heyyyyyyy i got the solution for this !!(after spending whole
day...........)
in my code, javascript was not accepting the statement :
document.subj_frm.chk_id[i].checked=true
cos in php script i was using :
<input type=checkbox name=chk_id[] value=".$row["subj_id"]."> </td>
i changed the javascript code to :
var max = document.forms[0].elements.length ;
for(i=3; i<=max; i=i+4)
{
document.forms[0].elements[i].checked=true
}
value of "i" initialised to 3 and incremented with 4 as per requirement of
my script. since 3rd, 7th, 11th .... elements are checkbox elements in my
form. its little bit hard coded. but could solve the conflict problem for
php array and javascript.
i got the clue from : http://www.php.net/manual/en/language.types.array.php
thanks to php.net !!!!
