代码如下：

let tempArr = [];

let Data = [];

for (let i = 0; i < resData.length; i++) 

{ if (tempArr.indexOf(resData[i].tagName) === -1) { 

 Data.push({ tagName: resData[i].tagName, dataInfo: [resData[i]] }); tempArr.push(resData[i].tagName); 

 } else { for (let j = 0; j < Data.length; j++) {

 if (Data[j].tagName == resData[i].tagName) 

{ Data[j].dataInfo.push(resData[i]); break; } } } }

 console.log(Data);
