validate form text boxes

[ibjdt]

i have a data table containing sometimes hundreds of rows - each with it's own 'edit' link.
the link contains an onclick call to javascript to show a div in the next table row.

function make(item){ 
		document.getElementById(theDIV).innerHTML = '<form name=invEdit'+item+' onSubmit="return checkInvEdit('+item+');"><input name=VartoChange....>';
}

the div form allows data update, but i can't allow a 0 value so i tried to check the form like this

function checkInvEdit(item){ 
alert(item);
	var VartoChange = document.invEdit['item'].VartoChange.value;
	if (VartoChange == "" || VartoChange == "0") { alert ('\n- Please enter a non-zero value'); return false; }
}

the alert is a test and it works - passes the correct item number - but not the rest.

document.invEdit.item is null or not an object

i don't want to loop through all the elements to determine which was submitted because there can be hundreds and it would take too long.

thanks.

Your first piece of code, creates a form who's name is composed of the string "invEdit" and a whatever is in the "item" variable.

Assuming its a number say 5 you'd get invEdit5, but that does not make the name an array.

Assuming in your second piece of code "item" is still a number then: invEdit[item] would really be requesting the element 5 in the invEdit array, however there is no invEdit array, because all your forms have a different name.

Instead what you want is to access a form who's name is "invEdit" plus a number so:

document.forms['invEdit'+item].VartoChange.value;
