jquery.validate 以alert方式显示错误方法
虽然alert方式不被推荐,但很多时候由不得我...
$.validator.setDefaults({submitHandler: function() { alert("submitted!");return false; }});$().ready(function() {// validate signup form on keyup and submit$("#reg_form").validate({rules: {/* input name 有 . 时加上引号 */'mem.username': {required: true,minlength: 5},'mem.password': {required: true,minlength: 5}},messages: {'mem.username': {required: "Please provide a password",minlength: "Your password must be at least 5 characters long"},'mem.password': {required: "Please provide a password2",minlength: "Your password must be at least 5 characters long"}},/* 重写错误显示消息方法,以alert方式弹出错误消息 */showErrors: function(errorMap, errorList) {var msg = "";$.each( errorList, function(i,v){ msg += (v.message+"\r\n");});if(msg!="") alert(msg); }, /* 失去焦点时不验证 */ onfocusout: false});});
