jquery的validate 里面怎么进行两个input必须有一个有值的验证?
这个插件默认是没有这个功能的,不过你可以自己写,这个插件是支持扩展的,你用这个jQuery.validator.addMethod *** ,你用这个插件的话,这个 *** 应该是知道的,它的参数可以设置参数,你把两个参数放到里边, *** 里边就按照你想要的比较,然后不符合你的效果,return false就可以
jquery 输入框校验
input id="Text1" type="text" /span id="Text1Note"/spanbr /
input id="Text2" type="text" /span id="Text2Note"/spanbr /
input id="Text3" type="text" /span id="Text3Note"/spanbr /
input id="Text4" type="text" /span id="Text4Note"/spanbr /
input id="Button1" type="button" value="button" onclick="return onsumbit()" /
script
//假设文本框1和3必须输入
//focusin事件为光标进入,focusout为光标离开
$("#Text1").focusin(function () {
$("#Text1Note").html("文本框1该项必须填写!");
}).focusout(function () {
if ($("#Text1").val() == "")
$("#Text1Note").html("文本框1该项必须填写!");
else
$("#Text1Note").html("");
});
$("#Text3").focusin(function () {
$("#Text3Note").html("文本框3该项必须填写!");
}).focusout(function () {
if ($("#Text3").val() == "")
$("#Text3Note").html("文本框3该项必须填写!");
else
$("#Text3Note").html("");
});
//不做任何输入直接提交执行提交执行
function onsumbit() {
if ($("#Text1").val() == "")
$("#Text1Note").html("文本框1该项必须填写!");
if ($("#Text3").val() == "")
$("#Text3Note").html("文本框3该项必须填写!");
return false;
}
/script
jquery中的表单验证if($.sValid()){是不是写错了?$.valid()这样写表单木有反应,改肿么写?
jQuery校验
官网地址:
一导入js库
script src="../js/jquery.js" type="text/javascript"/script
script src="../js/jquery.validate.js" type="text/javascript"/script
二、默认校验规则
(1)required:true 必输字段
(2)remote:"check.php" 使用ajax *** 调用check.php验证输入值
(3)email:true 必须输入正确格式的电子邮件
(4)url:true 必须输入正确格式的网址
(5)date:true 必须输入正确格式的日期 日期校验ie6出错,慎用
(6)dateISO:true 必须输入正确格式的日期(ISO),例如:2009-06-23,1998/01/22 只验证格式,不验证有效性
(7)number:true 必须输入合法的数字(负数,小数)
(8)digits:true 必须输入整数
(9)creditcard: 必须输入合法的信用卡号
(10)equalTo:"#field" 输入值必须和#field相同
(11)accept: 输入拥有合法后缀名的字符串(上传文件的后缀)
(12)maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
(13)minlength:10 输入长度最小是10的字符串(汉字算一个字符)
(14)rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
(15)range:[5,10] 输入值必须介于 5 和 10 之间
(16)max:5 输入值不能大于5
(17)min:10 输入值不能小于10
三、默认的提示
messages: {
required: "This field is required.",
remote: "Please fix this field.",
email: "Please enter a valid email address.",
url: "Please enter a valid URL.",
date: "Please enter a valid date.",
dateISO: "Please enter a valid date (ISO).",
dateDE: "Bitte geben Sie ein g眉ltiges Datum ein.",
number: "Please enter a valid number.",
numberDE: "Bitte geben Sie eine Nummer ein.",
digits: "Please enter only digits",
creditcard: "Please enter a valid credit card number.",
equalTo: "Please enter the same value again.",
accept: "Please enter a value with a valid extension.",
maxlength: $.validator.format("Please enter no more than {0} characters."),
minlength: $.validator.format("Please enter at least {0} characters."),
rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."),
range: $.validator.format("Please enter a value between {0} and {1}."),
max: $.validator.format("Please enter a value less than or equal to {0}."),
min: $.validator.format("Please enter a value greater than or equal to {0}.")
