1.html文件对话框的实现

<!DOCTYPE html>
    <html xmlns:th="http://www.thymeleaf.org">

        <meta charset="UTF-8">

    </head>
    <body>
    <b>个人信息页面</b><br>
    <label>id </label><b th:text="${session.user.getUserId()}"></b><br>
    <label>姓名 </label><b th:text="${session.user.getUserName()}"></b><br>
    <label>Email </label><b th:text="${session.user.getUserEmail()}"></b><br>
    <label>密码 </label><b th:text="${session.user.getUserPwd()}"></b><br>
    <button id="create-user">修改信息</button>
    <div id="dialog-form" title="修改信息">
        <p class="validateTips">所有的表单字段都是必填的。</p>
    
        <form id="updateUserform">
            <fieldset>
                <label for="name">名字</label>
                <input type="text" name="userName" id="name" class="text ui-widget-content ui-corner-all">
                <label for="email">邮箱</label>
                <input type="text" name="UserEmail" id="email" value="" class="text ui-widget-content ui-corner-all">
                <label for="password">密码</label>
                <input type="password" name="userPwd" id="password" value="" class="text ui-widget-content ui-corner-all">
            </fieldset>
        </form>
    </div>
    </body>
    </html>

2.html文件引用的updateUser.js文件

$(function() {
        var name = $( "#name" ),
            email = $( "#email" ),
            password = $( "#password" ),
            allFields = $( [] ).add( name ).add( email ).add( password ),
            tips = $( ".validateTips" );
    
        function updateTips( t ) {
            tips
                .text( t )
                .addClass( "ui-state-highlight" );
            setTimeout(function() {
                tips.removeClass( "ui-state-highlight", 1500 );
            }, 500 );
        }
    
        function checkLength( o, n, min, max ) {
            if ( o.val().length > max || o.val().length < min ) {
                o.addClass( "ui-state-error" );
                updateTips( "" + n + " 的长度必须在 " +
                    min + " 和 " + max + " 之间。" );
                return false;
            } else {
                return true;
            }
        }
    
        function checkRegexp( o, regexp, n ) {
            if ( !( regexp.test( o.val() ) ) ) {
                o.addClass( "ui-state-error" );
                updateTips( n );
                return false;
            } else {
                return true;
            }
        }
    
        $( "#dialog-form" ).dialog({
            autoOpen: false,
            height: 300,
            width: 350,
            modal: true,
            buttons: {
                "修改": function() {
                    var bValid = true;
                    allFields.removeClass( "ui-state-error" );
    
                    bValid = bValid && checkLength( name, "username", 3, 16 );
                    bValid = bValid && checkLength( email, "email", 6, 80 );
                    bValid = bValid && checkLength( password, "password", 5, 16 );
    
                    bValid = bValid && checkRegexp( name, /^[a-z]([0-9a-z_])+$/i, "用户名必须由 a-z、0-9、下划线组成，且必须以字母开头。" );

                    bValid = bValid && checkRegexp( email, /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i, "eg. ui@jquery.com" );
                    bValid = bValid && checkRegexp( password, /^([0-9a-zA-Z])+$/, "密码字段只允许： a-z 0-9" );
    
                    if ( bValid ) {
                       updateUser();//ajax更新用户信息
                        $( this ).dialog( "close" );
                    }
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            },
            close: function() {
                allFields.val( "" ).removeClass( "ui-state-error" );
            }
        });
    
        $( "#create-user" )
            .button()
            .click(function() {
                $( "#dialog-form" ).dialog( "open" );
            });
    });
    
    function updateUser() {
      $.ajax({
    
          async : false,
          type : 'post',
          url : '/updateUser',
          data : $('#updateUserform').serialize(),
          success : function(data) {
              alert("修改成功");
    
          },
          error : function(data) {
              alert("修改失败");
          }
      })  ;
    };

3.html文件引用的updateUser.css文件

body { font-size: 62.5%; }
    label, input { display:block; }
    input.text { margin-bottom:12px; width:95%; padding: .4em; }
    fieldset { padding:0; border:0; margin-top:25px; }
    h1 { font-size: 1.2em; margin: .6em 0; }
    div#users-contain { width: 350px; margin: 20px 0; }
    div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
    div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }
    .ui-dialog .ui-state-error { padding: .3em; }
    .validateTips { border: 1px solid transparent; padding: 0.3em; }

4.后端controller层对应的ajax请求方法

@Controller
    public class UserController {
    
        @Resource
        private IUserService userService;
    
      
        @RequestMapping("/updateUser")
        @ResponseBody
        public boolean updateUser(User user,HttpServletRequest request){
            return userService.updateUser(user,request);
        }
    }
