  • Best way of showing more results with javascript/css

    - by Ricardo Neves
    I'm developing a website and i'm having troubles showing the search results to the user the way I want. Basically, after the user search, the page makes a couple of ajax requests and as soon as a response arrive it appends the info to a specific element on my page. Each results is shown as a line... The problem is that in most case there are going to be more than 1000 results and this would make the page have a large scroll. My idea was to show only the first 15 results and when the user clicks "show more" the element would expand and show the next 15 results and so on... This would be easier to do if the website wasn't responsive, but because it is I can't find the proper way of implementing what I want without lowering the website perfomance. I have "2 ideas": The first is by using something like #element .div:nth-child(-n+15) on my css and figure a way of changing the "15" to how much results I want to show... I don't know if this can be done. Is it possible to call css rules with parameters? Maybe with less css? The second option is probably a bad option if i don't want to lower the website performance. Using javascript I would check if there is a specific css class(like .show-15 .show30 .show45) and add that class to my element and if it don't exist, create it somehow.. Any help would be appreciated.

  • IE7 & IE8 error executing function with ajax

    - by Yahreen
    I am loading an ajax page which executes an HTML5 video player script. The function for the Flash fallback is html5media(); : //Load 1st Case Study $("#splash").live('click', function (e) { $(this).fadeOut('slow', function () { $('#case-studies').load('case-study-1.html', function() { html5media(); //initiate Flash fallback }).fadeIn(); }); e.preventDefault(); }); This initial page load works fine in IE7 & IE8. The problem is once this page is loaded, there are links to 4 more videos which are loaded in again using ajax. I use this function: //Switcher function csClients(url, client) { $("#case-studies").fadeOut('slow', function() { $('#case-studies').load(url, function () { html5media(); //initiate Flash fallback }).fadeIn(); }); } //Page Loader $("#cs-client-list li.client1 a").live('click', function(e) { csClients('case-study-1.html', 'client1'); e.preventDefault(); }); Originally I was using return false; but none of the sub-page Flash videos would load in IE7. When I switched to preventDefault, the videos loaded in IE7 but still not in IE8. I also get a weird error in both IE7 & IE8 with no helpful feedback: Error on Page: Unspecified error. / (Line 49) Code: 0 (Char 5) URI: http://www.mysite.com This is line 49 in my index page: <section id="case-studies" class="main-section"> I have a feeling it has to do with calling html5media(); too many times? At a loss...

  • Want to set 'src' of script to my IP.

    - by Ozaki
    I have a script that links to the server I am hosting (IP can change) usually I would just use for links: var url ='http://' + window.location.hostname + 'end of url'; But in this case it isnt appearing to be so easy. I have tried: (1) $('#scriptid').attr('src', url); as well as: (2) var script = document.createElement( 'script' ); script.type = 'text/javascript'; script.src = url; $("#insert").append( script ); Now case (2) works loads the script runs the script. But when at the end of my script it hits the 'write data' it decides to replace the entire page with just the data. Any idea on how I can do this?

  • Get computed font size for DOM element in JS

    - by Pekka
    Is it possible to detect the computed font-size of a DOM element, taking into consideration generic settings made elsewhere (In the body tag for example), inherited values, and so on? A framework-independent approach would be nice, as I'm working on a script that should work standalone, but that is not a requirement of course. Background: I'm trying to tweak CKEditor's font selector plugin (source here) so that it always shows the font size of the current cursor position (as opposed to only when within a span that has an explicit font-size set, which is the current behaviour).

My function is: getObjName(objId){ var objName =""; $.ajax( { type : "GET", url : "Object", dataType: 'json', data : "objId="+objId, success : function(data) { objName = data; } }); return objName; } I am trying to call it and assign it to a variable with: var objName = getObjName(objId); However Eclipse is telling me that "there is no such function getObjName() defined"

  • External Javascript file fails to receive variables from previous javascript block

