  • Finding the last focused element

    - by Joshua Cody
    I'm looking to determine which element had the last focus in a series of inputs, that are added dynamically by the user. This code can only get the inputs that are available on page load: $('input.item').focus(function(){ $(this).siblings('ul').slideDown(); }); And this code sees all elements that have ever had focus: $('input.item').live('focus', function(){ $(this).siblings('ul').slideDown(); }); The HTML structure is this: <ul> <li><input class="item" name="goals[]"> <ul> <li>long list here</li> <li>long list here</li> <li>long list here</li> </ul></li> </ul> <a href="#" id="add">Add another</a> On page load, a single input loads. Then with each add another, a new copy of the top unordered list's contents are made and appended, and the new input gets focus. When each gets focus, I'd like to show the list beneath it. But I don't seem to be able to "watch for the most recently focused element, which exists now or in the future." To clarify: I'm not looking for the last occurrence of an element in the DOM tree. I'm looking to find the element that currently has focus, even if said element is not present upon original page load. So in the above image, if I were to focus on the second element, the list of words should appear under the second element. My focus is currently on the last element, so the words are displayed there. Do I have some sort of fundamental assumption wrong?

  • How to detect Links with out anchor element in a plain text

    - by dhee
    If user enters his text in the text box and saves it and again what's to add some more text he can edit that text and save it if required. Firstly if user enters that text with some links I, detected them and converted any hyperlinks to linkify in new tab. Secondly if user wants to add some more text and links he clicks on edit and add them and save it at this time I must ignore the links that already hyperlinked with anchor button Please help and advice For example: what = "<span>In the task system, is there a way to automatically have any site / page URL or image URL be hyperlinked in a new window?</span><br><br><span>So If I type or copy http://www.stackoverflow.com/&nbsp; for example anywhere in the description, in any of the internal messages or messages to clients, it automatically is a hyperlink in a new window.</span><br><a href="http://www.stackoverflow.com/">http://www.stackoverflow.com/</a><br> <br><span>Or if I input an image URL anywhere in support description, internal messages or messages to cleints, it automatically is a hyperlink in a new window:</span><br> <span>https://static.doubleclick.net/viewad/4327673/1-728x90.jpg</span><br><br><a href="https://static.doubleclick.net/viewad/4327673/1-728x90.jpg">https://static.doubleclick.net/viewad/4327673/1-728x90.jpg</a><br><br><br><span>This would save us a lot time in task building, reviewing and creating messages.</span> Test URL's http://www.stackoverflow.com/ http://stackoverflow.com/ https://stackoverflow.com/ www.stackoverflow.com //stackoverflow.com/ <a href='http://stackoverflow.com/'>http://stackoverflow.com/</a>"; I've tried this code function Linkify(what) { str = what; out = ""; url = ""; i = 0; do { url = str.match(/((https?:\/\/)?([a-z\-]+\.)*[\-\w]+(\.[a-z]{2,4})+(\/[\w\_\-\?\=\&\.]*)*(?![a-z]))/i); if(url!=null) { // get href value href = url[0]; if(href.substr(0,7)!="http://") href = "http://"+href; // where the match occured where = str.indexOf(url[0]); // add it to the output out += str.substr(0,where); // link it out += '<a href="'+href+'" target="_blank">'+url[0]+'</a>'; // prepare str for next round str = str.substr((where+url[0].length)); } else { out += str; str = ""; } } while(str.length>0); return out; } Please help Thanks.

  • How to prevent Closure Compiler from renaming "true", "false" and "null"

    - by Armagan Amcalar
    Google Closure Compiler renames all "true", "false" and "null" occurences in code like; var s = true, x = null, V = false; and uses these shorthands instead; in conditions such as; if (someVariable == s) now; Google Analytics code defines it's own "s" variable; overriding the value "true"; and as you can see this causes a lot of problems. I don't want to change GA code; I just want Closure Compiler to quit renaming true etc. Externs do not work. Do you know any way to accomplish this?

    - by Riley
    Using Google Mini for a website that needs output from the Google Mini in a JSON/JSONP format for front-end querying purposes. Google Mini does publish an XML feed that could potentially be used by a middle process to convert to JSON/JSONP. Can Google Search Appliance / Mini output to JSON/JSONP using a plug-in, modification to an XSLT template, or other unknown method?

  • Shadowbox.js and dailymotion videos

    - by Greenie
    Hi there. I have a site set up with some thumbs and links to videos hosted on vimeo. I show them in a overlay using shadowbox.js. This works perfect. Now I want to add a video hosted on dailymotion, but it doesn't work. The working link to vimeo video: <a rel="shadowbox;height=636;width=956" href="http://vimeo.com/moogaloop.swf?clip_id=11377863&server=vimeo.com&show_title=1&show_byline=1&show_portrait=1&color=00ADEF&fullscreen=1" class="player_text">thumbnail here</a> The non working link to dailymotion video: <a rel="shadowbox;height=636;width=956" href="http://www.dailymotion.com/swf/xd6g8y?related=0&autoplay=1" class="player_text">thumbnail here</a> When the href is pasted in a browser, both links work fine. Both are played in a swf as far as I can see. So I can't see why shadowbox won't show it. Unless its a permission problem on the dailymotion video. Anyone know what I'm doing wrong?

