asp.net mvc ajax post model

If model contain variable of class Class1 with properties Property1,Property2.
Submitted parameters must be named:
"Class1.Property1"
"Class1.Property2"

If model has property as List<Record> submitted values must be :
"Class1[0].Property1"
"Class1[0].Property2"
"Class1[1].Property1"
"Class1[1].Property2"
"Class1[2].Property1"
"Class1[2].Property2"

Here are samples of two functions that creates this values dynamically before submitting form.

     
//this function create parameters for sending them over AJAX 
function ConvertJSONIntoPostableHTML() { 
var params = { 
            param1 : 'myvalue', 
        }; 
 
if (Jsonrecord != null) { 
    for (var i = 0; i < Jsonrecord.length; i++) { 
        var rec = Jsonrecord[i]; 
        $.each(Object.keys(rec), function(j, value) { 
            params["Records[" + i + "]." + value] = rec[value]; 
        }); 
    } 
} 
 
return params; 
} 

        
 
//this function add parameters to form , then form can be submitted  
function SelectedNodes(frm) { 
            $(".tslct").remove(); 
            var i = 0; 
                $.each(myJsonCollection, function () { 
                                var obj = "Nodes[" + i + "]."; 
                                addElem(frm, obj + "Id", this.Id); 
                                addElem(frm, obj + "Value", this.Type); 
                                i++; 
                } 
        ); 
}
