Vue 的forEach和push

tagTacticsFilter(tacticsTag) {
            let data = []
            let _tacticsTagList = this.tacticsTagList
            let attrList = tacticsTag.split(',')
            attrList.forEach(function(item) {//循环
                _tacticsTagList.forEach(function(c) {
                    if (item === c.dataSubtype) {
                        data.push(c.dataSubtypeName)//往数组中放数据
                    }
                })
            })
            return data
        },

通过过滤条件返回新的data数组
