1、身份证验证（带x）
//验证身份证信息（获取出生日期和性别）
function func_CheckSFZ(ob)
{
var obj = ob.value;
obj = obj.toUpperCase();
if (!(/(^\d{15}$)|(^\d{17}([0-9]|X)$)/.test(obj)))
{
alert('输入的身份证号长度不对，或者号码不符合规定！\n15位号码应全为数字，18位号码末位可以为数字或X。');
return false;
}
var gre = /^(\d{6})(\d{2})([01]\d)([0123]\d)(\d{3})$/;
var reg = /^(\d{6})(18|19|20)?(\d{2})([01]\d)([0123]\d)(\d{3})([0-9]|X)$/;
var csny = document.getElementById("txt_CSRQ").value;
var XB = document.getElementById("sel_XB").value;
if(obj.value != "")
{
if(obj.length == 15 || obj.length == 18)
{
if(obj.length == 15)
{
if(gre.test(obj))
{
var year = obj.charAt(6)+obj.charAt(7);
if(parseInt(year) < 10)
{
year = "20"+ year;
}
else
{
year = "19"+ year;
}
var month = obj.substring(8,10);
var day = obj.substring(10,12);
csny = year+"-"+month+"-"+day;
if(parseInt(obj.charAt(14)/2)*2 != obj.charAt(14))
XB ="男";
else
XB = "女";
}
else
{
alert("提示：身份证格式不正确！");
return false;
}
}
else if(obj.length == 18)
{
if(reg.test(obj))
{
var year = obj.substring(6,10);
var month = obj.substring(10,12);
var day = obj.substring(12,14);
csny = year+"-"+month+"-"+day;
if(parseInt(obj.charAt(16)/2)*2 != obj.charAt(16))
XB ="男";
else
XB = "女";
}
else
{
alert("提示：身份证格式不正确！");
return false;
}
}
document.getElementById("txt_CSRQ").value = csny;
document.getElementById("sel_XB").value = XB;
}
else
{
alert("提示：身份证为15位或者18位！");
return false;
}
}
return true;
}
2、验证金额：
/^-?((\d{1,3}(,\d{3})*?)|\d+)(\.\d{1,2})?$/
