How to get notified about changes of the history via history.pushState?

- by Felix Kling

So now that HTML5 introduces history.pushState to change the browsers history, websites start using this in combination with Ajax instead of changing the fragment identifier of the URL. Sadly that means that those calls cannot be detect anymore by onhashchange. My question is: Is there a reliable way (hack? ;)) to detect when a website uses history.pushState? The specification does not state anything about events that are raised (at least I couldn't find anything). I tried to create a facade and replaced window.history with my own JavaScript object, but it didn't have any effect at all. Further explanation: I'm developing a Firefox add-on that needs to detect these changes and act accordingly. I know there was a similar question a few days ago that asked whether listening to some DOM events would be efficient but I would rather not rely on that because these events can be generated for a lot of different reasons. Update: Here is a jsfiddle (use Firefox 4 or Chrome 8) that shows that onpopstate is not triggered when pushState is called (or am I doing something wrong? Feel free to improve it!). Update 2: Another (side) problem is that window.location is not updated when using pushState (but I read about this already here on SO I think).

IE8 ignores jQuery UI 'dialog' minHeight and height settings

- by Kev

I'm using jQuery 1.4.4 with jQueryUI 1.8.7 to display a modal dialog box. I'm having a problem where IE8 renders a scrollbar and appears to ignore the minHeight and height options in all the many different combinations I've tried them in. In Chrome 8 and Firefox 3.6 my dialogue looks like: In IE 8 it looks like: The markup and script looks like: <a id="create" href="#">Create New Thing</a> <div id="dlg-create-thing" title="Create new thing?"> <form name="create-thing-form" id="dlg-create-thing-form"> <p style="text-align:left"> <span>Name: <input id="thingName" name="thingName" maxlength="12" size="30" /></span> <br /><br /> <b>Thing options:</b><br /><br /> <input type="radio" id="option1" name="theoptions" value="0" checked="checked" />Use this option<br /> <input type="radio" id="option1AndMem" name="theoptions" value="1" />Use this other option </p> </form> </div> <script type="text/javascript"> $(function () { $("#dlg-create-thing").dialog({ autoOpen: false, resizable: false, width: 500, modal: true, minHeight: 280, buttons: { "Create": function () { /* do stuff */ }, "Cancel": function () { /* do other stuff */} } }); $("body").delegate("a[id='create']", "click", function () { $("#dlg-create-thing").dialog('open'); return false; } ); }); </script> How can I fix this (preferably in a nice browser agnostic way, but I'd settle for anything)?

Dynamically change embedded video src in IE/Chrome (works in Firefox)

- by macca1

I'm trying to dynamically change an embedded video on a page. It's working in Firefox but for some reason it's not working in IE and Chrome (strange combination). Here's the HTML: <object id="viewer" width="575" height="344"> <param name="wmode" value="transparent" /> <param name="movie" value="http://www.youtube.com/v/Lmn94kn08Lw&hl=en&fs=1&color1=0x006699&color2=0x54abd6&rel=0" /> <param name="allowFullScreen" value="true" /> <embed id="embeddedPlayer" src="http://www.youtube.com/v/Lmn94kn08Lw&hl=en&fs=1&color1=0x006699&color2=0x54abd6&rel=0" type="application/x-shockwave-flash" allowfullscreen="true" width="575" height="344" wmode="transparent"></embed> </object> And here's my javascript code. A link is clicked to change the video: $("#video a").click( function() { var videoAddress = $(this).attr("href"); $("#embeddedPlayer").attr("src", videoAddress); return false; // stop the default link so it just reloads in the video player } ); Like I said the videos are changing perfectly in Firefox but in IE and Chrome nothing happens. Any ideas?

How does this Bookmarklet allow you to stay signed into this site?

- by Abs

Hello all, I have come across Evernote's bookmarklet and was wondering how this worked. You can just drag it to your bookmark and go to any webpage, click that bookmarklet and it will first ask you to login in. All this I have done already and know how it works. The bit that I don't understand is that when you log in they authenticate you and allow you to submit stuff (in this case, a site url etc). When you are done the bookmarklet which placed a small overlay on the page you are viewing disappears. When you go to a new tab and use the bookmarklet again you are still logged in! How? I can see they are using an iFrame when their bookmarklet loads the overlay onto the page - but do they set cookies or something? If so, is this secure? Anyone can change the values? Or are they using some sort of private/public key system Btw, I would like to replicate this Bookmarklet using PHP/Javascript(JQuery maybe). I would appreciate if anyone can help me understand how they do this or point me to relevant tutorials. Thanks all for any help.

