  • how to set href value on all elements with a given ID?

    - by dferraro
    I have several anchor tags on a page with the same id of 'hrefCompare'. I need to dynamically set the value of the href attribute on ALL of these a tags. I am currently trying to do this: $("#hrefCompare").attr("href", "foobar.com"); However, this only sets the very first anchor tag with that ID. there's 7 more on this page with the same id of 'hrefCompare'. How can I set all of the href values with that ID?

  • alternatives to eval for running remote code.

    - by Raynos
    Are there any alternatives to using eval to immediatly run remote & trusted javascript code. function load(filePath) { var o = $.ajax({ url: filePath, dataType: 'html', async: false }); eval(o.responseText); } load("somePath"); // run a function that relies on the code from o.responseText being loaded doSomethingWithCode(); I'm aware that synchronous loading of javascript is adviced againts. But if there is no choice are there any cross browser alternatives for the use of eval above. [Edit] To clarify in more detail the code being loaded is a self executing function. Which needs to execute before doSomethingWidthCode. It's also being loaded from the server on the same domain hence its trusted.

  • A standard event messaging system with AJAX?

    - by Gutzofter
    Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?

  • why do i lose my hidden field value?

    - by user517406
    Hi, I have some hidden fields on my page, all of which work fine apart from one. I am setting the value in document.ready, before calling buildGrid() : $(document).ready(function() { $.ajax( { type: "POST", url: "/CDServices.asmx/GetWeekEndingDates", data: "{}", dataType: "json", contentType: "application/json; charset=utf-8", success: function(msg) { //store default dates in hidden fields $("#<%=hdnCurrentDate.ClientID%>").val(msg.d.CurrentDate); $("#<%=hdnLastWeekEndingDate.ClientID%>").val(msg.d.LastWeekEndingDate); } }); buildGrid(); }); Yet in buildGrid, the value in the hidden field is empty : function buildGrid() { alert($("#<%=hdnLastWeekEndingDate.ClientID%>").val()); I call other functions on button clicks where the hidden field value is picked up fine, why does the value disappear here?

  • Created function not found

    - by skerit
    I'm trying to create a simple function, but at runtime firebug says the function does not exist. Here's the function code: <script type="text/javascript"> function load_qtip(apply_qtip_to) { $(apply_qtip_to).each(function(){ $(this).qtip( { content: { // Set the text to an image HTML string with the correct src URL to the loading image you want to use text: '<img class="throbber" src="/projects/qtip/images/throbber.gif" alt="Loading..." />', url: $(this).attr('rel'), // Use the rel attribute of each element for the url to load title: { text: 'Nieuwsbladshop.be - ' + $(this).attr('tooltip'), // Give the tooltip a title using each elements text //button: 'Sluiten' // Show a close link in the title } }, position: { corner: { target: 'bottomMiddle', // Position the tooltip above the link tooltip: 'topMiddle' }, adjust: { screen: true // Keep the tooltip on-screen at all times } }, show: { when: 'mouseover', solo: true // Only show one tooltip at a time }, hide: 'mouseout', style: { tip: true, // Apply a speech bubble tip to the tooltip at the designated tooltip corner border: { width: 0, radius: 4 }, name: 'light', // Use the default light style width: 250 // Set the tooltip width } }) } } </script> And I'm trying to call it here: <script type="text/javascript"> // Create the tooltips only on document load $(document).ready(function() { load_qtip('#shopcarousel a[rel]'); // Use the each() method to gain access to each elements attributes }); </script> What am I doing wrong?

  • How do you replace many characters in a regex?

    - by macca1
    I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?

