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
