  • Proper way to format date from database using javascript/jquery

    - by Darcy
    Hi all, I am calling my database which contains a datetime datatype. The date looks like this: 2005-05-23 16:06:00.000 I would like to display this in a table when a user selects a certain item from a list. I call my controller action and return Json of all the times and put them in a table. The problem is the date is completely wrong. What is displayed is this: /Date(1255470180000)/ The date that is returned isn't even parsable (which I don't want to do anyway) so I can't even get the data if I wanted to. Any ideas?

  • jquery: mouseleave event seems to fire when it's not supposed to

    - by Jeremy
    Given the following html table and script shown below I am having a problem where the mouse leave event appears to fire right after the mouse enter, even if I don't move the mouse out of the row. <script type="text/javascript" language="javascript"> function highlightRows(iMainID) { $('tr[mainid=' + iMainID+ ']').each(function() { if ($(this).attr('old') == undefined) { $(this).attr('old', $(this).css('backgroundColor')); } $(this).animate({ backgroundColor: "#FFFFCC" }, 500); $(this).mouseout(function() { if ($(this).attr('old') != undefined) { $(this).animate({ backgroundColor: $(this).attr('old') }, 500); } }); }); } </script> <table> <tr> <td mainid="1" onmouseover='highlightRows(1)'><div>text</div></td> <td mainid="1" onmouseover='highlightRows(1)'><div>text</div></td> <td mainid="2" onmouseover='highlightRows(2)'><div>text</div></td> </tr> <table>

  • jQuery test if element1 is child of element2

    - by Jake
    Does anyone know a good way to test if one element, stored in a var, is the child of another, also stored in a var? I don't need element1.isChildOf('selector'), that's easy. I need element1.isChildOf(element2) element2.find(element1).size() > 0 Does not seem to work. I don't want to have to write a plugin the uses .each to test each child if I can avoid it.

  • vertical navigation that shows hidden submenu on click using JQuery

    - by user346602
    Hi, I am trying to make a menu that works like the one on this flash site: http://elevensix.de/ When I click "portfolio", only then to the subnavigation links reveal themselves. Right now I have only managed to get a typical vertical "reveal subnavigation on hover menu" working. What is required is that once the appropriate menu item it cicked, its submenu shows. This submenu remains revealed as the submenu items are hovered over then selected. When the submenu item is selected, the content shows, and both the menu and submenu remain visible (the selected menu and submenu item are given a distinct colour to show the navigation path). Whew. Here is my html: <div id="nav"> <ul> <li><a href="#">about</a></li> <li><a href="#">testimonials</a> <ul> <li><a href="#">testimonial1</a></li> <li><a href="#">testimonial2</a></li> <li><a href="#">testimonial3</a></li> <li><a href="#">testimonial4</a></li> </ul> </li> <li><a href="#">Services</a> <ul> <li><a href="#">services1</a></li> <li><a href="#">services2</a></li> <li><a href="#">services3</a></li> <li><a href="#">services4</a></li> </ul> </li> <li><a href="#">Gallery</a></li> <li><a href="#">Contact</a></li> </ul> </div><!--end #nav--> and here is my css: #nav { width:160px; position: relative; top: 250px; left: 20px; } #nav ul { margin:0px; padding:0px; } #nav ul li { line-height:24px; list-style:none; } #nav a { text-decoration: none; color: #9d9fa2; } #nav ul li a:hover { position:relative; color: #00aeef; } #nav ul ul { display:none; position:absolute; left:160px; top:4px; } #nav ul li:hover ul { display:block; color: #00aeef; } #nav ul ul li { width:160px; float:left; display:inline; line-height:16px; } .selected { color: #00aeef !important; } Should I be giving the submenus a class so that I can hide then show them? And where would the class be applied? To the ul? could I use the same class for both submenus? Am I wrong in how I am applying the display:none values for this purpose? Many thanks to all the clever people on here.

  • Real-time data on webpage with Django and jQuery

    - by Steven Hepting
    I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to a Django view at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (I've already done this part).

  • jQuery ajax post dynamic url insertion

    - by Kirill
    $.ajax({ type: "POST", url: "OMFG.php", data: info, success: function(){ }}); is what I'm using atm as a test and it works fine. I need to get the url from the link I'm clicking, so I do: var url = $(this).attr("href"); which works fine if I alert it out(the link includes http://samedomain.com/etc.php), but the ajax function doesn't post if I insert it into the ajax code: $.ajax({ type: "POST", url: url, data: info, success: function(){ }}); Please help, as I'm screwed without this working.

