  • Cannot position Google +1 button with CSS?

    - by Bogdan Protsenko
    I'm having some trouble positioning the Google +1 button on my website. The div is as follows: <div class="g-plusone"></div> The CSS I'm using is pretty simple: .g-plusone { position: absolute; top:95px; left:715px; } I know for a fact that the div in question is being accessed. What's strange is that other social sharing buttons, such as the FB like below follow the same syntax and are positioned perfectly. .fb-like { position: absolute; top:62px; left:715px; } Any ideas?

    Hello everybody! I am trying to study some java and cannot get my head around this question! Any help would be really appreciated and would help me in further studies! Thank you so much in advance! Eoin from Dublin, Ireland. ArrayList of Objects Write a program which works out which is the lowest priced computer in an ArrayList of computer objects. You should have two classes, one called ComputerTest, and the other called Computer. In the ComputerTest class you should: Have a main method which declares an ArrayList of type Computer called computerList, each element of which represents a computer. Initialise the first three entries of the ArrayList Call a static method which prints out the lowest price computer, called lowestPrice The parameter of this method is (i) an ArrayList of type Computer i.e. ArrayList data Sample output: The lowest priced computer is the Cheapo400 at 399 euro.

  • convert list of relative widths to pixel widths

    - by mkoryak
    This is a code review question more then anything. I have the following problem: Given a list of relative widths (no unit whatsoever, just all relative to each other), generate a list of pixel widths so that these pixel widths have the same proportions as the original list. input: list of proportions, total pixel width. output: list of pixel widths, where each width is an int, and the sum of these equals the total width. Code: var sizes = "1,2,3,5,7,10".split(","); //initial proportions var totalWidth = 1024; // total pixel width var sizesTotal = 0; for (var i = 0; i < sizes.length; i++) { sizesTotal += parseInt(sizes[i], 10); } if(sizesTotal != 100){ var totalLeft = 100;; for (var i = 0; i < sizes.length; i++) { sizes[i] = Math.floor(parseInt(sizes[i], 10) / sizesTotal * 100); totalLeft -= sizes[i]; } sizes[sizes.lengh - 1] = totalLeft; } totalLeft = totalWidth; for (var i = 0; i < sizes.length; i++) { widths[i] = Math.floor(totalWidth / 100 * sizes[i]) totalLeft -= widths[i]; } widths[sizes.lenght - 1] = totalLeft; //return widths which contains a list of INT pixel sizes

  • How do I convert an AMD module from a singleton to an instance?

    - by Jamie Ide
    I'm trying to convert a working Durandal view model module from a singleton to an instance. The original working version followed this pattern: define(['knockout'], function(ko) { var vm = { activate: activate, companyId: null; company: ko.observable({}) }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The new version exports a function so that I get a new instance on every request... define(['knockout'], function(ko) { var vm = function() { activate = activate; companyId = null; company = ko.observable({}); }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The error I'm getting is "object function () [...function signature...] has no method company on the line vm.company(data);. What am I doing wrong? Why can I set the property but can't access the knockout observable? How should I refactor the original code so that I get a new instance on every request? My efforts to simplify the code for this question hid the actual problem. My real code was using Q promises and calling two methods with Q.All. Since Q is in the global namespace, it couldn't resolve my viewmodel after converting to a function. Passing the view model to the methods called by Q resolved the problem.

  • Showing a loading spinner only if the data has not been cached.

    - by Aaron Mc Adam
    Hi guys, Currently, my code shows a loading spinner gif, returns the data and caches it. However, once the data has been cached, there is a flicker of the loading gif for a split second before the data gets loaded in. It's distracting and I'd like to get rid of it. I think I'm using the wrong method in the beforeSend function here: $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : page }, beforeSend : function() { $('.jPag-pages li:not(.cached)').each(function (i) { $('#searchResults').html('<p id="loader">Loading...<img src="../assets/images/ajax-loader.gif" alt="Loading..." /></p>'); }); }, success : function(data) { $('.jPag-current').parent().addClass('cached'); $('#searchResults').replaceWith($(data).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); } });

