I need to create more than one text box with the same name(this call array),with the code; for i = 1 to CInt(request.Form("quantity")) count = count + 1 serial_field = "serial"&count end loop then, when I need to check whether user already fill in this text box, I can not access that text box name.Text box name suppose to be serial1, serial2 and so on.I am using this code; for (a=o;a<=30;a++){ if (document.Reg.element.serial[a].value == "") { err = true; msgstring = "Fill in serial number"; } } I can access the value only if I directly use the name like; if (document.Reg.element.serial1.value == "") { err = true; msgstring = "Fill in serial number"; } Any suggestion what I should do to solve this problem. I am sorry my explanation is quite massy. Thanks

serial_field = "serial"&count gives all the fields different names - serial1, serial2 etc... Just use serial_field = "serial";

Ya, that true according to logic but the problem bow, the object(text box) has been created first than we need to check when user click on save button. How we can refer to the object name?

[Ryan Binns]

I'm not a javascript expert, but you should be able to use

document.all.serial[0].value
document.all.serial[1].value
etc...

Hope this helps,

Try this: (Note: Change the 6 in the first "for loop" with your total number of textboxes.) function fnCheck() { var strTextBoxName; for(var i=1;i<6;i++) { strTextBoxName = "serial" + i; for(var j=0;j

This would work if the fields all have the same name (serial in this example). But here the fields include an increasing number so he needs to use: for(var i = x; i < y; i++) { document.formName["serial" + i]; } where x is the number of the first field and y is the number of the last.

Yeah I know, hence my first reply :)

What about after creating serial1, serial2, etc, using function foo(bar) { eval('serial'+bar+'.value = ...'); } HTH Paul ;)
