Jquery.validate Official Website: http://bassistance.de/jquery-plugins/jquery-plugin-validation/usage: 1, First download jquery.js and jquery.validate.js and introduce JS file (Note: jquery must be introduced before jquery.validate.js, otherwise it will be an error) <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 validated and write the verification code (there are two ways to write the validation code, first use the normal way) var validator = $ ("FormId"). Validate ({//#formId为需要进行验证的表单ID Errorelement: "div",//use "div" tag tag error, default: "Label" wrapper: "Li",//Use "Li" label and then wrap the top errorelement errorclass: " Validate-error ",//Error prompt CSS class name" Error "onsubmit: true,//Whether the commit is validation, default: True onfocusout: true,//whether to validate when getting focus, default: True onkeyup: true,//whether to verify when tapping the keyboard, default: True onclick: false,//whether to validate on mouse click (General authentication Checkbox,radiobox) Focuscleanup: false,
