I've found examples of have multiple handlers on a page and the associated naming convention (ie OnPostXXX) and 'asp-post-hanlder' tag helper. But how can I call one of these methods from an AJAX call.
I have an older example with a typical MVC view and controller but how does this work with a Razor Page?
For example if I take the base application and modify the About.cshtml page to the following:
@page
@model AboutModel
@{
ViewData["Title"] = "About";
}
<h2>@ViewData["Title"]</h2>
<h3>@Model.Message</h3>
<input type="button" value="Ajax test" class="btn btn-default" onclick="ajaxTest();" />
@section Scripts {
<script type="text/javascript">
function ajaxTest() {
console.log("Entered method");
$.ajax({
type: "POST",
url: '/About', // <-- Where should this point?
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status, errorThrown) {
var err = "Status: " + status + " " + errorThrown;
console.log(err);
}
}).done(function (data) {
console.log(data.result);
})
}
</script>
}
And on the model page About.cshtml.cs
public class AboutModel : PageModel
{
public string Message { get; set; }
public void OnGet()
{
Message = "Your application description page.";
}
public IActionResult OnPost() {
//throw new Exception("stop");
return new JsonResult("");
}
}
The OnPost is not called from the Ajax call.