  • jQuery; combine user click and :checked

    - by user275074
    I have two blocks of code which basically check for 1) a click event on a radio button e.g. $("input[id='frmSkill']").click(function(){ //do something }); And 2) a block of code to check if a radio button is :checked, if so, then perform some actions e.g. if($("input[id='frmSkill']:checked").val()){ //do something }); What I'd like to do is combine the two in order to reduce the code as the actions performed under each are the same.

  • how to organize javascripts using rails and jquery

    - by VP
    Hi, i'm working in a big and rich rails web application using tons of javascript. I would like to know if anybody has a tip to organize the javascripts. Today i'm generating a new file named controller.js and adding it to my views using content_for. The problem is, some files are becoming big and sometimes, i need a function from one controller in another, so then in the end, i add a products.js to a details controller just to keep DRY. Is that solution good? Any other tip? I think the same pattern can be applied as well to css files?

  • Some jQuery-powered features not working in Chrome

    - by Enchantner
    I'm using a jCarouselLite plugin for creating two image galleries on the main page of my Django-powered site. The code of elements with navigation arrows is generating dynamically like this: $(document).ready(function () { $('[jq\\:corner]').each(function(index, item) { item = $(item); item.corner(item.attr('jq:corner')) }) $('[jq\\:menu]').each(function (index, item) { item = $(item); item.menu(item.attr('jq:menu')) }) $('[jq\\:carousel]').each(function(index, item) { item = $(item); var args = item.attr('jq:carousel').split(/\s+/) lister = item.parent().attr('class') + '_lister' item.parent().append('<div id="'+ lister +'"></div>'); $('#' + lister).append("<a class='nav left' href='#'></a><a class='nav right' href='#'></a>"); toparrow = $(item).position().top + $(item).height() - 50; widtharrow = $(item).width(); $('#' + lister).css({ 'display': 'inline-block', 'z-index': 10, 'position': 'absolute', 'margin-left': '-22px', 'top': toparrow, 'width': widtharrow }) $('#' + lister + ' .nav.right').css({ 'margin-left': $('#' + lister).width() + 22 }) item.jCarouselLite({ btnNext: '#' + lister + ' .nav.right', btnPrev: '#' + lister + ' .nav.left', visible: parseInt(args[0]) }) }) The problem is that if page is loaded through an url, typed in the adress bar, some functions doesn't work and the second gallery appears with the wrong parameters, but if I came to this page via clicking link - everything works perfectly. It happends only in Google Chrome (Ubuntu, stable 5.0.360.0), but not in Firefox or Opera. What could be the reason?

  • .delegate equivalent of an existing .live method in jQuery 1.4.2

    - by kim3er
    I have an event handler bound to the hover event using the .live method, which is below: $(".nav li").hover(function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); It is important to note, that I require both functions within the handler to ensure synchronisation. Is it possible to rewrite the function using .delegate, as the following does not work? $(".nav").delegate("li", "hover", function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); Rich

  • CakePHP and jQuery - Unobtrusive actions

    - by fortysixandtwo
    I'm trying to make an unobtrusive action for deleting bookmarks in CakePHP. Allthough it's working just fine, I suspect there must be a better way to do this. Could someone please point me in the right direction? function delete($id = null) { $ok = $this->Bookmark->delete($id); if($this->RequestHandler->isAjax()) { $this->autoRender = false; $this->autoLayout = false; $response = array('status' => 0, 'message' => 'Could not delete bookmark'); if($ok) { $response = array('status' => 1, 'message' => 'Bookmark deleted'); } $this->header('Content-Type: application/json'); echo json_encode($response); exit(); } // Request isn't AJAX, redirect. $this->redirect(array('action' => 'index')); }

  • Parent CSS (jQuery)

    - by Glister
    There is <dl> with padding-top <dl style="padding-top: 150px;"> <dt>text</dt> <dd><img width="150" height="150" src="..." /></dd> <dt>text 2</dt> <dd><img width="150" height="250" src="..." /></dd> <dt>text 3</dt> <dd><img width="150" height="350" src="..." /></dd> </dl> The difference between images - height. Trying to write a script, which will change a height of the <dl>, when <dd> is clicked. Height should be taken from the height attribute of the dd img. Tryed this, but it doesn't work: $("#posters dd").click(function(){ var parent_padding = $(this).find("img").attr("height"); $(this).parent().css({"padding-top":parent_padding}); }); Thanks.

