javascript - My json object turns out null and I can't see why -

So I went to the web exploring a way to send data from my JS to my controller, and it seems to be a good one Solution.

  function syncDB () {if (localStorage.length! = 0) {var data = viewLog (); (Var i = 0; i & lt; localStorage.length; i ++) {$. Ajax ({url: "/ lead / registerofflineinterries", type: "post", datatype: "jsan", data: json.stringify (data)}); }}  

}

This is sent to the following address:

  public operations registeroffline entries (string [] leads) { String [] splitLeads; For (int i = 0; i & lt; clue; height; i ++) {splitLeads = clue [i]. Clear (','); Var validFields = new list & lt; LeadFields & gt; (); Var field = new list & lt; LeadFields & gt; {New Leadfield () {Value = Split Leeds [0], Fields IID = 1}, New Leadfield () {Value = Partition Lith [1], Fields IID = 2}, New Leadfield () {Value = Split Leeds [2] ], Fields = 3}, New Leadfield () {value = Partition Leeds [3], Field IID = 4}, New Leadfield () {Value = Partition type [4], field IID = 5}}; Forkhaa (different types of fields where (V =>; (String.IsNullOrEmpty (v.Value))) {v.value = v.value.ToUpper (); ValidFields.Add (v); }} Return Redirect Action ("Index", "Home"); }  

Now, the code has not been read too much, because the problem in the ActionMethod parameter is implied. It's empty, and I do not understand that, when I use JS data elsewhere, I can read the data on it, but it does not work by sending it to the controller.

Thank you!

Edit: The object trying to look at the object is taken from the method that looks like

  function view log () {var localDbList = [localStorage .length];  DBList [i] = local storage [i];} Return local DBList;  

} / P>

I have a local storage for offline support and I am trying to assume the stored data here and save them on my server

you exact Has not posted the format that is in data , it must be before the stringing

  var leadsStrings = new array (); LeadsStrings.push ("string1"); LeadsStrings.push ("string2"); // etc var databobz = {leads: leadings}; Data: databobes function syncDB () {var data = new array (); If (localStorage.length! = 0) {for (var i = 0; i & lt; localStorage.length; i ++) {data.push (local storage [i]); } Var dataobject = {leads: data}; $ .ajax ({url: "/ leads / registeroffline entities", data: databases}); }}  

Do you mean it?
