Hi everyone. I would like to share with you some code. It consists of three interrelated Tiddlers that:
1. Store and display Geo-position. 2. Prompt the user for changes, if she/he decides to. 3. Fill some default value upon a change request, if the value is empty. Now this is simple to accomplish especially using JavaScript, BUT... I happened to notice that the <$reveal> <http://tiddlywiki.com/#RevealWidget> widget can be used to conditionally trigger ActionWidgets <http://tiddlywiki.com/#ActionWidgets>. Here are the contents of the Tiddlers. Note that we only need to - transclude *{{:/_template/geo-button}}* in any Tiddler as interface, and - reference the Geo-position by *{{**$:/_template/geo!!_position}}* tags: title: $:/_template/geo-button <$set name="thepos" value="51.5007, -0.1246"> <$button> <$action-sendmessage $message="tm-modal" $param="$:/_template/geo-prompt"/> <$reveal type="match" state="$:/_template/geo!!_position" text=""> <$action-setfield $tiddler="$:/_template/geo" $field="_position" $value=<< thepos>>/> </$reveal> <$reveal type="match" state="$:/_template/geo!!_position" text=" "> <$action-setfield $tiddler="$:/_template/geo" $field="_position" $value=<< thepos>>/> </$reveal> {{$:/_template/geo}} </$button> </$set> tags: title: $:/_template/geo-prompt ! {{$:/_template/geo!!_caption}} <$edit-text tiddler="$:/_template/geo" field="_position" placeholder="51.5007, -0.1246" class="tc-edit-texteditor" focus="true"/> tags: title: $:/_template/geo <font size=3>''{{!!_caption}}'' <font color= #BD1745>{{!!_position}}</font></font> I look forward to learning from your feedback. I apologize if this is trivial or a mere repetition, but to me it was new and non-trivial. Best, Mehdi -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
