  • Passing a var as an argument

    - by Lienau
    On a site I'm making I need to have a progress bar, I found one that suited my needs. By default it will incrementally change the color when a certain percentage is reached (0-30 red, 30-70 orange, etc). My only problem is changing them, I can set them easily with a static number such as 50, but when I try to do it dynamically (ie: 2000*.3 = 600) it fails. I don't know much js/jquery so this is especially difficult for me, if you could help that would be great. I'm pretty sure it's something really simple I'm missing. The code that Fails: var barmax = 2000; var orangeBound = Math.round(barmax * .3); var greenBound = Math.round(barmax * .7); //alert(orangeBound+":"+greenBound); $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', orangeBound: 'images/progressbg_orange.gif', greenBound: 'images/progressbg_green.gif'} }); The code that works but I can't use because it has to be dynamic: $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', 600: 'images/progressbg_orange.gif', 1400: 'images/progressbg_green.gif'} }); If you need to see the source, here. Thanks again!

  • jQuery gallery turn over with next and previous buttons

    - by Ralf
    Hi, i'm trying to do some kind of Gallery-Turn Over Script with jQuery. Therefor i got an array with - let's say 13 - images: galleryImages = new Array( 'images/tb_01.jpg', 'images/tb_02.jpg', 'images/tb_03.jpg', 'images/tb_04.jpg', 'images/tb_05.jpg', 'images/tb_06.jpg', 'images/tb_07.jpg', 'images/tb_08.jpg', 'images/tb_09.jpg', 'images/tb_10.jpg', 'images/tb_11.jpg', 'images/tb_12.jpg', 'images/tb_13.jpg' ); My gallery looks like a grid showing only 9 images at once. My current script already counts the number of li-elements in #gallery, loads the first 9 images and displays them. The HTML looks like this: <ul id="gallery"> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> <li></li> </ul> <ul id="gallery-controls"> <li id="gallery-prev"><a href="#">Previous</a></li> <li id="gallery-next"><a href="#">Next</a></li> </ul> I'm pretty new to jQuery an my problem is that i can't figure out how to split the array in portions with 9 elements to attach it as a link on the control buttons. I need something like this: $('#gallery-next').click(function(){ $('ul#gallery li').children().remove(); $('ul#gallery li').each(function(index,el){ var img = new Image(); $(img).load(function () { $(this).css('display','none'); $(el).append(this); $(this).fadeIn(); }).attr('src', galleryImages[index]); //index for the next 9 images?!?! }); }); Thanks for help!

  • jquery ui autocomplete does't close options menu if there is no focus when ajax returns

    - by Uri
    I'm using jquery ui autocomplete widget with ajax, and on noticed the following problem. Background: In order for the user to be able to focus on the autocomplete and get the options without typing anything, I use the focus event: autoComp.focus(function() { $(this).autocomplete("search", "");} However this produces the following effect: when the user clicks, an ajax request is being sent. While waiting for the response, the user then clicks elsewhere and the autocomplete is blurred. But as soon as the response returns, the options menu pops out, even though the autocomplete has no focus. In order to make it go away the user has to click once inside, and again outside the autocomplete, which is a bit annoying. any ideas how I prevent this? EDIT: I solved this in a very ugly way by building another mediator function that knows the element's ID, and this function calls the ajax function with the ID, which on success check the focus of the element, and returns null if it's not focused. It's pretty ugly and I'm still looking for alternatives. EDIT#2: Tried to do as Wlliam suggested, still doesn't work.. the xhr is undefined when blurring. Some kind of a problem with the this keyword, maybe it has different meanings if I write the getTags function outside of the autocomplete? this.autocomplete = $('.tab#'+this.id+' #tags').autocomplete({ minLength: 0, autoFocus: true, source: getTags, select: function(e, obj) { tab_id = $(this).parents('.tab').attr('id'); tabs[tab_id].addTag(obj.item.label, obj.item.id, false); $(this).blur(); // This is done so that the options menu won't pop up again. return false; // This is done so that the value will not stay in the input box after selection. }, open: function() {}, close: function() {} }); $('.tab#'+this.id+' #tags').focus(function() { $(this).autocomplete("search", ""); }); $('.tab#'+this.id+' #tags').blur(function() { console.log('blurring'); var xhr = $(this).data('xhr'); // This comes out undefined... :( if (xhr) { xhr.abort(); }; $(this).removeClass('ui-autocomplete-loading'); }); and this is the getTags function copied to the source keyword: function getTags(request, response) { console.log('Getting tags.'); $(this).data('xhr', $.ajax({ url: '/rpc', dataType: 'json', data: { action: 'GetLabels', arg0: JSON.stringify(request.term) }, success: function(data) { console.log('Tags arrived:'); tags = []; for (i in data) { a = {} a.id = data[i]['key']; a.label = data[i]['name']; tags.push(a); } response(tags); } })); console.log($(this).data('xhr')); }

