jquery.validate.js 应用例子
验证表单是我们经常需要做的，今天发现了jQuery一个很强大的验证表单插件(jquery.validate.js 下载地址：http://bassistance.de/jquery-plugins/jquery-plugin-validation/)，研究了一下发现他不光强大而且十分易于上手。真是不用不知道，一种真奇妙啊！
下面附上我写的一个小例子：
jquery.validate.js
<script>
function checkidcard(num){
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("请输入15或18位身份证号,您输入的是 "+len+ "位");
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;
}
</script>
<script type="text/javascript">
$.validator.setDefaults({
submitHandler: function() { alert("submitted!"); }
});
// 添加验证方法 (身份证号码验证)
jQuery.validator.addMethod("isIdCardNo", function(value, element) {
return this.optional(element) || checkidcard(value);
}, "请正确输入您的身份证号码");
$().ready(function() {
$("#firstform").validate();
$("#secondform").validate({
/*errorLabelContainer: "#messageBox", //显示错误信息的容器ID
wrapper: "li", //包含每个错误信息的容器*/
rules:{
xm:{
required: true,
minlength: 2,
maxlength: 5
},
pwd:{
required: true,
minlength: 6
},
confirm_pwd:{
required: true,
equalTo: "#pwd"
},
f2csrq:{
required: true,
date: true
},
f2xjzd: {
required: true
},
f2sfzh:{
/*digits: true,
rangelength: [18,20]*/
required: true,
isIdCardNo: true
}
},
messages:{
xm:{
required: "请填写姓名",
minlength: "字符长度不能小于2个字符",
maxlength: "字符长度不能大于5个字符"
},
pwd:{
required: "请填写密码",
minlength: "字符长度不能小于6个字符"
},
confirm_pwd:{
required: "请再次输入密码",
equalTo: "密码不一致"
},
f2csrq:{
required: "请输入出生日期",
date: "日期格式不正确(例：2009/04/07)"
},
f2xjzd:{
required: "请输入地址"
},
f2sfzh:{
/*digits: "身份证号码只能为数字",
rangelength: "身份号码长度为18～20个字符"*/
required: "请输入身份证号",
isIdCardNo: "身份证号不正确"
}
}
});
/*// 输入框获得焦点时，样式设置
$('input').focus(function(){
if($(this).is(":text") || $(this).is(":password"))
$(this).addClass('focus');
if ($(this).hasClass('have_tooltip')) {
$(this).parent().parent().removeClass('field_normal').addClass('field_focus');
}
});
// 输入框失去焦点时，样式设置
$('input').blur(function() {
$(this).removeClass('focus');
if ($(this).hasClass('have_tooltip')) {
$(this).parent().parent().removeClass('field_focus').addClass('field_normal');
}
});*/
});
