JavaScript 实用脚本，很好，珍藏起来[转贴]

如果你找的javascript的东西的话,建议你 ctrl+F? 直接在这个页上找,因为这里80%有你要找的,但是要让你挨着看的话,你就准备看完就去配眼镜!!

//正则匹配
?

匹配中文字符的正则表达式：?[\u4e00-\u9fa5]
匹配双字节字符(包括汉字在内)：[^\x00-\xff]
匹配空行的正则表达式：\n[\s|?]*\r
匹配HTML标记的正则表达式：/<(.*)>.*<\/\1>|<(.*)?\/>/?
匹配首尾空格的正则表达式：(^\s*)|(\s*$)（像vbscript那样的trim函数）
匹配Email地址的正则表达式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配网址URL的正则表达式：http://([\w-]+\.)+[\w-]+(/[\w-?./?%&=]*)?
以下是例子：
利用正则表达式限制网页表单里的文本框输入内容：
用正则表达式限制只能输入中文：onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,'')"?onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\u4E00-\u9FA5]/g,''))"
1.用正则表达式限制只能输入全角字符：?onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,'')"?onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\uFF00-\uFFFF]/g,''))"
2.用正则表达式限制只能输入数字：onkeyup="value=value.replace(/[^\d]/g,'')?"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
3.用正则表达式限制只能输入数字和英文：onkeyup="value=value.replace(/[\W]/g,'')?"onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