  • jQuery tooltip: Trouble with remove()

    - by Rosarch
    I'm using a jQuery tooltip plugin. I have HTML like this: <li class="term ui-droppable"> <strong>Fall 2011</strong> <li class="course ui-draggable">Biological Statistics I<a class="remove-course-button" href="">[X]</a></li> <div class="term-meta-data"> <p class="total-credits too-few-credits">Total credits: 3</p> <p class="median-GPA low-GPA">Median Historical GPA: 2.00</p> </div> </li> I want to remove the .course element. So, I attach a click handler to the <a>: function _addDeleteButton(course, term) { var delete_button = $('<a href="" class="remove-course-button" title="Remove this course">[X]</a>'); course.append(delete_button); $(delete_button).click(function() { course.remove(); return false; }).tooltip(); } This all works fine, in terms of attaching the click handler. However, when course.remove() is called, Firebug reports an error in tooltip.js: Line 282 tsettings is null if ((!IE || !$.fn.bgiframe) && tsettings.fade) { What am I doing wrong? If the link has a tooltip attached, do I need to remove it specially? UPDATE: Removing .tooltip() solve the problem. I'd like to keep it in, but that makes me suspect that my use of .tooltip() is incorrect here.

  • Get status of servlet request before the response is returned

    - by Alex
    Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by repeating the same calculations 1000s of times. I would be interested to know if anyone has ever tried to use client side technology to provide any estimate of the percentage complete. I.e query the servlet processing to get the number of cycles completed at various point throughout the simulation. This could then be displayed as a bar in the client browser. Any thoughts, advice, resources would be much appreciated. Thanks, Alex

    - by James
    Hello, When using the "Connect" facebook connect button, when I click it, it opens up a new popup window outside of the current window. This is quite annoying, how am I able to use the inline modal dialog that is found on most sites? I've attached a sample site to see if you can make anything out of it. http://bit.ly/c9Emi Thank you.

  • Pass variables to current tab via chrome extension

    - by iamthejeff
    I am writing my first chrome extension, and I want to pass a variable to the currently opened tab and manipulate the DOM with it. My extension has a button, and when clicked, is executing this code: chrome.tabs.getSelected(null, function(tab) { chrome.tabs.executeScript(tab.id, { file: 'tabscript.js' }); }); This works fine, but I see no way to pass a variable to tabscript.js so it can be used on the opened tab.

  • HTML wrapper div over embedded flash object cannot be "clickable" by jQuery

    - by Michael Mao
    Hi all: I've been trying to do as the client requested : redirect to campaign page then to destination page once a customer clicks on the top banner in swf format. You can check what's been done at :http://ausdcf.org If you are using Firefox, Chrome or Safari, I suspect you can reach the destination page. However, if you are using IE or Opera, I doubt it. I think to cause of such a weird problem is: The swf ojbects don't have a link to url, SO I have to hack the theme template file like this : <div id="header">'; /* * A quick and dirty way to put some swf into PHP, and rotate among them ... */ //available banners $banners = array( 'http://localhost/smf/flash/banner_fertalign_1.swf', 'http://localhost/smf/flash/banner_fertalign_2.swf', 'http://localhost/smf/flash/banner_fertalign_3.swf' ); //get random banner srand((double) microtime() * 1000000); $rand = rand(0,count($banners)-1); echo '<div id="top_banner_clickable">'; echo '<div id="top_banner_wrapper">'; echo '<object width="400" height="60">'; echo '<param name="wmode" value="transparent">'; echo '<embed wmode="transparent" src="'.$banners[$rand].'" '; echo 'width="400" height="60" type="application/x-shockwave-flash"'; echo 'pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" />'; echo '</object>'; echo '</div>'; echo '</div>'; And the related jQuery code is like this: /* master.js */ $(document).ready(function() { $("#top_banner_clickable").click(function() { window.location ="http://ausdcf.org/campaign/"; }); }); I absolutely know nothing about Flash or embedded objects. I guess that's the cause of this problem. Plus, I don't know why it works with some browsers but not all... I even tried to add a z-index to the wrapper div in css like this: #top_banner_clickable { z-index : 100; } No this wouldn't do, either... Is there a way to go around this issue? Many thanks in advance.

