  • jQuery Accordian

    - by Fuego DeBassi
    Just wondering if anyone can provide some basic advice on an accordion I'm trying to simplify. Got a working version, but it seems way overly complex. Here is my new JS. $(document).ready(function() { $("#themes li ul").hide(); $("#themes li").hover(function() { $("ul").show(); }, function() { $("li ul").hide(); }); The markup looks like this: <ul> <li>Tier 1 <ul> <li>Tier 2</li> <li>Tier 2</li> </ul> </li> <li>Tier 1 <ul> <li>Tier 2</li> <li>Tier 2</li> </ul> </li> </ul> My script works alright. But it shows all of the child ul's when any parent li is hovered, and it hide's all the child ul's when unhovered. Just not sure how I can get it to A.) Only .show the li ul when that specific li is hovered. And B.) Hide the show'n li ul only when another one is hovered (not itself). Example + explanation would be especially helpful! Thanks!!

  • Problem with jquery #find on partial postback

    - by anonymous
    I have a third party component. It is a calendar control. I have a clientside event on it which fires javascript to show a popup menu. I do everything client side so I can use MVC. dd function MouseDown(oDayView, oEvent, element) { try { e = oEvent.event; var rightClick = (e.button == 2); if (rightClick) { var menu = $find("2_menuSharedCalPopUp"); menu.showAt(200, 200, e); } } catch (err) { alert("MouseDown() err: " + err.description); } } The javascript fires perfectly withe $find intially. I have another clientside method which updates the calendar via a partial postback. Once I have done this all subsequent MouseDowns( rightclicks) which use the $find statment error with 'null'. All similar problems people have out there seem to be around calling javascript after a postback - with solutions being re-registering an event using PageRequestManager or registering a clientside function on the server - et cetera. However, the event is firing, and the javascript working - it's the reference in the DOM that seems an issue. Any ideas?

  • too much recursion in javascript with jquery mouseover

    - by Stacia
    I am a JS novice. Using some code I found here to help me with mouseover scale/rotate images but now when I try to apply it to more than one object I'm getting errors saying "too much recursion". Before the function didn't take any arguments, it just was on s_1 and it worked fine. I am tempted to just write different code for each object but that isn't very good programming practice. var over = false; $(function(){ $("#s_1").hover(function(){ over = true; swing_left_anim("#s_1"); }, function(){ over = false; }); $("#np_1").hover(function(){ over = true; swing_left_anim("np_1"); }, function(){ over = false; }); }); function swing_left_anim(obj){ $(obj).animate({ rotate: '0deg' }, { duration: 500 }); if (over) { $(obj).animate({ rotate: '25deg' }, 500, swing_right_anim(obj)); } } function swing_right_anim(obj){ $(obj).animate({ rotate: '-25deg' }, 500, swing_left_anim(obj)); }

  • JQuery Tabs: How to get a list of the tab titles

    - by user340254
    As the title suggest, my question is what is the best way to get or build a list of the titles for the set of tabs. I was thinking I would have to build the list in a for loop, but there does not appear to be any 'name' or 'title' property where you could do something like this: var $tabs = $('contentContainer').tabs(); $tabs.tabs( 'title', index );

  • Selecting first instance of class but not nested instances via jQuery

    - by DA
    Given the following hypothetical markup: <ul class="monkey"> <li> <p class="horse"></p> <p class="cow"></p> </li> </ul> <dl class="monkey"> <dt class="horse"></dt> <dd class="cow"> <dl> <dt></dt> <dd></dd> </dl> <dl class="monkey"> <dt class="horse"></dt> <dd class="cow"></dd> </dl> </dd> </dl> I want to be able to grab the 'first level' of horse and cow classes within each monkey class. But I don't want the NESTED horse and cow classes. I started with .children, but that won't work with the UL example as they aren't direct children of .monkey. I can use find: $('.monkey').find('.horse, .cow') but that returns all instances, including the nested ones. I can filter the find: $('.monkey').find('.horse, .cow').not('.cow .horse, .cow .cow') but that prevents me from selecting nested instances on a second function call. So...I guess what I'm looking for is 'find first "level" of this descendant'. I could likely do this with some looping logic, but was wondering if there is a selector and/or some combo of selectors that would achieve that logic.

  • How should I port this Prototype to JQuery?

    - by blu
    There is currently this Prototype code that does a PUT: new Ajax.Request(someUrl, { method: 'put', parameters: { 'foo': bar }, onSuccess: function(response) { } .bind(this) }); I found this post but the solution uses an extra parameter supported by RoR, however I am targeting an ASP.NET backend. I searched a bit and found that not all browsers support PUT operations so apparently this could fail in certain browsers? This is already in prod, so a direct port would be fine for now I suppose. As an aside, what is the deal with the bind(this) in the onSuccess function?

