今天小編就為大家分享一篇js根據(jù)json數(shù)據(jù)中的某一個屬性來給數(shù)據(jù)分組的方法，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

如下所示：

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
	</head>
	<body>
		<span id ="span" style="width: 50px;height: 200px;"></span>
	</body>
	<script>
	var arr = [{"Group":1,"Groupheader":"質(zhì)量管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":1,"Groupheader":"","Leftimg":"","Left":"","Min":"質(zhì)量巡檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"設(shè)備管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備專業(yè)點檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備日檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備周檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)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(shù)據(jù)：

[{"Group":1,"Groupheader":"質(zhì)量管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":1,"Groupheader":"","Leftimg":"","Left":"","Min":"質(zhì)量巡檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"設(shè)備管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備專業(yè)點檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備日檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備周檢","Right":"","Rightimg":""},
{"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"設(shè)備月檢","Right":"","Rightimg":""}];

處理后的數(shù)據(jù)：

[
 {
  "Group": 1,
  "data": [
   {
    "Group": 1,
    "Groupheader": "質(zhì)量管理",
    "Leftimg": "",
    "Left": "",
    "Min": "",
    "Right": "",
    "Rightimg": ""
   },
   {
    "Group": 1,
    "Groupheader": "",
    "Leftimg": "",
    "Left": "",
    "Min": "質(zhì)量巡檢",
    "Right": "",
    "Rightimg": ""
   }
  ]
 },
 {
  "Group": 2,
  "data": [
   {
    "Group": 2,
    "Groupheader": "設(shè)備管理",
    "Leftimg": "",
    "Left": "",
    "Min": "",
    "Right": "",
    "Rightimg": ""
   },
   {
    "Group": 2,
    "Groupheader": "",
    "Leftimg": "",
    "Left": "",
    "Min": "設(shè)備專業(yè)點檢",
    "Right": "",
    "Rightimg": ""
   },
   {
    "Group": 2,
    "Groupheader": "",
    "Leftimg": "",
    "Left": "",
    "Min": "設(shè)備日檢",
    "Right": "",
    "Rightimg": ""
   },
   {
    "Group": 2,
    "Groupheader": "",
    "Leftimg": "",
    "Left": "",
    "Min": "設(shè)備周檢",
    "Right": "",
    "Rightimg": ""
   },
   {
    "Group": 2,
    "Groupheader": "",
    "Leftimg": "",
    "Left": "",
    "Min": "設(shè)備月檢",
    "Right": "",
    "Rightimg": ""
   }
  ]
 }
]
