uni-app中怎么提交form表单？下面本篇文章就来给大家分享下两种uni-app提交form表单的方式，希望对大家有所帮助！

方式1：form表单元素较少

比如用户登录，如下图

前端代码举例

此处省略了部分多余代码

<template><view style="padding:50rpx;"><view style="margin-top:60rpx;"><form @submit="submit"><view class="gui-border-b gui-form-item" style="margin-top:80rpx;"><view class="gui-form-body"><input type="number" class="gui-form-input" v-model="driverTel" name="driverTel" placeholder="手机号" placeholder-style="color:#CACED0"/></view></view><view class="gui-border-b gui-form-item" style="margin-top:30rpx;"><view class="gui-form-body"><input type="password" class="gui-form-input" v-if="isPwd" v-model="password" name="password" placeholder="密码" placeholder-style="color:#CACED0"/><input type="text" class="gui-form-input" v-if="!isPwd" :disabled="true" v-model="password" name="password" placeholder="密码" placeholder-style="color:#CACED0"/></view><text class="gui-form-icon gui-icons gui-text-center" @click="changePwdType" :style="{color:isPwd?'#999999':'#008AFF'}">&#xe609;</text></view><view style="margin-top:50rpx;"><button type="default" class="gui-button gui-bg-blue msgBtn" formType="submit" style="border-radius:50rpx;"><text class="gui-color-white gui-button-text-max">登录</text></button></view></form></view></view></template><script>uni.request({url: _self.server_host + "/app/driver/login/password",method:'POST',header:{'content-type' : "application/x-www-form-urlencoded"},data:{// 对于上面的form表单提交，我们可以直接在uni.request的data属性中直接提交就行了driverTel: _self.driverTel,password: _self.password},success: (res) => {// 服务器返回结果}})</script>

后端代码举例

/*** 这里可以以一个实体类来接收，实体类必须包含前端传参参数的对应字段*/@PostMapping("/password")public Result loginByPassword(LoginUserVO loginUserVO) {// 处理业务逻辑}/*** 也可以按照字段名来接收*/@PostMapping("/password")public Result loginByPassword(String username, String passsword) {// 处理业务逻辑}

方式1：form表单元素较多

上面的方法在form表单元素较多时处理起来就比较费事了，一般像新增用户、商品之类的form表单少则十几个，多则几十个。如下图： 如果按照上面的写法，不仅前端写起来费事不雅观，后台接受也要一个字段一个字段的接收也煞是费劲，这个时候我们可以定义一个对象formData，将数据保存到里面提交时直接提交JSON字符串到后端，后端接收到JSON字符串后转成JSON对象，然后再进行自己的业务逻辑处理

前端代码举例：

后端java代码举例

// 针对传参方式一：后台以String的方式接收public Result add(String formData){// 将JSON字符串转换成JSONObjectJSONObject jsonObject= JSONObject.parseObject(formData);// 继续后续业务逻辑处理return Results.success();}// 针对传参方式二：后台以Object的方式接收public Result add(Object driverObj){// 继续后续业务逻辑处理return Results.success();}
