Javascript中实现JSON数组多键值排序

①首先在后台使用C#获取数据库中的菜单数据,生成一个包含菜单数据项的JSON数组(由于某种原因没有使用SQL中的ORDER BY),如下:

view sourceprint?var menuData1=[

{"orderid":-10,"text":"主页","title":"个人网站主页","url":"Default.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":10,"text":"个人新闻","title":"个人新闻","url":"News.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":5,"text":"发表论文","title":"发表论文","url":"Paper.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":2,"text":"出版专著","title":"出版专著","url":"Monograph.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":7,"text":"参与项目","title":"参与项目","url":"Project.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":8,"text":"个人荣誉","title":"个人荣誉","url":"Prize.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":1,"text":"发明专利","title":"发明专利","url":"Patent.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":0,"text":"文件共享","title":"文件共享","url":"FileShare.aspx?TeacherID=153","visible":true,"target":"_self"}

];

②这时需要先将数组按orderid升序排序,注意,sort方法会改写原来的数组

view sourceprint?menuData1.sort(function(a, b) { return a.orderid > b.orderid ?1 : -1;} );//

③经过排序后,结果为:

view sourceprint?menuData1=[

{"orderid":-10,"text":"主页","title":"个人网站主页","url":"Default.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":0,"text":"文件共享","title":"文件共享","url":"FileShare.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":1,"text":"发明专利","title":"发明专利","url":"Patent.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":2,"text":"出版专著","title":"出版专著","url":"Monograph.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":5,"text":"发表论文","title":"发表论文","url":"Paper.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":7,"text":"参与项目","title":"参与项目","url":"Project.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":8,"text":"个人荣誉","title":"个人荣誉","url":"Prize.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":10,"text":"个人新闻","title":"个人新闻","url":"News.aspx?TeacherID=153","visible":true,"target":"_self"}
