modal window when delete a tiddler from tiddler view button

[Mohammad]

When you want to delete a tiddler via Tiddler view toolbar, delete button

a nice local (tm-modal) is appeared and says

 Do you wish to delete the tiddler "HelloThere"?

I want to know how I can duplicate this for other purpose!

I dont want to develop from scarctch and wish to use it for other purpose!

I think there is a difference between ActionDeleteTiddlerWidget and tm-delete-tiddler. Only the latter generates a confirmation dialogue.

$:/core/ui/Buttons/delete uses tm-delete-tiddler.

The confirmation message is in
$:/language/ConfirmDeleteTiddler

Thanks Watt!

I will take a look to see how TW implements it!

Hi Mohammad

That modal dialogue is a browser feature called “confirm()”:

https://developer.mozilla.org/en-US/docs/Web/API/Window/confirm

It presents a simple text based dialogue to the user with optional “OK” and “cancel” buttons. It’s unusual amongst web DOM features in that it pauses execution of the script until the user responds.

Making it available as a generic wikitext feature is tricky, however. For example, we could make a “tm-confirm” message. The easy part is to give it a parameter containing the message to be displayed. For the users response, one could imagine a parameter specifying the name of a tiddler to receive the text “ok” or “cancel” according to the response of the user.

The gotcha is that that updated tiddler value wouldn’t be available to any further actions in an action string; they would have been compiled with the previous value of that tiddler.

Making a <$action-confirm> widget instead of a message doesn’t help, sadly.

On the bright side, some people people consider the Window.confirm() to be a bad idea because of the way that it blocks access to the rest of the page. The alternative is to construct a non-modal confirmation system — for example, the “delete” button in advanced search “Filter” tab.

Best wishes

Watt!

I see the $:/core/ui/Buttons/delete uses tm-delete-tiddler

<$button message="tm-delete-tiddler" tooltip={{$:/language/Buttons/Delete/Hint}} aria-label={{$:/language/Buttons/Delete/Caption}} class=<<tv-config-toolbar-class>>>

<$list filter="[<tv-config-toolbar-icons>prefix[yes]]">

{{$:/core/images/delete-button}}

</$list>

<$list filter="[<tv-config-toolbar-text>prefix[yes]]">

<span class="tc-btn-text"><$text text={{$:/language/Buttons/Delete/Caption}}/></span>

</$list>

</$button>

One expect to see a call to tm-modal message and don't find it!

Many thanks Jeremy!

I tried to use this feature in my newly developed plugin Trashbin:https://kookma.github.io/TW-Trashbin/

but I decided to use the tm-notify!

For the other part e.g user interaction I use the same mechanism as you pointed out: the “delete” button in advanced search “Filter” tab.

I used this in "Empty Trashbin" button on the sidebar!

Thanks again!

Cheers

Mohammad
