  • How to get HTML from external contents with Jquery?

    - by André
    Hi, I have successfully achieved the task of getting an internal webpage to show on my HTML, like I show bellow. click here to see teste1.html $('#target').click(function() { $.get('teste1.html', function(data) { $('#result').html(data); alert('Load was performed.'); }); }); The main goal is to get an external webpage, but this is not working: $.get('http://www.google.com/index.html', function(data) { $('#result').html(data); alert('Load was performed.'); }); I need to get the HTML from an external webpage to read the tags and then output to Json. Some clues on how to achieve this(load external webpages with Jquery, or should I do it with PHP)? Best Regards.

  • Comparing two ISO8601 dates strings in PHP

    - by oompahloompah
    I need to compare (actually rank/sort) dates in a PHP script. The dates are ISO-8601 Date format i.e. YYYY-MM-DD I wrote a comparison function which splits the dates and compares by year/month/day. However, it seems this may be overkill and I could just as easily done a simple string comparison like: if ($date1 < $date2) // do something elseif( $date1 > $date2) //do something else else //do yet another thing Is my assumption about (ISO-8601) Date string comparison correct - i.e. can I get rid of my function (to save a few clock cycles on the server), or is it safer to explicity do the comparison in a custom function?

  • Visual C++/CLI "An unhandled exception of type 'System.StackOverflowException' occurred in"

    - by JennyWong
    Hi, I have a game I am making, it is giving me this message... "An unhandled exception of type 'System.StackOverflowException' occurred in game.exe" To explain...I have a 2D array with 9 different opening moves and I am getting a random number to use as the array reference to retrieve the details needed for a move... you may get the same move again - but that's illegal. the move may be illegal for other reasons too So to try and fix this, I am calling the function again from within the function. The error occurs very randomly Is this bad practise to call a function from within itself? What would be a better way to randomly row from a 2D array, AND if it isn't accept to get another one.... Or better still, how can I retrieve a random LEGAL move?

How can I remove it? downloadUrl("myfile.asp", function(data) { var xml = xmlParse(data); var markers = xml.documentElement.getElementsByTagName("marker"); var path = []; for (var i = 0; i < markers.length; i++) { var lat = parseFloat(markers[i].getAttribute("lat")); var lng = parseFloat(markers[i].getAttribute("lng")); var point = new google.maps.LatLng(lat,lng); path.push(point); }//finish loop var polyline = new google.maps.Polyline({ path: path, strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 2 }); polyline.setMap(map); }); //end download url I have tried it using the next function but I m not able to make it work. function removePath() { polyline.setMap(null) }

  • XML jQuery Problem

    - by Llamabomber
    This code for parsing my xml and appending via jquery seems to work great in every browser but Chrome (Mac only, the windows version of chrome works fine) and explorer. I'm not aware of any glaring issues in the code so I thought some fresh eyes might help. Anyone know what could be causing IE and Chrome on the mac to not append? <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $.ajax({ type: "GET", url: "sitenav.xml", dataType: "xml", success: parseXml }); function parseXml(xml) { $(xml).find("GoogleAnalytics").each(function() { $("li#google_analytics").append('<ul><li>' + $(this).find("NavHeader").text() + '</li></ul>'); }); } }); </script>

  • JSObject-like stuff in ActionScript 3?

    - by johncch
    I would like to ask if there is a liveconnect equivalent for ActionScript 3. I understand that there is the ExternalInterface class inside AS3 but it only supports calling a method by name. The really cool thing about Java and LiveConnect is that you can do something like function jsFunc(name) = { this.name = name; this.talk = function(){ alert('hello world my name is ' + this.name); } } javaapplet.function(new jsFunc("bob")); The above approaches pseudo code since I never tested it but I've seen it in action. In AS3, while I am able to pass in an instance of JavaScript "object" into AS, it is often converted into an ActionScript Object instance which does away with all the functions as far as I'm aware. I saw an implementation of JSInterface but I don't think it does specifically that. Is there any way to make OO like javascript work with ActionScript 3?

