//1、身份证正则表达式验证  
    function checkIdNo()\{  
       var idno = $("\#idno").val();  
       //15位数身份证验证正则表达式：  
       var isIDCard1=/^\[1-9\]\\d\{7\}((0\\d)|(1\[0-2\]))((\[0|1|2\]\\d)|3\[0-1\])\\d\{3\}$/;  
       //18位数身份证验证正则表达式 ：  
       var isIDCard2=/^\[1-9\]\\d\{5\}\[1-9\]\\d\{3\}((0\\d)|(1\[0-2\]))((\[0|1|2\]\\d)|3\[0-1\])\\d\{3\}(\[0-9\]|X)$/;  
    if(!(isIDCard1.test(idno)||isIDCard2.test(idno)))\{
