今天在获取select中的option元素,然后通过正则表达式把option字符转换成li字符时,在chrome FF opera中能成功,在IE下还是option字符.

用alert()弹出框打印出来一看,打印出来的HTML元素标签名都是大写的。


原来是这么写的:

optionsUI = optionsUI.replace(/(option)/g,"li");


修改后这么写的:

optionsUI = optionsUI.replace(/(option)/gi,"li");

开始没有考虑到在IE下获取的HTML标签名是大写的。所以没有加在 i 。


附上一张有关regexp修饰符



IE效果标签名是大写:



chrome效果标签名是小写的:
