topic:"名称"
},
{
dataContent:"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAArIA",
topic:"名称"
},
{
dataContent:"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAArIA",
topic:"名称"
}
]
vardata2=[
[
{content:"户籍一",grand:0,percent:0,resultCount:0,validPercent:0},
{content:"户籍二",grand:0,percent:0,resultCount:0,validPercent:0}
],
[
{content:"户籍一",grand:0,percent:0,resultCount:0,validPercent:0},
{content:"户籍二",grand:0,percent:0,resultCount:0,validPercent:0},
{content:"户籍二",grand:0,percent:0,resultCount:0,validPercent:0}
],
[
{content:"户籍一",grand:0,percent:0,resultCount:0,validPercent:0},
{content:"户籍二",grand:0,percent:0,resultCount:0,validPercent:0}
],
]
functionmergeData(data1,data2){
returndata1.map((item,index)=>({
...item,
exportContent:data2[index]
}))
}
console.log(mergeData(data1,data2))