  • 1136: Incorrect number of arguments. Expected 0.? AS3 Flash Cs4 (Round 2)

    - by charmaine
    (I have asked this before but I dont think I was direct enough with my question and therefore it did not get resolved so here goes again!) I am working through a book called Foundation Actionscript 3.0 Animation, making things move. I am now on Chapter 9 - Collision Detection. On two lines of my code I get the 1135 error, letting me know that I have an incorrect number of arguments. I have highlighted the two areas in which this occurs with asterisks: package { import flash.display.Sprite; import flash.events.Event; public class Bubbles extends Sprite { private var balls:Array; private var numBalls:Number = 10; private var centerBall:Ball; private var bounce:Number = -1; private var spring:Number = 0.2; public function Bubbles() { init(); } private function init():void { balls = new Array(); ***centerBall = new Ball(100, 0xcccccc);*** addChild(centerBall); centerBall.x = stage.stageWidth / 2; centerBall.y = stage.stageHeight / 2; for(var i:uint = 0; i < numBalls; i++) { ***var ball:Ball = new Ball(Math.random() * 40 + 5, Math.random() * 0xffffff);*** ball.x = Math.random() * stage.stageWidth; ball.y = Math.random() * stage.stageHeight; ball.vx = Math.random() * 6 - 3; ball.vy = Math.random() * 6 - 3; addChild(ball); balls.push(ball); } addEventListener(Event.ENTER_FRAME, onEnterFrame); } private function onEnterFrame(event:Event):void { for(var i:uint = 0; i < numBalls; i++) { var ball:Ball = balls[i]; move(ball); var dx:Number = ball.x - centerBall.x; var dy:Number = ball.y - centerBall.y; var dist:Number = Math.sqrt(dx * dx + dy * dy); var minDist:Number = ball.radius + centerBall.radius; if(dist < minDist) { var angle:Number = Math.atan2(dy, dx); var tx:Number = centerBall.x + Math.cos(angle) * minDist; var ty:Number = centerBall.y + Math.sin(angle) * minDist; ball.vx += (tx - ball.x) * spring; ball.vy += (ty - ball.y) * spring; } } } private function move(ball:Ball):void { ball.x += ball.vx; ball.y += ball.vy; if(ball.x + ball.radius > stage.stageWidth) { ball.x = stage.stageWidth - ball.radius; ball.vx *= bounce; } else if(ball.x - ball.radius < 0) { ball.x = ball.radius; ball.vx *= bounce; } if(ball.y + ball.radius > stage.stageHeight) { ball.y = stage.stageHeight - ball.radius; ball.vy *= bounce; } else if(ball.y - ball.radius < 0) { ball.y = ball.radius; ball.vy *= bounce; } } } } I think this is due to the non-existance of a Ball.as, when reading the tutorial I assumed it meant that I had to create a movie clip of a ball on stage and then export it for actionscript with the class name being Ball, however when flicking back through the book I saw that a Ball.as already existed, stating that I may need to use this again later on in the book, this read: package { import flash.display.Sprite; public class Ball extends Sprite { private var radius:Number; private var color:uint; public var vx:Number=0; public var vy:Number=0; public function Ball(radius:Number=40, color:uint=0xff0000) { this.radius=radius; this.color=color; init(); } public function init():void { graphics.beginFill(color); graphics.drawCircle(0, 0, radius); graphics.endFill(); } } } This managed to stop all the errors appearing however, it did not transmit any of the effects from Bubbles.as it just braught a Red Ball on the center of the stage. How would I alter this code in order to work in favour of Bubbles.as? Please Help! Thanks!