  • Prototype mouseleave for two connected elements

    - by TenJack
    I have created a small navigation element that is positioned right on top of another element. It is only shown when a user mousenters/mouseovers the main element. I am having some trouble with the prototype. I would like this small nav element to be hidden when a user mouses out of the main box, but I would also like the small nav element to remain visible if a user mouses out of the main box but mouses into the small nav at the same time. This is my attempt so far with some pseudo-code to hopefully explain: $('main_box').observe('mouseenter', function(){ $('small_div').show() }) $('main_box').observe('mouseleave', function(){ if this element is $('small_div') then Event.stop() $('small_div').observe('mouseleave', function(){ if this element is $('main_box') Event.stop observe $('main_box') mouseleave else $('small_div').hide(); }) else $('small_div').hide(); }) The main thing I'm having trouble with is figuring out what element the mouse is over at a given point in time. Is there a way to do something like: on mouseleave do blah unless the mouse is over a specific element then do not do blah?

  • Resizing image to fit its container

    - by jack moore
    #foo {width: 300px; height: 400px; overflow: hidden;} <div id="foo"></div> this.someimage = randomImageUrl; $("foo").innerHTML = "<img src='"+this.someimage+"' class='fooimage' />"; Now, the picture could be 200x200 or 1100x400 ... it's totally random. I can just stretch it (or reduce its size) by using: .fooimage {width: 300px; height: 400px;} $("foo").innerHTML = "<img src='"+this.someimage+"' class='fooimage' />"; Or I could test its size: imgHeight = newImg.height; imgWidth = newImg.width; ... and maybe something like this: if(imgHeight >400){ $("foo").innerHTML = "<img src='"+this.someimage+"' height='400' />"; } and browsers will do the rest. But there must be something better. Any ideas? Thanks! :)

  • Move rotating image along Canvas

    - by fatnic
    Hi. I've managed to make an image rotate on my canvas. And I've managed to make an image move along the canvas. My problem now is making it do both. I have got it working but I seems a bit like a hack. I've posted a demo online Here's the code. var cnv = document.getElementById("drawing"); var c = cnv.getContext('2d'); var image = new Image(); image.src = 'images/spaceship.png'; var imgWidth = image.width; var imgHeight = image.height; var i=0; function animate() { c.clearRect(0,0,640,480); c.save(); c.translate(-(imgWidth/2)+i,200); c.rotate(i * Math.PI/180); c.translate(-(imgWidth/2),-(imgHeight/2)); c.drawImage(image, 0, 0); c.restore(); (i==640+imgWidth) ? i=0: i+=2; }; setInterval(animate, 1); I think my problem is I'm not understanding the translate() method properly. Is this the correct way to do it or am I competely way off?

  • Why does an onclick property set with setAttribute fail to work in IE?

    - by Aeon
    Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

  • How to use jQuery to assign a class to only one radio button in a group when user clicks on it?

    - by xraminx
    I have the following markup. I would like to add class_A to <p class="subitem-text"> (that holds the radio button and the label) when user clicks on the <input> or <label>. If user clicks some other radio-button/label in the same group, I would like to add class_A to this radio-button's parent paragraph and remove class_A from any other paragraph that hold radio-buttons/labels in that group. Effectively, in each <li>, only one <p class="subitem-text"> should have class_A added to it. Is there a jQuery plug-in that does this? Or is there a simple trick that can do this? <ul> <li> <div class="myitem-wrapper" id="10"> <div class="myitem clearfix"> <span class="number">1</span> <div class="item-text">Some text here </div> </div> <p class="subitem-text"> <input type="radio" name="10" value="15" id="99"> <label for="99">First subitem </label> </p> <p class="subitem-text"> <input type="radio" name="10" value="77" id="21"> <label for="21">Second subitem</label> </p> </div> </li> <li> <div class="myitem-wrapper" id="11"> <div class="myitem clearfix"> <span class="number">2</span> <div class="item-text">Some other text here ... </div> </div> <p class="subitem-text"> <input type="radio" name="11" value="32" id="201"> <label for="201">First subitem ... </label> </p> <p class="subitem-text"> <input type="radio" name="11" value="68" id="205"> <label for="205">Second subitem ...</label> </p> <p class="subitem-text"> <input type="radio" name="11" value="160" id="206"> <label for="206">Third subitem ...</label> </p> </div> </li>

