  • Iterating Through a jQuery Object Array

    - by DeltaFox
    I know this has been asked and answered a couple times already, but I'm still confused about how to reference the current object when iterating over a jQuery array. For example, the following code gives me the error "TypeError: genH3Array[i].next is not a function". What is the right way to reference the current array object? var genH3Array = $('#Generation_II').parent(); genH3Array.push($('#Generation_III').parent());; genH3Array.push($('#Generation_IV').parent()) $.each(genH3Array, function(i, value) { if(genH3Array[i].next().attr("align") == "center") { genH3Array[i].next().next().next().insertBefore(heading.next()) } genH3Array[i].next().next().insertBefore(heading.next()) genH3Array[i].next().insertBefore(heading.next()) })

  • class selector refuses after append to body

    - by supersize
    I'm appending loads of divs in a wrapper: var cubes = [], allCubes = '', for(var i = 0; i < 380; i++) { var randomleft = Math.floor(Math.random()*Math.floor(Math.random()*1000)), randomtop = Math.floor(Math.random()*Math.floor(Math.random()*1000)); allCubes += '<div id="cube'+i+'" class="cube" style="position: absolute; border: 2px #000 solid; left: '+randomleft+'px; top: '+randomtop+'px; width: 9px; height: 9px; z-index: -1"></div>'; } $('#wrapper').append(allCubes); // performance for(var i = 0; i < 380; i++) { cubes.push($('#cube'+i)); } and then I would like to make them all draggable with jQueryUI and log their current position. var allc = $('.cube'); allc.draggable().on('mouseup', function(i) { allc.each(function() { var nleft = $(this).offset().left; var ntop = $(this).offset().top; console.log('cubes['+i+'].animate({ left:'+nleft+',top:'+ntop+'})'); }); }); Unfortunenately it does not work. They are neither draggable nor there comes up a log. Thanks

  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • Caller property of JS for "foo = function()" style of coding

    - by arvind
    I want to use the property of "caller" for a function which is defined here It works fine for this style of function declaration function g() { alert(g.caller.name) // f } function f() { alert(f.caller.name) // undefined g() } f() JSfiddle for this But then my function declaration is something like g = function() { alert(g.caller.name) // expected f, getting undefined } f = function() { alert("calling f") alert(f.caller.name) // undefined g() } f() and I am getting undefined (basically not getting anything) JSfiddle for this Is there any way that I can use the caller property without having to rewrite my code? Also, I hope I have not made any mistakes in usage and function declaration since I am quite new to using JS.

  • Which other event handler than click could i use?

    - by Gaelle
    I have a jQuery question, and I really think it is a silly one : i'm a beginner in JS and jQuery... I'm using $("#myLink").click(function(){ $(".myClassToShow").show(); $(".myClassToHide").hide(); }); to hide elements with class myClassToHide as a class attribute and show elements with class myClassToShow as a class attribute. I think this is really easy to understand :) I didn't think it would hide every elements with the good class, but, well, it works. My worry here is that my elements show and hide only for few seconds : the time my mouse click on the link. I would like to make myClassToShow elements remaining on the screen, when i already clicked my link, and myClassToHide elements really hide. For example, on the johann Hammarstrom's website, when you click on "Print", all his works which are not print gone hide, and only the printing one remain. That's kinda what i want. I searched using Firebug, but couldn't find which kind of event he used. I know a onchange is not the correct answer, so what? Could you help me please?

  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

  • Concatenate an each loop inside another

    - by Lothar
    I want to to concatenate the results of a jquery each loop inside of another but am not getting the results I expect. $.each(data, function () { counter++; var i = 0; var singlebar; var that = this; tableRow = '<tr>' + '<td>' + this.foo + '</td>' + $.each(this.bar, function(){ singlebar = '<td>' + that.bar[i].baz + '</td>'; tableRow + singlebar; }); '</tr>'; return tableRow; }); The portion inside the nested each does not get added to the string that is returned. I can console.log(singlebar) and get the expected results in the console but I cannot concatenate those results inside the primary each loop. I have also tried: $.each(this.bar, function(){ tableRow += '<td>' + that.bar[i].baz + '</td>'; }); Which also does not add the desired content. How do I iterate over this nested data and add it in the midst of the table that the primary each statement is building?

  • getting BR-separated text via DOM in JS/JQuery?

    - by Hellion
    Hi all, I am writing a greasemonkey script that is parsing a page with the following general structure: <table> <tr><td><center> <b><a href="show.php?who=IDNumber">(Account Name)</a></b> (#IDNumber) <br> (Rank) <br> (Title) <p> <b>Statistics:</b> <br> <table> <tr><td>blah blah etc. </td></tr></table></center></table> I'm specifically trying to grab the (Title) part out of that. As you can see, however, it's set off only by a <BR> tag, has no ID of its own, is just part of the text of a <CENTER> tag, and that tag has a whole raft of other text associated with it. Right now what I'm doing to get that is taking the innerHTML of the Center tag and using a regex on it to match for /<br>([A-Za-z ]*)<p><b>Statistics/. That is working okay for me, but it feels like there's gotta be a better way to pick that particular text out of there. ... So, is there a better way? Or should I complain to the site programmer that he needs to make that text more accessible? :-)

    I'm trying to print a specific part of my application. The application has a list of users, displaying their first and last name.

  • [jQuery] Any HTML tags inside of tooltip cause basic tooltip to close on hover.

    - by Christian
    Hi. I'm new to jQuery, in fact any kind of AJAX / JavsScript (although not new to PHP, xHTML and CSS). Anyway I'm trying to achieve a "tooltip-like" effect, where I can hover over a div...the new div fades in above it and then when I exit the div the "tooltip" fades out. So here's the basic jQuery I've managed to scrap together reading the odd guide here and there: $(function() { $('#sn-not-logged-in').hover(function() { $('#sn-not-logged-in-hover').fadeIn('medium'); }); $('#sn-not-logged-in-hover').mouseout(function() { $('#sn-not-logged-in-hover').fadeOut('medium'); }); }); Problem is if I put "any" html tag inside the div that hovers in, the second you roll over it the div fades back out. Any ideas how this can be fixed? Cheers.

  • What is this weird script I found on facebook?

    - by Mike Turley
    Not so much a question to help my own programming, but I found this page on facebook with a cool illusion and a page that says "to see the real illusion, copy and paste this code into your address bar" and there is a script: http://pastebin.com/LQUVQ8hm What the hell is this? What would happen if I put it in my address bar, which I assume would be a very unwise idea? I am confused.

  • Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?
