【js数组对象合并相同ID的对象】

背景：dbc文件配置 将fileid一直的signal合并在一起

意指将

[fileId: “239”,signal:{CDU_4:[‘CDU_NavilimitSpdVD’,‘CDU_ICM_ModeSet’]}

[fileId: “239”,signal:{TheMessage:[‘TheSignal’]}中ID相同的signal进行合并 组成新的数组

成为

[fileId: “239”,signal:{TheMessage:[‘TheSignal’]，CDU_4:[‘CDU_NavilimitSpdVD’,‘CDU_ICM_ModeSet’]}

wrapFiles.forEach((item) => {var dataItem = item;if (newArr.length > 0) {var filterValue = newArr.filter((v) => {return v.fileId === dataItem.fileId;});if (filterValue.length > 0) {newArr.forEach((n) => {console.log(newArr);if (n.fileId === filterValue[0].fileId) {n.signals = Object.assign(filterValue[0].signals, dataItem.signals);}});} else {newArr.push(dataItem);}} else {newArr.push(dataItem);}});
