1、数字验证

1.1 整数

/^(-|/+)?/d+$/.test(str)

1.2 大于0的整数（用于传来的ID的验证)

/^/d+$/.test(str)

1.3 负整数的验证

/^-/d+$/.test(str)

2、时间类

2.1 短时间，形如 (13:04:06)

2.2 短日期，形如 (2003-12-05)

2.3 长时间，形如 (2003-12-05 13:04:06)

3、表单类

3.1 所有的表单的值都不能为空

4、字符类

4.1 判断字符全部由a-Z或者是A-Z的字字母组成

4.2 判断字符由字母和数字组成。

4.3 判断字符由字母和数字，下划线,点号组成.且开头的只能是下划线和字母

/^([a-zA-z_]{1})([/w]*)$/g.test(str)

4.4 字符串替换函数.Replace();

5、浏览器类

5.1 判断浏览器的类型 window.navigator.appName 5.2 判断ie的版本 window.navigator.appVersion 5.3 判断客户端的分辨率 window.screen.height; window.screen.width; 6、结合类 6.1 email的判断。 function ismail(mail) { return(new RegExp(/^/w+((-/w+)|(/./w+))*/@[A-Za-z0-9]+((/.|-)[A-Za-z0-9]+)*/.[A-Za-z0-9]+$/).test(mail)); }

6.2 身份证的验证 function isIdCardNo(num) { if (isNaN(num)) {alert("输入的不是数字！"); return false;} var len = num.length, re; if (len == 15) re = new RegExp(/^(/d{6})()?(/d{2})(/d{2})(/d{2})(/d{3})$/); else if (len == 18) re = new RegExp(/^(/d{6})()?(/d{4})(/d{2})(/d{2})(/d{3})(/d)$/); else {alert("输入的数字位数不对！"); return false;} var a = num.match(re); if (a != null) { if (len==15) { var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]); var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } else { var D = new Date(a[3]+"/"+a[4]+"/"+a[5]); var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对！"); return false;} } return true;