},
如需要修改,可在js代码中加入:
jQuery.extend(jQuery.validator.messages, {
required: "必选字段",
remote: "请修正该字段",
email: "请输入正确格式的电子邮件",
url: "请输入合法的网址",
date: "请输入合法的日期",
dateISO: "请输入合法的日期 (ISO).",
number: "请输入合法的数字",
digits: "只能输入整数",
creditcard: "请输入合法的信用卡号",
equalTo: "请再次输入相同的值",
accept: "请输入拥有合法后缀名的字符串",
maxlength: jQuery.validator.format("请输入一个 长度最多是 {0} 的字符串"),
minlength: jQuery.validator.format("请输入一个 长度最少是 {0} 的字符串"),
rangelength: jQuery.validator.format("请输入 一个长度介于 {0} 和 {1} 之间的字符串"),
range: jQuery.validator.format("请输入一个介于 {0} 和 {1} 之间的值"),
max: jQuery.validator.format("请输入一个更大为{0} 的值"),
min: jQuery.validator.format("请输入一个最小为{0} 的值")
});
推荐做法,将此文件放入messages_cn.js中,在页面中引入
script src="../js/messages_cn.js" type="text/javascript"/script
四、使用方式
1.将校验规则写到控件中
script src="../js/jquery.js" type="text/javascript"/script
script src="../js/jquery.validate.js" type="text/javascript"/script
script src="./js/jquery.metadata.js" type="text/javascript"/script
$().ready(function() {
$("#signupForm").validate();
});
form id="signupForm" method="get" action=""
p
label for="firstname"Firstname/label
input id="firstname" name="firstname" class="3893ffa0b98613f8 required" /
/p
p
label for="email"E-Mail/label
input id="email" name="email" class="ffa0b98613f8d0eb required email" /
/p
p
label for="password"Password/label
input id="password" name="password" type="password" class="b98613f8d0ebb2ec {required:true,minlength:5}" /
/p
p
label for="confirm_password"确认密码/label
input id="confirm_password" name="confirm_password" type="password" class="13f8d0ebb2ec9a93 {required:true,minlength:5,equalTo:'#password'}" /
/p
p
input class="998b704d1d732cff submit" type="submit" value="Submit"/
/p
/form
使用class="704d1d732cff90a6 {}"的方式,必须引入包:jquery.metadata.js
可以使用如下的 *** ,修改提示内容:
class="1d732cff90a66a5a {required:true,minlength:5,messages:{required:'请输入内容'}}"
在使用equalTo关键字时,后面的内容必须加上引号,如下代码:
class="2cff90a66a5af81f {required:true,minlength:5,equalTo:'#password'}"
2.将校验规则写到js代码中
$(document).ready(function() {
$("#signupForm").validate({
rules: {
firstname: "required",
email: {
required: true,
email: true
},
password: {
required: true,
minlength: 5
},
confirm_password: {
required: true,
minlength: 5,
equalTo: "#password"
}
},
messages: {
firstname: "请输入姓名",
email: {
required: "请输入Email地址",
email: "请输入正确的email地址"
},
password: {
required: "请输入密码",
minlength: jQuery.format("密码不能小于{0}个字 符")
},
confirm_password: {
required: "请输入确认密码",
minlength: "确认密码不能小于5个字符",
equalTo: "两次输入密码不一致不一致"
}
}
});
});
//messages处,如果某个控件没有message,将调用默认的信息
form id="signupForm" method="get" action=""
p
label for="firstname"Firstname/label
input id="firstname" name="firstname" /
/p
p
label for="email"E-Mail/label
input id="email" name="email" /
/p
p
label for="password"Password/label
input id="password" name="password" type="password" /
/p
p
label for="confirm_password"确认密码/label
input id="confirm_password" name="confirm_password" type="password" /
/p
p
input class="90a66a5af81f0750 submit" type="submit" value="Submit"/
/p
/form
required:true 必须有值
required:"#aa:checked"表达式的值为真,则需要验证
required:function(){}返回为真,表时需要验证
后边两种常用于,表单中需要同时填或不填的元素

jQuery.validator.format("请输入一个最小为 {0} 的值")
});
推荐做法,将此文件放入messages_cn.js中,在页面中引入
script src="../js/messages_cn.js"
type="text/javascript"/script
使用方式
1.将校验规则写到控件中
script src="../js/jquery.js"
type="text/javascript"/script
script
src="../js/jquery.validate.js"
type="text/javascript"/script
script
src="./js/jquery.metadata.js" type="text/javascript"/script
$().ready(function()
{
$("#signupForm").validate();
});
form id="signupForm" method="get"
action=""
label
for="firstname"Firstname/label
input id="firstname" name="firstname" class="6a5af81f075048b2 required"
/
label
for="email"E-Mail/label
input id="email" name="email" class="f81f075048b27a5d email required"
/
label
for="password"Password/label
input id="password" name="password" type="password"
class="075048b27a5ddd11 {required:true,minlength:5}"
/
label
for="confirm_password"确认密码/label
input id="confirm_password" name="confirm_password" type="password"
class="48b27a5ddd113893 {required:true,minlength:5,equalTo:'#password'}"
/
input class="7a5ddd113893ffa0 submit" type="submit"
value="Submit"/
/form
使用class="dd113893ffa0b986 {}"的方式,必须引入包:jquery.metadata.js
可以使用如下的 *** ,修改提示内容:
class="3893ffa0b98613f8 {required:true,minlength:5,messages:{required:'请输入内容'}}"
在使用equalTo关键字时,后面的内容必须加上引号,如下代码:
class="ffa0b98613f8d0eb {required:true,minlength:5,equalTo:'#password'}"
另外一个方式,使用关键字:meta(为了元数据使用其他插件你要包装 你的验证规则在他们自己的项目中可以用这个特殊的选项)
Tell the
validation plugin to look inside a validate-property in metadata for validation
rules.
