對數據作分頁處理

最近在寫vue的項目,由於後臺返回的數據量太大,致使頁面卡死直接蹦掉了,而後後臺小哥哥和我講能夠分批處理~沒想到真的是快了不少不少,眼過千變不如手過一遍~,在此記錄一下!!! 首先咱們要定義兩個變量:
vue

data() { page: 0, number: 1 }ios


methods:{
getData(){
    this.$axios.post("/api/XXX", {}).then(res=>{
        if (res.data.rows) {
              let inquiryRelates = res.data.rows.InquiryRelates;
              if (inquiryRelates.length < 5) {
                this.InquiryRelates = inquiryRelates;
                this.loadData = false;
              } else {
                this.lazyLoadCount(this.page, this.number, inquiryRelates);
            } 
        }
    })
}
lazyLoadCount(page, number, inquiryRelates) {
  this.InquiryRelates = this.InquiryRelates.concat(inquiryRelates.slice(page, number));
  if (this.InquiryRelates.length < inquiryRelates.length) {
    setTimeout(() => {
      this.page += 1;
      this.number += 1;
      this.lazyLoadCount(this.page, this.number, inquiryRelates);
    }, 1000);
  } else {
    this.loadData = false;
  }
},
複製代碼

}axios
