[TUniTreeNode.data]

You wrote: "Yes, it will be available on the server side"

Did you mean "Yes, it will be available on the client side"?

 

This would be fine  ,

but there is no need to hurry, I found a very simple solution (rather a hack):

 

I put the anchor hidden in the text property:

    Nd := NavTree.Items.Add(nil, '<span "' + sAnchor + '">' + sText + '</span>');

 

and then I can get it like so:

NavTree.ClientEvents.ExtEvents.Values['itemclick'] := 'function itemclick(sender, record, item, index, e, eOpts) {' +
      'var iPos = record.data.text.indexOf(">") - 1,' +
      '    anchor = record.data.text.substring(7, iPos),' +
      '    elTo = ' + UniURLFrame1.JSName + '.iframe.contentWindow.document.getElementById(anchor);' +
      'if (elTo) {' +
      '  ' + UniURLFrame1.JSName + '.iframe.contentWindow.document.scrollingElement.scrollTop = elTo.offsetTop - 5;' +
      '}' +
   '}';

[TUniTreeNode.data]

well, something is not working with this solution, I get the alert:

"Cannot read property 'data' of null"

 

when I set a breakpoint at

    O93.store.getNodeById(1).data._ID = 1;

and check in the console

    O93.store.getNodeById(1)

the result is null

 

after closing the alert the page is not visible, but when I then check again the console it gives me:

   constructor {$observableInitialized: true, hasListeners: j, eventedBeforeEventNames: {…}, events: {…}, initConfig: ƒ, …}

 

obviously the object does not exist at load-time yet

 

any Ideas?

[TUniTreeNode.data]

Hi,

is it possible to access the data of a UniTreeNode in javascript on the page?

I could not figure out how to do this.

Sencha treenode also has a data-property which can be accessed, but this is obviously not the same.

 

I added a value to a UniTreeNode like so:

 

type

  TNodeInfo = class(TObject)

    ID: Integer;

    scrollTo: String;

  end;

 

procedure addNode(NavTree: TUniTreeView; ID: Integer; sText, sAnchor: String);

var Nd: TUniTreeNode;

      Ni: TNodeInfo;

begin

       Ni := TNodeInfo.Create;

       Ni.ID := ID;

       Ni.scrollTo := sAnchor;

 

       Nd := NavTree.Items.Add(nil, sText);

       Nd.Data := Ni;

end;

 

In ExtEvents "itemclick" I can access record.data, but my added ID and scrollTo - properties are not available.

 

Thanks for help.

[Scrolling in TUniURLFrame]

Yes, this works from outside the frame!

 

From inside the frame it would be (added to the HTML at UniForm.Create):

'    parent.' + UniURLFrame1.JSName + '.iframe.contentWindow.document.scrollingElement.scrollTop = 0;'

or

'    parent.' + UniURLFrame1.JSName + '.iframe.contentWindow.document.scrollingElement.scrollTop = elTo.offsetParent';'

where elTo is the element to scroll to.

 

with javascript from outside the frame (f.i. from Ext ClientEvent, added to the ClientEvent at UniForm.Create):

'   var elTo = ' + UniURLFrame1.JSName + '.iframe.contentWindow.document.getElementById("some_ID");' +

'   if (elTo) {' +

'      UniURLFrame1.JSName + '.iframe.contentWindow.document.scrollingElement.scrollTop = elTo.offsetTop;' +

'   }'

 

Excellent support!

Thanks a lot!

[The Callout extension]

Demo looks great!

 

How do I add this file to the project?

I put it in:

   C:\Program Files (x86)\FMSoft\Framework\uniGUI\ext-4.2.5.1763\examples\ux\callout

but it does not work...

 

What am I doing wrong?

Any ideas?

[TUniURLFrame: how to fire OnAjaxEvent]

in MainForm there is only one UniURLFrame, then:

 

procedure TMainForm.UniFormCreate(Sender: TObject);

begin

    UniURLFrame1.HTML.Text := 

        '<script type="text/javascript">' +

        '   document.addEventListener("click", function(e) { ' +

        '       parent.ajaxRequest(' + UniURLFrame1.JSName + ', "ClickEvent", [ "param0=a", "param1=b" ]);' +

        '   })' +

        '</script>' +

        '<br>' +

        'click here' +

        '<br>';

end;

 

// this is never called:

procedure TMainForm.UniURLFrame1AjaxEvent(Sender: TComponent; EventName: string; Params: TUniStrings);

begin

    ShowMessage(Params.Values['param0'] + ' - ' + Params.Values['param1']);

end;

[TUniURLFrame: how to fire OnAjaxEvent]

Hi,

I cannot figure out how to fire the OnAjaxEvent from JS-code within the loaded page.

ajaxRequest can be called with "parent.ajaxRequest", but I cannot determine the first parameter "sender"

 

I tried:

  - parent.ajaxRequest(this, "ClickEvent", [ "param0=a", "param1=b" ]);

  - parent.ajaxRequest(O3C, "ClickEvent", [ "param0=a", "param1=b" ]);  // where "O3C" is the JS-name of the UniURLFrame (added via code on startup)

  - tried to get a reference to the UniURLFrame-control with:

      - var x = parent.getElementById("O3C");       // x is null

      - var x = parent.getElementById("O3C_id");  // x is null

nothing works.

 

Can anybody help please?

best regards

[Component sources in uniGUI Pro]

Well at least I would have to know when a link is clicked (navigate to another page).

But also mouseover and mouseout would be helpful.

 

Another possiblity would be to have an event that fires when a javascript function is executed from within the page.

This would be more generic then...

[Component sources in uniGUI Pro]

Hi, 

I need some more events with the UniURLFrame-component - is it possible to enhance this component when I buy the pro-version with sources?

Actually I would like to test this before ordering...

[UniURLFrame: Trigger some action when clicking a link]

Hi all,

 

I'm using a UniURLFrame in a TabSheet and want to add another TabSheet to the PageControl when clicking a link in the HTML-document.

How can this be done?

 

The link can call a javascript function (onclick="parent.addTabSheet('new Tabsheet')"), but I found no way to implement this function somewhere.

Is this possibel at all?

 

Thanks a lot for help.