    - by Xiao Jia
    I have the following HTML with CSS .container { overflow: scroll; } etc. <body> <div class="container"> <div id="markers"></div> <img id="map" src="/img/map.jpg"/> </div> </body> map.jpg is very large and I want to scroll to a fixed position like this: $(function(){ console.log($('.container').scrollTop()); $('.container').scrollTop(1000); console.log($('.container').scrollTop()); console.log($('.container').scrollLeft()); $('.container').scrollLeft(1750); console.log($('.container').scrollLeft()); }); scrollLeft works fine but scrollTop doesn't. Below is the console output. 0 0 0 1750 I've been searching for half an hour but still don't know how to fix it... UPDATE: CSS about .container #markers and #map .container { overflow: scroll; width: 100%; max-width: 100%; height: 100%; max-height: 100%; margin: 0; padding: 0; } #map { width: 5000px; max-width: 5000px; height: 2907px; max-height: 2907px; cursor: crosshair; } #markers { position: relative; top: 0; left: 0; width: 0; height: 0; margin: 0; padding: 0; }

  • Highlight DIV and dim the rest on mouseover

    - by Darren Sweeney
    I have a page full of DIVs which contain images. When I mouse over an image I can highlight it or add a shadow to accent it easily by adding class etc but is there a way to dim every other image instead. DIVs are loaded into DOM and I would like the DIV currently hovered over to retain 100% or 1 opacity and the rest of the DIVs on the page to fade to say 70% or 0.7 when one DIV is highlighted. Is this possible?

  • How to make an AJAX call immediately on document loading

    - by Ankur
    I want to execute an ajax call as soon as a document is loaded. What I am doing is loading a string that contains data that I will use for an autocomplete feature. This is what I have done, but it is not calling the servlet. I have removed the calls to the various JS scripts to make it clearer. I have done several similar AJAX calls in my code but usually triggered by a click event, I am not sure what the syntax for doing it as soon as the document loads, but I thought this would be it (but it's not): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script type="text/javascript"> $(document).ready(function(){ $.ajax({ type: "GET", url: "AutoComplete", dataType: 'json', data: queryString, success: function(data) { var dataArray = data; alert(dataArray); } }); $("#example").autocomplete(dataArray); }); </script> <title></title> </head> <body> API Reference: <form><input id="example"> (try "C" or "E")</form> </body> </html>

    - by blid
    I'll start with JS Fiddle: http://jsfiddle.net/zy2xy/4/ <div id="page" style="position: relative; background: #ccc; width: 500px; height: 600px;"> <div id="container" style="top: 50px; left: 100px; width: 200px; height: 200px; position: absolute; background: #fff;"> <img src="http://lorempixel.com/200/100/"> </div> </div>????????? I've got a whole page div #page, and inside that another div #container positioned absolute against #page. What I want to achieve, is to rotate image inside it 90deg, 180deg or 270deg but always move that image to top left corner of #container. I tried a little bit with transform-origin but I couldn't find any solution.

  • Rendering "partial" pages in ASP.Net? (without the <html> and such)

    - by Earlz
    Hello, I am trying to make use of jQueryUI AJAX tabs in my ASP.Net Webforms project. I have come up against a wall though. For AJAX, you must render only a partial page(no <html> and such elements) by an external URL. How would you best do this in ASP.Net? aspx files require things like a <html> and <head> tag so those wouldn't work so the only thing that comes to mind is using cumbersome ashx files. Am I just over thinking this? Is there an easier way?

  • Loading/Displaying large amount of data on webpage.

    - by jb
    I have a webpage which contains a table for displaying a large amount of data (on average from 2,000 to 10,000 rows). This page takes a long time to load/render. Which is understandable. The problem is, while the page is loading the PCs memory usage skyrockets (500mb on my test system is in use by iexplorer) and the whole PC grinds to a halt until it has finished, which can take a minute or two. IE hangs until it is complete, switching to another running program is the same. I need to fix this - and ideally i want to accomplish 2 things: 1) Load individual parts of the page seperately. So the page can render initially without the large data table. A loading div will be placed there until it is ready. 2) Dont use up so much memory or local resources while rendering - so at least they can use a different tab/application at the same time. How would I go about doing both or either of these? I'm an applications programmer by trade so i am still a little fizzy on the things I can do in a web environment. Cheers all.

