• How to proprely remove a flash object from a HTML page.

  - by Niklaos

  Hi guys. I made a website using AJAX (with jquery) for the navigation. The pages of the site are sliding and I use remove() to destroy the old page. Every thing seems alright, but some times the browser crashes when he tries to remove the old page containing a Flash object. I suppose this is because Flash is still executing the Flash object. My question is simple. How do i remove this Flash's object for my page without having the browser crashing on my face ? Is there a way to stop the Flash execution before removing the object ? Thanks for your help.

• How to replace href using javascript regex in Firefox?

  - by Andrei

  I try to change some links on a webpage using the following code for jQuery on Rails $(function () { $('#lesson a').live('click', function () { $.getScript(this.href.replace(/^(http...[^\/]+)?\/+(.*)$/,'/ajax/\\$2')); return false; }); }) This trick works for Chrome and Safari, but fails (nothing happens on click) for Firefox and Opera. What can be wrong with the code? EDIT1: The webpage contains: <div id="lesson"> <a href="/subj1">Subject 1</a> ... </div> On click, a browser (i.e. Firefox and Opera) should make an ajax-request of /ajax/subj1.

• Need to dynamically-generate a "sticky note" text

  - by gravyface

  Working on a website that has an image of a sticky note which will change text somewhat frequently (every month or so) as new "todo" items are created on it. Font I'm currently using is not Web Safe and the text is slightly angled to match the skew of the sticky note as well. Now I'm a pragmatist, and in situations like this I would normally secede defeat and opt for something more CSS/HTML practical. But no more! I'm falling a bit behind on what's going on with HTML5, CSS3, PNG graphics, Flash (ugh), and/or any other rich visuals. I'm decent with PHP/CSS/JS (jquery), have dabbled in Flash/actionscript too. My question is: what tools/method should I be looking at here?

• Which Lightbox implementation allows to display larger preview immediately on mouse enter?

  - by Marek

  There are quite a few Lightbox implementations. Is there any such that it displays a larger version of the image as soon as the user enters the thumbnail with the mouse? The preview should be displayed next to mouse position. The shaded lightbox effect is not required.

• Changing Dropdown based on Other Dropdown Menu

  - by Shaded

  I've seen a few questions like this, but mine is a bit more specific so I hope this isn't considered a repost. I am working on a website that is built with struts 2 and hibernate. I need to dynamically populate a drop down menu using data from a sql query based on an option selected in another drop down menu. So basically when the first option is selected I need to rehit the server and get the results from a query like SELECT column FROM table WHERE option = dropDownOption On top of that, I would really like to use ajax to only refresh the affected elements, however I'm really unfamiliar with ajax. I have jquery on this project and I found they have some ajax built in, but is this a good method for using it? any advice on this topic would be appreciated.

• How can you pass GET values to another url in php? GET value forwarding

  - by gobackpacking

  Ok, so I'm using Jquery's AJAX function and it's having trouble passing a URL with a http address. So I'm hoping to "get" the GET values and send them to another URL — so: a local php file begin passed GET values, which in turn forwards the GET values to another url. Maybe curl is the answer? I don't know. It's got to be a very short answer I know. pseudo code: //retrieve the GET values $var retrieve [GET] //passing it to another url send get values to url ($var, url_address)

• How can I implement drag-out-to-delete in Flex?

  - by Chris R

  I have a List component from which I'd like to be able to remove items using drag & drop, but without having a specific target. If you use the mac, the behaviour I'm looking for is something like what the Dock uses; when you drag something out of the bounds of the control it should get an icon that indicates that it'll be deleted (OSX uses a cloud or something?) and then if you release it it will be removed from the list. How can I do this? (If I need to provide a more clear description, please comment; I'll fill in what I can)

• How do I add a loading indicator to my page while my iframe loads?