  • Read Text From Windows Form

    - by omghai2u
    I would like, if for no other reason that an academic exercise, to be able to read text written to a form on a Windows Application. The program appears to be written in non-.NET, but in .NET terms, I think you would describe the program as having a Form with a Label and I would like to read the text from that label. I believe I can see that text being written to the screen with the User32!TextOut (and in other areas User32!DrawString) function. However, it would be nice if I didn't have to hook that function to get the information I'm looking for, but instead if I could just read it from the form directly. So, given a handle to a Window, is it possible to read the text that has been written to that window with functions like TextOut and DrawString using some similar API or other clever means? Or am I going about this the wrong way? Should I just hook the function and look for the text in every call and pray? Thanks!

  • get url:xml why external url does not work

    I am trying to grab information from an external xml with the following code. It only worked when I uploaded same file to my servers. Why cant I grab information from an external url? <script language="javascript"> // This script uses jQuery to retrieve the news XML file and display the contents $(document).ready(function(){ $.ajax({ type: "GET", url: "www.simplyprofound.com/samples/xml_jquery/sample.xml", dataType: "xml", success: function(xml) { $(xml).find('item').each(function(){ var title = $(this).find('title').text(); var source = $(this).find('source').text(); var description = $(this).find('description').text(); $('<div class="news_title"></div>').html(title).appendTo('#news_wrap'); $('<div class="news_source"></div>').html(source).appendTo('#news_wrap'); $('<div class="news_description"></div>').html(description).appendTo('#news_wrap'); }); } }); }); </script>

  • JavaScript Namespace Declaration

    - by Hery
    I created a javascript class as follow: var MyClass = (function() { function myprivate(param) { console.log(param); } return { MyPublic : function(param) { myprivate(param); } }; })(); MyClass.MyPublic("hello"); The code above is working, but my question is, how if I want to introduce namespace to that class. Basically I want to be able to call the class like this: Namespace.MyClass.MyPublic("Hello World"); If I added Namespace.MyClass, it'll throw error "Syntax Error". I did try to add "window.Namespace = {}" and it doesn't work either. Thanks.. :)

  • Is it possible to reference object within the same object?

    - by fudgey
    I've been messing around with jQuery plugin code and I'm trying to put all of my common variables into a single object for easy access. I have included a few examples below on how I've done this, but I'm wondering how others deal with this problem. Lets say I have this var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : $('ul#list').children().length } $.extend(options, defaults); // do other stuff } What I'm trying to do is use the ulist object in as a base, then find the number of li's I guess I could do this: var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : 0 } defaults.listLen = defaults.ulist.children().length; $.extend(options, defaults); // do other stuff } or this: var x = function(options){ var defaults = { ulist : $('ul#list') }; var defaults2 = { listLen : defaults.ulist.children().length } $.extend(defaults, defaults2); $.extend(options, defaults); // do other stuff } The above code samples are just thrown together, and only meant to get the idea across to you. Anyway, is there a better way to do this?

  • Clever "add tag" javascript help needed

    - by Camran
    I have this function for adding options to a Select list: function addOption(selectbox, value, text, cl ) { var optn = document.createElement("OPTION"); optn.text = text; optn.value = value; if (cl==1){ optn.className = "nav_option_main"; } selectbox.options.add(optn); } I have just discovered the "optgroup" tag, but I don't know how to implement it to the drop list. The function above is called on another selectboxes "OnChange" event, to fill sub-select-box with the desired options. I don't think it should be too difficult to add the "optgroup" tag into this, or is it? Thanks and if you need more input let me know...

  • Lazy evaluation with ostream C++ operators

    - by SavinG
    I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

  • Kernel thread exit in linux

    - by Raffo
    Hi guys, I'm here to ask you the difference between a process and a thread in linux. I know that a thread for linux is just a "task", which shares with the father process things that they need to have in common (the address space and other important informations). I also know that the two are creating calling the same function ('clone()'), but there's still something that I'm missing: what really happens when a thread exit? What function is called inside the linux kernel? I know that when a process exits calls the do_exit function, but here or somewhere else there should be a way to understand if it is just a thread exiting or a whole process. Can you explain me this thing or redirect to some textbook?? I tried 'Understanding the linux kernel' but I was not satisfied with it. I'm asking this thing because a need to add things to the task_struct struct, but I need to discriminate how to manage those informations for a process and its children. Thank you.

  • Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?

    - by Rahat
    Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

  • Java, how to trace functions called

    - by user435657
    Hi all, I want to trace the beginning [& ending] of functions called in Java, like the following code: public void foo() { System.out.println("begin of foo()"); ... System.out.println("e-n-d of foo()"); } But maintaining of the dump code System.out.println is something tedious and error-prone, for there may be tens of thounds of function in an class. Any good idea can ease this work? I don't want dump statements all over the file. Implementation of both or one of the beginning & ending traces is perferd. But, if impossible, recordings of that the function has been called is also helpful. I mean not care the exact beginnig and ending, just tell that the function has been called.

  • How can I revert a 'draggable' upon failed AJAX request?

    - by Frank
    I have a draggable div, that needs to be dropped on a droppable. If it is dropped correctly, the droppable calls an AJAX request. If the draggable does not have a valid id or the AJAX request fails, the draggable should be reverted to it's original position. Is that something that can be done with jQuery?! Any help is greatly appreciated!! $("div.draggable").livequery(function(){ $(this).draggable({ revert: 'invalid', distance: 20 }) }); $("#trash").droppable({ tolerance: 'touch', drop: function(event, ui) { var item = ui.draggable; var id = item.attr('id'); if (id) { $.ajax( { type: "POST", url: "delete.php", data: "id=" + id, success: function(html) { if (html) { item.remove(); } else { // FAILED AFTER AJAX // is it possible to revert the draggable from here?? } } }); } else { // FAILED BEFORE AJAX // is it possible to revert the draggable from here?? } } });

  • IE JavaScript Mystery

    - by William Calleja
    I have the following JavaScript function function headerBanner(){ var current = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'none'); if(bannerIndex== $('.bannerImages img').size()){ bannerIndex= 1; }else{ bannerIndex= (bannerIndex*1)+1; } var next = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'block'); } In every browser on the planet, with the exception of IE (8, 7 or less), the above code is working correctly. In Internet Explorer it's going through it and having no effect. I've put alerts at every line of the function and they all fire, even in IE, but the banner simply doesn't change. Is there any reason as to why this is so?

  • Javascript appending onload to a popup window

    - by Hypnotic Meat
    I'm trying to append an onload event to a popup window in the following manner: var explorerWindow = window.open(PARAMS...); explorerWindow.onload = function() {window.opener.unlockObj(id);} The idea is to make the button that generates the popup window readonly, making it usable again once the popup window has loaded all of its contents. However, the event doesn't seem to be firing at all. I even changed it to the following and got nothing: explorerWindow.onload = function() {alert("bloop");} Is there something terribly wrong with my syntax or am I missing something else entirely? Also, I'm using JQuery if there are any appropriate gems there that will help in this situation. I tried the following with similar results, but I'm not so sure I got the call right: $(explorerWindow).load(function() {alert("bloop");}); Any help is greatly appreciated.

  • How to save event handlers, when we set new html for element?

    I have simple html markup: <div id="cont">Some text here <div class="wrap" style="border: 1px solid black;display: inline;"> block element here </div> and another text</div> And jQuery code: $(function(){ $(".wrap").click(function(){ $("#cont").html($("#cont").html().replace(/text/g, "letter")); alert("Click!"); }); $("#d1").click(function(){ alert("#d1 clicked!"); }); }); I expect that click event will be fire any time you clicked by the #d1 div, but when we clicked by .wrap it neve fire again. I understand why it has such behavior, but how to solve it? In my code I can't set click event for #d1 after $("#cont").html($("#cont").html().replace(/text/g, "letter")) because I don't now at execution time if event was set. You can try example on JSBin
