form表單頁面程式碼

<form id="formDemo" class="layui-form">
    <table class="layui-table" lay-even>
        <colgroup>
 

            <col width="100">
            <col width="200">
            <col>
        </colgroup>
        <tbody>
            <tr>
                <th>使用者名稱</th>
                <td id="userName">
                    <div class="layui-form-item layui-input-inline"
 
>
                        <input tyep="text" name="userName" class="layui-input">
                    </div>
                </td>
            </tr>
            
            
            <tr>
                <th>登入密碼</th>
                <td id="password">
 

                    <div class="layui-form-item layui-input-inline">
                        <input tyep="text" name="password" class="layui-input">
                    </div>
                </td>
            </tr>
            
            <tr>
                <th>使用者許可權</th>
                <td id="role">
                    <div class="layui-form-item layui-input-inline">
                      <input type="text" name="role" class="layui-input" readOnly="true" value="管理員">
                    </div>
                </td>
            </tr>
            <tr>
                <th>手機號</th>
                <td id="phone">
                    <div class="layui-form-item layui-input-inline">
                        <input tyep="text" name="phone" class="layui-input">
                    </div>
                </td>
            </tr>
            <tr>
                <th>使用者備註</th>
                <td id="nickName">
                    <div class="layui-form-item layui-input-inline">
                        <input tyep="text" name="nickName" class="layui-input">
                    </div>
                </td>
            </tr>
            
        </tbody>
    </table>
 </form>

序列化

<script type="text/javascript">
    function getUser(){
        console.log($('#formDemo').serializeJSON());
        console.log(JSON.stringify($('#formDemo').serializeJSON()));
        return JSON.stringify($('#formDemo').serializeJSON());
    }
</script>

$('#formDemo').serializeJSON()返回的是一個Object體

{userName: "test", password: "test", role: "管理員", phone: "18888888866", nickName: "測試"}

JSON.stringify($('#formDemo').serializeJSON())返回的是JSON字串

{"userName":"test","password":"test","role":"管理員","phone":"18888888866","nickName":"測試"}

使用Ajax傳遞給後臺使用@RequestBody進行接收

<script type="text/javascript">
    function addUser(){
        var data = getUser();
        $.ajax({
         type: "POST",
         url: "${ctx}/auth/user/create",
         data: data,
         dataType: "json",
         contentType:"application/json",
         success: function(data){
            alert(data.message);
             if(data.code==0){
                 layer.closeAll();
                 window.location.href="${ctx}/auth/users";
             }
          }
        });
    }
    
</script>

若要在JS中獲取鍵值對中的值可以進行如下處理

<script type="text/javascript">
    var data = getUser();
    var obj = eval("("+data+")");
    alert(obj.userName);
    
</script>