  - by keybored

  I am currently creating a page where upon clicking a link an iframe is inserted into a div and it's contents loaded. I do this using the following jQuery call: $('#mydiv').html('<iframe src="sourcelink.html" frameborder="0" width="760" height="2400" scrolling="no"></iframe>'); Sometimes the source content loads very slowly and, as a result, it looks like nothing is happening. I would like to have a simple loading animation while the content is loading while the iframe's content loads. When the iframe finishes loading it's content should pop in and the loading animation should go away. I've been considering a couple ways I could do this (e.g. having a separate loader div to simply swap the two in and out) but I'm not sure of what the 'best' approach to solving this problem is. Perhaps I shouldn't be using .html()? I'm open to suggestion if there is a more correct solution.

• What is the difference between an object's scope and it's context in javascript?

  - by DKinzer

  In the vernacular, scope and context have a lot in common. Which is why I get confused when I read references to both, such as in the quote below from an article on closures: Scope refers to where variables and functions are accessible, and in what context it is being executed. (@robertnyman) As far as I can tell, context is just a reference to an object. Can someone please explain what exactly is context, as used, for instance, in the jQuery syntax, $(selector, context). And is an object's scope the same at it's context?

• detecting returned errors with $.post

  - by sova

  I'm using $.post to send a query to a JSP which returns some awesome data for me. If the query is malformed, however, the page returns with "error on page" and an HTTP Status of 500 Internal Server Error in jQuery, how can I detect this error so I can tell the user of the failure? runQuery : function () { $.post( admin_stats.runQueryURL, { buster : Math.random, statsQuery: admin_stats.getQuery(), jsp: 'admin_statsQuery' }, admin_stats.handleStatsQuery, "html" ); the returned data is an HTML table which is sufficient for this project at the moment. Also: totally open to criticism if this is ugly or not the way I should be doing things =)

• Transparent Select/Option text in IE

  - by Valchris

  I've created the JS fiddle to demonstrate my problem: http://jsfiddle.net/C8NUf/1/ HTML: <select> <option> Test </option> <option> Another Test </option> </select> Style: select { color: transparent; } In chrome, the selected text "test" is properly blanked out by setting the color to transparent, in IE the test is still black. How can I fix this issue in IE? Ideally I want to make this change via JQuery, but that doesn't seem very relevant to the overall problem. Thanks, Daniel

• Firing a Keyboard Event at the Body - JavaScript (?)

  - by user317985

  I've done a lot of research on this but have come up empty handed. What I would like to do is invoke or create an event for the right arrow key (Key Code 39). I was planning on using an onclick event inside an tag to go to a function where this event could be 'fired'. Any help would be appreciated. If anyone needs context, I have a jQuery content slider that's functionality is very hard to alter and currently the functionality I need to emulate only occurs when a user hits the right arrow on their keyboard. What I would like to do is tie an onclick() event to a image that when clicked on fires the right keyboard event and the content will slide. Please let me know if I can provide further details or explanation. My working demo for this is: http://greenplanet3d.com

• iframe problem using javascript

  - by Arjun Singh

  Does anyone know how to get the HTML out of an IFRAME? I have tried several different ways: document.getElementById('iframe01').contentDocument.body.innerHTML, document.frames['iframe01'].document.body.innerHTML, document.getElementById('iframe01').contentWindow.document.body.innerHTML, etc but none of them worked. I believe the reason they're not working is that the content of my iframe doesn't have a body tag (I'm loading XML). Any other way to get all the contents of the iframe? I am open to jQuery too. This: document.getElementById('iframe01').contentWindow.document.body.innerHTML works fine in the IE, but this: document.getElementById('iframe01').contentDocument.body.innerHTML does not work for FF.

• Adding fields until screen is full

  - by Eric

  For the sake of this question, let us suppose that I want a row of buttons. I want to put as many buttons in that row as I can fit on the screen, but no more. In other words, as long as a prospective button will not be cut off or have its text shortened, add it. It seems that I should be able to do something like: HorizontalFieldManager hfm = new HorizontalFieldManager(); int remainingWidth = Display.getWidth(); int i =0; while(true) { ButtonField bf = new ButtonField("B " + i); remainingWidth -= bf.getWidth(); if(remainingWidth<0) break; hfm.add(bf); i++; } add(hfm); But this doesn't work. bf.getWidth() is always 0. I suspect that this is because the button has not yet been laid out when I query for the width. So, perhaps I could just make sure the buttons are always the same size. But this won't work for a few reasons: Different BB platforms have different looks for buttons and text that will fit on a button on a Curve won't fit on a button on a Storm. 3rd party themes may change the look of buttons, so I can't even count on buttons being a certain size on a certain platform. Is there no way for me to actually check the remaining space before adding a button? It feels like a fairly useful feature; am I just missing something?