  • Making span clickable after prepend in jQuery

    - by Saif Bechan
    I have a DIV where some code is presented. When I hover on this DIV I want to present a button that toggles the comments inside the code block. So far I have this: $('.code-block').hover( function(){ $(this).prepend('<span class="code-block-control">toggle comments</span>'); }, function(){ $('.code-block-control',this).remove(); } ); $('.code-block-control').click( function(){ $('.comment').toggle(); } ); The span is presented when I hover over the code block. But when I click the span that is created nothing happens. Even if I change the click function to a simple alert nothing happens. Anyone have any idea on how to fix this.

  • jquery onclick function not firing with rails link_to_remote

    - by RahTha
    In the js file of the page, inside $(document).ready(function() {} i have $(".school a").live("click", function (e){ e.preventDefault(); ....; jsFunc(param1, param2, param3); }); Now the div with the class school has tags generated by rails link_to_remote with :url, :action, :before, :html. On clicking on this link it does all that it should do with regards to link_to_remote, but somehow the onclick event in the document.ready does not attach to it. Why would this be happening? The jsFunc all it does is post to a url async-ly, i figured out that stuffing that post url in the :before of the link_to_remote would work - but is there a more elegant way of just being able to use the attach functionality

  • jquery Ajax $.ajaxError

    - by cf_PhillipSenn
    I have a bunch of ajax calls that contain success and error conditions like this one: $.ajax({ url: 'Remote/State.cfc' ,type: "POST" ,data: { 'method': 'UpdateStateName' ,'StateID': StateID ,'StateName': StateName } ,success: function(result){ if (isNaN(result)) { $('#msg').text(result).addClass('err'); } else { $('#' + result + ' input[name="StateName"]').addClass('changed'); }; } ,error: function(msg){ $('#msg').text('Connection error').addClass('err'); } }); All the error conditions are the same. In other words, they all put the phrase "Connection error" in the msg id. Q1: Could I remove all these and replace them with $().ajaxError(function(myEvent, request, settings, thrownError) { $('#msg').text('Connection error').addClass('err'); }); Q2: How would you use myEvent and request to display a more informative error message?

  • jQuery and IE not playing nice

    - by Neurofluxation
    Hello, I have this section of code: function createDownload() { var category, format, specification, download; $('#submitform').click(function() { category = $('#cate').val(); format = $('#form').val(); specification = $('#spec').val(); if (category == "NULL" || format == "NULL" || specification == "NULL") { alert("Please select all options."); return false; } else { download = "pdfs/"+specification+format+category+".pdf"; window.open(download); } }); } Now... In Internet Explorer it says there is an "Error on the page" - Message: 'return' statement outside of function and I have to click the button again. In Firefox, Chrome and Safari - I have to click the button twice to get the PDF to appear... (and no errors)... Now why could that be?! As per request - My Form declaration: <form method="post" action="javascript: return false;" onSubmit="createDownload();">

  • jquery simplemodal question (about window overflow)

    - by Matthew Steiner
    I noticed that if the height of the window is too small (meaning that the modal is taller than the window is), then even scrolling up or down won't reveal more of the modal, since it is constantly centering itself to the center of the window. Is there a good way of changing this? I have a tall modal that if someone's using a short monitor it may cause problems. Not to mention just general usability. I would guess that somewhere in the code you can test for if the window height is less than the modal to not worry about centering it vertically? Ideas?

  • 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... } ]

  • jQuery accordion link issue

    - by Josh
    Slight problem, I've been working with a multi-accordion for a News panel. Everything is working fine, but there is an issue that has just recently come up. Underneath the headline I have information on when said headline+article was posted and when, and also if there are any comments. I intended to make the author and the number of comments as a link. The author link would most likely bring them to their contact page or maybe an email, the number of comments link would just expand it directly to the "View comments" which the user could also access by just expanding the article and then expanding the comments. A shortcut basically. Now, the issue is that I'm having to put this "Posted by..." information inside the a class which allows the user to expand the headline into the article. If I do this however, it breaks the entire accordion field for that headline because there are multiple A HREF links inside the original A link. I really don't know how to get around this, if anyone has a tip or a solution I would most appreciate it, thanks. You can view the demo here: http://www.notedls.com/demo

  • Getting value from key pair value into appended property using jQuery

    - by Neil
    How do I get the value from a key pair value into the rel property of an anchor tag? When I split the code to put the value in the correct place it doesn't work, the end of the a tag would appear on screen instead value wouldn't be applied. When I look at the resulting code in console in Firebug the rel and href swapped order so the rel is first. The 'key' should be and is in the correct location but the 'value' needs to be applied to the rel attribute. What am I doing wrong? $(function() { var obj = {"firstThing":"4","secondThing":"6","aThirdThing":"2","anotherThing":"3","followedByAnother":"4"}; $.each(obj, function(key,value) { $('#newmine').append("<li class='tagBlocks'>","<a href='#' rel=''>",value," ",key); }); });
