May 28.2004

hi
I am validating a form which has a table with rows added to it dynamically when the user clicks the “Add Row” button. all of the fields have the same name plus a number which is the number of the row which they are added in.this is a part of my function.

for(i=1; i< num_of_rows_in_my_table ; i++)
{
if (document.myform.[COLOR=blue]myselect+i[/COLOR].value==0)
{ //show error }
………
}
my problem is that I dont know what to use instead of myselect+i to make it working.

can anyone help me with this

@TageMay 30.2004 — Maybe something like this?[code=php]for(i=1; i<= num_of_rows_in_my_table ; i++)
{
if (document.myform.elements["myselect"+i].value=="")
{ //show error }
.........
}[/code]I added an equal sign after the less than operator, so if it doesn't work properly, take that out. And changed 0 to "" because I thought you were trying to check if the element was empty. x.x