  • Difficulty with MooTools Class.extend

    - by Erin Drummond
    Consider the following code: var Widget = new Class({ Implements: [Options], options: { "name" : "BaseWidget" }, initialize: function(options) { alert("Options are: " + JSON.stringify(options)); //alerts "Options are: undefined" this.setOptions(options); alert("My options are: " + JSON.stringify(this.options)); //alerts "My options are: { 'name' : 'BaseWidget' }" }, getName: function() { return this.options.name; } }); var LayoutWidget = Widget.extend({ initialize: function() { this.parent({ "name" : "Layout" }); } }); alert(new LayoutWidget().getName()); //alerts "BaseWidget" I am having difficulty in determining why the argument passed in the "this.parent()" call in "initialize" function of LayoutWidget is coming through as "undefined" in the initialize function of Widget. I am using MooTools 1.2.2. Would somebody be able to point me in the right direction?

  • Another IE Issue with AJAX

    - by Nik
    Alright, This code works in every browser except IE (again, to be expected). The code is supposed to refresh based on setInterval, and does so normally in all other browsers except IE, which just doesn't refresh. Can you spot the problem? var nick = document.getElementById("chatnick").value; var sessid = document.getElementById("sessid").value; var room = document.getElementById("roomid").value; function user_read() { $.ajax({ type: "GET", url: "methods.php", data: {method: "u", room: room}, dataType: "html", success: function (data, status, xhr) { $("#userwindow").html(data); setTimeout(user_read, 10000); } }); } function ajax_read() { $.ajax({ type: "GET", url: "methods.php", data: {method: "r", room: room}, dataType: "html", success: function (data, status, xhr) { $("#chatwindow").html(data); setTimeout(ajax_read, 400); } }); } function submit_msg() { var msg = document.getElementById("chatmsg").value; $.ajax({ type: "GET", url: "methods.php", data: {method: "w", room: room, m: msg, n: nick, sessid: sessid}, dataType: "html", success: function (data, status, xhr) { } }); document.getElementById("chatmsg").value = ""; } function keyup(arg1) { if (arg1 == 13) submit_msg(); } setTimeout(function(){ajax_read();}, 400); user_read();

  • Programmatically change an EditorGrid's cell value

    - by Snowright
    Hi, I have an Editor Grid where if a specific cell is in focus (is being edited), a window containing a tree panel pops up allowing the user to choose a node from the treepanel as the new value of the cell. This way, the user isn't actually editing the cell in question, but is using the window to choose the new value. However, I am having difficulties setting the value of the cell in question programmatically. Below is the code I use to set the grid up, including the column model that chooses what editor to use for a cell depending on the value type: var editorCM = new Ext.grid.ColumnModel({ //config ,editors : { //rest of editors 'id' : new Ext.grid.GridEditor(new Ext.form.TextField({readOnly : true})) } ,getCellEditor : function(col, row) { //choose editor depending on the type value of a cell } }) var editorGrid = new Ext.grid.EditorGridPanel({ //rest of config ,cm : editorCM }) Below is my code to change the cell's value once the user chooses from the treepanel. function submitNode(newValue) { var temp = editorGrid.GetSelectionModel().getSelectedCell(); //returns array containing column and row position of selected cell, which value we want to change. //temp[1] = column index, temp[0] = row index //Gets the cell editor at specific position and sets new value for that cell editorGrid.getColumnModel().getCellEditor(temp[1], temp[0]).setValue(newValue); } I've also tried a few other ways (all including setValue(newValue)), but have come up empty handed. I've looked through the API and the ExtJS forums for any clue but have also come up empty handed.

  • jQuery image hover color overlay

    - by Ryan Max
    I can't seem to find any examples of this having been done anywhere on the internet before but here is what I am going to attempt to do...I'm trying to go about the cleanest possible way of laying this out. So I have an image gallery where the images are all different sizes. I want to make it so that when you mouseover the image, it turns a shade of orange. Just a simple hover effect. I want to do this without using an image swap, otherwise I'd have to create an orange colored hover-image for each individual gallery image, I'd like this to be a bit more dynamic. My plan is just to position an empty div over the image absolutely with a background color, width and height 100% and opacity: 0. Then using jquery, on mouseover I'd have the opacity fade to 0.3 or so, and fade back to zero on mouseout. My question is, what would be the best way to layout the html and css to do this efficiently and cleanly. Here's a brief, but incomplete setup: <li> <a href="#"> <div class="hover">&nbsp;</div> <img src="images/galerry_image.png" /> </a> </li> .hover { width: 100%; height: 100%; background: orange; opacity: 0; }

  • Is there a way to create a step chart using the Google Charts API?

    - by Nathan
    I'd like to use the google charts API to create a step chart for my Rails application. Preferably using the annotated timeline Google has (since it has a nice wrapper plugin for rails): http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html However, there doesn't seem to be a way to create a step chart using the annotated timeline or any other chart in the Google API. I'm looking to make a plot like this: If there is no way to do this with the google API, is there an alternative graphing library that can handle such a task?
