前端——JS實現多條件過濾數組

 通過js實現多條件過濾

//多條件過濾，array是傳入的數據，filters是過濾條件
multiFilter(array, filters) {
    filters = me.evtHandlers.removeEmpty(filters);
    const filterKeys = Object.keys(filters)
    return array.filter((item) => {
        return filterKeys.every(key => {
            if (!filters[key].length) return true
            return !!~filters[key].indexOf(item[key])
        })
    })
},
//去掉過濾條件值空的鍵
removeEmpty(obj) {
    obj = JSON.parse(JSON.stringify(obj))
    for (let k in obj) {
        v = obj[k];
        if (v === '') {
            delete obj[k];
        } else if (v.constructor == Object) {
            me.evtHandlers.removeEmpty(v);
        }
    }
    return obj
},
