In javascript I have a function that returns ID.
I want to read this value from HTML javascript and display it on the Label.
procedure TMainForm.IWAppFormCreate(Sender: TObject);
begin
AddToInitProc('function GetId() { return 5; }');
end;
procedure TMainForm.IWAppFormShow(Sender: TObject);
begin
IWLabel1.Caption:= Here This ID from function GetId -> 5
end;

Howdy All,
One of my competitors overlays the current web page with their web application and any attempt to leave the page (back button, entering a new URL, etc) pops up a dialog asking if you are sure.
Any idea on how to implement such a feature? Even if the user tries to change the URL?
Most of the grievances I get from my customers is because their customers use the back button, etc and screw up the web reservation process.
Thanks,
Shane

Hello,
I am trying to install IW 15.0.24 under Delphi 10.3.1.
The installation went well but I Don't find any IW tab and components under the components palette.
The path in library is well defined.
Any advice about how to get the components and wizards in my IDE?
Thank you,
Davide

| IdHTTP Post problem |

I am trying to post weather data to the OpenWeatherMap API server.
They use a RESTful server (API 3.0).
The documentation on this is totally incomplete.
Using a third-party program called 'ARC' and a lot of research, I discovered that in addition to adding the KEY to the URL, it is also required that *before* the HTTP Request the same KEY is send, which in this ARC program is called an 'Action', with a 'Name' and a 'value'.
In another application reference on the Internet the same name+value where added in what was called the 'Params' of this application.
The only Params I have been able to find in the IdHTTP Client is here:
IdHTTP1.Request.Authentication.Params.AddValue('appid',APIKey);
But this cannot be done because the 'Authentication' is not created.
And when I try to create it manually, I get a
[dcc32 Warning] Unit1.pas(224): W1020 Constructing instance of 'TIdAuthentication' containing abstract method 'TIdAuthentication.DoNext'
I am not even sure if this is the right location for this 'name' + 'Key'.
The OpenWeatherMap API does not do any negotiation; When the HTTP Post is not excactly correct, it just gives a '400' and disconnects.
OnAuthorisation and OnSelectAuthorisation are never called.
How am I to add these values to the HTTP Post, *before* the body containing JSON data is send?

| Advice about where put a code to websocket |

Hi,
I have many iw forms, all inherited from a standard iwform(TIWFormStd).
I have a MasterTemplate html to all my IWForms.
I have my websocket server component in servercontroller module(I don´t know if this is the better place)
I need the websocket client available in all forms, because my app has a chat to users.
In that MasterTemplate, I have the next script code to connect to websocket server:
Code: <script>
function wschat()
{
if (!ws || ws.state()!='open'){
ws = new sgcWebSocket('ws://127.0.0.1:5414/auth/url/admin/1234');
}
ws.on('open', function(evt){
console.log(ws.state())
});
ws.on('message', function(evt){
console.log(evt.message)
})
}
wschat()
</script>
My problem is that when I open a new iwform, I allways release the old iwform. As the old form is released, the websocket connection in the frontend is destroyed as well and recreated when the new IWForm is active.
I´d like to know some suggestions about where I can put the websocket client code to avoid it.
Regards, Luiz

| IdDateTimeStamp gives strange result |

I might have missed something, but tried a very simple code:
procedure TForm1.Button1Click(Sender: TObject);
begin
IdDateTimeStamp1.SetFromTDateTime(Now);
memo1.lines.add(DateTimeToStr(Now));
memo1.lines.add(IdDateTimeStamp1.AsISO8601Calendar);
end;
and got the result:
9-7-19 12:06:56
2020-8-10T12:06:56,
i.e. the Year, the Month and the Day are all +1 compared to the real one. I tried other dates and always this offset.
Any idea?
I use Debian 9, Gnome 3.22.2, Lazarus 2.0.2., FPC 3.0.4, on 64 bit.
