  • sorting nested list, allow only li to be sorted witin the same ul

    - by Y.G.J
    what i want to achive is: sorting the main ul is working but not all the time - i will try to fix that my own but if there is a problem with the code here and not the one in proccess-sortable - tell me. moving li in the main ul is ok but the sub or the sub of the sub is having problem - i can drag something from one sub to it's sub or the other way too - i don't want that to happend. i want to be able to drag li and by selecting that one that only this ul group will send to proccess-sortable to be updated - how can i catch the specific ul of li i am draging? $(document).ready(function() { $("#test-list").sortable({ items: "> li", handle : '.handle', axis: 'y', opacity: 0.6, update : function () { var order = $('#test-list').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); $("#test-sub").sortable({ containment: "ul", items: "li", handle : '.handle2', axis: 'y', opacity: 0.6, update : function () { var order = $('ul').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); }); this is the html part <ul id="test-list"> <li id="listItem_10">first<img align="middle" src="Themes/arrow.png" class="handle" /></li> <li id="listItem_8">second<img align="middle" src="Themes/arrow.png" class="handle" /> <ul id="test-sub"> <li id="listItem_4><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <li id="listItem_3"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <ul id="test-sub"> <li id="listItem_9"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> </ul> </li> </ul> </li> </ul>

  • Expand and collapse a div

    - by user494118
    I have a list of itens and they are holding images, each image is 800w x 600 H. The original div height is 800 W x 300 H, I figured out how to expand the div when it is clicked, but i want to know how to collapse it when you click it while it is already expanded. right now it just expands the div even farther $('.expand').bind('click', function() { var currHeight = $(this).css('height').replace(/px/,''); currHeight = currHeight * 1; var newHeight = currHeight + 500; $(this).animate({ height: newHeight },1000); }); any idea on how to create an if else statement that would say, IF the div is already expanded then collapse on click, or if the div is not expanded, expand to # of px.

  • Swapping content in a seperate div on hover

    - by Fuego DeBassi
    I feel like this should work: $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); Basically I am hiding all the .children of "#viewport on load, then when a seperate element is hovered, in this case .module .one I want to change something on the corresponding viewport ID #viewport #one. Basic idea is a variable content window, where when a thumbnail or whatever I put in the modules swaps the content shown in the viewport. Something I am doing wrong? Here is my full code: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $("#viewport").children().hide(); $(".module").hover(function() { $(this).find(".caption").slideDown().end().siblings('.module').addClass('under'); },function() { $(this).find(".caption").slideUp().end().siblings('.module').removeClass('under'); }); $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); }); </script> The bigger hover function in the middle is for some fancy rollover effects that the modules will perform themselves, but for these purposes I just want to figure out why I can't add a Class to a separate element when another is hovered. Would love some help/advice!

  • How to suppress jqgrid from initially loading data?

    - by Steve Johnston
    I have a page that has a couple of jqGrids on it, along with a few other fields. I want to make one AJAX call myself that pulls back a JSON object that has the data that should be used to fill the entire page. So, I would like to make the call myself, populate the "other fields" and then pull a couple of collections off of the main JSON object that was returned and populate each of the jqGrids with those collections "manually". I have this much working, but I can't get jqGrid to stop attempting to make an AJAX request itself. Shouldn't there be a way to tell jqGrid to NOT attempt an AJAX call when it is initialized? I found a similar question asked here: http://stackoverflow.com/questions/1850159/how-to-suppress-jqgrid-from-initially-loading-data But I don't have the option that solved it for the poster. It seems pretty logical to me that some people may want to use this plugin without having the table attempt to get its own data upon initialization. Am I missing an option somewhere in the documentation (wiki - options)? Thanks.

  • Use queried json data in a function

    - by SztupY
    I have a code similar to this: $.ajax({ success: function(data) { text = ''; for (var i = 0; i< data.length; i++) { text = text + '<a href="#" id="Data_'+ i +'">' + data[i].Name + "</a><br />"; } $("#SomeId").html(text); for (var i = 0; i< data.length; i++) { $("#Data_"+i).click(function() { alert(data[i]); RunFunction(data[i]); return false; }); } } }); This gets an array of some data in json format, then iterates through this array generating a link for each entry. Now I want to add a function for each link that will run a function that does something with this data. The problem is that the data seems to be unavailable after the ajax success function is called (although I thought that they behave like closures). What is the best way to use the queried json data later on? (I think setting it as a global variable would do the job, but I want to avoid that, mainly because this ajax request might be called multiple times) Thanks.

