dom-events

问题 I was wondering if in chrome code we have some better way to detect when the user selects/highlights something in the current page than listening for keyup / mouseup and checking window.getSelection() . Any ideas? edit: Actually, what I'm trying to do is simply preventing the user from selecting any text at all in the contentDocument. Something that accomplishes this will be fine as well. (The idea behind getting the selection event was just to preventDefault() or otherwise getSelection()

问题 There are events called 'onkeydown' and 'onkeyup' in Javascript. Can anyone please suggest the python equivalent of it? 回答1: Without any external library, python can't provide GUI features, such as events handling. Listening to an event such onkeydown or onkeyup is thus impossible with the python sdl. If you really want to react to these events, you must use an external library providing event-driven operations, such as the Qt binding PyQt, the TKinter module, or other libraries. 来源： https:/

问题 I want the user to download a PDF file after submitting a simple Contact Form 7 in Wordpress. I see that the on_sent_ok is deprecated and won't be allowed by the end of 2017 and should be replaced by DOM Events. I am having issues achieving this with the following code: .htaccess file: <FilesMatch "\.(?i:pdf)$"> ForceType application/octet-stream Header set Content-Disposition attachment </FilesMatch> functions.php: function mycustom_wp_footer() { ?> <script type="text/javascript"> document

问题 I added addEventListener click, drop, dragover on new child created div element. On the new created div element the click works, but the drop and the dragover do not work. How can every new child-div get drop-drag-div? I can not figure out where I made a mistake. Is there any solution? add Event Listener ('click') - work, add Event Listener ('drop') - do not work, add Event Listener ('dragover') - do not work. <style> #divs{ width: 450px; height: 70px; margin: 10px; padding: 10px; background

问题 I'm trying to listen to "oninput" event, but something is wrong with Opera: document.getElementById("i1").oninput = function(){ console.log("inputting"); }; document.getElementById("i1").addEventListener("input", function(){ console.log("inputting"); }); The first one works, but the second one doesn't work....it this a bug of opera? Fiddle: http://jsfiddle.net/nn2zS/ 回答1: OK, I figured out this myself, addEventListener has a 3rd parameter, it can be ignored in Chrome but not other browsers.

问题 I'm writing an extension that checks every document a user views on certain data structures, does some back-end server calls and displays the results as a dialog.The problem is starting and continuing the sequence properly with event listeners. My actual idea is: Load: function() { var Listener = function(){ Fabogore.Start();}; var ListenerTab = window.gBrowser.selectedTab; ListenerTab.addEventListener("load",Listener,true); } (...) ListenerTab.removeEventListener("load", Listener, true);

问题 For many reasons, I have to open up XUL in a tab, instead of using a standard window. I wish to send custom events to this tab, and here's how my code looks like : myextension.js : .. var pTab = window.gBrowser.loadOneTab("chrome://myextension/path/options.xul", {inBackground: false}); var pWin = window; var event = new pWin.CustomEvent("prefwindow-event"); pWin.dispatchEvent(event); .. options.xul code: window.addEventListener("load", init, false); window.addEventListener("prefwindow-event",
