First introduce the jquery Library 2. Introduction of the Validator Library 3. After the page is loaded successfully, specify the form you want to verify by $ (function () {$ ("selector"). Validate (); 4.validator method using $ ("selector"). Validate ({rules:{}//Rule messages:{}//hint}) 5. Common rules Required:true|false (required) number:true| False (value type must be filled) min:5 (minimum: The number written must be greater than five) Max:5 (maximum: The number written cannot be greater than five) Range:[min,max] (interval: The number written can only beThis interval) maxlength:minlength:rangelength:equalTo: "selector" (Password and Confirm password, so the element must be the same as in the selector) digits: integer (write-only integer) Email:email (mailbox authentication) 6. The write format of the rule: $ ("selector"). Validate ({rules:{//writing format}messages:{}}) write format: mode one: The Name property name of the field you want to validate: "Rule name" way two: the Name property name of the field you want to verify: {"Rule 1" : Value, "Rule 2": Value}7. Custom error message writing format: Mode one: The Name property name of the field that you want to validate: "Prompt message" way two: the Name property of the field you want to verify: {"Rule 1": "Prompt information 1", "Rule 2": "Hint Information 2"}8. Validate Custom Rule $.validator.addmethod (name,fn,message); Name: rule name Fn:function (value,element,params) {value: User input value element: The element itself params: parameter}//must have a return value Booleanmessage: Default prompt information extended content filtering: Children (): Gets child element parent (): Gets parent element Find (): Get descendant elements next (): Big Brother Nextall (): All Brother Prev (): Little Brother Prevall (): All Brother siblings (): All Brothers is (): Determine whether the specified element
