使用Vue搜索框和复选框过滤器 [英] Search Box and Checkbox filter with Vue

问题描述

我正在尝试使用Vue构建过滤系统。

I am trying to build filter system with Vue.

过滤器工作，但所有计算的函数是separeted函数。那么我如何在一个功能中使用它并使用它。

Filters working, but all the functions computed are separeted functions. So How can I make those in one function and use it.

export default {

    data() {
        return {
            estates: [],
            search: '',
            regions:['関西','関東','京橋'],
            checkedRegions:[]
        }
    },
    created(){
        axios.get('/ajax').then((response) => {
            this.estates = response.data;
        });
    },
    computed: {
        one: function() {
            var result =  this.estates.filter((estate) =>
                estate.building_name.match(this.search)
            );
            if(this.checkedRegions.length && this.checkedRooms.length) {
                return result.filter(estate => this.checkedRegions.includes(estate.region) && this.checkedRooms.includes(estate.rooms))
            }
            return result;
        }
    }
}

<div class="container-fluid">
        <div class="row">
            <div class="col-md-9">
                <input type="text" v-model="search" name="" placeholder="search estate" value="">
                <div v-for="estate in filteredestate" class="card-body">
                    <h2>{{estate.building_name}}</h2>
                    <p>{{estate.address}}</p>
                </div>
            </div>
        </div>
    </div>

filteredestate filteredRegions 和 filteredRooms 制作一个函数。例如，如何使用&& 返回这些功能？并在此div中使用它。

filteredestate filteredRegions and filteredRooms make one function. for example how to return those function with && ? And use it in this div.

<div v-for="estate in oneFunction" class="card-body">

推荐答案

首先将过滤搜索结果设置为变量，然后你可以通过或（||）表达式检查过滤器！

Set your filter search result first as variable and you can check filter by or(||) expression !

我通过设置为该变量并在最后一个上修改了此内部箭头功能行返回结果默认

I modified this inside arrow function by setting to that variable and on the last line return result as default

one: function() {
  var that = this;
  var result =  this.estates.filter((estate) =>
    estate.building_name == that.search;
  );
  if(this.checkedRegions.length || this.checkedRooms.length) {
    return result.filter(estate => that.checkedRegions.includes(estate.region) || that.checkedRooms.includes(estate.rooms))
    }
  // when region and room length is 0
  return result;
  }
}
