  • how to attach window.close to cntrl+w keypress event in a xul window?

    - by Erik Vold
    I have a XUL window, and I want the cntrl+w hotkey to close the window, but when I attach: window.addEventListener("keypress", function(ev) { GM_log("onkeypress handler: \n" + "keyCode property: " + ev.keyCode + "\n" + "which property: " + ev.which + "\n" + "charCode property: " + ev.charCode + "\n" + "Character Key Pressed: " + String.fromCharCode(ev.charCode) + "\n"); }, true); to the page, it treats pressing 'w' and 'cntrl+w' the same, charCode 119.. how can I determine that cntrl+w was pressed so that I may window.close() ?

  • Computed column should result to string

    - by strakastroukas
    Here is a snap of my database. Both col1 and col2 are declared as int. My ComputedColumn currently adds the Columns 1 and 2, as follows... col1 col2 ComputedColumn 1 2 3 4 1 5 Instead of this, my ComputedColumn should join the columns 1 and 2 (includimg the '-' character in the middle) as follows... col1 col2 ComputedColumn 1 2 1-2 4 1 4-1 So, what is the correct syntax?

  • jQuery ajax multiline "script" response

    - by Rendrik
    I'm designing a template creation tool, which uses a jQuery Ajax request that posts parameters to a PHP file. The PHP does the actual generation of the template's HTML. // Send for processing. Expect JS back to execute. function generate() { $.ajax({ type: "POST", url: "generate.php", data: $('#genform :input').serialize(), dataType: "script", beforeSend: function() { $("#loading").html("<img src='images/loadbar.gif' />"); $("#loading") .dialog({ height: 80, width: 256, autoOpen: true, modal: true }); }, success: function(data) { $("#loading").dialog('close'); } }); } My trouble is that I have the ajax dataType: set to "script". Using this, the PHP file generates some jQuery dialogs for any errors which works nicely. However, after I generate the HTML, i'm having trouble passing it back. So I have probably 100 lines of generated HTML and javascript which i'd like to work with. In the PHP file, i've tried: echo('$("#result").html("'.$html.'");'); This does actually work if there are NO line breaks in $html. As soon as there are any line breaks, the Chrome debugger reports "gen.html:1 Uncaught SyntaxError: Unexpected token ILLEGAL". It's obvious that it's trying to eval the returned response headers, but is stopping at any line break. So, to be clear, when I pass $html back, if the contents are this: $html = "<div>hi there</div>"; It works fine (all of my error message dialogs are one line). But if it's: $html = "<div> hi there </div>"; It blows up. I'm really not sure how to get around this, or if there's a better way to go about it. It's important to me to keep the formatting so people can copy the HTML template. I may just break down and display the template file on the PHP page if I can't solve this, but I was really hoping to keep everything within the confines of the HTML page.

  • Python style: multiple-line conditions in IFs

    - by Eli Bendersky
    Hello, Sometimes I break long conditions in IFs to several lines. The most obvious way to do this is: if (cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Isn't very very appealing visually, because the action blends with the conditions. However, it is the natural way using correct Python indentation of 4 spaces. Edit: By the way, for the moment I'm using: if ( cond1 == 'val1' and cond2 == 'val2' and cond3 == 'val3' and cond4 == 'val4'): do_something Not very pretty, I know :-) Can you recommend an alternative way ?

  • Looking for a good Delphi unicode string library

    - by volvox
    Any suggestion for a good unicode string library for Delphi 2010? Such thing as class that would contain a collection of independent functions, basically an encapsulation of functions that manipulate strings (ex: Trimlike, Character removal, Positional, Sub-string, Compare, Informational, Case, Replacement, Manipulation functions etc. ). Thanks

  • A* algorithm works OK, but not perfectly. What's wrong?

