javascript firefox兼容ie的dom方法脚本
人气:0
if(!document.all){
//zzcv的ff ie兼容脚本
/*脚本没有解决的问题及处理:
2.IE下,可以使用()或[]获取集合类对象;Firefox下,只能使用[]获取集合类对象.
解决方法:统一使用[]获取集合类对象.
3.IE下,可以使用获取常规属性的方法来获取自定义属性,也可以使用getAttribute()获取自定义属性;Firefox下,只能使用getAttribute()获取自定义属性.
解决方法:统一通过getAttribute()获取自定义属性.
4.IE下,HTML对象的ID可以作为document的下属对象变量名直接使用;Firefox下则不能.
5.Firefox下,可以使用与HTML对象ID相同的变量名;IE下则不能。
解决方法:使用document.getElementById("idName")代替document.idName.最好不要取HTML对象ID相同的变量名,以减少错误;在声明变量时,一律加上var,以避免歧义.
6.IE下input.type属性为只读;但是Firefox下input.type属性为读写.
8.IE下,可以通过showModalDialog和showModelessDialog打开模态和非模态窗口;Firefox下则不能
9.Firefox的body在body标签没有被浏览器完全读入之前就存在；而IE的body则必须在body标签被浏览器完全读入之后才存在
