It runs fine and updates all DIVs w/ accurate distances, but the
Browser consistently gives a gdir140.getDistance().html is null or not
an object error on line 38, which is the " document.getElementById
('225').innerHTML=gdir225.getDistance().html;" line in my handleLoad
function.
In the end, this is all to be a hidden function in between when a user
types in an address and sees a list of addresses sorted by distance
(nearest to farthest). My plan is to put the distance data in a
temporary dB table (probably named using the SessionID) and then load
it to the "Results" page from the dB (very, very easy). I know I could
use a client-side array or something like that, but my way will work,
too...I just gotta solve this Javascript error thing first.
Thanks!
i got reply from someone
but not work
You're using the same function for all your directions calls. That
means that results which aren't available every time it's run will
cause it to crash. When the first call returns, the function tries to
use gdir140.getDistance().html whether gdir140.getDistance() can
return anything or not.
At least, that's my guess. A link would enable real debugging. If I'm
right then lines like
if (gdir2.getDistance().html) { document.getElementById
('2').innerHTML=gdir2.getDistance().html; }
should allow the function to work no matter what order the results
returned.
By the way, if you're relying on IE's error messages, line numbers are
always wrong.
