已知數據vartableData=[{val:"紅",val1:"大",val2:"五邊形",val3:"1*222"},{val:"綠",val1:"大",val2:"6邊形",val3:"1*2224"},{val:"紅",val1:"大",val2:"五邊形",val3:"1*222"}]預期結果varresult=[['紅'，'綠'],['大'],['五邊形','6邊形'],["1*222","1*222"]]目前做法varcc=[]tableData.map((item,index)=>{console.log(item,index)vararr=[]varobj={}for(varkeyinitem){if(key!=='price'){obj[key]=item[key]arr.push(obj[key])console.log(arr)}console.log(key,item[key])}cc.push(arr)})console.log(cc)vardd=[];for(vari=0;i

functiontranslate(tableData){letkeyArr=['val','val1','val2','val3'];lettempResult=keyArr.map(item=>{returntableData.map(_item=>{return_item[item];})});console.log(tempResult);returntempResult.map(item=>{return[...newSet(item)];})}//測試translate([{val:"紅",val1:"大",val2:"五邊形",val3:"1*222"},{val:"綠",val1:"大",val2:"6邊形",val3:"1*2224"},{val:"紅",val1:"大",val2:"五邊形",val3:"1*222"}]);