  • Need some help with onClick and an if/else issue...

    - by Adam
    I have a menu with seven items. If you click the first item, div one shows. If you click any other item (2 through 7) div two shows. That's what I'm looking to do. I'm new at all this but am pretty sure it's an if/else function, such that if I click on <a id="1">, show the first div, else show the second div. I suppose I can do a hide/show to get back to the first div. I'm going to keep poking around, but if I can't find it, any help is surely appreciated.

  • fullcalendar events from REST-ful php server.

    - by biagidp
    I've written a very simple RESTful php server (my first experiment with REST, so feel free to make suggestions) to respond to the fullcalendar events callback. It produces exactly the same string output as the json-events.php file in the fullcalendar json example, but for some reason fullcalendar will not accept my server's output. I've tried messing with the headers because they're different from the ones produced by json-events.php, but I'm not really sure what's awry there, if anything. The code for the server is below: <?php class Listener{ function __construct() { $this->getResource(); $this->buildResponse(); } function getResource(){ $parts = explode('/', $_SERVER["REQUEST_URI"]); $script_name = end(explode('/', $_SERVER["SCRIPT_NAME"])); $this->resource = $parts[array_search($script_name, $parts) + 1]; $this->resource_id = $parts[array_search($script_name, $parts) + 2]; } function buildResponse(){ $method = strtolower($_SERVER["REQUEST_METHOD"]); $this->response_string = $method . ucwords($this->resource); } function getResponse(){ return $this->response_string; } } $listener = new Listener(); $thing = $listener->getResponse(); #$thing(); function getEvents(){ $year = date('Y'); $month = date('m'); echo json_encode(array( array( 'id' => 111, 'title' => "Event1", 'start' => "$year-$month-10", 'url' => "http://yahoo.com/" ), array( 'id' => 222, 'title' => "Event2", 'start' => "$year-$month-20", 'end' => "$year-$month-22", 'url' => "http://yahoo.com/" ) )); } ?> Any input, help or suggestions would be greatly appreciated!

  • Multiple ajax request and progress bar

    - by hunt
    Hi, In a following piece of code i am create a progress bar and showing its progress as the ajax request get processed. i am faking the progress shown here just by adding 5 in to cnt counter variable after that i made a check when counter reach to 90. at this point if the request is not executed successfully then i will pause/disable the progress bar and whenever response come i will complete the whole progress bar with 100. now the problem is i want to add multiple progress bar as i am firing multiple ajax request. so following is the code to implement only for one request and one progress bar but i want it for more than one. as global variables are used over here for checking response and timer id so i don't know how well i can handle it for multiple request var cnt=0; var res=null; function getProgress(data){ res=data; } var i =0; $('#start').click(function(){ i = setInterval(function() { if(res!=null) { clearInterval(i); $("#pb1").progressbar( "option", "value", cnt=cnt+100 ); } var value = $("#pb1").progressbar("option", "value"); if(value >=90 && res==null){ $("#pb1").progressbar("option", "disable"); } else{ $("#pb1").progressbar( "option", "value", cnt=cnt+5 ); } },2500); $.ajax({ url: 'http://localhost/beta/demo.php', success: getProgress }); }); $("#pb1").progressbar({ value: 0 , change: function(event, ui) { if(res!=null) clearInterval(i); } });

