小程序里面有form表单组件，提交表单通过button提交，在form标签里添加bindsubmit事件，然后在button标签里面添加触发bindsubmit事件的属性：form-type=“submit”，就可以将表单提交到服务器了，需要注意的是button必须是要在form标签里面，例如：
<form bindsubmit="test"><button form-type="submit"></button></form>
提交表单的后续的操作写在bindsubmit事件里面：
test:function(){wx.navigateTo({url: '../../index/index',})}
这样点击button按钮时表单就已经提交上去了，并且随后会自动跳转到index界面，上一段结合weui工具写的发布商品的代码吧，wxml：
<form bindsubmit='release'><input class='ipt1' placeholder='为您的宝贝添加个诱人的标题吧（不超过30字）'></input><textarea class='ipt2' placeholder='更详细的介绍可以帮助更快送出，如品牌、市场价格、尺码、送出原因等（不少于10个字）'></textarea><view class="page__bd"><view class="weui-cells"><view class="weui-cell"><view class="weui-cell__bd"><view class="weui-uploader"><view class="weui-uploader__hd"><view class="weui-uploader__title">上传图片</view><!-- <view class="weui-uploader__info">{{files.length}}/9</view> --></view><view class="weui-uploader__bd"><view class="weui-uploader__files" id="uploaderFiles"><block wx:for="{{files}}" wx:key="*this"><view class="weui-uploader__file" bindtap="previewImage" id="{{item}}"><image class="weui-uploader__img" src="{{item}}" mode="aspectFill" /></view></block></view><view class="weui-uploader__input-box"><view class="weui-uploader__input" bindtap="chooseImage"></view></view></view></view></view></view></view></view><navigator url="/pages/address/address" open-type="navigateTo" class='order-bar' hover-class='none'><view class='order-list'><text>地址</text></view><image src='../../img/right-bar.svg'></image></navigator><view class="weui-cells weui-cells_after-title"><view class="weui-cell weui-cell_switch"><view class="weui-cell__bd" style='font-size:30rpx;color:#333;height:80rpx;padding:0rpx;line-height:65rpx'>全新</view><view class="weui-cell__ft" style='font-size:30rpx;color:#333;height:80rpx;padding:0rpx;line-height:60rpx'><switch /></view></view></view><view class='price'><view class='price1'><view class='price1-text1'>一口豆</view><view class='price1-text2'>竞拍</view></view><view class='price2'><view class='price2-text1'>一口豆</view><view class='price2-text2'>朵</view><input class='p-ipt' placeholder='50'></input></view><navigator url='../product-list/product-list' class='price3'><view class='price2-text1'>分类标签</view><image src='../../img/right-bar.svg' class='p-img'></image><view class='price2-text2'>请选择分类</view></navigator><view class='price3'><view class='price2-text1'>上门快递</view><image src='../../img/right-bar.svg' class='p-img'></image><view class='price2-text2'>普通快递</view></view></view><button class='btn' form-type='submit'>发布宝贝</button></form> <view class='foot'></view>
