });
    }
   </script>

The prcedureResult is the value being returned and the one I need to trim from the quotes before displaying it.

Fix the problem at the root - dont mess around removing the quotes in JavaScript — Manse, May 15 '12 at 16:12
I don't see you useing any trim function, so what problem are you having with it? — Felix Kling, May 15 '12 at 16:12

Use this to remove quotes :

$.get(url, function(procedureResult) {
     procedureResult = procedureResult.replace(/^"+|"+$/g, "");
     $("#procedureDescription").text(procedureResult);
});

This replaces " from the start (^) and end ($) of the string with nothing ("")

What's `replaceAll`? Shouldn't that be `procedureResult.replace(/^"|"$/g, "");`? – gen_Eric May 15 '12 at 16:17

A string in javascript doesn't have a `replaceAll` method – JaredPar May 15 '12 at 16:17
@JaredPar ta .. must have been day-dreaming ! – Manse May 15 '12 at 16:18

I don't believe the updated version will work either. You're specifying a regex as a string literal and hence it won't be interpreted as a regex. – JaredPar May 15 '12 at 16:19

@ManseUK: It's still not right. It needs it be a regex, you can use the regex literal: `.replace(/^"+|"+$/g, "")` (note the `+`, so it matches all `"`). – gen_Eric May 15 '12 at 16:19

@Crematorio: You're welcome, but give this answer the credit, I just helped fix it up :-P – gen_Eric May 15 '12 at 16:26

Try the following function which will strip off all leading and trailing quotes from a string value

function stripQuotes(str) {
  str = str.replace(/^\"*/, '');
  str = str.replace(/\"*$/, '');
  return str;
}

It can be used as so

$.get(url, function(procedureResult) {
  procedureResult = stripQuotes(procedureResult);
  $("#procedureDescription").text(procedureResult);
});
