The front end realizes the real-time search of the input box, [vue+el-input]

The general search is to adjust the back-end interface, bind the searchValue field (or other field names), and perform real-time search through the back-end interface

It is also simple if the search filter is implemented by the front end itself

1. input event

 <el-input
          v-model="queryParams.searchValue"
          @input="keywordChange($event)"       
          clearable
          style="width: 180px"      
        />

2. When binding the data source, judge whether to use the filter array or the original array according to the conditions

  <el-table
          ref="elTable"
          class="mblclass"
          border
          :data="filterList.length?filterList:datalist"   
          style="font-size: 14px"
        >

3. Define data in data

 data() {
    
    
    return {
    
    
      datalist: [],//原数组
      filterList:[],//过滤数组

}}

4. Get the data of the original array first

  async getdata() {
    
    
      {
    
    
        try {
    
    
          const res = await getlistdata()
          this.datalist = res.data.list
          this.total = Number(res.data.totalRow)         
        } catch (error) {
    
    
        }
      }
    },

5. Input box input event

    //关键字搜索
    keywordChange(keywords) {
    
    
      this.filterList = this.seachArray(this.datalist, keywords)
      this.total = this.filterList.length
    },
    
        seachArray(arr, keyword) {
    
    
      const newArr = arr.filter(item => {
    
    
      //toUpperCase()将输入内容与对应的字段都转换为大写，这样可以实现不区分大小写，都能搜索到
        return item.code.toUpperCase().includes(keyword.toUpperCase()) ||      item.name.toUpperCase().includes(keyword.toUpperCase())
      })
      return newArr
    },
