Javascript help!

[Stoo]

Right peeps, further to this tracking cookies thingy..

They want a unique reference number and amount for every sale, the unique reference isn't a problem, but the tracker will only accept a numerical value for the amount, and our booking pages output the amount in the form "£199.99" as a nice big string..

Our booking pages are almost entirely javascript as well, which is.. umm.. fun..

Anyhoo, will the following strip off the £ character, leaving me with just the number?

<script language="JavaScript">
var str_cost = "[!holiday_cost]";
str_cost = replace(str_cost, "£,");
</script>

Leaving me to input the [!str_cost] into the tracking code?

Stoo have you thought of:

<script>
   //... other code
   var str_cost = "[!holiday_cost]";
   
   str_cost = stripCharacter(str_cost,'£');
   //... and so on


</script>

This should remove every instance of £ from an input string, from memory.

i couldnt get that to work kirkabus

when i do string replacement in JavaScript i use Regular Expressions....

<script language="JavaScript">
    var szSubject = "£89.99"
    var re = new RegExp("£", "g");
    var szResult = szSubject.replace(re, '');
    alert(szResult);
</script>

HTH

aha, after a quick google it's actually a custom built function..

function stripCharacter(words,character) {
//documentation for this script at http://www.shawnolson.net/a/499/
var spaces = words.length;
for(var x = 1; x<spaces; ++x){
words = words.replace(character, "");
}
return words;
}

and it still didn't work..

Using rubbishrubbishrubbishrubbishrubbishey's method..

will report back shortly (cos I'm not very tall )

Bah, must learn to test code before posting. I'd agree with rubbishrubbishrubbishrubbishrubbishey regex is by far more efficient.