例如:
meta: "validate"
input id="password" name="password"
type="password" class="b98613f8d0ebb2ec {validate:{required:true,minlength:5}}" /
再有一种方式:
$.metadata.setType("attr", "validate");
这样可以使用validate="{required:true}"的方式,或者class="13f8d0ebb2ec9a93 required",但class="998b704d1d732cff {required:true,minlength:5}"将不起作用
2.将校验规则写到代码中
$().ready(function()
{
$("#signupForm").validate({
rules:
{
firstname:
"required",
email:
{
required:
true,
email:
true
},
password:
{
required:
true,
minlength:
5
},
confirm_password:
{
required:
true,
minlength:
5,
equalTo:
"#password"
}
},
messages:
{
firstname:
"请输入姓名",
email:
{
required:
"请输入Email地址",
email:
"请输入正确的email地址"
},
password:
{
required:
"请输入密码",
minlength:
jQuery.format("密码不能小于{0}个字符")
},
confirm_password:
{
required:
"请输入确认密码",
minlength:
"确认密码不能小于5个字符",
equalTo:
"两次输入密码不一致不一致"
}
}
});
});
//messages处,如果某个控件没有message,将调用默认的信息
form id="signupForm" method="get"
action=""
label
for="firstname"Firstname/label
input id="firstname" name="firstname"
/
label
for="email"E-Mail/label
input id="email" name="email"
/
label
for="password"Password/label
input id="password" name="password" type="password"
/
label
for="confirm_password"确认密码/label
input
id="confirm_password" name="confirm_password" type="password"
/
input class="704d1d732cff90a6 submit" type="submit"
value="Submit"/
/form
required:true
必须有值
required:"#aa:checked"表达式的值为真,则需要验证
required:function(){}返回为真,表时需要验证
后边两种常用于,表单中需要同时填或不填的元素
常用 *** 及注意问题
1.用其他方式替代默认的SUBMIT
$().ready(function()
{
$("#signupForm").validate({
submitHandler:function(form){
alert("submitted");
form.submit();
}
});
});
可以设置validate的默认值,写法如下:
$.validator.setDefaults({
submitHandler:
function(form) { alert("submitted!");form.submit(); }
});
如果想提交表单, 需要使用form.submit()而不要使用$(form).submit()
2.debug,如果这个参数为true,那么表单不会提交,只进行检查,调试时十分方便
$().ready(function()
{
$("#signupForm").validate({
debug:true
});
});
如果一个页面中有多个表单,用
$.validator.setDefaults({
debug: true
})
3.ignore:忽略某些元素不验证
ignore: ".ignore"
4.errorPlacement:Callback
Default:
把错误信息放在验证的元素后面
指明错误放置的位置,默认情况是:error.appendTo(element.parent());即把错误信息放在验证的元素后面
errorPlacement:
function(error, element)
{
error.appendTo(element.parent());
}
Jquery验证只能验证表单吗,能验证表单里指定的DIV吗
是的,要写好校验规则。
1、将校验规则写到控件中
script src="../js/jquery.js" type="text/javascript"/script
script src="../js/jquery.validate.js" type="text/javascript"/script
script src="./js/jquery.metadata.js" type="text/javascript"/script
$().ready(function() {
$("#signupForm").validate();
});
form id="signupForm" method="get" action=""
p
label for="firstname"Firstname/label
input id="firstname" name="firstname" class="1d732cff90a66a5a required" /
/p
p
label for="email"E-Mail/label
input id="email" name="email" class="2cff90a66a5af81f required email" /
/p
p
label for="password"Password/label
input id="password" name="password" type="password" class="90a66a5af81f0750 {required:true,minlength:5}" /
/p
p
label for="confirm_password"确认密码/label
input id="confirm_password" name="confirm_password" type="password" class="6a5af81f075048b2 {required:true,minlength:5,equalTo:'#password'}" /
/p
p
input class="f81f075048b27a5d submit" type="submit" value="Submit"/
/p
/form
2.将校验规则写到js代码中
$().ready(function() {
$("#signupForm").validate({
rules: {
firstname: "required",
email: {
required: true,
email: true
},
password: {
required: true,

},
confirm_password: {
required: true,
minlength: 5,
equalTo: "#password"
}
},
messages: {

required: "请输入密码",
minlength: jQuery.format("密码不能小于{0}个字 符")
},
confirm_password: {

minlength: "确认密码不能小于5个字符",
equalTo: "两次输入密码不一致不一致"
}
}
});
});