  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."

  • jQuery - Callback failing if there is no options parameter

    - by user249950
    Hi, I'm attempting to build a simple plugin like this (function($) { $.fn.gpSlideOut = function(options, callback) { // default options - these are used when no others are specified $.fn.gpSlideOut.defaults = { fadeToColour: "#ffffb3", fadeToColourSpeed: 500, slideUpSpeed: 400 }; // build main options before element iteration var o = $.extend({}, $.fn.gpSlideOut.defaults, options); this.each(function() { $(this) .animate({backgroundColor: o.fadeToColour},o.fadeToColourSpeed) .slideUp(o.SlideUpSpeed, function(){ if (typeof callback == 'function') { // make sure the callback is a function callback.call(this); // brings the scope to the callback } }); }); return this; }; // invoke the function we just created passing it the jQuery object })(jQuery); The confusion I'm having is that normally on jQuery plugins you can call something like this: $(this_moveable_item).gpSlideOut(function() { // Do stuff }); Without the options parameter, but it misses the callback if I do it like that so I have to always have var options = {} $(this_moveable_item).gpSlideOut(options, function() { // Do stuff }); Even if I only want to use the defaults. Is there anyway to make sure the callback function is called whether or not the options parameter is there? Cheers.

  • Why does my Ajax function returns my entire code?

    - by JDelage
    I'm playing with sample code from the book "Head first Ajax". Here are the salient pieces of code: Index.php - html piece: <body> <div id="wrapper"> <div id="thumbnailPane"> <img src="images/itemGuitar.jpg" width="301" height="105" alt="guitar" title="itemGuitar" id="itemGuitar" onclick="getDetails(this)"/> <img src="images/itemShades.jpg" alt="sunglasses" width="301" height="88" title="itemShades" id="itemShades" onclick="getDetails(this)" /> <img src="images/itemCowbell.jpg" alt="cowbell" width="301" height="126" title="itemCowbell" id="itemCowbell" onclick="getDetails(this)" /> <img src="images/itemHat.jpg" alt="hat" width="300" height="152" title="itemHat" id="itemHat" onclick="getDetails(this)" /> </div> <div id="detailsPane"> <img src="images/blank-detail.jpg" width="346" height="153" id="itemDetail" /> <div id="description"></div> </div> </div> </body> Index.php - script: function getDetails(img){ var title = img.title; request = createRequest(); if (request == null) { alert("Unable to create request"); return; } var url= "getDetails.php?ImageID=" + escape(title); request.open("GET", url, true); request.onreadystatechange = displayDetails; request.send(null); } function displayDetails() { if (request.readyState == 4) { if (request.status == 200) { detailDiv = document.getElementById("description"); detailDiv.innerHTML = request.responseText; }else{ return; } }else{ return; } request.send(null); } And Index.php: <?php $details = array ( 'itemGuitar' => "<p>Pete Townshend once played this guitar while his own axe was in the shop having bits of drumkit removed from it.</p>", 'itemShades' => "<p>Yoko Ono's sunglasses. While perhaps not valued much by Beatles fans, this pair is rumored to have been licked by John Lennon.</p>", 'itemCowbell' => "<p>Remember the famous \"more cowbell\" skit from Saturday Night Live? Well, this is the actual cowbell.</p>", 'itemHat' => "<p>Michael Jackson's hat, as worn in the \"Billie Jean\" video. Not really rock memorabilia, but it smells better than Slash's tophat.</p>" ); if (isset($_REQUEST['ImageID'])){echo $details[$_REQUEST['ImageID']];} ?> All this code does is that when someone clicks on a thumbnail, a corresponding text description appears on the page. Here is my question. I have tried to bring the getDetails.php code inside Index.php, and modify the getDetails function so that the var url be "Index.php?ImageID="... . When I do that, I get the following problem: the function does not display the snippet of text in the array, as it should. Instead it reproduces the entire code - the webpage, etc - and then at the bottom the expected snippet of text. Why is that?

