  • Filtering data in an array.

    - by user276424
    Hi all, I have an array that has 30 date objects. The date objects are indexed in the array from the minimum date value to the maximum date value. What I would like to do is retrieve only 7 dates from the array. Out of the 7, the first one should be the minDate and the last should be the maxDate, with 5 dates in the middle. The 7 numbers should increment evenly from the minDate to the maxDate. How would I accomplish this? Hope I was clear. Thanks, Tonih

  • How can I tell when changes to jquery html() have finished ?

    - by mike_t2e
    I'm using jQuery to change the HTML of a tag, and the new HTML can be a very long string. $("#divToChange").html(newHTML); I then want to select elements created in the new HTML, but if I put the code immediately following the above line it seems to create a race condition with a long string where the changes that html() is making may not necessarily be finished rendering. In that case, trying to select the new elements won't always work. What I want to know is, is there an event fired or some other way of being notified when changes to html() have finished rendering ? I came across the jQuery watch plugin, which works alright as workaround but it's not ideal. Is there a better way ?

  • A smoother alternative to jQuery show() and hide()

    - by David B
    I have a page setup with a hidden column using the jQuery show() and hide() functions to slide the column in and out. However it's kind of "clunky" and does not look very smooth when showing/hiding; in contrast I also have a section of the page using jquery UI accordion. When switching between these sections the transition looks very nice and smooth... Is there a better function than show()/hide() which looks as nice as the accordion does? (maybe the "easing" parameter can be used in the show/hide functions, but i'm not sure how to use this properly?)

  • How to implement a Client-side Ajax Login on Asp.Net MVC (A link to the solution for Asp.Net Webform

    - by Matt
    Hi, I'm trying to implement a client-side ajax login on Asp.Net MVC. I used to have this set up just fine on WebForms, but now that I've moved to MVC it's giving me some troubles. If you'd like a tutorial on Client-side Ajax Login for Asp.Net Webforms, it can be found here -- Easy, A++ Now... for some reason it's not working for Asp.Net MVC. I used the exact same tutorial as for the Webforms, except when it executes the ssa.login() (equivalently: Sys.Services.AuthenticationService.login()) it's not doing anything. I have alerts in both the onLoginComplete() function and the onError() function. As well I have an alert before the ssa.login gets called and right after... function loginHandler() { var username = $("#login_UserName").val(); var password = $("#login_Password").val(); var isPersistent = $("#login_RememberMe").attr("checked"); var customInfo = null; var redirectUrl = null; // Log them in. alert("try login"); ssa.login(username, password, isPersistent, customInfo, redirectUrl, onLoginComplete, onError); alert("made it here"); } The first alert fires but the second one doesn't which means the function is failing. Here's the function I pulled from Asp.Net Ajax to show you: function(c, b, a, h, f, d, e, g) { this._invoke(this._get_path(), "Login", false, { userName: c, password: b, createPersistentCookie: a }, Function.createDelegate(this, this._onLoginComplete), Function.createDelegate(this, this._onLoginFailed), [c, b, a, h, f, d, e, g]); } Anyone have any idea of why it's failing?

  • customise jQuery totemticker plugin

    - by Don
    I'm using the totemticker jQuery plugin, but need to be able to stop it programatically. It doesn't seem to provide this feature, so I had a look at the source code to see if I could add it myself. It seems that all I need to do is figure out how to call base.stop_interval() However, I can't seem to make the object that is stored in base accessible to callers. I've made a couple of unsuccesful atttempts, but hopefully someone who knows a bit more about how jQuery plugins work can point me in the right direction.

  • JSP: Refresh ComboBox options

    - by framara
    Hi, There's a class 'Car' with brand and model as properties. I have a list of items of this class List<Car> myCars. I need to represent in a JSP website 2 ComboBox, one for brand and another for model, that when you select the brand, in the model list only appear the ones from that brand. I don't know how to do this in a dynamic way. Any suggestion where to start? Thanks Update Ok, what I do now is send in the request a list with all the brand names, and a list of the items. The JSP code is like: <select name="manufacturer" id="id_manufacturer" onchange="return getManufacturer();"> <option value=""></option> <c:forEach items="${manufacturers}" var="man"> <option value="${man}" >${man}</option> </c:forEach> </select> <select name="model" id="id_model"> <c:forEach items="${mycars}" var="car"> <c:if test="${car.manufacturer eq man_selected}"> <option value="${car.id}">${car.model}</option> </c:if> </c:forEach> </select> <script> function getManufacturer() { man_selected = document.getElementById('id_manufacturer').value; } </script> How do I do to refresh the 'model' select options according to the selected 'man_selected' ?

