我正在尝试使用"lodash": "^4.17.10"筛选对象。
请参阅以下我的最小可行示例：
const obj = {
"2": {
"title": "GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition",
"category": [{
"term_id": 34,
"name": "Graphic Card",
"slug": "graphic-card",
"term_group": 0,
}],
"currency": "$",
"price": "547.85",
"watt": "0",
},
"3": {
"title": "GeForce White Edition",
"category": [{
"term_id": 32,
"name": "other-card",
"slug": "other-card",
"term_group": 0,
}],
"currency": "$",
"price": "600.85",
"watt": "0",
}
}
let allGpuParts = _.pickBy(obj, (value, key) => {
return _.startsWith(key.category, "graphic-card")
})
console.log("allGpuParts")
console.log(allGpuParts)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>如您所能，目前没有返回结果。我只想取回"2":有子弹的物体"slug": "graphic-card"。
有什么建议如何用lodash过滤吗？
感谢您的答复！
您可以使用_.filter和_.isMatch查找要查找的键值对，_.some即表示是否匹配return true。
const obj = {
"2": {
"title": "GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition",
"category": [{
"term_id": 34,
"name": "Graphic Card",
"slug": "graphic-card",
"term_group": 0,
}],
"currency": "$",
"price": "547.85",
"watt": "0",
},
"3": {
"title": "GeForce White Edition",
"category": [{
"term_id": 32,
"name": "other-card",
"slug": "other-card",
"term_group": 0,
}],
"currency": "$",
"price": "600.85",
"watt": "0",
}
}
const isGPU = o => _.isMatch(o, {slug: "graphic-card"});
const allGpuParts = _.filter(obj, ({category}) => category.some(isGPU));
console.log("allGpuParts")
console.log(allGpuParts)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>如果我误解了或有任何疑问，请告诉我。
