//正則匹配

匹配中文字元的正則表達式： [\u4e00-\u9fa5]
匹配雙字元字元(包括漢字在內)：[^\x00-\xff]
匹配空行的正則表達式：\n[\s| ]*\r
匹配HTML標記的正則表達式：/<(.*)>.*<\/\1>|<(.*) \/>/
匹配首尾空格的正則表達式：(^\s*)|(\s*$)（像vbscript那樣的trim函數）
匹配Email地址的正則表達式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配網址URL的正則表達式：http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?
以下是例子：
利用正則表達式限制網頁表單裡的文字框輸入內容：
用正則表達式限制只能輸入中文：onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,'''')" onbeforepaste="clipboardData.setData(''text'',clipboardData.getData(''text'').replace(/[^\u4E00-\u9FA5]/g,''''))"
1. 用正則表達式限制只能輸入全角字元： onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,'''')" onbeforepaste="clipboardData.setData(''text'',clipboardData.getData(''text'').replace(/[^\uFF00-\uFFFF]/g,''''))"
2. 用正則表達式限制只能輸入數字：onkeyup="value=value.replace(/[^\d]/g,'''') "onbeforepaste="clipboardData.setData(''text'',clipboardData.getData(''text'').replace(/[^\d]/g,''''))"
3. 用正則表達式限制只能輸入數字和英文：onkeyup="value=value.replace(/[\W]/g,'''') "onbeforepaste="clipboardData.setData(''text'',clipboardData.getData(''text'').replace(/[^\d]/g,''''))"
