[OpenLayers-Users] Identifier working on Firefox, not IE7?

[Xiaoyu Guan]

Dear All:
I use Geoserver + Tilecache + Openlayers. I have a identifier which only
work on Firefox. but on IE7 , not sure about IE6.

What I did, I have four Layers , two TileCache layers, two Geoserver layers.
I hide two geoserver layers in layerswitcher. People in the map viewer only
can get TileCache layers. I can use WMS getfeatureinfo from Geoserver. the
identifier is base on Geoserver. some poeple told me that IE and Firefox is
different when they reading an array. I have check my script for many times.
but still cannot figure it out. Is there anybody can help me to figure it
out?

Here is some related information about my script
