//正則匹配

匹配中文字符的正則表達(dá)式： [\u4e00-\u9fa5]
匹配雙字節(jié)字符(包括漢字在內(nèi))：[^\x00-\xff]
匹配空行的正則表達(dá)式：\n[\s| ]*\r
匹配HTML標(biāo)記的正則表達(dá)式：/< (.*)>.*<\/\1>|<(.*) \/>/
匹配首尾空格的正則表達(dá)式：(^\s*)|(\s*$)（像vbscript那樣的trim函數(shù)）
匹配Email地址的正則表達(dá)式：\w+([-+.] \w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配網(wǎng)址URL的正則表達(dá)式：http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?
以下是例子：
利用正則表達(dá)式限制網(wǎng)頁表單里的文本框輸入內(nèi)容：
用正則表達(dá)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(dá)式限制只能輸入全角字符： onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\uFF00- \uFFFF]/g,''))"
2.用正則表達(dá)式限制只能輸入數(shù)字：onkeyup="value=value.replace(/[^\d]/g,'') "onbeforepaste="clipboardData.setData ('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
3.用正則表達(dá)式限制只能輸入數(shù)字和英文：onkeyup="value=value.replace(/[\W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
