偶又来发原创了呵呵....秉承俺的一贯风格,依然是IE Only
说明:用来查看DOM的工具,可以当作手册来用,也可以用来Debug,很方便的说
把代码copy到要调试的页面中,浏览时点击DOM Tester链接就会打开DOM查看,双击展开对象,右边的文本框里显示的是属性值,修改文本框会改变对应的属性,用来调试配色什么的还是满方便的说....呵呵
其实代码本身没什么技术含量,核心就是用 for in 语句来取对象的属性而已,要说有什么亮点.....嗯......不知道窗口间的函数调用算不算......
-+-+-+-+-+-+-+-+-+-+偶是传说中的无敌分割线-+-+-+-+-+-+-+-+-+-+
1/21更新
俺这两天在研究兼容性,所以就把代码重写了下,现在支持IE5.0+ & FF 1.5.01
用这个可以明显看出FF与IE的不同,呵呵