• Can't append to second container

  - by George Katsanos

  I have the following script: (function($) { $.fn.easyPaginate = function(options){ var defaults = { step: 4, delay: 100, numeric: true, nextprev: true, controls: 'pagination', current: 'current' }; var options = $.extend(defaults, options); var step = options.step; var lower, upper; var children = $(this).children(); var count = children.length; var obj, next, prev; var page = 1; var timeout; var clicked = false; function show(){ clearTimeout(timeout); lower = ((page-1) * step); upper = lower+step; $(children).each(function(i){ var child = $(this); child.hide(); if(i>=lower && i<upper){ setTimeout(function(){ child.fadeIn('fast') }, ( i-( Math.floor(i/step) * step) )*options.delay ); } if(options.nextprev){ if(upper >= count) { next.addClass('stop'); } else { next.removeClass('stop'); }; if(lower >= 1) { prev.removeClass('stop'); } else { prev.addClass('stop'); }; }; }); $('li','#'+ options.controls).removeClass(options.current); $('li[data-index="'+page+'"]','#'+ options.controls).addClass(options.current); if(options.auto){ if(options.clickstop && clicked){}else{ timeout = setTimeout(auto,options.pause); }; }; }; function auto(){ if(upper <= count){ page++; show(); } else { page--; show(); } }; this.each(function(){ obj = this; if(count>step){ var pages = Math.floor(count/step); if((count/step) > pages) pages++; var ol = $('<ol id="'+ options.controls +'" class="pagin"></ol>').insertAfter(obj); if(options.nextprev){ prev = $('<li class="prev">prev</li>') .appendTo(ol) .bind('click', function() { //check to see if there are any more pages in the negative direction if (page > 1) { clicked = true; page--; show(); } }); } if(options.numeric){ for(var i=1;i<=pages;i++){ $('<li data-index="'+ i +'">'+ i +'</li>') .appendTo(ol) .click(function(){ clicked = true; page = $(this).attr('data-index'); show(); }); }; }; if(options.nextprev){ next = $('<li class="next">next</li>') .appendTo(ol) .bind('click', function() { //check to see if there are any pages in the positive direction if (page < (count / 4)) { clicked = true; page++; show(); } }); } show(); }; }); }; })(jQuery); jQuery(function($){ $('ul.news').easyPaginate({step:4}); }); which is a carousel-like plugin that produces this html structure for the navigation: <ol id="pagination" class="pagin"><li class="prev">prev</li><li data-index="1" class="">1</li><li data-index="2" class="">2</li><li data-index="3" class="current">3</li><li class="next stop">next</li></ol> And all I want is to enclose this list in a div. Seems simple, but appendTo doesn't want to cooperate with me, or I'm doing something wrong (I'd appreciate if you would help me understand what that is..) So I'm modifying as such: var ol = $('<ol id="'+ options.controls +'" class="pagin"></ol>'); var tiv = $('<div id="lala"></div>'); ol.appendTo('#lala'); tiv.insertAfter(obj); I know how to chain, but I'm in "debugging" mode trying to understand why I don't get the result I imagine I would get: <div id="lala> <ol id="pagination><li>...... </li></ol> </div> I tried putting some console.log's to see the status of my variables but couldn't find something useful.. I guess there's something with DOM insertion I don't get.

