Calling a server side function from HTMLFrame

[Guest]

Message from: "fbarley"

 

I am using HTML Frame with great success in testing. Now I need to hook

up some server side logic to the user inputs in the HTMLFrame.

 

How do I set up a Ext.Ajax.request({url:"mydll/HandleEvent"... on the

client and server side to handle HTMLFrame coordination? Or is there a

better way?

.

Interaction between ClientSide JavaScript code and server handlers is not

implemented yet. It is planned to be implemented in one of the 0.8x

releases. That said, you can use JS code to call one of the "existing" AJAX

handlers.

Can you give us a example of this?

Consider you have a UniButton1 on form and it has a click event.

 

In UniHTMLFrame BeforeScript property:

 

function AjaxSuccess(response){

try{

eval(response.responseText);

}

catch(err){

AjaxError(err.message+"

"+response.responseText);

}

};

 

function buttonClick(Btn) {

=

Ext.Ajax.request({url:"/HandleEvent",params:"Ajax=3D1&Ajax=3D1&IsEvent=3D=

1&Obj=3D"+

=

Btn.nm+"&Evt=3Dclick&This=3D"+Btn.nm+_gv_(O0),success:AjaxSuccess,failure=

:{},obj:Btn});

}; =20

 

In Form OnShow event:

 

procedure TMainForm.UniFormShow(Sender: TObject);

begin

if WebMode then

begin

UniHTMLFrame1.HTML.Text:=3D'

id=3D"button1"'+

' =

onclick=3D"buttonClick('+TUniExtButton(UniButton1).ExtControl.JSName+')" =

value=3D"HTML Button" />';

end;

end;

 

Pressing HTML button will call UniButton1 event.

UniSession.AddJS('$.ajax({'
    + 'url: "' + UniSession.CallbackUrl('$.ajax', self, []) + '",'
    + 'type: "POST",'
    + 'data: {username:"g", abc:123},'
    + 'dataType: "text",'
    + 'success: function(data){'
    + '  alert("OK！"+data);'
    + '  }'
    + '});');
procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;Params: TStrings);
begin
if EventName = '$.ajax' then
  begin
    UniEdit1.Text := 'AAAAAAA';    //Execution is not successful（Show no change）。  showmessage(UniEdit1.Text);（Display results correctly）         This is why?
    UniSession.AResponse.ContentText := '{"success":true,"manager":[{"name":"xxx","userId":"222"},{"name":"yyy","userId":"333"}]}';
  end;
end;

unisession.AddJS('ajaxRequest(MainForm.window,"ajaxRequest",[]);');
procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;Params: TStrings);
begin
if EventName = 'ajaxRequest' then
  begin
    UniEdit1.Text := 'AAAAAA';     //Execution is successful（Show change）
    UniSession.Response := 'Ext.Msg.alert("","ok！");';
  end;