    - by Franc
    I've been searching the net for several hours and can't find an answer in the whole "external js file"-jungle. I hope you guys can help! In short: My external javascript file doesn't seem to get the variables which I defined in the main.php file.. On main.php I define php variables and "transform" them into javascript variables <head>... <script type="text/javascript"> var phpmain_img = <?php echo json_encode($main_img); ?>; var phpvar1_large = <?php echo json_encode($var1_large); ?>; var phpvar2_large = <?php echo json_encode($var2_large); ?>; var phpvar3_large = <?php echo json_encode($var3_large); ?>; var phpvar4_large = <?php echo json_encode($var4_large); ?>; </script> ... <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> In my ext.js file I want to process those variables. In the ext.js file I defined a the function swapImage() that will be used back in the main PHP: var imgArray = new Array( phpmain_img, phpvar1_large, phpvar2_large, phpvar3_large ); function swapImage(imgID) { var theImage = document.getElementById('theImage'); var newImg; newImg = imgArray[imgID]; theImage.src = newImg; } function preloadImages() { for(var i = 0; i < imgArray.length; i++) { var tmpImg = new Image; tmpImg.src = imgArray[i]; } } Result: The swapImage() in the main.php... doesnt work <div id="image"> <img id="theImage" src="<?=$main_img; ?>" alt="" /> </div> <div id="thumbs"> <?php echo "<img src=\"<$main_img_small\" alt=\"\" onmouseover=\"swapImage(0);\">"; echo "<img src=\"$var1_small\" alt=\"\" onmouseover=\"swapImage(1);\">"; echo "<img src=\"$var2_small\" alt=\"\" onmouseover=\"swapImage(2);\">"; echo "<img src=\"$var3_small\" alt=\"\" onmouseover=\"swapImage(3);\">"; ?> <br /> </div> Any help is greatly appreciated! UPDATE: I don't get a specific error, the swapImage functions doesn't work at mouseover. However, I tried to output the variables with e.g. document.write(phpimg_main) but nothing appears which makes me believe that there's something wrong with the handing over of the variables... here's the source code browser output `<html> <head> <link href="../demo.css" rel="stylesheet" type="text/css" /> <style type="text/css"> .... </style> <script type="text/javascript"> var phpmain_img = {"0":"http:\/\/path\/to\/main\/image.jpg"}; var phpvar1_large = {"0":"http:\/\/path\/to\/image1.jpg"}; var phpvar2_large = {"0":"http:\/\/path\/to\/image2.jpg"}; var phpvar3_large = null; var phpvar4_large = null; </script> <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> <body onload="preloadImages()"> <div id="image"> <img id="theImage" src="http://path-to-main-image.jpg" alt="" /> </div> <div id="thumbs"> <img src="http://path-to-main-image.jpg" alt="" onmouseover="swapImage(0);"><img src="http://path-to-image1.jpg" alt="" onmouseover="swapImage(1);"><img src="http://path-to-image2.jpg" alt="" onmouseover="swapImage(2);"> <br /> </div> </body> `

  • How to filter using a dropdown in Knockout

    - by user517406
    I have just started using Knockout and I want to filter my data that I am displaying in my UI by selecting an item from a dropdown. I have got so far, but I cannot get the selected value from my dropdown yet, and then after that I need to actually filter the data displayed based upon that value. Here is my code so far : @model Models.Fixture @{ ViewBag.Title = "Fixtures"; Layout = "~/Areas/Development/Views/Shared/_Layout.cshtml"; } @Scripts.Render("~/bundles/jqueryval") <script type="text/javascript" src="@Url.Content("~/Scripts/knockout-2.1.0.js")"></script> <script type="text/javascript"> function FixturesViewModel() { var self = this; var baseUri = '@ViewBag.ApiUrl'; self.fixtures = ko.observableArray(); self.teams = ko.observableArray(); self.update = function (fixture) { $.ajax({ type: "PUT", url: baseUri + '/' + fixture.Id, data: fixture }); }; self.sortByAwayTeamScore = function () { this.fixtures.sort(function(a, b) { return a.AwayTeamScore < b.AwayTeamScore ? -1 : 1; }); }; self.select = function (team) { }; $.getJSON("/api/fixture", self.fixtures); $.getJSON("/api/team", self.teams); } $(document).ready(function () { ko.applyBindings(new FixturesViewModel()); }); </script> <div class="content"> <div> <table><tr><td><select data-bind="options: teams, optionsText: 'TeamName', optionsCaption: 'Select...', optionsValue: 'TeamId', click: $root.select"> </select></td></tr></table> <table class="details ui-widget-content"> <thead> <tr><td>FixtureId</td><td>Season</td><td>Week</td><td>AwayTeam</td><td><a id="header" data-bind='click: sortByAwayTeamScore'>AwayTeamScore</a></td><td>HomeTeam</td><td>HomeTeamScore</td></tr> </thead> <tbody data-bind="foreach: fixtures"> <tr> <td><span data-bind="text: $data.Id"></span></td> <td><span data-bind="text: $data.Season"></span></td> <td><span data-bind="text: $data.Week"></span></td> <td><span data-bind="text: $data.AwayTeamName"></span></td> <td><input type="text" data-bind="value: $data.AwayTeamScore"/></td> <td><span data-bind="text: $data.HomeTeamName"></span></td> <td><input type="text" data-bind="value: $data.HomeTeamScore"/></td> <td><input type="button" value="Update" data-bind="click: $root.update"/></td> </tr> </tbody> </table> </div> </div> Can anybody please advise on this?