• Keeping Track of Dependant Third-party Library Releases

  - by Sonny

  I am building a web application that is dependent upon several third-party libraries. What is a good strategy for making sure that you're always using the most fully patched versions? A simple method would be to keep the versions written down and visit the websites at regular intervals, but I am looking for some way to get the information 'pushed' to me if possible. I figured that there might be others out there who have needed to do the same thing and have worked out a good solution. Here are a few libraries I am using: Zend Framework jQuery HTMLPurifier Markdownify InnovaStudio WYSIWYG Editor Fancybox MojoZoom

• Is it so bad to have heaps of elements in your DOM?

  - by alex

  I am making a real estate non interactive display for their shop window. I have kicked jCarousel into doing what I want: Add panels per AJAX Towards the end of the current set, go and AJAX some new panels and insert them This works fine, but it appears calling jQuery's remove() on the prior elements cause an ugly bump. I'm not sure if calling hide() will free up any resources, as the element will still exist (and the element will be off screen anyway). I've seen this, and tried carousel.reset() from within a callback. It just clears out all the elements. This will be running on Google Chrome on Windows XP, and will solely by displaying on LCD televisions. I am wondering, if I can't find a reasonable solution to remove the extra DOM elements, will it bring my application to a crawl, or will Chrome do some clever garbage collecting? Or, how would you solve this problem? Thanks

• Solution for using `this` keyword in ajax calls within methods?

  - by dqhendricks

  I am creating a JavaScript class. Some of the methods contain AJAX calls using JQuery. The problem I am comming accross is that I cannot use the this keyword within the AJAX callbacks due to a change in scope. I have come up with a hackey solution, but I am wondering what is the best practice way around this? Here is an example: var someClass = function() { var someElement = $('form'); this.close = function() { someElement.remove(); }; this.query = function() { $.ajax({ url: someurl, success: function() { this.close(); // does not work because `this` is no longer the parent class } }); }; };

• How to load the content of a page into another window?

  - by Cristian Castiblanco

  I'm building a Dashboard and for some stupid reasons my boss wants to load it in a frame on the homepage (yes a frame, he still lives in the 1990s). Anyway, sometimes the dashboard needs some room so that it can show all charts correctly, so I want to add a feature to load the content of the dashboard into a new window. The problem is that, if the user has had some interaction with the dashboard, it will contain modal dialogs, new images, etc... so I want to load all the dashboard content into a new window without reloading its content. Of course, the user should be able to continue browsing the dashboard without problems. How can I do that? I'm using jQuery as my JavaScript framework.

• Understanding "this" keyword

  - by Raffaele

  In this commit there is a change I cannot explain deferred.done.apply( deferred, arguments ).fail.apply( deferred, arguments ); becomes deferred.done( arguments ).fail( arguments ); AFAIK, when you invoke a function as a member of some object like obj.func(), inside the function this is bound to obj, so there would be no use invoking a function through apply() just to bound this to obj. Instead, according to the comments, this was required because of some preceding $.Callbacks.add implementation. My doubt is not about jQuery, but about the Javascript language itself: when you invoke a function like obj.func(), how can it be that inside func() the this keyword is not bound to obj?

• Wait for function to finish before executing the rest

  - by Wurlitzer

  When the user refreshes the page, defaultView() is called, which loads some UI elements. $.address.change() should execute when defaultView() has finished, but this doesn't happen all the time. $.address.change() cannot be in the success: callback, as it's used by the application to track URL changes. defaultView(); function defaultView() { $('#tout').fadeOut('normal', function() { $.ajax({ url: "functions.php", type: "GET", data: "defaultview=true", async: false, success: function (response) { $('#tout').html(response).fadeIn('normal'); } }); }); } $.address.change(function(hash) { hash = hash.value; getPage(hash); }); I'm at a loss as to how to make $.address.change() wait for defaultView() to finish. Any help would be appreciated.

• Android : Stop image scaling down

  - by John Smith

  Hi, I'm trying to draw an image in a view but having problems trying to maintain the scale of the original image. Basically, I have a small view and I would like to show part of the image in the view. The intention then is to perform a translation on the image so that a different part appears in the view. No matter what I try, either the image is down-scaled automatically to fit the view or the whole image is viewable. I've tried playing about with the settings on BitmapDrawable, ImageView and Layout to no avail. Anyone know a good way to achieve this?