  • Image not loading from cache after it's loaded in an iframe

    - by Amir
    I'm loading an image in an iframe and then (once the iframe is loaded) loading the image on the page. But most browsers seem to be loading the image twice. Why isn't the img tag being loading from the cache? Something like this: var loader = $('<iframe />').appendTo('body')[0]; loader.onload = function() { $('body').append('<img src="' + imgsrc + '" />'); }; loader.src = imgsrc; http://jsfiddle.net/amirshim/na3UA/ I'm using fiddler2 to see the network traffic.

  • adding a div with data()

    - by Dizzy Bryan High
    Hi people am generating a list of flash swfs, the information comes from an ajax call which returns a json object which i loop through to create the rows of data using my makeAppRow function. makeAppRow = function(myData){ var myStr = '<div class="fileEntry">' myStr = myStr +'<div class="appDate">'+dateFormat(myData.date_swf, "dS mmmm, yyyy, h:MM TT")+'</div>' myStr = myStr +'<div class="appName">'+myData.name_swf+'</div>' myStr = myStr +'<div class="appOptions" data>' myStr = myStr +'<div class="gotoAppBtn" data-options="'+myData+'">Open App</div>' myStr = myStr +'</div>' myStr = myStr +'</div>' $('#appData').append(myStr); } I need the json data to be attached to the gotoAppBtn so that when its clicked i can read in the data from the attached json object and use it in my click function, as you can see ive been trying to embed the data using the html5 data but i cant get it to work. <div class="gotoAppBtn" data-options="'+myData+'">Open App</div> i have a function so that when the button is clicked it loads in an swf. $('.gotoAppBtn').live('click', function(){ //alert('button clicked') var myData = $(this).data("options") alert('../userfiles/'+myData.id_ugp+'/'+myData.id_swf+'/'+myData.launchfile_swf+'') console.log(myData); var flashvars = {}; var params = {}; params.menu = "false"; params.quality = "best"; params.scale = "noscale"; var attributes = {}; attributes.id = "flashAppDisplay"; attributes.name = "flashAppDisplay"; swfobject.embedSWF( '../userfiles/'+myData.id_ugp+'/'+myData.id_swf+'/'+myData.launchfile_swf+'', 'flashAppDisplay', myData.width_swf, myData.height_swf, myData.version_swf ,"../FAVideo/expressInstall.swf", flashvars, params, attributes) }); but the data does not seem to be there, any pointers on where i am going wrong, or a better way to achive this???

  • Why is alert not run even though $.getJSON runs fine? (Callback not executed, even though the reques

    - by Emre Sevinç
    I have a snippet of code such as: $.getJSON("http://mysite.org/polls/saveLanguageTest?url=" + escape(window.location.href) + "&callback=?", function (data) { var serverResponse = data.result; console.log(serverResponse); alert(serverResponse); }); It works fine in the sense that it makes a cross-domain request to my server and the server saves the data as I expect. Unfortunately, even though the server saves data and sends back a response I just can't get any alert or the console.log run. Why may be that? The server side code is (if that is relevant): def saveLanguageTest(request): callback = request.GET.get('callback', '') person = Person(firstName = 'Anonymous', ipAddress = request.META['REMOTE_ADDR']) person.save() webPage = WebPage(url = request.GET.get('url')) webPage.save() langTest = LanguageTest(type = 'prepositionTest') langTest.person = person langTest.webPage = webPage langTest.save() req ['result'] = 'Your test is saved.' response = json.dumps(req) response = callback + '(' + response + ');' return HttpResponse(response, mimetype = "application/json") What am I missing? (I tried the same code both within my web pages and inside the Firebug and I always have the problem stated above.)

  • iPad doesn't trigger resize event going from vertical to horizontal?

    Has anyone noticed this behavior? I'm trying to write a script that will trigger upon a resize. It works fine on normal browsers, works fine on iPhone, but on iPad, will only trigger going from horizontal to vertical viewport, not vice versa. Here's the code: $(window).resize( function() { var agent=navigator.userAgent.toLowerCase(); var is_iphone = ((agent.indexOf('iphone') != -1)); var is_ipad = ((agent.indexOf('ipad') != -1)); if(is_iphone || is_ipad){ location.reload(true); } else { /* Do stuff. */ }; });
