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!
uni-app提交form表单的两种方式
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'}"></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:

服务器返回数据,后续业务逻辑处理 }, fail: () => { uni.showToast({ title: "服务器响应失败,请稍后再试!", icon : "none"}); }, complete: () => {} }); } } } </script>
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JSONObject JSONObject 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(); }
