I'm not sure if understood the question.
In order to fill values in textboxes you can set
document.getElementsByName(i + "a").value with the desired value.

For more help, please provide more details.

Use :
intDefects += document.getElementsByName('txtNoofDefects' + i).value;

[intscript]

Use :
intDefects += document.getElementsByName('txtNoofDefects' + i).value;

I got this error

getElementsByName is undefined

THanks

Yes, you are right, I forgot the index:

intDefects += document.getElementsByName('txtNoofDefects' + i)[0].value

Or, you can use getElementById("idvalue").value, in that case you should set the id attribute of the input text control.

Hello i got the same error, when i tried the first one, i got this message underfined2, then entered another number on 2nd input box then it return undefined23 and so no on...

Yes, you are right, I forgot the index:

intDefects += document.getElementsByName('txtNoofDefects' + i)[0].value

You can convert to int using the javascript function:

parseInt(intDefects)

[intscript]

Yes I used parseInt...How can I set the focus to next input box after I've entered the 1st number, just like this

for (i=0; i < 26; i++)
{
if (document.getElementById("txtNoofDefects" + i ).value != '' )

intDefects += parseFloat(document.getElementById("txtNoofDefects " + i ).value);


}

txtTotal.value = intDefects

document.getElementById("txtNoofDefects" + i ).focus()

I got an error on this "document.getElementById("") is null or not an object, please help...Thanks

You can convert to int using the javascript function:

parseInt(intDefects)

Please make sure that the input text haing id = ("txtNoofDefects" + i) exists.
It seems that at the end of the for loop i = 26.

Do you have that input text haing id = "txtNoofDefects26" ?

That should be 25.

[dorinbogdan]

Yes, the last "for" iteration is executed on i = 25, then i becomes 26 and gets out.

Try this test:
[HTML]
<html>
<head>
<script language="JavaScript">
window.onload = function(){
for (i=0;i<26;i++){
window.status = i
}
alert(i);
}
</script>
</head>
<body>
</body>
</html>
[/HTML]

Or, am I missing something?

[acoder]

Yes, the last "for" iteration is executed on i = 25, then i becomes 26 and gets out.

Yes, you're right. Looking at the code, yes, the focus is being given to an element with id "txtNoofDefects26" which probably doesn't exist.

How can I set the focus to next input box after I've entered the 1st number

Depends how you want to do that. Is it after a maximum number of characters are pressed, then you can use this example. Alternatively, you can pass (in this function), an index which you can use instead of i.
