(1)应用：计算字符串的长度（一个双字节字符长度计2，ASCII字符计1）&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; String.prototype.len=function(){return this.replace([^/x00-/xff]/g,"aa").length;} (2)应用：javascript中没有像vbscript那样的trim函数，我们就可以利用这个表达式来实现 &nbsp;&nbsp; String.prototype.trim = function() &nbsp;&nbsp; { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return this.replace(/(^/s*)|(/s*$)/g, ""); &nbsp;&nbsp; } (3)应用：利用正则表达式分解和转换IP地址 &nbsp;&nbsp; function IP2V(ip) //IP地址转换成对应数值 &nbsp;&nbsp; { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; re=/(/d+)/.(/d+)/.(/d+)/.(/d+)/g //匹配IP地址的正则表达式 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if(re.test(ip)) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return RegExp.$1*Math.pow(255,3))+RegExp.$2*Math.pow(255,2))+RegExp.$3*255+RegExp.$4*1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; } &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; else &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; throw new Error("Not a valid IP address!") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; } &nbsp;&nbsp; } (4)应用：从URL地址中提取文件名的javascript程序 &nbsp;&nbsp; s="http://www.9499.net/page1.htm"; &nbsp;&nbsp; s=s.replace(/(.*//){0,}([^/.]+).*/ig,"$2") ; //Page1.htm (5)应用：利用正则表达式限制网页表单里的文本框输入内容 &nbsp;&nbsp; 用正则表达式限制只能输入中文：οnkeyup="value=value.replace(/[^/u4E00-/u9FA5]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/u4E00-/u9FA5]/g,''))" &nbsp;&nbsp; 用正则表达式限制只能输入全角字符： οnkeyup="value=value.replace(/[^/uFF00-/uFFFF]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/uFF00-/uFFFF]/g,''))" &nbsp;&nbsp; 用正则表达式限制只能输入数字：οnkeyup="value=value.replace(/[^/d]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/d]/g,''))" &nbsp;&nbsp; 用正则表达式限制只能输入数字和英文：οnkeyup="value=value.replace(/[/W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^/d]/g,''))" <a style="COLOR: blue; TEXT-DECORATION: none" rel="nofollow">&lt;返回&gt;</a> <a rel="nofollow">30.弹出来提示对话框</a> window.showModalDialog(url);
