写js取url，加入参数

[zwwz3590]

如：http://www.sina.com/sddd/或者http://www.sina.com/sddd/aa/

改为：http://www.sina.com/big/sddd/
http://www.sina.com/big/sddd/aa/


在.com结束后面加上/big/下面路径

[myvicy]

<script>
str = "http://www.sina.com/sddd/";
//字符串直接替换
newstr = str.replace('.com/','.com/big/');
alert(newstr);
//正则替换
newstr = str.replace(/(.+?\/\/.+?)(\/.+)/,'$1/big$2');
alert(newstr);
</script>
