uniapp按钮防抖防止重复提交

电站新增时点击提交按钮,手速快的童鞋会提交多几个电站出来。为了解决这个问题,可以在提交按钮上做个防抖操作,下面直接上代码。

1.在根目录工具包utils里新建debounce.js文件

export const Debounce = (fn, wait) => {
    let delay = wait|| 500
    let timer
    return function () {
        let args = arguments;
        if (timer) {
            clearTimeout(timer)
        }

        let callNow = !timer

        timer = setTimeout(() => {
            timer = null
        }, delay)

        if (callNow) fn.apply(this, args)
    }
}

2.在add.vue里引用以上debounce.js

import { Debounce } from '@/utils/debounce.js'

3.在method添加方法

formSubmit: Debounce(function(e) {
                console.log('form发生了submit事件,携带数据为:' + JSON.stringify(e.detail.value))
                var formdata = e.detail.value
                formdata["image"] = uni.getStorageSync('uploadImg');
                this.addStation(formdata)
            },1000),

 

4.页面提交按钮

 

<template>
    <view class="contn">
        <!-- <page-head :title="ttitle"></page-head> -->
        <form @submit="formSubmit">

        <view class="ssm">
          <button class="logi" form-type="submit">
          <!-- 提交 -->
          <view class="logit">
            {{i18n.SBD_Submit}}
          </view>
          </button>
        </view>

          </form>

    </view>
</template>