When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?

  • How to initiate JavaScript Callback with MVC2 using RenderAction

    I am building a dashboard where I am iterating through a list of controls to render, and I need to initiate a general callback both after each control and after they are all completed. I was curious what the best way to handle this is. I can get the control specific callback fired off by placing myUserControlCallback(); in the user control itself. I'm just not sure how to run something like allControlsRendered();. Any ideas?

  • Why doesn't the .click() not work in this instance?

    - by Deshiknaves
    Basically what this does is fadeIn pre-existing divs and then loads an image. When the image is loaded it then appends that into one of the pre-existing divs. Then it appends a new div with an id of xButton. Then later it $('#xButton').click() should hide the 3 divs. However it just doesn't work. If I change the click() to either #modalImage or #overlay, it works but just not for the #xButton. I would really like to figure out why its not working and how I should be doing this instead. Thanks. $(function(){ $('#container a').click(function(e){ e.preventDefault(); var id = $(this).attr('href'), img = new Image(); $('#overlay').fadeIn(function(){ $('#modalImage').fadeIn(); }); $(img).load(function(){ $(this).hide(); $('#modalImage').removeClass('loader').append(this); $(this).fadeIn(function(){ var ih = $(this).outerHeight(), iw = $(this).outerWidth(), newH = ($(window).height()/10)*7, newW = ($(window).width()/10)*7; if (ih >= iw && ih >= newH) { $(this).css('height',newH + 'px'); $(this).css('width', 'auto'); } else if (ih >= iw && newH > ih) { $(this).css('height', ih + 'px'); $(this).css('width', 'auto'); } else if (iw > ih && iw >= newW) { if ((newW / (iw / ih)) > newH) { $(this).css('width', 'auto'); $(this).css('height', newH + 'px'); } else { $(this).css('width', newW + 'px'); $(this).css('height', 'auto'); } } else { $(this).css('width', iw + 'px'); $(this).css('height', 'auto'); } var padW = ($(window).width() - $(this).outerWidth()) / 2, padH = ($(window).height() - $(this).outerHeight()) / 2; console.log (padH + ' ' + padW); $(this).css('top', padH); $(this).css('left', padW); if($('#overlay').is(":visible") == true) { ih = ih + 4; $('<div id="xButton">x</div>').appendTo('#modalImage'); if (padH >= 0) { $('#xButton').css('top', padH - 4).css('right', padW - 65); } else { $('#xButton').css('top', '20px').css('right', padW - 65); } } }); }).attr('src', id); }); $('#xButton').click(function(){ $(this).hide(); $('#overlay').fadeOut(function(){ $('#modalImage img').css('top', '-9999px').remove(); $('#xButton').remove(); $('#modalImage').addClass('loader'); }); }); });

  • Remember (persist) the filter, sort order and current page of jqGrid

    - by Jimbo
    My application users asked if it were possible for pages that contain a jqGrid to remember the filter, sort order and current page of the grid (because when they click a grid item to carry out a task and then go back to it they'd like it to be "as they left it") Cookies seem to be the way forward, but how to get the page to load these and set them in the grid before it makes its first data request is a little beyond me at this stage. Does anyone have any experience with this kind of thing with jqGrid? Thanks!

  • How to decide if a parameter is the click event

    - by sameold
    I have a function which can be called by either a click event or directly. When I call it directly, I need pass it a data parameter, so I've defined the function to accept a parameter to account for the direct call with the parameter. function myFunc(param){ } Within the function, I need to differentiate whether the function was called directly or from the click event, so what I thought I could simply check if param is set. If it's set, then the function is called directly. If it's not set, then it's called from the click event. The problem is that a click event by default passes an event object. So even when the function is called by the click event, param won't be null. So is there a way to check whether the param passed is the click event?