  • Problems crossing the boundary between protected greasemonkey execution space and the unsafeWindow l

    - by Chilly
    Hi guys. Here is my problem: I've registered some callbacks into a Yahoo event driven webpage (betfair.com market views) and am trapping the betsPlaced events with a handler. So far so simple. Next stage is to get the event back into greasemonkey land, and while I know that from greasemoney space you can call unsafeWindow.stuff, there is no reverse operation (by design). So if I want to send the contents of the event over, say, a cometd queue, my carefully set up jquery, greasemonkey, YUI2, betfair environment fails by telling me that unsafeWindow processes cant call GM_ajax stuff. This is obviously safe and sane, but it basically stops me doing what I want to do. Has anyone tried doing this (ignore the cometd stuff, just general ajax calls) and succeeded? I've had a look at pages like this: http://wiki.greasespot.net/0.7.20080121.0%2B_compatibility but it doesnt appear to work for all the calls.

  • jQuery removing elements from DOM put still reporting as present

    - by RyanP13
    Hi, I have an address finder system whereby a user enters a postcode, if postcode is validated then an address list is returned and displayed, they then select an address line, the list dissappears and then the address line is split further into some form inputs. The issue i am facing is when they have been through the above process then cleared the postcode form field, hit the find address button and the address list re-appears. Event though the list and parent tr have been removed from the DOM it is still reporting it is present as length 1? My code is as follows: jQuery // when postcode validated display box var $addressList = $("div#selectAddress > ul").length; // if address list present show the address list if ($addressList != 0) { $("div#selectAddress").closest("tr").removeClass("hide"); } // address list hidden by default // if coming back to modify details then display address inputs var $customerAddress = $("form#detailsForm input[name*='customerAddress']"); var $addressInputs = $.cookies.get('cpqbAddressInputs'); if ($addressInputs) { if ($addressInputs == 'visible') { $($customerAddress).closest("tr").removeClass("hide"); } } else { $($customerAddress).closest("tr").addClass("hide"); } // Need to change form action URL to call post code web service $("input.findAddress").live('click', function(){ var $postCode = encodeURI($("input#customerPostcode").val()); if ($postCode != "") { var $formAction = "customerAction.do?searchAddress=searchAddress&custpc=" + $postCode; $("form#detailsForm").attr("action", $formAction); } else { alert($addressList);} }); // darker highlight when li is clicked // split address string into corresponding inputs $("div#selectAddress ul li").live('click', function(){ $(this).removeClass("addressHover"); //$("li.addressClick").removeClass("addressClick"); $(this).addClass("addressClick"); var $splitAddress = $(this).text().split(","); $($customerAddress).each(function(){ var $inputCount = $(this).index("form#detailsForm input[name*='customerAddress']"); $(this).val($splitAddress[$inputCount]); }); $($customerAddress).closest("tr").removeClass("hide"); $.cookies.set('cpqbAddressInputs', 'visible'); $(this).closest("tr").fadeOut(250, function() { $(this).remove(); }); });

  • Flexslider position of previous and next slides

    - by TJ15
    I am using the basic flexslider, I wantto display some of the previous and next , so if slide 2 is showing you will see part of slide 1 to the left and part of slide 3 to the right. <!DOCTYPE html> <head> <link rel="stylesheet" href="flexslider.css" type="text/css"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> <style> .container {overflow: hidden; width: 100%} .flexslider {max-width: 500px; width: 500px; margin: 0 auto} .content {background: #f2f2f2; max-width: 500px; display: block; margin: 0 auto} .flex-viewport {overflow: visible !important} </style> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <div class="container"> <div class="flexslider"> <ul class="slides"> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> </ul> </div> </div> <script src="jquery.flexslider.js"></script> <script> jQuery(document).ready(function($) { // You can use the locally-scoped $ in here as an alias to jQuery. $(window).load(function() { $('.flexslider').flexslider(); }); }); </script> </body> </html> I have reduced the image to 70% and positioned it in the middle of the page. I want to have the next and previous slides visible on either side of the main pic but no idea where to make the appropriate changes (I assume in the js file). I thought this was a margin issue but setting this to 0 in styles makes no difference. Has anyone done this and can provide some advice?
