Using the following code to remove the first leading white space in a form field, can someone give me a clue as to how I can remove more than one space. Thanks
PHP Code:var a = document.form.field
var b = a.value.replace(/^ /,"");
a.value = b;

Re: Javascript help, removing leading white space
You could use compressWhiteSpace to get it down to 1 and then run the above.Originally Posted by CzarJunkie
EDIT:You found it then.

Thanks m8, this does the trick
PHP Code:
var a = document.form.field
var b = a.value.replace(/^\s+|\s+$/g, "");
a.value = b;
Re: Javascript help, removing leading white space
If you wanna strip white space off the front and end my mate supplies this to his customers.
PHP Code:<!-- THREE STEPS TO INSTALL REMOVE_XS_WHITESPACE:
1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document -->
<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function remove_XS_whitespace(item)
{
var tmp = "";
var item_length = item.value.length;
var item_length_minus_1 = item.value.length - 1;
for (index = 0; index < item_length; index++)
{
if (item.value.charAt(index) != ' ')
{
tmp += item.value.charAt(index);
}
else
{
if (tmp.length > 0)
{
if (item.value.charAt(index+1) != ' ' && index != item_length_minus_1)
{
tmp += item.value.charAt(index);
}
}
}
}
item.value = tmp;
}
// End -->
</script>
</HEAD>
<!-- STEP TWO: Insert the onLoad event handler into your BODY tag -->
<BODY onLoad="mystring.select()">
<!-- STEP THREE: Copy this code into the BODY of your HTML document -->
<DIV ALIGN="CENTER">
<B>String to strip excess spaces from:</B>
</DIV>
<DIV ALIGN="CENTER">
<INPUT TYPE="text" NAME="mystring" VALUE=" This is a string " SIZE="50" MAXLENGTH="50">
</DIV><BR>
<DIV ALIGN="CENTER">
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Strip XS Spaces" ONCLICK="remove_XS_whitespace(mystring);mystring.select();return false">
</DIV>
<p>
<DIV ALIGN="CENTER">
Try <A HREF="" ONCLICK="mystring.value=' ';mystring.select();return false;">8 blank spaces</A><BR>
or <A HREF="" ONCLICK="mystring.value=' This is a string ';mystring.select();return false;">try this string</A><BR>
or <A HREF="" ONCLICK="mystring.value=' 1234567890 1234567890 ';mystring.select();return false;">try this string</A>
</DIV>
</BODY>
Re: Javascript help, removing leading white space
I use this:
which then allows you to use things like field.value.trim()PHP Code:String.prototype.trim = function()
{
return this.replace(/(^\s*)|(\s*$)/g, "");
}
