赋值清空的简写

在后台管理系统里面,最常见的是就是编辑弹框,赋值,当值很多的时候,我们可以简写,而不是一长串的写出来
来来来,错误示范
在data里面去定义

   formSearch: {
        page: 1,
        size: 10,
        entName: '',
        brandIds: [],
        seriesId: '',
        modelId: '',
        status: [],
        timeRange: '',
        beginSearchTime: '',
        endSearchTime: '',
        needLoad: '',
        bocStatus: [],
        searchNo: '',
        buyerName: '',
        endUserProvince: '',
        endUserCity: '',
        endUserDistrict: '',
        minOfferNum: '',
        maxOfferNum: '',
        belongName: '',
        addFrom: [],
        deptName: '',
        bigDeptName: '',
        buyerDeptCode: '',
        defeatReason: ''
      },

清空时去赋值

 clearFilter () {
      this.formSearch.page = 1
      this.formSearch.entName = ''
      this.formSearch.belongName = '' 
      this.formSearch.brandIds = []
      this.formSearch.seriesId = ''
      this.formSearch.modelId = '' 
      this.formSearch.timeRange = ''
      this.formSearch.beginSearchTime = ''
      this.formSearch.endSearchTime = ''
      this.formSearch.needLoad = ''
      this.formSearch.searchNo = ''
      this.formSearch.buyerName = '' 
      this.formSearch.endUserProvince = '' 
      this.formSearch.endUserCity = ''
      this.formSearch.endUserDistrict = ''
      this.formSearch.minOfferNum = ''
      this.formSearch.maxOfferNum = ''  
      this.formSearch.addFrom = [] 
      this.formSearch.deptName = ''
      this.formSearch.bigDeptName = ''
      this.formSearch.buyerDeptCode = '' 
      this.formSearch.defeatReason = '' 
      this.getTargetCarList()
      localStorage.removeItem('initTime')
    },

是不是看不下去?
下面示范正确的
1.首先我们可以在data的return外面去定义一个常量,然后赋值

    let defaultAddParams = {
      planName: '',
      expressionName: '',
      effectiveTime: '',
      exclusivePlan: [],
      relyPlan: [],
      expiryTime: '',
      expressionId: '',
      expressionDescribe: '',
      planDescribe: '',
      planCode: '',
      templateType: '',
      lycTopTips: '',
      lycOrderTips: '',
      isLycTips: '',
      czgTopTips: '',
      czgOrderTips: '',
      orderRemark: '',
      marketingType: '',
      isCzgTips: '',
      planSort: '',
      planPdfUrl: '',
      putInType: '',
      putInDesc: '',
      putInPoints: '',
      putInNotPoints: '',
      putInRemark: '',
      putInImg: '',
      putInText: '',
      putInIsShow: '',
      expressionCn: '',
      expression: '',
      expressionId: ''
    }
    return {
      defaultAddParams,
      planAddParams: defaultAddParams,
    }

编辑时赋值

editPlan (item) {
    for (var key in this.defaultAddParams) {
        this.defaultAddParams[key] = ''
      }
      this.defaultAddParams.exclusivePlan = []
      this.defaultAddParams.relyPlan = []
      Object.keys(this.defaultAddParams).forEach(key => {
        item[key] ? this.planAddParams[key] = item[key] : this.planAddParams[key] = this.defaultAddParams[key]
      })
      this.planAddParams.expressionDescribe = ''
      this.planAddParams.expressionCn = ''
}

ps:先对原始的数据可以做一个清空,再去判断这个item里面有没有返回这个值,如果有就赋值,没有用原来的值

清空
直接对数据进行forEach清空就好
