// we won't do copy on select on text editor, otherwise you can't select and override text in the editor or text inputfunction checkIfElementIsEditor(element) { if (!element || !element.nodeName) return false; const isEditableElement = ['INPUT', 'TEXTAREA', 'BUTTON'].includes(element.nodeName); if (!isEditableElement) { if (!element.className || !element.className.toLowerCase) return false; } const isTextEditor = element.className.toLowerCase().includes('codemirror'); return isEditableElement || isTextEditor; }// if we start selection on editor, we prevent the following execution of this scriptlet copyOnSelectPreventNextCopy = false;document.addEventListener('mousedown', function onMouseDown() { const elementsUnderMouse = document.querySelectorAll(':hover'); if (!elementsUnderMouse || Array.from(elementsUnderMouse).some(checkIfElementIsEditor)) { copyOnSelectPreventNextCopy = true; } });// Copy on select, copy document selection when mouse button is updocument.addEventListener('mouseup', function onMouseUp() { const elementsUnderMouse = document.querySelectorAll(':hover'); if ( copyOnSelectPreventNextCopy || !elementsUnderMouse || Array.from(elementsUnderMouse).some(checkIfElementIsEditor) ) { copyOnSelectPreventNextCopy = false; return; } document.execCommand('copy'); }); 在 2020年4月11日星期六 UTC+8下午4:26:04,Eric Shulman写道: > > On Saturday, April 11, 2020 at 12:08:15 AM UTC-7, Lin Onetwo wrote: >> >> I found $:/tags/StartupAction/Browser will only execute tiddlywi >> actions, but can't execute javascript. >> But I have following JS want to execute: >> What could I do? >> I'm currently using WebcataLog to inject Userscript before wiki loading >> > > 1) added <script> ... </script> around your code > 2) tag the tiddler with $:/tags/RawMarkup > 3) save-and-reload your document > > What this does is to add the content of the tagged tiddler to the bottom > of the <head> section of the document. > This allows your JS code to be invoked as soon as the document is loaded, > even before the TWCore wiki is initialized > > (see https://tiddlywiki.com/#SystemTag%3A%20%24%3A%2Ftags%2FRawMarkup) > > enjoy, > -e > > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