  • Javascript regex returning true.. then false.. then true.. etc

    - by betamax
    I have a strange problem with the validation I am writing on a form. It is a 'Check Username' button next to an input. The input default value is the username for example 'betamax'. When I press 'Check Username' it passes the regex and sends the username to the server. The server behaves as expected and returns '2' to tell the javascript that they are submitting their own username. Then, when I click the button again, the regex fails. Nothing is sent to the server obviously because the regex has failed. If I press the button again, the regex passes and then the username is sent to the server. I literally cannot figure out what would be making it do this! It makes no sense to me! This is my code: $j("#username-search").click(checkUserName); function checkUserName() { var userName = $j("#username").val(); var invalidUserMsg = 'Invalid username (a-zA-Z0-9 _ - and not - or _ at beginning or end of string)'; var filter = /^[^-_]([a-z0-9-_]{4,20})[^-_]$/gi; if (filter.test(userName)) { console.log("Pass") $j.post( "/account/profile/username_check/", { q: userName }, function(data){ if(data == 0) { $j("#username-search-results").html("Error searching for username. Try again?"); } else if(data == 5) { $j("#username-search-results").html(invalidUserMsg); } else if(data == 4) { $j("#username-search-results").html("Username too short or too long."); } else if(data == 2) { $j("#username-search-results").html("This is already your username."); } else if(data == 3) { $j("#username-search-results").html("This username is taken."); } else if(data == 1){ $j("#username-search-results").html("This username is available!"); } }); } else { console.log("fail") $j("#username-search-results").html(invalidUserMsg); } return false; } The HTML: <input name="username" id="username" value="{{ user.username }}" /> <input type="button" value="Is it taken?" id="username-search"> <span id="username-search-results"></span>

  • juqery image fading with tabs

    - by StealthRT
    Hey all, i am trying my best to figure out how to go about doing this: I have 2 tabs. When the page loads tab1 is selected automatically. This shows the tab as 1.0 transparency while tab2 stays at 0.7. Once the user clicks on tab2, tab1 goes to 0.7 transparency and tab2 goes to 1.0. However, i can not seem to get it to do that! Here is my code: function checkTab(theTab) { $('#tab1').fadeTo(250, 0.70); $('#tab2').fadeTo(250, 0.70); if ($("#tabActive").val() == theTab) { $(theTab).fadeTo(250, 1); } } $(document).ready(function() { $('#tab1').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab1')}); $('#tab2').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab2')}); $('#tab2').fadeTo(250, 0.70); $('#tabActive').val('tab1'); }); </script> <li class="stats"><img src="images/Stats.png" name="nav1" width="70" height="52" id="tab1" onclick="$('#tabActive').val('tab1');" /></li> <li class="cal"><img src="images/cal.png" name="nav1" width="70" height="52" id="tab2" onclick="$('#tabActive').val('tab2');" /></li> <input name="tabActive" id="tabActive" type="text" /> Any help would be great! :) David

  • Caching issue with javascript and asp.net

    - by Ed Woodcock
    Hi guys: I asked a question a while back on here regarding caching data for a calendar/scheduling web app, and got some good responses. However, I have now decided to change my approach and stat caching the data in javascript. I am directly caching the HTML for each day's column in the calendar grid inside the $('body').data() object, which gives very fast page load times (almost unnoticable). However, problems start to arise when the user requests data that is not yet in the cache. This data is created by the server using an ajax call, so it's asynchronous, and takes about 0.2s per week's data. My current approach is simply to block for 0.5s when the user requests information from the server, and cache 4 weeks either side in the inital page load (and 1 extra week per page change request), however I doubt this is the optimal method. Does anyone have a suggestion as to how to improve the situation? To summarise: Each week takes 0.2s to retrieve from the server, asynchronously. Performance must be as close to real-time as possible. (however the data is not needed to be fully real-time: most appointments are added by the user and so we can re-cache after this) Currently 4 weeks are cached on either side of the inial week loaded: this is not enough. to cache 1 year takes ~ 21s, this is too slow for an initial load.

  • Catching the Facebook Login Event to change the HTML of the parent page

    - by Arkid
    I am trying to create Facebook based login using Javascript. Once a person clicks a button he should get a div replaced by another div, if he is logged in to Facebook. However, if he is not logged in to Facebook he is asked his Facebook credentials and he logs in. However, we need the user to click the button once more for the div replacement to happen in this case. I want to know if there is a way in which I can catch the Facebook login event and change the div? Is polling a way or there is some other way out. I want to use only Javascript.
