Do I need to build these files? If so what should be inside these ACTION files?
Here you can see the errors that are created for me:
Thanks for understanding (I'm pretty new to the language so help really got needed).
You have to implement and/or connect to an existing CAPTCHA server that would provide your code with images and solutions. Your localhost:8080 web server apparently does not know how to react on your CAPTCHA requests thus returns a 404.

I am trying SSE just to see how they work but I can't understand why this code is not working. I am getting a client error.
In my asp controller:
public class Example {
public Example() {
X = "12";
Y = 5;
}
public string X { get; set; }
public int Y { get; set; }
}
public IActionResult Index() {
return View();
}
public async Task Messaggio() {
Response.Headers.Add("Content-Type", "text/event-stream");
var msg = System.Text.Json.JsonSerializer.Serialize(new Example());
var bytes = Encoding.ASCII.GetBytes(msg);
await Response.Body.WriteAsync(bytes, 0, bytes.Length);
await Response.Body.FlushAsync();
Response.Body.Close();
}
Client-side generated html:
<html><head>
<script src="https://code.jquery.com/jquery-3.5.0.min.js"></script>
</head>
<body>
ciaoooo
<div id="Messaggio"></div>
<script>
source = new EventSource('/Home/Messaggio');
source.onopen = function (ddd) {
console.log("aperta");
};
source.onerror = function (ddd) {
console.log("errore");
console.log(ddd.data);
source.close();
};
source.onmessage = function (ddd) {
$("#Messaggio").text(ddd.data);
console.log(ddd.data);
};
</script>
</body>
</html>
Browser console output:
aperta
errore
undefined
routes are ok because if I request /home/messaggio it does work, I get the Json file
Thanks to anyone who can help me.
You did not add the "data" attribute before the returned "msg", so you cannot get the ddd.data value in js.
Modify the Messaggio action as follows:
public async Task Messaggio()
{
Response.Headers.Add("Content-Type", "text/event-stream");
var msg = System.Text.Json.JsonSerializer.Serialize(new Example());
var bytes = Encoding.ASCII.GetBytes($"data: {msg}\n\n");
await Response.Body.WriteAsync(bytes, 0, bytes.Length);
await HttpContext.Response.Body.FlushAsync();
Response.Body.Close();
}
Here is the result:
I am trying to call a Razor Page Handler using JQuery AJAX. Here is the sample code.
<script type="text/javascript">
$(document).ready(function () {
$("#SectionId").change(function () {
var options = {};
options.url = $(location).attr('href') + "/?SectionId=" + $("#SectionId").val() + "?handler=SelectByID";
options.type = "GET";
options.dataType = "json";
options.success = function (data) {
};
options.error = function () {
$("#msg").html("Error while making Ajax call!" + options.error.val);
};
$.ajax(options);
});
});
</script>
Razor Page cs code:
public class CreateModel : PageModel
{
private readonly ApplicationDbContext _context;
private readonly UserManager<ApplicationUser> _userManager;
private Task<ApplicationUser> GetCurrentUserAsync() => _userManager.GetUserAsync(HttpContext.User);
[BindProperty]
public FileRecord FileRecord { get; set; }
public List<SelectListItem> UserList { get; set; }
public string SelectedSectionId { get; set; }
public CreateModel(ApplicationDbContext context, UserManager<ApplicationUser> userManager)
{
_context = context;
_userManager = userManager;
}
public IActionResult OnGetSelectByID(string SectionId)
{
return null;

List<ApplicationUser> Users = await _context.Users.ToListAsync();
foreach (var item in Users)