  • jquery-ui .draggable is not a function error

    - by niczoom
    I am getting the following error (using Firefox 3.5.9): $("#dragMe_" + myCount).draggable is not a function $("#dragMe_"+myCount).draggable({ containment: 'parent', axis: 'y' }); Line 231 http://www.liamharding.com/pgi/pgi.php Link to page in question : http://www.liamharding.com/pgi/pgi.php For example, click the 2 checkbox's 'R25 + R50 Random Walk' then click Show/Refresh Graphs. Two graphs should be displayed, both with draggable thin horizontal red lines. Re-open the options panel and de-select R50 Random Walk, now click Show/Refresh Graphs again, 1 graph is removed and the other updated; now re-select R50 Random Walk and click Show/Refresh, you will find the still checked R25 graph gets updated ok the above error occurs and i cant figure out why. Initially, when displaying the first 2 graphs it uses the same code and it works just fine.

  • $.(ajax) wrapper for Jquery - passing parameters to delegates

    - by gnomixa
    I use $.(ajax) function extensively in my app to call ASP.net web services. I would like to write a wrapper in order to centralize all the ajax calls. I found few simple solutions, but none address an issue of passing parameters to delegates, for example, if i have: $.ajax({ type: "POST", url: "http://localhost/TemplateWebService/TemplateWebService/Service.asmx/GetFoobar", data: jsonText, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { var results = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d; OnSuccess(results, someOtherParam1, someOtherParam2); }, error: function(xhr, status, error) { OnError(); } }); The wrapper to this call would have to have the way to pass someOtherParam1, someOtherParam2 to the OnSuccess delegate...Aside from packing the variables into a generic array, I can't think of other solutions. How did you guys address this issue?

  • jQuery Cycle plugin: One pager to control multiple slideshow on a page

    - by Michael
    Hi there, I have a cycle plugin set up on a page (images) with a pager to control the horizontal slide. My issue is that there is a transparent overlay that needs to sit over part of the images for some text relating to each image but would rather have that with a different transition effect for this so it doesn't slide in from the left. Am I able to set up to slideshows, each with 3 pieces of related content, that I can position correctly and have them controlled with the one pager? My script currently looks like this: $(function() { $('.s4').before('<div id="nav" class="nav">').cycle({ fx: 'fade', speed: 'slow', speedIn: 'slow', // speed of the 'in' transition speedOut: 'slow', timeout: 6000, pager: '#nav' }); }); I hope this makes sense, Thanks

  • jquery js how to avoid massive onmouseover onmouseout firing

    - by stephan
    i have a table with some columns. in each of them is a picture where i have a onmouseover onmouseout event on it, which show a message in a div and hide the msg. my problem is - after a user goes quick from left to right (and moving) over a lot o images. all mouseover/out events of the images where executed, which looks stupid... is it possible to rearrange the internal event stack to avoid this? so that he executes only the current (mostly the first event) - and than the last one, if it is not same type eg. if mouseover over first image is executed and mouse moving position stops over an image 3times next the first one. i can avoid all other events firing, because the mouse stopped over an image and the mouseover is like the one where i stopped with the mouse. how can i avoid this multiple event firing?!

  • jQuery Sortable + Droppable z-index problem

    - by unknowndomain
    I am having a probelm with the z-index of my sortable object not being above my droppable. If you visit http://clareshilland.unknowndomain.co.uk/. Press Ctrl + L to bring up the login screen. Enter the username clare and the password shilland. It will then load in the admin bar and if you click manage gallery. A pop down thumbnail view will appear with all the photos from that gallery. The issue is that when you drag the 'polaroids' from the grid to the delete area they are under the delete area. I tried putting the delete area inside the same div as the grid but it makes no difference, I just don't know what to do at this point so any help would be a massive help!

  • Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

    - by Acorn
    What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!

  • Jquery DateJs, is there validation for full date?

    - by Cesar Lopez
    Hi all, I just find out about the power of date js, And its great!!! As I am a newbie I was wondering if there is any kind of general validitation for different types of full dates. eg. var d1 = Date.parse('2000-10-18, 10:06 AM'); alert(d1.toString('HH:mm')); If date is ('200-10-18, 10:06 AM'), of course it doesn't like it. So my question is if there is any quick way to validate the full date, rather than having to validate one by one. Thanks.
