//過濾數字

//正則匹配
匹配中文字符的正則表達式： [\u4e00-\u9fa5]
匹配雙字節字符(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里的文本框輸入內容：
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,''))"