Using innerHTML to add ordered list fails in IE

- by Matt

I'm using the following Javascript code to populate a DIV with an ordered list: // send script back in split list var scriptList = script.split("\n"); var finalScript = "<ol>\n"; var count = 0; while(scriptList.length >= count) { if((scriptList[count]=="") || (scriptList[count] == undefined)) { count ++; continue; } finalScript = finalScript + "<li>" + scriptList[count] + "</li>\n"; count ++; } finalScript = finalScript + "</ol>"; scriptingDiv.innerHTML = finalScript; In firefox, if i look in the DOM using Firebug, this correctly translates to the following and correctly displays an ordered list. <ol> <li>This is the first item in the list</li> <li>This is the second item in the list</li> </ol> In IE, it displays as if the </li> tags are <br /> tags and ignores all the other tags, like this: This is the first item in the list This is the second item in the list Do I need to dynamically add the ordered list to the DOM for this to work? As opposed to just setting the html code in the div using .innerHTML? TIA

JQuery quiz app - use <id> tag to toggle variable on/off

- by hairyllama

Hi, I am writing a jquery phonegap quiz app and have a number of categories from which a user can select via checkbox. Relevant questions belonging to those categories are then returned. However, I have two huge switch statements to change the relevant variables from 0 to 1 if the checkbox for that category is selected and vice versa (this info is used to build a compound db query). The value of the variable behind the checkbox is only ever 0 or 1, so is there a better way to do this? My HTML is: <h2>Categories</h2> <ul class="rounded"> <li>Cardiology<span class="toggle"><input type="checkbox" id="cardiology" /></span></li> <li>Respiratory<span class="toggle"><input type="checkbox" id="respiratory" /></span></li> <li>Gastrointestinal<span class="toggle"><input type="checkbox" id="gastrointestinal" /></span></li> <li>Neurology<span class="toggle"><input type="checkbox" id="neurology" /></span></li> </ul> My Javascript is along the lines of: var toggle_cardiology = 0; var toggle_respiratory = 0; var toggle_gastrointestinal = 0; var toggle_neurology = 0; $(function() { $('input[type="checkbox"]').bind('click',function() { if($(this).is(':checked')) { switch (this.id) { case "cardiology": toggle_cardiology = 1; break; case "respiratory": toggle_respiratory = 1; break; case "gastrointestinal": toggle_gastrointestinal = 1; break; case "neurology": toggle_neurology = 1; break; etc. (which is cumbersome with 10+ categories plus an else statement with a switch to change them back) I'm thinking of something along the lines of concatenating the HTML id tag onto the "toggle_" prefix - in pseudocode: if (toggle_ + this.id == 1){ toggle_ + this.id == 0} if (toggle_ + this.id == 0){ toggle_ + this.id == 1} Thanks, Nick.

How can I set/store cookie when anchor clicked

- by Unaverage Guy

I am trying to use Cookie so that a default style OR a specific style is applied in reference to the anchor tag clicked, even when the browser is closed/reopen. So if the user clicked the second link, close or refresh the browser and reopen, than the style should still be active, if it is their first time the default should apply. This is a little over my turf. Here is the HTML: <a id="default" href="#/">Default Style</a> <a id="style2" href="#/">Style 2</a> <a id="style3" href="#/">Style 3</a> <ol> <li><span>Hello World</span></li> </ol> JQuery: (Compliments of StackOverflow) <script type="text/javascript"> $('#default').on('click',function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('default'); }); $('#style2').click(function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('style2'); }); $('#style3').click(function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('style3'); }); </script> CSS: <style type="text/css"> .default{ color: #333; } .style2{ color: #999; } .style3{ color: #800; } </style>

Iterate Through JSON Data for Specific Element - Similar to XPath

- by Highroller

I am working on an embedded system and my theory of the overall process follows this methodology: 1. Send a command to the back end asking for account information in JSON format. 2. The back end writes a JSON file with all accounts and associated information (there could be 0 to 16 accounts). 3. Here's where I get stuck - use JavaScript (we are using the JQuery library) to iterate through the returned information for a specific element (similar to XPath) and build an array based on the number of elements found to populate a drop-down box to select the account you want to view and then do stuff with the account info. So my code looks like this: loadAccounts = function() { $.getJSON('/info?q=voip.accounts[]', function(result) { var sipAcnts = $("#sipacnts"); $(sipAcnts).empty(); // empty the dropdown (if necessarry) // Get the 'label' element and stick it in an array // build the array and append it to the sipAcnts dropdown // use array index to ref the accounts info and do stuff with it } So what I need is the JSON version of XPath to build the array of voip.accounts.label. The first account info looks something like this: { "result_set": { "voip.accounts[0]": { "label": "Dispatch1", "enabled": true, "user": "1234", "name": "Jane Doe", "type": "sip", "sip": { "lots and lots of stuff": }, } } } Am I over complicating the issue? Any wisdom anyone could thrown down would be greatly appreciated.

