现在我只想获取特定类别的数据。例如，我只想获取工具和机械类别的数据。我该怎么做，请帮忙

Answer 1

const data = {"statusCode":200,"status":"SUCCESS","responseContents":[{"webimage":[],"appimage":[],"_id":"6155c2c77f31f9b79ba4273b","Categories":"Tools & Machineries","Subcategories":["Power & Hand Tools ","Plant Cutting tools","All Tools & Home Improvement","Tool Storage & Organization","Tool Organisers","Pneumatic Tools","Carbide Cutting Tools","Tool Storage & Organization","Tools & Workshop Equipment","TOOLS & EQUIPMENTS","Hand Tools"]},{"webimage":[],"appimage":[],"_id":"6155c2c77f31f9b79ba4273c","Categories":"Furniture","Subcategories":["Wooden Furniture","Office Furniture","Kitchen Furniture","Modular Office Furniture","Industrial Furniture","Steel Furniture","Living Room Furniture","|Storage and Display Furniture","Entryway Furniture","Inflatable Furniture","Patio Furniture & Accessories","Storage and Display Furniture"," Office & Commercial Furniture "]},{"webimage":[],"appimage":[],"_id":"6155c2c77f31f9b79ba4273d","Categories":"Safety & Security","Subcategories":["Industrial Safety Equipments","Safety Equipment","Fire Fighting Equipments","Traffic Safety Equipment","Marine Safety Equipment","Welding Safety Accessories","Work Safety Equipment & Gear","PERSONAL PROTECTION EQUIPMENTS","General Safety Equipment "," Fire Fighting & Prevention Products ","SAFETY MATERIALS (PPE)"]},{"webimage":[],"appimage":[],"_id":"6155c2c77f31f9b79ba4273e","Categories":"Lighting","Subcategories":["LED COMMERCIAL LIGHTING","Panel Light","Ceiling Lights","Indoor Lighting ","Flood Lights","Lighting Fixtures ","Lights & Fittings"," Indoor Lights & Lighting Accessories"]}]};

function getBySubCategory(dataSet, category){
  return dataSet.find(o => o.Categories===category);
}

const dataSet = data.responseContents;
console.log(getBySubCategory(dataSet, 'Tools & Machineries'));
console.log(getBySubCategory(dataSet, 'Safety & Security'));