The Issue is am not getting a call to Razor Page Handler defined above. If i skip the SectionId parameter passed-in & call only the handler. it is working fine. but it is not working when parameter is sent to the handler, default OnGet() is being called.
Help plz.
You don't need to append your handler parameter
options.url = $(location).attr('href') + "/?SectionId=" + $("#SectionId").val();
You also need to decorate the method with the HttpGet attribute
[HttpGet("GetSelectByID")]
public IActionResult OnGetSelectByID(string SectionId)
{
return null;
}
Then your URL to call this method needs to be
http://localhost:xxxx/FileMovement/Create/GetSelectByID?SectionId=yyy
When you have more than one GET defined on a controller you must tag the additional GET methods with the HttpGet attribute and add a string to define the name of that method.
Finally i was able to solve the issue.
<script type="text/javascript">
$(document).ready(function () {
$("#SectionId").change(function () {
var options = {};
options.url = $(location).attr('href') + "?handler=SelectByID" + "&SectionId=" + $("#SectionId").val();;
options.type = "GET";
options.dataType = "json";
options.success = function (data) {
};
options.error = function (data) {
$("#msg").html("Error while making Ajax call!" + data.error.val);
};
$.ajax(options);
});
});
Everything was right except i have to use "&" in "&SectionId="
I have used HybridWebView from XLabs to build a HybridWebView that can communicate with C# code. I have build custom renderers to do this. In simple terms I have:
iOS
public class HybridWebViewRenderer : ViewRenderer<HybridWebView, WKWebView>, IWKScriptMessageHandler
{
const string JavaScriptFunctionTemplate = "function {0}(){{window.webkit.messageHandlers.invokeAction.postMessage('{0}|' + JSON.stringify(arguments));}}";
protected override void OnElementChanged(ElementChangedEventArgs<HybridWebView> e)
{
base.OnElementChanged(e);
if (Control == null)
{
userController = new WKUserContentController();
foreach (var f in Element.RegisteredFunctions.Where(ff => !ff.IsInjected))
{
var script = new WKUserScript(new NSString(string.Format(JavaScriptFunctionTemplate, f.Name)), WKUserScriptInjectionTime.AtDocumentEnd, false);
userController.AddUserScript(script);
f.Injected();
}
userController.AddScriptMessageHandler(this, "invokeAction");
var config = new WKWebViewConfiguration { UserContentController = userController };
var webView = new WKWebView(Frame, config)
{
NavigationDelegate = new CustomWKNavigationDelegate(this.Element)
};
SetNativeControl(webView);
}
if (e.OldElement != null)
{
userController.RemoveAllUserScripts();
userController.RemoveScriptMessageHandler("invokeAction");
var hybridWebView = e.OldElement as HybridWebView;
hybridWebView.Cleanup();
}
if (e.NewElement != null)
{
Load(Element.Uri);
}
}
public void DidReceiveScriptMessage(WKUserContentController userContentController, WKScriptMessage message)
{
var bits = message.Body.ToString().Split('|');
if (bits.Count() == 2)
{
var result = Element.InvokeFunction(bits[0], bits[1]);
//How do I return result back to Javascript function?
}
}
the InvokeFunction method returns a value result which is a string.
How can I return this string result back to the javascript function which was injected?
Edit
Do I need to edit my JavaScriptFunctionTemplate I notice in the XLabs they have a similar template but append something to the end
Is there any reason why you couldn't simply 're-call' your function using the methods described here?
Their example:
void OnCallJavaScriptButtonClicked (object sender, EventArgs e)
{
...
int number = int.Parse (numberEntry.Text);
int end = int.Parse (stopEntry.Text);
webView.Eval (string.Format ("printMultiplicationTable({0}, {1})", number, end));
}
So yours would be something like:
const string JavaScriptFunctionTemplate = "function {0}(){{window.webkit.messageHandlers.invokeAction.postMessage('{0}|' + JSON.stringify(arguments));}}";
public void DidReceiveScriptMessage(WKUserContentController userContentController, WKScriptMessage message)
{
var bits = message.Body.ToString().Split('|');
if (bits.Count() == 2)
{
var result = Element.InvokeFunction(bits[0], bits[1]);
webView.Eval(string.Format ("JavaScriptFunctionTemplate({0})", result)); // or however your parameter structure is.
}
}
EDIT:
Just want to encorporate the LINK that the OP found as it looks to be a solid guide to the solution in Objective-C which is fairly straight forward to convert to Xamarin C#.
I have a WCF service being hosted locally and a website also being hosted locally. I make a GET ajax request for JSON data which I handle on success. I have a problem where in Chrome and Firefox it goes into the error block of the Ajax request.
<!--jQuery dependencies-->
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/themes/base/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

<script type="text/javascript" src="../../Library/JS/pqgrid.min.js"></script>
<script type="text/javascript">
var jqNew = $.noConflict(true);
</script>
Because of the complexity of the website, I am using two different versions of JQuery. The newer version has the alias of jqNew.
jqNew(document).ready(function () {
$($.ajax({
url: "http://wks52025:82/WcfDataService.svc/GetNotesFromView()?$format=json",
type: "GET",
datatype: "json",
async: false,
success: function (data, textStatus) {
alert(textStatus);
$.each(data.d, function (i, item) {
alert(i);
DataArray[i] = [];
DataArray[i][0] = item.NotesID;
DataArray[i][1] = item.NotesTitle;
DataArray[i][2] = item.NotesText;
DataArray[i][3] = item.ProfileName;
DataArray[i][4] = item.IsShared;
DataArray[i][5] = item.NameOfUser;
});
},
error: function (data, textStatus) {
alert(textStatus);
}
})).then(buildGrid(DataArray));
This is my request. It is synchronous because I want the data before I build my grid. It is a GET request because all I want is to retrieve data. I am not doing a cross-domain request because everything is happening locally, at least I think it's local because the website and service is localhost.

Anyone know why this doesn't work in firefox and chrome?
I'm doing a project in GWT to deploy in AppEngine and I'm getting a warning in Eclipse saying:
JavaScript parsing: Expected an identifier in JSNI
reference
Any ideas on what's causing this?
public void callFacebookAPI(String url) {
JsonpRequestBuilder requestBuilder = new JsonpRequestBuilder();
requestBuilder.requestObject(url, new AsyncCallback<FbUser>() {
public void onFailure(Throwable caught) {
System.out.println("FAIL" );
}
#Override
public void onSuccess(FbUser result) {
facebookUser = result;
System.out.println("Facebook name:" + facebookUser.getName());
}
});
}
private final native void doFbLoginFunction() /*-{
FB.login(function(response) {
if (response.authResponse) {
// connected
//return response.session;
var accessToken = response.accessToken;
var url = "http://graph.facebook.com/me?access_token=";
var facebookUrl = url + accessToken;
#com.google.gwt.smartpark.client.map.SmartPark::callFacebookAPI(Ljava/lang/String;Ljava/lang/
String;)(facebookUrl);
} else {
// cancelled
}
});
callFacebookAPI is not static so there must be something before the # in the reference in JSNI, e.g.
var that = this;
$wnd.FB.login($entry(function(response) {
// ...
that.#com.google.gwt.smartpark.client.map.SmartPack::callFacebookAPI(Ljava/lang/String;)(facebookUrl);
// ...
}));
Also, your callFacebookAPI takes a single argument, so the JSNI signature should have a single Ljava/lang/String;.
