Cascading dropdownlist doesn't work properly using jQuery

Asked by raju1 in JScript, PHP Scripting Language

Tags: , ,

Dear Experts,
I am trying to do cascading drop-down-list. When I select division combo, its related district will be populated in district combo. Similarly, when I click district combo, its related than will be populated in thana combo. But it generated following error:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIWebNavigation.loadURI]"  nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS frame :: chrome://global/content/viewSource.js :: viewSource :: line 141"  data: no]