  • Dynamically Resizing an Iframe

    - by regex
    Hello All, I can see that this question has been asked several times, but none of the proposed solutions seem to work for the site I am building, so I am reopening the thread. I am attempting to size an iframe based on the height of it's content. Both the page that contains the iframe and it's source page exist on the same domain. I have tried the proposed solutions in each of the following threads: Resize iframe height according to content height in it Resizing an iframe based on content I believe that the solutions above are not working because of when the reference to body.clientHeight is made, the browser has not actually determined the height of the document. Here is the code I am using: var ifmBlue = document.getElementById("ifmBlue"); ifmBlue.onload = resizeIframe; function resizeIframe() { var ifmBlue = document.getElementById("ifmBluePill"); var ifmDiv = ifmBlue.contentDocument.getElementById("main"); var height = ifmDiv.clientHeight; ifmBlue.style.height = (ifmBlue.contentDocument.body.scrollHeight || ifmBlue.contentDocument.body.offsetHeight || ifmBlue.contentDocument.body.parentNode.clientHeight || height || 500) + 5 + 'px'; } If I debug the script using fire debug, the client height of the iframe.contentDocument's main div is 0. Additionally, body.offsetHieght, & body.scrollHeight are 0. However, after the script is finished running, if I inspect the DOM of the HTML iframe element (using fire debug) I can see that the body's clientHeight is 456 and the inner div's clientHeight is 742. This leads me to believe that these values are not yet set when iframe.onload is fired. So, per one of the threads above, I moved the code into the body.onload event handler of the iframe's source page. This solution also did not work. Any help you can provide is much appreciated. Thanks, CJ

  • How can I work around SQL Server - Inline Table Value Function execution plan variation based on par

    - by Ovidiu Pacurar
    Here is the situation: I have a table value function with a datetime parameter ,lest's say tdf(p_date) , that filters about two million rows selecting those with column date smaller than p_date and computes some aggregate values on other columns. It works great but if p_date is a custom scalar value function (returning the end of day in my case) the execution plan is altered an the query goes from 1 sec to 1 minute execution time. A proof of concept table - 1K products, 2M rows: CREATE TABLE [dbo].[POC]( [Date] [datetime] NOT NULL, [idProduct] [int] NOT NULL, [Quantity] [int] NOT NULL ) ON [PRIMARY] The inline table value function: CREATE FUNCTION tdf (@p_date datetime) RETURNS TABLE AS RETURN ( SELECT idProduct, SUM(Quantity) AS TotalQuantity, max(Date) as LastDate FROM POC WHERE (Date < @p_date) GROUP BY idProduct ) The scalar value function: CREATE FUNCTION [dbo].[EndOfDay] (@date datetime) RETURNS datetime AS BEGIN DECLARE @res datetime SET @res=dateadd(second, -1, dateadd(day, 1, dateadd(ms, -datepart(ms, @date), dateadd(ss, -datepart(ss, @date), dateadd(mi,- datepart(mi,@date), dateadd(hh, -datepart(hh, @date), @date)))))) RETURN @res END Query 1 - Working great SELECT * FROM [dbo].[tdf] (getdate()) The end of execution plan: Stream Aggregate Cost 13% <--- Clustered Index Scan Cost 86% Query 2 - Not so great SELECT * FROM [dbo].[tdf] (dbo.EndOfDay(getdate())) The end of execution plan: Stream Aggregate Cost 4% <--- Filter Cost 12% <--- Clustered Index Scan Cost 86%

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • Looking for design/architecture suggestions for a simple HTML game.

    - by z-boss
    Imagine that HTML page is a game surface (see picture). User can have n number of boards (blue divs) on his page. Each board can be moved, re-sized, relabeled, created new and removed. Inside each board there are m number of figures (purple divs). Each of these user can move inside the board or to another board, re-size, change color and label, delete, add new. The goal of the game is not important, but let's say it is to rearrange figures in a certain way so that they disappear. But the goal of the programmer is to save the whole game surface in the database for every user of the site, and to load it later when he returns. So, how do I go about data exchange between client and the database? I'll give my idea in one of the answers.

  • Air XmlHttpRequest time out if remote server is offline?

    - by Seth
    I'm writing an AIR application that communicates with a server via XmlHttpRequest. The problem that I'm having is that if the server is unreachable, my asynchronous XmlHttpRequest never seems to fail. My onreadystatechange handler detects the OPENED state, but nothing else. Is there a way to make the XmlHttpRequest time out? Do I have to do something silly like using setTimeout() to wait a while then abort() if the connection isn't established? Edit: Found this, but in my testing, wrapping my xmlhttprequest.send() in a try/catch block or setting a value on xmlhttprequest.timeout (or TimeOut or timeOut) doesn't have any affect.

  • Read a variable from a variable cookie jquerycookie.

    - by Ozaki
    TLDR How could I tell "page.html" which one of 3 or so cookies to look at when the cookie is set on the previous page? Currently: When a link is clicked save text of link to cookie When "page.html" is loaded get the value of the cookie Loads the getjson call as per value of the cookie. E.g: <a href="page.html">link1</a> -c1 <a href="page.html">link2</a> -c2 <a href="page.html">link3</a> -c3 See previous discussion here Now that is all good and well apart from the fact if I were to say open them in multiple tabs. It changes the cookie and correctly loads the right data. But if I were to refresh one of these tabs it will load the most recently open data rather than what it should be. So if I were to save a cookie as c1 with a value of link1 c2 with a value of link2 c3 with a value of link3 How could I tell "page.html" which cookie it should be looking at, therefore not breaking the back/forward/refresh buttons on the browser when multiple tabs are open?