Run script after Jquery finish

- by Felipe Fernández

First let's explain the hack that I was trying to implement. When using Total Validator Tool through my web page and I get following error: [WCAG v1 6.3 (A), US-508-l] Consider providing a alternative after each tag As my page relies heavily on javascript I can't provide a real alternative, so I decided to add an empty noscript tag after every script appearence. Let's say I need to provide a clean report about accesibility about my web page even the hack is senseless. (I know the hack is unethical and silly, let's use it as example material, but the point of my post are the final questions) I tried the following approach: $(document).ready(function(){ $("script").each(function() { $(this).after("<noscript></noscript>"); }); }); The problem raises because I have a jQueryUI DatePicker component on my page. jQuery adds a script section after the DOM is ready so my hack fails as miss this section. So the questions are: How handles jQuery library to be executed after document is ready? How can I run my code after jQuery finish its labours?

Updating table row by given id with jQuery

- by fabrik

Hello all! I need to update a specific table row (via tr id="unique_key") after a successful AJAX call. HTML fragment: <a name=\"p{$product_id}\" class=\"tr{$product_id}\"></a> <tr id="p{product_id}" class="item-row"> <td><h3>{product_id}</h3><a rel="facebox" href="ajax_url">{product_name}</a></td> <td>{image_information}</td> <td>{image_sortiment}</td> <td>{product_status}</td> </tr> Javascript: // AJAX Call success: function(msg){ $('#p' + prod_id).remove(); $('.tr' + prod_id).after(msg); $('#p' + prod_id + ' a[rel*=facebox]').facebox(); } ... What happens: The table row removed Anchors grouped into one single row (not before their <tr>'s) so my 'hook' disappears AJAX result inserted over the whole table (after my 'hook' but still a wrong place) What's wrong with my idea? How can i force jQuery to 'overwrite' the required table row?

Reading HTML header info of files via JS

- by Morten Repsdorph Husfeldt

I have a product list that is generated in ASP. I have product descriptions for each product in an HTML file. Each HTML file is named: <product.id>.html. Each HTML file size is only 1-3 kb. Within the HTML file is <title> and <meta name="description" content="..." />. I want to access these in an efficient way so that I can output this as e.g.: document.write(<product.id>.html.title);<br/> document.write(<product.id>.html.description); I have a working solution for the individual products, where I use the description file - but I hope to find a more efficient / simple approach. Preferably, I want to avoid having 30+ hidden iframes - Google might think that I am trying to tamper with search result and blacklist my page. Current code: <script type="text/javascript"> document.getElementById('produkt').onload = function(){ var d = window.frames[frame].document; document.getElementById('pfoto').title = d.title : ' '; document.getElementById('pfoto').alt = d.getElementsByName('description')[0].getAttribute('content', 0) : ' '; var keywords = d.getElementsByName('keywords')[0].getAttribute('content', 0) : ' '; }; </script>

Send email from webpage without postback/refresh

- by jb

Hi all. Long time reader, first time writer. Quick query i hope someone can help me with. I have a webpage (php, javascript) which has a small contact form for a user to fill in and email us. Not a problem in itself, i have a working form already. Nothing noteworthy, just a form posting to a php page which sends an email. <form id="myform" name="myform" method="post" action="Mailer.php"> So user fills in form, hits submit and the page changes to mailer.php and they find their way back to where they were. What I want instead is for the to stay on the same page when submit is pushed. The form div to update itself to just say 'message sent' or something. I just want to avoid a full page refresh. Much like how on say facebook, commenting on a status only updates that div. Hope that is phrased clearly enough. Cheers all,

Overlaying one div over another, but not knowing the size of the div

- by andyuk

I'm trying to lay one div over another. This is really simple if you know the dimensions of the div. Solved here: How to overlay one div over another div So, here is my HTML: <div class="container"> <div class="overlay"></div> <div class="content"></div> </div> In my case, I don't know the exact dimensions of the "content" or "container" div. This is because I don't have control over any of the content in the div (we are making our app extensible for 3rd party developers). See my example on jsFiddle The overlay should cover the content entirely. Width 100% and Height 100%. However, this does not work because in my example I positioned the overlay absolutely. One solution is to use JavaScript to get the size of the content div and then set the size of the overlay. I don't like this solution much since if image sizes are not specified, you need to wait until images are loaded and recalculate the size of the div. Is there any way of solving this problem in CSS?

