public class HomeController : Controller { public ActionResult Index() { return View(); } public ActionResult UpdateLabelText(string selectedValue) { string updatedText = "Updated text based on " + selectedValue; return Content(updatedText); } } @{ ViewBag.Title = "Dynamic Label Text Example"; } Dynamic Label Text Example @Html.DropDownList("dropdown", new SelectList(new[] { "Option 1", "Option 2", "Option 3" })) $(document).ready(function () { $("#dropdown").change(function () { var selectedValue = $(this).val(); $.ajax({ type: "GET", url: "@Url.Action("UpdateLabelText", "Home")", data: { selectedValue: selectedValue }, success: function (data) { $("#label1").text(data); // Update the label's text } }); }); });
