Here's my version of a trim function as well as a few others ;)
I would put the "trimSpaces" function in an includes .js file and call it in
your pages using:
function validate()
{
// strips leading and trailing spaces
for (i=0; i < document.form.elements.length; i++)
{
document.form.elements[i].value = trimSpaces(document.form.elements[i].value);
}
// Now do field validation
}
// This function is for stripping leading and trailing spaces
function trimSpaces(str)
{
if (str != null)
{
var i;
for (i=0; i < str.length; i++)
{
if (str.charAt(i)!=" ")
{
str=str.substring(i,str.length);
break;
}
}
for (i = str.length-1; i >= 0; i--)
{
if (str.charAt(i)!=" ")
{
str = str.substring(0,i+1);
break;
}
}
if (str.charAt(0)==" ")
{
return "";
}
else
{
return str;
}
}
}
Hope this helps!
