How to parse JsonResult object from controller in MVC? – Asp.net

I am trying to learn asp.net. I am making a demo website in which there would be an admin panel. The admin would update the Daily Messages which will get reflected in the main homepage. I am using MVC.
I have created the table in database as

create table DailyMsg(Sno int primary key, msg varchar(max));

This is my controller

public class DailyMsgsController : Controller
    {
        private amenEntities db = new amenEntities();

        // GET: DailyMsgs
        public ActionResult Index()
        {
            return Json(db.DailyMsgs.ToList(),JsonRequestBehavior.AllowGet);
        }
}

On running the following URL, I am successfully able to see the data in JSON format.

https://localhost:44329/DailyMsgs

[{"Sno":1,"msg":"Hi!"}]

Now, I am stuck. I know that I would have to add another class for Data Access Layer, but I am confused as how should I parse this data and print it to the main HTML page.

From my research on the internet, I have found out that I might have to use JQuery. So, I wrote the following(with what I could understand from the internet as I am not familiar with JQuery) –

$.ajax({
    url: "/DailyMsgs/Index",
    type: "GET",
    success: function (data) {
        $("#div1").html(data);    
    }
});

This, of course, is not working and I can’t see anything on my webpage.

My Homepage.html

<body>
    <div id="div1"><h2>Let jQuery AJAX Change This Text</h2></div>
</body>
</html>
<script src="../Scripts/jquery-1.8.0.min.js"></script>
<script src="../Scripts/bootstrap.min.js"></script>
<link href="../Content/bootstrap.css" rel="stylesheet" />
<script src="../JQuery/DailyMsgsJQ.js"></script>

All I want is to read and parse msg from JSON and display it on webpage.

Could you guide me as how should I proceed or is there any other way to achieve the purpose? Thanks a lot!

    Your <script> tags are outside your <html> tag. That means the scripts are probably not even executed, or not loaded in the correct order. You want jQuery and Bootstrap to be loaded first, so put them in the <head>. Put your custom script just before the closing </body>, so it is loaded last.

    Try this

    $.ajax({
    url: "/DailyMsgs/Index",
    type: "GET",
    success: function (data) {
        $.each(data, function (index, element) {
            $("#div1").append(element.msg);    
        });
    }
});

    If you still have error please get console.log(data); and send for me.
