How to post JSON string as a string in jQuery AJAX

Hello friend, In this short post I will share how to post JSON model as a string to the action method of the controller in MVC using jQuery Ajax.

Suppose you wanted to save user preference as JSON string in one of the column of your table in database, then you can write a action method like following.

[HttpPost]
public void SaveSetup(string jsonString)
{
        //code to save setting in databse
}

And you need to write code like following on some button click to post your JSON model to above action method.

var jsonModel = "your json model";

$.ajax({
            type: 'POST',
            data: JSON.stringify({ jsonString: JSON.stringify(jsonModel) }),
            contentType: "application/json; charset=utf-8",
            url: "/User/SaveSetup/",
            dataType: 'json', 
            success: function (data) {
                alert('saved');
            }
 });

That's it, with above code you can successfully post JSON model as string.
