Hi,
I've included a leftTrim() function below that works. Unfortunately a
texbox
filled with spaces still has a length. So the spaceTrim() function below
is
what you really need. Compliments of the JavaScript SourceBook by Gordon
McComb.
function leftTrim (InString) {
OutString=InString;
for (Count=0; Count < InString.length; Count++) {
TempChar=InString.substring (Count, Count+1);
if (TempChar!=" ") {
OutString=InString.substring (Count, InString.length)
break;
}
}
return (OutString);
}
function spaceTrim(InString) {
var LoopCtrl=true;
while (LoopCtrl) {
if (InString.indexOf(" ") != -1) {
Temp = InString.substring(0, InString.indexOf(" "))
InString = Temp + InString.substring(InString.indexOf(" ")+1,
InString.length)
} else
LoopCtrl = false;
}
if (InString.substring(0, 1) == " ")
InString = InString.substring(1, InString.length)
if (InString.substring (InString.length-1) == " ")
InString = InString.substring(0, InString.length-1)
return (InString)
}
