callback param if there was space, it would change to + sign.

[AMIT]

I use the following code.

 

procedure TUniForm1.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'mycallback' then
  begin
    UniMainModule.FirstName := Params.Values['firstname'];
    UniMainModule.LastName := Params.Values['lastname'];
    if Params.Values['RES']='OK' then
      ModalResult:=mrOK
    else if Params.Values['RES']='CANCEL' then
      ModalResult:=mrCancel
  end;
end;

 

on HTML page if I type string into firstname input box, such as "AB CD", but the params.Values['firstname'] became "AB+CD".  

PS. I tested the demos "\Demos\Desktop\HTTP Post Callback - URLFrame - Auto Target", the same problem found.  How to fix this problem?     Please help.

Hi,

 

Can you try this approach?!:

 

 

 

<form name="input" action="{URL_CALLBACK}" method="POST" onsubmit="_firstname.value = encodeURIComponent(firstname.value); _lastname.value = encodeURIComponent(lastname.value); ">

<div style="padding:10;background-color:#eee;color:#0000CC">
<br/>
<br/>
<br/>
<br/>

First name: <input type="text" name="firstname" value ="Name"><br>
Last name: <input type="text" name="lastname" value="Last +Name">

<input type="hidden" name="_firstname">
<input type="hidden" name="_lastname">

<br/>
<br/>

<input type="submit" value="Submit">

<a href="{CANCEL_URL}">
  <input type="button" value="Cancel">
</a>
<br/>
<br/>
<br/>
<br/>

</div >
</form>

uses ... HTTPApp;

procedure TUniForm1.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'mycallback' then
  begin
    UniMainModule.FirstName := UTF8Decode(HTTPDecode(Params.Values['_firstname']));
    UniMainModule.LastName := UTF8Decode(HTTPDecode(Params.Values['_lastname']));
    if Params.Values['RES']='OK' then
      ModalResult:=mrOK
    else if Params.Values['RES']='CANCEL' then
      ModalResult:=mrCancel
  end;
end;

 

 

 

Best regards.

Thank you.   It's work correctly.     Anyway I wonder why the Params.Values change the space to +.      Why do we have to use UTF8Decode and HTTPDecode function to correct this?
