Manipulate array input

senarai · 02-21-2012, 01:55 PM

Hi

I have problem to manipulate my form with array.
I want to copy my input from one input to other input
but it didnt work.

i did explore the usage of document.myForm.feed[3].value
but it gave me error.

Pleaseee help?
Thanks

script sample:
<form name=myForm>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>
<input name=feed[] onBlur=duplicate(this)>

<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
<input name=copier[] onBlur=sendback(this)>
</form>

<SCRIPT>
function duplicate(info)
{
//this function should copy 'info' to copier input
//with the same element location
//eg: feed[3] will copy to copier[3], feed[5] will copy to copier[5]
//(can be any element insert by user)

// the task would be:
// 1. to get which element number has been inserted
// 2. to get the origin text value
// 3. to write the same element position for copier

}

function sendback(info)
{
//this function should copy 'info' to feed input
//with the same element location
//copier[2] will copy to feed[2], copier[3] will copy to feed[3]
//(can be any element insert by user)
}
</SCRIPT>

If you want to copy form value to another form value you could use something like this.

Code:

document.form['formname']['input1name'].value=document.forms['formname']['input2name'].value

Also use CODE tags

thank coldFusion & vwphillips

i copy & paste the whole vwphillips
and it works perfectly..

to simplify the script, i remove the CDATA
..and works!

Hopefully it doesnt create fatal error

again thanks.. :-)
