需要引入jquery.form.js

自定義方法：

// 匹配english
jQuery.validator.addMethod(“isEnglish”, function(value, element) {
return this.optional(element) || /^[A-Za-z]+$/.test(value);
}, “匹配english”);

提交：

var FormValidation = function () {

return {
    //main function to initiate the module
    init: function () {

        // for more info visit the official plugin documentation: 
        // http://docs.jquery.com/Plugins/Validation

        var form1 = $('#fromAddOrEdit');
        var error1 = $('.alert-danger', form1);
        var success1 = $('.alert-success', form1);         

       form1.validate({
            errorElement: 'span', //default input error message container
            errorClass: 'help-block', // default input error message class
            focusInvalid: false, // do not focus the last invalid input
