前端——JS实现多条件过滤数组

//多条件过滤，array是传入的数据，filters是过滤条件
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])
        })
    })
},
//去掉过滤条件值空的键
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
},