  • Java-script object - get variable name

    - by Mikk
    Hi, To begin with, I'm not even sure, if it is the right way to do it. Let's say, i have script (jquery included) like this: foo = function() { this.bar = function() { alert('I\'m bar'); } this.test = function() { $('body').append('<a onclick="my_var.bar();">Click me</a>'); } this.test(); } var my_var = new foo(); Is there any way, i could make variable "my_var" dynamic inside function "foo". So I could do something like $('body').append('<a onclick="'+the_variable_which_im_assigned_to+'.bar();">Click me</a>'); Thank you

  • Capturing the contents of <select>

    - by joey mueller
    I'm trying to use a regular expression to capture the contents of all option values inside an HTML select element For example, in: <select name="test"> <option value="blah">one</option> <option value="mehh">two</option> <option value="rawr">three</option> </select> I'd like to capture one two and three into an array. My current code is var pages = responseDetails.responseText.match(/<select name="page" .+?>(?:\s*<option .+?>([^<]+)<\/option>)+\s*<\/select>/); for (var c = 0; c<pages.length; c++) { alert(pages[c]); } But it only captures the last value, in this case, "three". How can I modify this to capture all of them? Thanks!

  • Update table rows in a non-sequential way using the output of a php script

    - by moviemaniac
    Good evening everybody, this is my very first question and I hope I've done my search in stack's archive at best!!! I need to monitor several devices by querying theyr mysql database and gather some informations. Then these informations are presented to the operator in an html table. I have wrote a php script wich loads devices from a multidimensional array, loops through the array and gather data and create the table. The table structure is the following: <table id="monitoring" class="rt cf"> <thead class="cf"> <tr> <th>Device</th> <th>Company</th> <th>Data1</th> <th>Data2</th> <th>Data3</th> <th>Data4</th> <th>Data5</th> <th>Data6</th> <th>Data7</th> <th>Data8</th> <th>Data9</th> </tr> </thead> <tbody> <tr id="Device1"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> <tr id="Device2"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> <tr id="DeviceN"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> </tbody> </table> The above table is directly populated when I first load the page; then, with a very simple function, i update this table every minute without reloading the page: <script> var auto_refresh = setInterval( function() { jQuery("#monitoring").load('/overview.php').fadeIn("slow"); var UpdateTime= new Date(); var StrUpdateTime; StrUpdateTime= ('0' + UpdateTime.getHours()).slice(-2) + ':' + ('0' + UpdateTime.getMinutes()).slice(-2) + ':' + ('0' + UpdateTime.getSeconds()).slice(-2); jQuery("#progress").text("Updated on: " + StrUpdateTime); }, 60000); </script> The above code runs in a wordpress environment. It comes out that when devices are too much and internet connection is not that fast, the script times out, even if i dramatically increase the timeout period. So it is impossible even to load the page the first time... Therefore I would like to change my code so that I can handle each row as a single entity, with its own refresh period. So when the user first loads the page, he sees n rows (one per device) with the ajax loader image... then an update cycle should start independently for each row, so that the user sees data gathered from each database... then ajax loader when the script is trying to retrieve data, then the gathered data once it has been collected or an error message stating that it is not possible to gather data since hour xx:yy:zz. So rows updating should be somewhat independent from the others, like if each row updating was a single closed process. So that rows updating is not done sequentially from the first row to the last. I hope I've sufficiently detailed my problem. Currently I feel like I am at a dead-end. Could someone please show me somewhere to start from?

  • Array.sort Sorting Stability in Different Browsers

    - by Boushley
    What is the stability of Array.sort in different browsers. I know that the ECMA Script specification does not specify which algorithm to use, nor does it specify whether the sort should be stable. I've found this information on for Firefox https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/Array/sort which specifies that firefox uses a stable sort. Does anyone know about IE 6/7/8, Chrome, Safari?

  • Downloading and Reading

    - by Jan Evans
    First I am a complete novice and need answers in plain and simple terms. I am trying to get the users manual for my Samsung galaxy s4 phone. Samsung "help" sent me a link to click but when I received it it was in Spanish tho the doc I'd said "english". The Samsung support line timed me out because I couldn't type fast enough when I told them I received it in Spanish. I explored the translator and didn't see how to translate a doc. Asked Google how to get the manual they gave a different doc I'd and sent it to clipboards. How can I read it? Now what? Tried to send this message and asking me for a tag and I have no idea what that means so I just clicked one. That's why I need the manual so desperately. It would be so much easier for me to get a paper copy of it but they want
