jQuery.validate usage

Monday, April 12, 2010 14:33

Name Return Type Description

validate(options) returns: Validator to verify the selected FORM

valid() returns: Boolean to check whether the verification is passed

rules() returns: Options Returns the validation rules of the element

rules(add,rules) returns: Options to add verification rules

rules(remove,rules)

jquery.validate is a very excellent verification framework based on jquery. We can quickly verify some common inputs through it, and can expand our own verification methods. It also has very good support for internationalization.

jquery.validate official website: http://bassistance.de/jquery-plugins/jquery-plugin-validation/

Usage:

1. First download jquery.js and jquery.validate.js and import the js file (note: jquery must be introduced before jquery.validate.js, otherwise an error will be reported)

<script type="text/javascript" src="jquery.js"></script> 
<script type="text/javascript" src="jquery.validate.js"></script>

2. Write the form code that needs to be verified and write the verification code (there are two ways to write verification code, first use the normal method)

var validator = $("formId").validate({// #formId为需要进行验证的表单ID
errorElement :"div",// 使用"div"标签标记错误， 默认:"label"
wrapper:"li",// 使用"li"标签再把上边的errorELement包起来
errorClass :"validate-error",// 错误提示的css类名"error"
onsubmit:true,// 是否在提交是验证,默认:true
onfocusout:true,// 是否在获取焦点时验证,默认:true
onkeyup :true,// 是否在敲击键盘时验证,默认:true
onclick:false,// 是否在鼠标点击时验证（一般验证checkbox,radiobox）
focusCleanup:false,// 当未通过验证的元素获得焦点时,并移除错误提示
rules: {
loginName: {// 需要进行验证的输入框name
required: true// 验证条件：必填
},
loginPassword: {// 需要进行验证的输入框name
required: true,// 验证条件：必填
minlength: 5// 验证条件：最小长度为5
},
email: {// 需要进行验证的输入框name
required: true,// 验证条件：必填
email: true// 验证条件：格式为email
}
},
messages: {
loginName: {
required: "用户名不允许为空!"// 验证未通过的消息
},
loginPassword: {
required: "密码不允许为空!",
minlength: jQuery.format("密码至少输入 {0} 字符!")
},
email: {
required: "email不允许为空",
email: "邮件地址格式错误!"
}
}

2. Use the meta String method for verification, that is, verify the content and write it into the class (note that the meta String method requires the introduction of the jquery.metadata.js file)

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.metadata.js"></script>
<script type="text/javascript" src="jquery.validate.js"></script>
<form id="validate" action="admin/transfer!save.action" method="post">
<input type="text" class="required" name="entity.name" />
<input type="text" class="email" name="entity.email" />
<input type="submit" class="button" value="提 交" />
</form>
<script type="text/javascript">
$(document).ready(
function() {
$("#formId").validate({// #formId为需要进行验证的表单ID
meta :"validate"// 采用meta String方式进行验证（验证内容与写入class中）
errorElement :"div",// 使用"div"标签标记错误， 默认:"label"
wrapper:"li",// 使用"li"标签再把上边的errorELement包起来
errorClass :"validate-error",// 错误提示的css类名"error"
onsubmit:true,// 是否在提交是验证,默认:true
onfocusout:true,// 是否在获取焦点时验证,默认:true
onkeyup :true,// 是否在敲击键盘时验证,默认:true
onclick:false,// 是否在鼠标点击时验证（一般验证checkbox,radiobox）
focusCleanup:false,// 当未通过验证的元素获得焦点时,并移除错误提示
});
})
</script>

Note: In Struts2 applications, we often encounter input forms in the form of name="entity.name" (that is, when the name contains commas or other special symbols), we can enclose the above name in quotation marks ("") That’s it, such as:

rules: {
"entity.loginName": {// 需要进行验证的输入框name
required: true// 验证条件：必填
}
},
messages: {
"entity.loginName": {
required: "用户名不允许为空!"// 验证未通过的消息
}
}

You can send me email: happyczx@126.com. Welcome to discuss issues related to java technology together

Part of the code above comes from the payj open source payment system. This java open source project contains many excellent application source codes of Struts2 spring hibernate jquery and other frameworks, which are worth a look. I would like to recommend it here first, haha. . .

ps: Jquery Validate verification rules

(1)required:true required field
(2)remote:”check.php” Use the ajax method to call check.php to verify the input value
(3)email:true You must enter an email in the correct format
(4)url:true You must enter the URL in the correct format
(5)date:true You must enter the date in the correct format
(6)dateISO:true You must enter the date (ISO) in the correct format, for example: 2009-06-23, 1998/01/22 Only the format is verified, not the validity
(7)number:true You must enter a legal number (negative number, decimal)
(8)digits:true must enter an integer
(9)creditcard: A legal credit card number must be entered
(10)equalTo:”#field” The input value must be the same as #field
(11)accept: Enter a string with a legal suffix (the suffix of the uploaded file)
(12)maxlength:5 Enter a string with a maximum length of 5 (Chinese characters count as one character)
(13)minlength:10 Enter a string with a minimum length of 10 (Chinese characters count as one character)
(14)rangelength:[5,10] The input length must be between 5 and 10") (Chinese characters count as one character)
(15)range:[5,10] The input value must be between 5 and 10
(16)max:5 The input value cannot be greater than 5
(17)min:10 The input value cannot be less than 10

Jquery Validate submit submit

submitHandler: The function that is run after passing verification must include the form submission function, otherwise the form will not be submitted
$(".selector").validate({ submitHandler:function(form) { $(form).ajaxSubmit(); //Use Jquery Form function } })

Jquery Validate error error prompt dom

.errorPlacement: Callback Default: Put the error message after the validated element
Specify the location where the error is placed. The default is: error.appendTo(element.parent()); that is, the error message is placed behind the verified element

errorPlacement: function(error, element) {
error.appendTo(element.parent());
}

Set the style of the error prompt, you can add icon display, like:

input.error { border: 1px solid red; }
label.error {
background:url(“./demo/images/unchecked.gif”) no-repeat 0px 0px;
padding-left: 16px;
padding-bottom: 2px;
font-weight: bold;
color: #EA5200;
}
