retrieve data from c# linq object to json to html - asp.net-mvc-3

Question

Retrieve code from json.
C#code:-
var collection = getsortcat.Select(x => new
{
idterm = x.IDTerm,
mvo = x.MVO,
pic = x.Pic,
said = x.SAid,
termactive = x.TermActive,
vid = x.Vid,
fvo = x.FVO,
eterm = x.ETerm,
edef = x.EDef,
buse = x.BUse,
bterm = x.BTerm,
idcat = x.TermCat,
items = x.TermCategory1.IDCat,
catname = x.TermCategory1.TermCategory1
});
JavaScriptSerializer jss = new JavaScriptSerializer();
string output = jss.Serialize(collection);
return Json(output, JsonRequestBehavior.AllowGet);
Javascript Code:-
success: function (e) {
var txt = "'{ data :" + e + "}'";
var obj = eval("(" + txt + ")");
$('#pdata').append(obj.data[0]);
},
Not getting output. Please give me solution how to retrieve data from c# linq object to json to html?

Answer 1

First fix your controller action to get rid of any JavaScriptSerializers and manual plumbing code. Directly return the collection to the Json result:
var collection = getsortcat.Select(x => new
{
idterm = x.IDTerm,
mvo = x.MVO,
pic = x.Pic,
said = x.SAid,
termactive = x.TermActive,
vid = x.Vid,
fvo = x.FVO,
eterm = x.ETerm,
edef = x.EDef,
buse = x.BUse,
bterm = x.BTerm,
idcat = x.TermCat,
items = x.TermCategory1.IDCat,
catname = x.TermCategory1.TermCategory1
});
return Json(collection, JsonRequestBehavior.AllowGet);
Now inside the success callback the e parameter already represents an array of objects that were parsed. You don't need to call any eval. Directly access the elements (by index) and then the properties:
success: function (e) {
var txt = e[0].mvo;
},
you could also loop through the elements:
success: function (e) {
for (var i = 0; i < e.length; i++) {
var element = e[i];
alert(element.idterm);
}
},