Determine mouse click for all screen resolutions

- by Hallik

I have some simple javascript that determines where a click happens within a browser here: var clickDoc = (document.documentElement != undefined && document.documentElement.clientHeight != 0) ? document.documentElement : document.body; var x = evt.clientX; var y = evt.clientY; var w = clickDoc.clientWidth != undefined ? clickDoc.clientWidth : window.innerWidth; var h = clickDoc.clientHeight != undefined ? clickDoc.clientHeight : window.innerHeight; var scrollx = window.pageXOffset == undefined ? clickDoc.scrollLeft : window.pageXOffset; var scrolly = window.pageYOffset == undefined ? clickDoc.scrollTop : window.pageYOffset; params = '&x=' + (x + scrollx) + '&y=' + (y + scrolly) + '&w=' + w + '&random=' + Date(); All of this data gets stored in a DB. Later I retrieve it and display where all the clicks happened on that page. This works fine if I do all my clicks in one resolution, and then display it back in the same resolution, but this not the case. there can be large amounts of resolutions used. In my test case I was clicking on the screen with a screen resolution of 1260x1080. I retrieved all the data and displayed it in the same resolution. But when I use a different monitor (tried 1024x768 and 1920x1080. The marks shift to the incorrect spot. My question is, if I am storing the width and height of the client, and the x/y position of the click. If 3 different users all with different screen resolutions click on the same word, and a 4th user goes to view where all of those clicks happened, how can I plot the x/y position correctly to show that everyone clicked in the same space, no matter the resolution? If this belongs in a better section, please let me know as well.

AngularJS: Using Shared Service(with $resource) to share data between controllers, but how to define callback functions?

- by shaunlim

Note: I also posted this question on the AngularJS mailing list here: https://groups.google.com/forum/#!topic/angular/UC8_pZsdn2U Hi All, I'm building my first AngularJS app and am not very familiar with Javascript to begin with so any guidance will be much appreciated :) My App has two controllers, ClientController and CountryController. In CountryController, I'm retrieving a list of countries from a CountryService that uses the $resource object. This works fine, but I want to be able to share the list of countries with the ClientController. After some research, I read that I should use the CountryService to store the data and inject that service into both controllers. This was the code I had before: CountryService: services.factory('CountryService', function($resource) { return $resource('http://localhost:port/restwrapper/client.json', {port: ':8080'}); }); CountryController: //Get list of countries //inherently async query using deferred promise $scope.countries = CountryService.query(function(result){ //preselected first entry as default $scope.selected.country = $scope.countries[0]; }); And after my changes, they look like this: CountryService: services.factory('CountryService', function($resource) { var countryService = {}; var data; var resource = $resource('http://localhost:port/restwrapper/country.json', {port: ':8080'}); var countries = function() { data = resource.query(); return data; } return { getCountries: function() { if(data) { console.log("returning cached data"); return data; } else { console.log("getting countries from server"); return countries(); } } }; }); CountryController: $scope.countries = CountryService.getCountries(function(result){ console.log("i need a callback function here..."); }); The problem is that I used to be able to use the callback function in $resource.query() to preselect a default selection, but now that I've moved the query() call to within my CountryService, I seemed to have lost what. What's the best way to go about solving this problem? Thanks for your help, Shaun

IE and replaceWith not preserving radio button state

Trouble using 'eval' to define a toplevel function when called from within an object.

- by mschaef

I've written (in JavaScript) an interactive read-eval-print-loop that is encapsulated within an object. However, I recently noticed that toplevel function definitions specified to the interpreter do not appear to be 'remembered' by the interpreter. After some diagnostic work, I've reduced the core problem to this: var evaler = { eval: function (str) { return eval(str); }, }; eval("function t1() { return 1; }"); // GOOD evaler.eval("function t2() { return 2; }"); // FAIL After running this script, I have a definition for t1, and no defintion for t2. The act of calling eval from within evaler is sufficiently different from the toplevel call that the global definition does not get recorded. What does happen is that the call to evaler.eval returns a function object, so I'm presuming that t2 is being defined and stored in some other set of bindings that I don't have access to. (It's not defined as a member in evaler.) Is there any easy fix for this? I've tried all sorts of fixes, and haven't stumbled upon one that works. (Most of what I've done has centered around putting the call to eval in an anonymous function, and altering the way that's called, chainging __parent__, etc.) Any thoughts on how to fix this?

