i donno what's happening.....t he value enterd is not being
trimmed.....it leaves the blank spaces as it is in the form.


<SCRIPT language=javasc ript>

function trim(inputStrin g) {
if (typeof inputString != "string") {
return inputString;
}
var retValue = inputString;
var ch = retValue.substr ing(0, 1);
while (ch == " ") {
retValue = retValue.substr ing(1, retValue.length );
ch = retValue.substr ing(0, 1);
}
ch = retValue.substr ing(retValue.le ngth-1, retValue.length );
while (ch == " ") {
retValue = retValue.substr ing(0, retValue.length-1);
ch = retValue.substr ing(retValue.le ngth-1, retValue.length );
}
while (retValue.index Of(" ") != -1) {
retValue = retValue.substr ing(0, retValue.indexO f(" ")) +
retValue.substr ing(retValue.in dexOf(" ") + 1, retValue.length );
}
return retValue;
}

function checkint(txtObj ) {
var retValue;
trim(txtObj);
var numbervalue = txtObj;
for(var i = 0; i < numbervalue.len gth; ++i){
tmptegn = numbervalue.cha rAt(i);
if (tmptegn < "0" || tmptegn > "9"){
if(tmptegn == " ")
i++;
else
{ alert("only numeric value accepted")
txtObj.focus();
txtObj.select() ;
return;
}
}
return true;
}
}



in the form i call it as follows

<td><input type=text name="CategoryN ame" value="<%= CategoryName %>"
maxlength=250 onBlur="trim(th is)"> </td>

<td><input type=text name="CategoryC ode" value="<%= CategoryCode %>"
maxlength=50 OnBlur="checkin t(this)"> </td>

Way too complicated... Try this... It will trim tabs and spaces from
both ends.

function trimLeft(s) { return s.replace(/^[\t ]+/, ""); }
function trimRight(s) { return s.replace(/[\t ]+$/, ""); }
function trim(s) { return trimLeft(trimRi ght(s)); }
