vue pc端实现防抖的方法，记录一下，留待复用。

安装依赖

cnpm i lodash --save

引用依赖

import debounce from 'lodash/debounce'

使用

// 保存
saveData: debounce(function () {
  var that = this
  var applyCosts = []
  that.applyCosts.forEach((type) => {

      totalPrice: type.totalPrice
    }
    applyCosts.push(data)
  });
  var applyBaseInfo = {}
  // 校验数据
  try {
    var check = true
    that.applyForms.forEach((type, index) => {
      if (type.fieldValue) {
        applyBaseInfo[type.id] = type.fieldValue
      }
      if (!that.$refs[`vform${index}`][0].submitForm('ruleForm')) {
