javascript 兼容（javascript 兼容） Javascripts IE and Firefox (Firefox) compatibility collections 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.
