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：
[ { "Group": 1, "data": [ { "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, "data": [ { "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": "" } ] }]以上這篇js根據json數據中的某一個屬性來給數據分組的方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林網。
