How to avoid JS Error in the status bar when report doesnt contain value.

Question

Hi
Whenever the tabular report doesnt show any records for the given input parameter (parameter passed using select list item).
We are displaying error message in APex. But at the status bar, it is showing "Error" (unspecified
error).
Kindly let me know how to avoid this kind of error at status bar.
Thanks
Vijay

Hi Vijay,
Your javascript is probably trying to access one or more of the items within a displayed tabular form - the "f01", "f02" etc named items.
If your script does something like:
var x = document.getElementsByName("f01");
..rest of your code for f01 items..you can test if there are any "f01" items by doing:
var x = document.getElementsByName("f01");
if (x){
..rest of your code for f01 items..
}If there are no items, x is null, so the "..rest of your.." script will not get executed and no errors will occur.
