• 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!

• JQuery live function doesn't work

  - by Sayem Ahmed

  I have some text boxes, all of which have the same class "addExamNumberBoxStyle". Now I want to bind a "blur" handler to each one of these. When I use direct "blur" event like below - $('.addExamNumberBoxStyle').blur(function() { alert("Hello World"); }); it works perfectly. But when I use "live" function like below - $('.addExamNumberBoxStyle').live('blur', function() { alert("Hello World"); }); it does not work. Why?

• Populate table with JQuery

  - by Talkar

  I need to populate some data into a table. The data i have is something i get in response from my ASP.NET MVC site, when i make a json post call there. Yet i can't seem to find a way to actually display the data i get back in response. Here is my code so far. Any help would be much appreciated: $(document).ready(function () { var uName = '<%= Session["UserName"].ToString()%>'; var pWord = '<%= Session["Password"].ToString()%>'; var data = { UserName:uName,Password:pWord}; $.ajax( { type: 'POST', url: "http://someurl.goes.here/", crossDomain: true, data: data, dataType: 'jsonp', success: function(myData) { $.each(myData, function (index, element) { $("#ClassTable").append('<tr><td> ' + element[0] + ' </td> <td> ' + element[1] + '</td></tr>'); }) } }); }); myData looks like this: [Object { IsActive = True, ObjectId=1, ObjectString="someString", etc... etc... } ]

• 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!

• Is there a free (LGPL compatible) Grid plugin for jQuery that has similiar capabilities to the Ext-J

  - by Ehrann Mehdan

  One of the most appealing features of Ext-JS is the Grid control in my opinion. I was searching for something free that does something close and have set my hopes on jQuery. I haven't found a jQuery (or other LGPL compatible) Table / Grid plugin that allows to: Reorder columns by dragging Resize columns by dragging Add or Remove columns on the fly Have a default good looking UI (subjective, but Ext-JS look I think is a concensus) In addition to the rest most grid controls have (Sort, Paging etc) Is there a free (LGPL) jQuery plugin that does the above?

• Reset variable in javascrtp (jQuery)

  - by superUntitled

  I am trying to reset a variable (that updates the src value for an image) when an area of an image map is clicked, so that the hover function calls a different image when the user hovers over another area in the image map. I have a variable called "state" that I set right off the bat. This is the variable that I want to reset when an area is clicked. var state = "path/to/images/feed1.png"; I have a couple of functions involving hover() and click(). $("#Map area").click( function () { var button = $(this).attr("id"); // here is where i want to reset the 'state' variable var state = "path/to/images/" + button + ".png"; alert("you clicked "+button+" hello"); return false; } ); $("#Map area").hover( function () { var button = $(this).attr("id"); over("path/to/images/" + button + ".png"); }, function () { off(); }); And some functions that these functions call: function over(image) { $("#feednavImg").attr("src", image); } function off() { $("#feednavImg").attr("src", state); }

• jQuery .queue() not working as expected

  - by Andrew

  The page in question is right here: http://s289116086.onlinehome.us/lawjournaltv/index.php I'm 90% of the way there, I'm just assuming there's an error with my syntax. Focus on the blue callout area with "Workers' Compensation" as the title: Basically, I've created a little slideshow there with the controls at the top and when you click on any of them both the callout and the background are to slide. As you can see it's working now, but the problem is that I want the new background to slide in over the old one. I've tried several things including the queue() method, delay(), and adding everything else to the animate() callback with no success (right now the background goes black and then the new image slides in). You guys have never let me down before, so I'm hoping this is an easy fix. Thanks in advance!

• .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

• JQuery function not working as expected

  - by Mike

  I've written a little function to position a logo midway between the left hand side of the browser window and the (centered) navigation menu. The menu items are populated from a database, with the first item given the id item0. function positionLogo(){ var $menuleft=0; var $element=document.getElementById('item0'); if ($element.offsetParent) { do { $menuleft+=$element.offsetLeft; } while ($element=$element.offsetParent); } var $logoleft=($menuleft/2)-130; // As logo is 260px wide if ($logoleft<0) { $logoleft=0; } $('#logo').css('left',$logoleft); } $(document).ready(function(){ positionLogo(); }); $(window).resize(function(){ positionLogo(); }); This works fine when the window is resized, but when it first runs when the page is loaded, the position it sets is about 20px too far right (ie $logoleft is 20 more than it should be). As soon as the page is resized it jumps into the correct position. Haven't got it live anywhere at the moment but does anyone have any ideas? Thanks!

• 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 performance of binding multiple click events.

