javascript的ie和firefox(火狐)兼容性（Compatibility of JavaScripts IE and Firefox (Firefox)） Compatibility of Javascripts IE and Firefox (Firefox) (2010-04-08, 10:35:58) Reprint Label： Computer Window Firefox IE Document It 1. document.form.item problem (1) existing problems: Many of the existing code statements such as document.formName.item (itemName) cannot run under Firefox (Huo Hu) (2) solutions: Switch to document.formName.elements[elementName (3) other See 2 2. set class object problem (1) existing problems: Many of the collection objects in the existing code are used when they are used (), IE can accept, and Firefox (Huo Hu) cannot.
