Jquery Validate Validation rules

(1) Required:true must lose field
(2) Remote: "check.php" using Ajax method call check.php Validate input value
(3) Email:true must enter the correct format of e-mail
(4) Url:true must enter the correct format of the URL
(5) Date:true must enter the correct format date
(6) Dateiso:true must enter the correct format for the date (ISO), for example: 2009-06-23, 1998/01/22 only verify the format, do not verify the validity
(7) Number:true must enter a valid number (negative, fractional)
(8) Digits:true must enter an integer
(9) CreditCard: Must enter a valid credit card number
Equalto: The "#field" input value must be the same as #field
(one) Accept: Enter a string with a valid suffix (the suffix of the uploaded file)
Maxlength:5 input string with a maximum length of 5 (Chinese characters are counted as one character)
(minlength:10) Enter a string with a minimum length of 10 (Chinese characters are counted as one character)
(rangelength:[5,10] Enter a string that must be between 5 and 10 in length) (Chinese characters are counted as one character)
(range:[5,10] Input value must be between 5 and 10
(+) Max:5 input value cannot be greater than 5
(min:10) input value cannot be less than 10

Jquery Validate Custom validation rules

Addmethod (Name,method,message) method:
Parameter name is the name of the method added
The parameter method is a function that receives three parameters (Value,element,param) value is the values of the element, element is the elements themselves param
is a parameter, we can use Addmethod to add a validation method other than built-in Validation methods, such as having a field,
Can lose a letter, the range is a-f, the wording is as follows:

$.validator.addmethod ("AF", function (value,element,params) {
if (value.length>1) {
return false;
}
if (Value>=params[0]&&value<=params[1]) {
return true;
}else{
return false;
}
}, "must be a letter, and a-f");
Id= "username" in a form field, write in rules
username:{
Af:["A", "F"]
}
Method
The first parameter of the Addmethod is the name of the added validation method, which is the AF
The third parameter of Addmethod is the custom error prompt, where the prompt is: "must be a letter, and A-f"
The second parameter of the Addmethod is a function, which is more important and determines how to use this verification method.
If there is only one parameter, write directly, if AF: "A", then A is the only parameter, if multiple parameters, used in [], separated by commas

Jquery Validate Submit Submission

Submithandler: A function that runs after validation, which is added to the form-submitted function, or the form is not submitted

$ (". Selector"). Validate ({   submithandler:function (form) {$ (form). Ajaxsubmit ();          function with jquery form   }})

Jquery Validate error Bug tip Dom

. Errorplacement:callback Default: Put the error message behind the validated element
Indicates where the error is placed, by default: Error.appendto (Element.parent ()), where the error message is placed after the element being validated
Errorplacement:function (Error, Element) {
Error.appendto (Element.parent ());
}

Set the style of the error prompt, you can increase the icon display, Like:input.error {border:1px solid red;}
Label.error {
Background:url ("./demo/images/unchecked.gif") No-repeat 0px0px;  padding-left:16px;  padding-bottom:2px;  Font-weight:bold; Color: #EA5200;