  - by DA

  I have a situation where I need to bind a click event to an object multiple times. For instance: for(i=0;i<=100;i++){ $myObject.click(function(){ window.location = "myurl"+i+".html"; }) ...do other stuff... } Via that markup, does $myObject end up with 100 click events attached to it? Should I be unbinding the click event first each time? for(i=0;i<=100;i++){ $myObject.unbind('click').click(function(){ window.location = "myurl"+i+".html"; }) ...do other stuff... }

• jQuery without domready

  - by Happy

  Searching for a way to add this code, after the <head> (or some <link stylesheet>) and before <body> is generated (created). $('body').append('<style type="text/css">\ // some // multiline // styles </style>'); There is no <body> without domready(), so its seems better to use head instead or something else. Append also can be replaced. Anybody knows how to do that? Thanks.

• $.(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 - Make my script work?

  - by JasonS

  Hi, I have written a script. It does work! It's just a bit rubbish. Could someone tell me where I am going wrong. Basically, I have a 5 star rating box. When the mouse hovers over the various parts of the box I need the stars to change. Currently the stars only change when you move your mouse over and out of the element. I need the stars to change while the mouses within the element. I think the problem is with the event but I have tried a couple and it seems to make no difference. $(".rating").mouseover(function(e) { // Get Element Position var position = $(this).position(); var left = position.left; // Get mouse position var mouseLeft = e.pageX; // Get Actual var actLeft = mouseLeft - left; $(".info").html(actLeft); if (actLeft < 20) { $(this).attr('style', 'background-position:0;'); } else if (actLeft < 40) { $(this).attr('style', 'background-position:0 -20px;'); } else if (actLeft < 60) { $(this).attr('style', 'background-position:0 -40px;'); } else if (actLeft < 80) { $(this).attr('style', 'background-position:0 -60px;'); } else { $(this).attr('style', 'background-position:0 -80px;'); } });

• jQuery click(): overriding previously-bound click events

  - by JamesBrownIsDead

  When I use this code with an element whose id is "foobar": $("#foobar").click(function () { alert("first"); }); $("#foobar").click(function () { alert("second"); }); I get two alerts: "first" and "second" second. How do I specify a click event that also clears out any previous click events attached to the element? I want the last $("#foobar").click(...) to erase any previously bound events.

• Multiplying field value with retreived value jQuery

  - by Efe

  I pull product price from another page. Then I multiply it with quantity entered in the quantity input field. The problem is, if I forget to enter quantity value before I pull product price data or if I change the quantity field later, the final total price is not updated. I hope I clearly explained it. javascript: $('#AddProduct').click(function() { var i = 0; var adding = $(+(i++)+'<div class="row'+(i)+'"><div class="column width50"><input type="text" id="PRODUCTNAME" name="PRODUCTNAME'+(i)+'" value="" class="width98" /><input type="hidden" class="PRODUCTID" name="PRODUCTID" /><input type="hidden" class="UNITPRICE" name="UNITPRICE'+(i)+'" /><small>Search Products</small></div><div class="column width20"><input type="text" class="UNITQUANTITY" name="UNITQUANTITY'+(i)+'" value="" class="width98" /><small>Quantity</small></div><div class="column width30"><span class="prices">Unit Price:<span class="UNITPRICE"></span><br />Total Price:<span class="TOTALPRICE"></span><br /><a href="#" id="RemoveProduct(".row'+(i)+'");">Remove</a></span></div>'); $('#OrderProducts').append(adding); adding.find("#PRODUCTNAME").autocomplete("orders.cs.asp?Process=ListProducts", { selectFirst: false }).result(function(event, data, formatted) { if (data) { adding.find(".UNITPRICE").html(data[1]); adding.find(".PRODUCTID").val(data[2]); adding.find(".TOTALPRICE").html(data[1] * $('.UNITQUANTITY').val()); } }); return false; }); $('#RemoveProduct').click(function() { $().remove(); return false; }); my html: <fieldset> <h2>Order Items</h2> <div id="OrderProducts"> <a href="#" id="AddProduct"><img src="icons/add.png" alt="Add" /></a> </div> </fieldset> edit Now I totaly messed it up. Removing a row is not working anymore as well... Test link: http://refinethetaste.com/html/cp/?Section=orders&Process=AddOrder#

• Example of tree.drop_mode with jQuery sortable anywhere

  - by fred

  Hello Everyone, I have a working tree of galleries next to a sortable list of image thumbnails. I've been vainly trying to set up the galleries tree so that users can add images to the galleries by dropping the sortable thumbnails on to the galleries tree. I've been told this requires drop_mode. All efforts to get it to work have failed and I can't really make heads or tails of the drop_mode documentation. I've sought out some working examples via Google of just such an application but have failed. Can anyone point me to a working example of either a draggable or sortable list that successfully drops on to a tree and passes along some parameters between the two? Thanks!
