  • Scrolling dynamically to the end of the page

    - by vanjadjurdjevic
    I have a link which animates some div's height when its hovered, but the div has a big height and it goes beyond the visible bottom-end of the screen. I have to scroll to see the data and when I scroll I leave the hover area and the div toggles it's height to 0px. How to automatically scroll to the end of the div when it toggles?

  • is it possible to start coda slider on a hidden div?

    - by andufo
    i have a div id=holder, and inside a coda slider. it works alright, but to avoid the flickering in certain browsers, i decided to make holder display:none, and then display:block on $(document).ready The problem is that, for some reason, when the parent div is display:none, the coda slider doesnt have any effect. any workarounds or ideas for this issue? thanks!

  • Rails: form input type and getting the filename

    - by Shyam
    Hi, As I am using Ruby on Rails to build an application, which only runs locally, I am lost in the woods (a nuby without a compass). I have a simple MVC application and my view is missing one thing I could really use. I want to select a local file just to retrieve it's filename. I know it's relatively easy to use the form tag helpers for uploading: <%= file_field 'upload', 'datafile' %></p> I wonder how I could get the filename from the selected file, without uploading the file.

  • window.open() in an iPad on load of a frame does not work

    - by user278859
    I am trying to modify a site that uses "Morten's JavaScript Tree Menu" to display PDFs in a frames set using the Adobe Reader plug-in. On the iPad the frame is useless, so I want to open the PDF in a new tab. Not wanting to mess with the tree menu I thought I could use JavaScript in the web page being opened in the viewer frame to open a new tab with the PDF. I am using window.open() in $(document).ready(function() to open the pdf in the new tab. The problem is that window.open() does not want to work in the iPad. The body of the HTML normally looks like this... <body> <object data="MypdfFileName.pdf#toolbar=1&amp;navpanes=1&amp;scrollbar=0&amp;page=1&amp;view=FitH" type="application/pdf" width="100%" height="100%"> </object> </body> I changed it to only have a div like this... <body> <div class="myviewer" ></div> </body> Then used the following script... $(document).ready(function() { var isMobile = { Android : function() { return navigator.userAgent.match(/Android/i) ? true : false; }, BlackBerry : function() { return navigator.userAgent.match(/BlackBerry/i) ? true : false; }, iOS : function() { return navigator.userAgent.match(/iPhone|iPad|iPod/i) ? true : false; }, Windows : function() { return navigator.userAgent.match(/IEMobile/i) ? true : false; }, any : function() { return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Windows()); } }; if(isMobile.any()) { var file = "MypdfFileName.pdf"; window.open(file); }else { var markup = "<object data='MypdfFileName.pdf#toolbar=1&amp;navpanes=1&amp;scrollbar=0&amp;page=1&amp;view=FitH' type='application/pdf' width='100%' height='100%'></object>"; $('.myviewer').append(markup); }; }); Everthing works except for window.open() on the iPad. If I switch things around widow.open() works fine on a computer. In another project I am using window.open() successfully on the iPad from an onclick function. I tried using a timer function. I also tried adding an onclick function to the div and posting a click event. In both cases they worked on a computer but not an iPad. I am stumped. I know it would make more sense to handle the ipad in the tree menu frame, but that code is so complex I can't figure out where to put/modify the onclick event. Is there a way to change the object so that it opens in a new tab? Is anyone familiar enough with Mortens Tree Menu code that can tell me how to channge the on click event so that it opens the pdf in a new tab instead of opening a page in the frame? Thanks

  • 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.

  • Why doesn't $("#RadioButtons:checked").val() work in IE?

    - by Randy Heaps
    Why doesn't $("#RadioButtons:checked").val() - id selector - work in Internet Explorer but $("input:radio[name='RadioButtons']:checked").val() - name selector - does? <input name="RadioButtons" id="RadioButtons" type="radio" value="1" checked> <input name="RadioButtons" id="RadioButtons" type="radio" value="2"> <script> alert($("#RadioButtons:checked").val()); alert($("input:radio[name='RadioButtons']:checked").val()); </script>

  • How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • On Click alert if $.get returns a value, if not, submit the form

    - by bradenkeith
    If the submit button is clicked, prevent the default action and see if the field 'account_name' is already in use. If the $.get() returns a result, alert the user of the results. If it doesn't, submit form with id="add_account_form". My problem is that my else{} statement is not submitting the form. I get no response when submit is clicked & there is no value returned. Also I would like to change my code where it goes $("#add_account_form").submit(..) instead of .click() however, would that cause a problem when trying to submit the form later in the script? <script type="text/javascript"> $(document).ready( function () { $("#submit").click( function () { var account_name = $("input[name=account_name]").val(); $.get( "'.url::site("ajax/check_account_name").'", {account_name: account_name}, function(data){ if(data.length > 0){ confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." ); }else{ $("#add_account_form").submit(); } }); return false; }); }); </script> <p> <input type="submit" id="submit" class="submit small" name="submit" value="Submit" /> </p> </form> Thanks for your help. EDIT So anyone who runs into my problems, it's that $.get() is asynchronous, so it will always return false, or true depending on what submitForm is defined as. $.ajax() however, allows async to be set as false, which allows the function to finish before moving on. See what I mean: $(document).ready( function () { $("#add_account_form").submit( function () { var submitForm = true; var account_name = $("input[name=account_name]").val(); $.ajax({ type: "GET", async: false, url: "'.url::site("ajax/check_account_name").'", data: ({account_name: account_name}), success: function(data){ if(data.length > 0){ if(!confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." )){ submitForm = false; } } } }); if (submitForm == false ) { return false; } }); }); Thanks for your help @Dan