    - by Bart van Heukelom
    This is my grid of nodes: I'm moving an object around on it using the A* pathfinding algorithm. It generally works OK, but it sometimes acts wrongly: When moving from 3 to 1, it correctly goes via 2. When going from 1 to 3 however, it goes via 4. When moving between 3 and 5, it goes via 4 in either direction instead of the shorter way via 6 What can be wrong? Here's my code (AS3): public static function getPath(from:Point, to:Point, grid:NodeGrid):PointLine { // get target node var target:NodeGridNode = grid.getClosestNodeObj(to.x, to.y); var backtrace:Map = new Map(); var openList:LinkedSet = new LinkedSet(); var closedList:LinkedSet = new LinkedSet(); // begin with first node openList.add(grid.getClosestNodeObj(from.x, from.y)); // start A* var curNode:NodeGridNode; while (openList.size != 0) { // pick a new current node if (openList.size == 1) { curNode = NodeGridNode(openList.first); } else { // find cheapest node in open list var minScore:Number = Number.MAX_VALUE; var minNext:NodeGridNode; openList.iterate(function(next:NodeGridNode, i:int):int { var score:Number = curNode.distanceTo(next) + next.distanceTo(target); if (score < minScore) { minScore = score; minNext = next; return LinkedSet.BREAK; } return 0; }); curNode = minNext; } // have not reached if (curNode == target) break; else { // move to closed openList.remove(curNode); closedList.add(curNode); // put connected nodes on open list for each (var adjNode:NodeGridNode in curNode.connects) { if (!openList.contains(adjNode) && !closedList.contains(adjNode)) { openList.add(adjNode); backtrace.put(adjNode, curNode); } } } } // make path var pathPoints:Vector.<Point> = new Vector.<Point>(); pathPoints.push(to); while(curNode != null) { pathPoints.unshift(curNode.location); curNode = backtrace.read(curNode); } pathPoints.unshift(from); return new PointLine(pathPoints); } NodeGridNode::distanceTo() public function distanceTo(o:NodeGridNode):Number { var dx:Number = location.x - o.location.x; var dy:Number = location.y - o.location.y; return Math.sqrt(dx*dx + dy*dy); }

  • Decode base64 data as array in Python

    - by skerit
    I'm using this handy Javascript function to decode a base64 string and get an array in return. This is the string: base64_decode_array('6gAAAOsAAADsAAAACAEAAAkBAAAKAQAAJgEAACcBAAAoAQAA') This is what's returned: 234,0,0,0,235,0,0,0,236,0,0,0,8,1,0,0,9,1,0,0,10,1,0,0,38,1,0,0,39,1,0,0,40,1,0,0 The problem is I don't really understand the javascript function: var base64chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'.split(""); var base64inv = {}; for (var i = 0; i < base64chars.length; i++) { base64inv[base64chars[i]] = i; } function base64_decode_array (s) { // remove/ignore any characters not in the base64 characters list // or the pad character -- particularly newlines s = s.replace(new RegExp('[^'+base64chars.join("")+'=]', 'g'), ""); // replace any incoming padding with a zero pad (the 'A' character is zero) var p = (s.charAt(s.length-1) == '=' ? (s.charAt(s.length-2) == '=' ? 'AA' : 'A') : ""); var r = []; s = s.substr(0, s.length - p.length) + p; // increment over the length of this encrypted string, four characters at a time for (var c = 0; c < s.length; c += 4) { // each of these four characters represents a 6-bit index in the base64 characters list // which, when concatenated, will give the 24-bit number for the original 3 characters var n = (base64inv[s.charAt(c)] << 18) + (base64inv[s.charAt(c+1)] << 12) + (base64inv[s.charAt(c+2)] << 6) + base64inv[s.charAt(c+3)]; // split the 24-bit number into the original three 8-bit (ASCII) characters r.push((n >>> 16) & 255); r.push((n >>> 8) & 255); r.push(n & 255); } // remove any zero pad that was added to make this a multiple of 24 bits return r; } What's the function of those "<<<" and "" characters. Or is there a function like this for Python?
