身份证号码的验证-javascript脚本

用javascript对身份证号码的验证：

//校验身份证
function checkidCard (idCard) {
    //是否为空  
    if(idCard == '')  
    {  
        alert('请输入身份证号，身份证号不能为空');  
        $("#personQueryCondition.zjhm").focus;  
        return false;  
    }  
    //校验长度，类型  
    if(isIdCardNo(idCard) == false)  
    {  
        alert('您输入的身份证号码不正确，请重新输入');  
        $("#personQueryCondition.zjhm").focus;  
        return false;  
    }  
    //检查省份  
    if(checkProvince(idCard) == false)
