traversing form elements

[xylex_blaiste]

help with doing this on javascript please.

i have a form where there are many rows. each row has 15 columns. i would only like the values of the columns from 9 to 12. on these columns, a checkbox is there where a user can un/check it. checked being 1 and unchecked 0.

how do i go about this?

by the way i have to traverse the elements of checkboxes on all columns first and see if it is checked or not before i submit.. .

What do you mean ? Do you want something which on the fly traverses itself ?
Where your part of the checkform, as it is beeing filled with check a seperate similar area, where the traverse pattern will emerge ?
Something like:

Orriginal form:
010010010110010
001010010100101

Traverse form:
001010010100101
010010010110010

Or is it something completely different ? Where, once you press submit the form itself will emerge traversed ?

Or are you looking for something like this: http://rieee.dk/check/
Then you can follow this thread and if you're currious on how the data is beeing parsed on, you can check this thread

yeah something like that. but it will only traverse after submit was clicked.

i got it to work like this.

    var the_form = document.getElementById("form1");
    var str = "";
    for ( var x=0; x<the_form.length; x++ ) {
    	temp = the_form.elements[x].name
	if(temp=="col9"||temp=="col10"||temp=="col11"||temp=="col12"){		
		str+=conv(the_form.elements[x].checked);
	}

so the output is many zeroes and ones. the names of the checkboxes depends on which column it belongs to. so if its at column 8 then it is named col8. that's why at first i was having a difficult time coz i was used to calling elements by unique names or IDs and this was something new to me.

i learned a different trick some time ago about putting '[ and '] after an element name so i could just easily get the values using a loop. couldn't apply it in this case though.

would it be a good idea to pass this with a POST method or GET? what do you advise? now that one problem is solved, another comes up. LOLz

i'll read those links in a while.. .