  • Calling a function when a scrollbar appears in an IFrame

    - by chris
    I got an IFrame, in the onload event i set the height of the frame: function resizeFrame() { $("#iframeID").height($("#iframeID").contents().find("body").outerHeight(true)); } Problem is: When the content of the frame is increasing without a postback (javascript or Async Postback with Ajax), a scrollbar appears. I found a solution for Firefox: document.getElementById("iframeID").contentWindow.addEventListener("overflow", resizeFrame, false); But i can't find a solution for IE 7+8 Anyone got an idea?

  • How can I emulate the ASP.NET Ajax UpdatePanel when using ASP.NET MVC?

    - by Gary McGill
    In "traditional" ASP.NET (Web Forms), the UpdatePanel control lets you do a partial refresh of a part of a page. You don't need to write much code to hook this up. What's the equivalent in ASP.NET MVC? I'm guessing I'd need to use a partial view for the bit that I want to update, then on the client side retrieve that HTML and pump it into the innerHtml of the correct DIV? A tutorial/example would be helpful...

  • prettyphoto and nivoslider

    - by Gabriel Ciprian Magda
    I have added the nivoslider and prettyphoto lightbox to a page. What I am trying to do: when you click one of the nivoslider images, prettyphoto should load a video. Everything works ok, except that whenever the nivo slider is sliding the images, the video in prettyphoto lightbox is reloading. How can I prevent the video from reloading once the sliding images are changing? I am not a javascript nija but I am guessing it can be done with changepicturecallback: function(){} from prettyphoto...

  • Looping through Markers with Google Maps API v3 Problem

    - by Oscar Godson
    I'm not sure why this isn't working. I don't have any errors, but what happens is, no matter what marker I click on, it clicks the 3rd one (which is the last one out of 4 markers. Array starts at 0, obviously) and shows the number "3", which is correct for THAT one, but I'm not clicking that one. Here is most of my code, just not the array of [place-name, coordinates] (var locations, which you will see): function initialize() { var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 15, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); var infowindow = new Array(); var marker = new Array(); for(x in locations){ console.log(x); infowindow[x] = new google.maps.InfoWindow({content: x}); marker[x] = new google.maps.Marker({title:locations[x][0],map:map,position:locations[x][1]}); google.maps.event.addListener(marker[x], 'click', function() {infowindow[x].open(map,marker[x]);}); } } initialize() The console.log output is (its correct, and what i expect): 0 1 2 3 So, any ideas?

  • Phonegap jqm mixing local and server html files

    - by DavidVdd
    I would like to add some online pages to an application keep them up to date without releasing a new store version. For this I taught I could use jqm ajax navigation to load the external page. (I'm aware that might not be allowed for all platforms.) I have set: $.mobile.allowCrossDomainPages = true; $.mobile.pushStateEnabled = false; This seems to work but the problem is that all my href's and $.mobile.ChangePages would have to be changed to <a href='http://mydomain.com/mypage.html'>link</a> $.mobile.changePage('http://mydomain.com/mypage.html'); in stead of <a href='mypage.html'>link</a> $.mobile.changePage('http://mydomain.com/mypage.html'); I was thinking about overriding the changepage method(found this somewhere) to add a domain when the user is online, but the problem is that this method get's called more then once. var originalChangePage = $.mobile.changePage; $.mobile.changePage = function(to, options) { var o = JSON.stringify(o); try { to = to.replace('file:///android_asset/www/', 'http://mydomain.com/'); } catch (err) { //to isn't always filled in. } originalChangePage(to, options); }; Is there a better way to load html pages locally and online using jqm ajax navigation? Extra info: Phonegap/Cordova version 3.5.0 jqm 1.3.2

  • Send asapMail without reloading page using ajax

    - by Darren Cook
    Hi, I have a form that posts data to an aspMail file for delivery (works fine in current format), but would like to have the form data sent without having to re-direct to another page. Looks like Ajax is the way to proceed but I'm having a problem getting the setup to work. Here's how I've changed the html: Added: $('#myForm').submit(function() { $.ajax({ data: $(this).serialize(), type: $(this).attr('post'), url: $(this).attr('aspSend.asp'), success: function(response) { $('#created').html(response) } }); }); Changed the form tag from: <form name="myForm" action"aspSend.asp"> to: <form name="myForm"> but now the emails don't arrive!! Any suggestions?