What techniques do you use for emitting data from the server that will solely be used in client side scripts?

- by chuck

Hi all, I never found an optimal solution for this problem so I am hoping that some of you out there have a few solutions. Let's say I need to render out a list of checkboxes and each checkbox has a set of additional data that goes with it. This data will be used purely in the context of javascript and jquery. My usual strategy is to render this data in hidden fields that are grouped in the same container as the checkbox. My rendered HTML will look something like this: <div> <input type="checkbox" /> <input type="hidden" class="genreId" /> <input type="hidden" class="titleId" /> </div> My only problem with this is that the data in the hidden fields get posted to the server when the form is submitted. For small amounts of data, this is fine. However, I frequently work with large datasets and a large amount of data is needlessly transferred. UPDATE: Before submitting this post, I just saw that I can add a "DISABLED" attribute to my input element to suppress the submission of data. Is this pretty much the best approach that I can take? Thanks

Why changing the images name on server results in calling the old ones?

- by moderns

I am running a slideshow on Ubuntu 12.04.1 that loads the images (slide1.jpg, slide2.jpg, slide3.jpg.., slide5.jpg) using the Javascript and styles as below: document.getElementById('slide_area').className='slide'+step; .slide1{background-image: url(../upload/slide1.jpg)} .slide2{background-image: url(../upload/slide2.jpg)} .slide3{background-image: url(../upload/slide3.jpg)} .slide4{background-image: url(../upload/slide4.jpg)} .slide5{background-image: url(../upload/slide5.jpg)} When I change the images names (show1.jpg, show2.jpg, show3.jpg.., show5.jpg) and also change the style as below: .slide1{background-image: url(../upload/show1.jpg)} .slide2{background-image: url(../upload/show2.jpg)} .slide3{background-image: url(../upload/show3.jpg)} .slide4{background-image: url(../upload/show4.jpg)} .slide5{background-image: url(../upload/show5.jpg)} And open the network section on Chrome, I see the server is calling the new name and old name for images! I added the header in the index.php: header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); Nothing worked out with me and the slideshow doesn't work properly when I change the name of images even when clearing the browser cache as I load images sequentially (one by one) depending on imageObject.complete property! But without changing the name everything is going perfect and the images are loaded smoothly! Thank you for your help!

How can I serialize functions using JSON or some other serialization library?

- by Oragamster

I am trying to create a program that uses javascript to write a simple textadventure that I can then post on my blog and run on my iphone. I have run into a problem though. I was trying to make it so that my program would save it's state into cookies using JSON to convert it into strings and then post it into a cookie but then I realised that I couldn't serialize the functions that are on my item object. I was trying to make it so that my item would have an associative array that would contain the name of the use as the key and the function as the value. This worked well untill I tried to serialize it. I learned that I could create a JSON like serialization for functions by storing the body into a string and using escape charectors for the double quotes but for some reason I was unable to make my cookie with the function as the string stored. When I posted the cookie and then tried to get it back the string wasn't there. My code and the over all project are on my site if you want to look at that, though my full code including the item actions are not posted yet.

How to search within an xml data set?

For example, if I search "some" for the following data it returns me the <id> and <title>. <resource> <id>101</id> <title>Test Environment</title> <description><b>Some</b> description. </description> <type>classroom</type> </resource> <resource> <id>102</id> <title>ABC Test Environment</title> <description><b>Some</b> another description. </description> <type>classroom</type> </resource> ... I had a look on on xpath e.g. $xml->xpath('//title') but looks for elements only. Basically what I need to do is to create a functionality where users can keyword search within the above data set which I receive from third party api in the above format. Any ideas how I can achieve this? using PHP/ Javascript etc. Thanks.

Target a link if that link links to the current page?

- by Des

this may be a stupid question as I can't seem to find an answer :P Is there a way with javascript/jQuery to Target all links on a page ONLY if they link to the current page? Say i've got a static sidebar on ALL pages, for intents and purposes: <ul id="sidebar"> <li><a href="/one">One</a></li> <li><a href="/two">Two</a></li> <li><a href="/three">Three</a></li> </ul> Notice the code for ALL of them is the same. Let's say I'm on "www.domain.com/two" - Is there a way to target <li><a href="#">Two</a></li> because it's linking to the current page? ***ANSWERED***** The guy deleted his answer - but I used it to create this - var linksToCurrentPage = $('a[href="' + window.location.href + '"]'); if (linksToCurrentPage) { $('a').addClass('currently-active'); }; which worked :)
