這篇文章主要介紹js如何根據json數據中的某一個屬性來給數據分組，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！
如下所示：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<span id ="span" ></span>
</body>
<script>
var arr = [{"Group":1,"Groupheader":"質量管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":1,"Groupheader":"","Leftimg":"","Left":"","Min":"質量巡檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"設備管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備專業點檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備日檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備周檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備月檢","Right":"","Rightimg":""}];
var map = {},
dest = [];
for(var i = 0; i < arr.length; i++){
var ai = arr[i];
if(!map[ai.Group]){
dest.push({
Group: ai.Group,
data: [ai]
});
map[ai.Group] = ai;
}else{
for(var j = 0; j < dest.length; j++){
var dj = dest[j];
if(dj.Group == ai.Group){
dj.data.push(ai);
break;
}
}
}
}
console.log(JSON.stringify(dest));
var sapn = document.getElementById("span");
span.innerHTML = JSON.stringify(dest);
</script>
</html>原始數據：
[{"Group":1,"Groupheader":"質量管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":1,"Groupheader":"","Leftimg":"","Left":"","Min":"質量巡檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"設備管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備專業點檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備日檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備周檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設備月檢","Right":"","Rightimg":""}];處理后的數據：
