  • Is there a way to change the color of plots in jQuery flot without redrawing the whole chart?

    - by Sam Lee
    I have a chart that I'm drawing using flot. I want to change the colors of the data plots when someone hovers over text. Currently, I am doing this by redrawing the entire chart each time I need to highlight something. This is pretty slow (about 30 milliseconds for a simple chart, as much as 100 for a more complicated chart). Since all I want to do is change the color, is there a faster solution?

  • Use HTTParty methods in a subclass

    - by cpjolicoeur
    I'm trying to write an API wrapper in ruby and am stumped on how I can call HTTParty methods from a subclass. For instance, I want the user to create a connection to the api and then be able to query results from subclasses. module ApiWrapper class Connection include HTTParty base_uri '...' def initialize( u, p ) ... end def contacts ApiWrapper::Contact end end end module ApiWrapper class Contact def all # issue httparty get request here that is created from the Connection class end end end ## The user would do this conn = ApiWrapper::Connection.new( 'username', 'password' ) contacts = conn.contacts.all

  • How do I submit a form using jquery (ajaxForm plugin) to an external site but not reload to a differ

    - by Scott
    Hi, I'm trying to create a form that sends the customer's name and email address to icontact (an email list application). All the values are correct for icontact and if I submit the form as usual, icontact responds that it added the email address. The success message loads in a new page from icontact's website. What I'd like to accomplish is that ajax would send the form and returns a success message within the current page, without sending the customer to a new page. Here is the test page: http://www.skhot.com/test/js-test/forms/index.php

    - by sajad
    Hi Friends, I want to write a code to search for method defination and methods called in a c# file. So obviously my pattern should search for text like 1.public void xyz(blahtype blahvalue); 2.string construct = SearchData(blahvalue); Has anyone done similar to this, is Regex helpful in this case. if yes provide me the pattern. Any other workarounds. I dont know reflection(will it help in my case) Thanks, you guys gave it a try, i did not know this wud be so complex. All i wanted to do was suppose i have method like this public method1(int val) { method2(); method3(); } void method2(int val2) { method4() } i wanted to construct a string as Method1:Method2:method4 and Method1:Method3.... I guess its really complex

  • jquery google visual api graph's data rows does not work.

    - by marharépa
    Hi! I'd like to use google drawVisualization API. Example: var data = new google.visualization.DataTable(); data.addColumn('string'); data.addColumn('number'); data.addRows([ ['a', 14], ['b', 47], ['c', 80], ['d', 55], ['e', 16], ['f', 90], ['g', 29], ['h', 23], ['i', 58], ['j', 48] ]); My version gets elements by an other google api, and join them, and after place the variable between ([ and ]), to be like in the example. var outputGraph = []; for (var i = 0, entry; entry = entries[i]; ++i) { var asd = [ entry.getValueOf('ga:pageTitle'), entry.getValueOf('ga:pageviews') ].join("',"); outputGraph.push(" ['" + asd + "]"); //get the 2 elements and join them to be like ['asd', 2], } // this is fine, the outputgraph is like ['asd', 2], ['asd', 2], ['asd', 2] as seen in the example var outputGraphFine = ("(["+outputGraph+"])"); // i suggest this is which fails the script. var data = new google.visualization.DataTable(); data.addColumn('string', 'Task'); data.addColumn('number', 'Hours per Day'); data.addRows = outputGraphFine; But it doesn't work. Why?

  • Browsers disagree about the text of a body element

    - by Charles Anderson
    My HTML looks like this: <html> <head> <title>Test</title> <script type="text/javascript" src="jQuery.js"></script> <script type="text/javascript"> function init() { var text = jQuery('body').text(); alert('length = ' + text.length); } </script> </head> <body onload="init()">0123456789</body> </html> When I load this in Firefox, the length is reported as 10. However, in Chrome it's 11 because it thinks there's a linefeed after the '9'. In IE it's also 11, but the last character is an escape. Meanwhile, Opera thinks there are 12 characters, with the last two being CR LF. If I change the body element to include a span: <body onload="init()"><span>0123456789</span></body> and the jQuery call to: var text = jQuery('body span').text(); then all the browsers agree that the length is 10. Clearly it's the body element that's causing the issue, but can anyone explain exactly why this is happening? I'm particularly surprised because the excellent jQuery is normally browser-independent.

  • Calling UITableViews delegate methods directly.

    - by RickiG
    Hi I was looking for a way to call the edit method directly. - (void)tableView:(UITableView *)theTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath I have all my logic for animating manipulated cells, removing from my model array etc. in this method. It is getting called when a user swipes, adds or rearranges, but I would like to call it manually/directly as a background thread changes my model. I have constructed an NSIndexPath like so: NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:1]; I just can't figure out how to call something like: [self.tableview commitEditingStyle:UITableViewCellEditingStyleDelete forRowAtIndexPath:path]; Do I need to gain access to the methods of this plain style UITableView in another way? Thanks:)

  • jQuery autocomplete works with a local string but not when the same String is called off the server

    - by Ankur
    This is related to the question I asked at http://stackoverflow.com/questions/2802948/how-to-make-an-ajax-call-immediately-on-document-loading My code is: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = data; alert(dataArray); $("#example").autocomplete(dataArray); } }); }); The value that is printed in the alert is: "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); If instead I do this: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); alert(dataArray); $("#example").autocomplete(dataArray); } }); }); It works fine?

  • Prevent default on a click within a JQuery tabs in Google Chrome.

    - by Sydney
    I would like to prevent the default behaviour of a click on a link. I tried the return false; also javascript:void(0); in the href attribute but it doesn’t seem to work. It works fine in Firefox, but not in Chrome and IE. I have a single tab that loads via AJAX the content which is a simple link. <script type="text/javascript"> $(function() { $("#tabs").tabs({ ajaxOptions: { error: function(xhr, status, index, anchor) { $(anchor.hash).html("Couldn't load this tab. We'll try to fix this as soon as possible. If this wouldn't be a demo."); }, success: function() { alert('hello'); $('#lk').click(function() { alert('Click Me'); return false; }); } }, load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); }); </script> <body> <div id="tabs"> <ul> <li><a href="linkChild.htm">Link</a></li> </ul> </div> </body> The content of linkChild.htm is <a href="javascript:void(0)" id="lk">Click Me</a> So basically when the tab content is loaded with success, a click event is attached to the link “lk”. When I click on the link, the alert is displayed but then link disappears. I check the HTML and the element is actually removed from the DOM.

  • why including www in a jquery load causes it to fail?

    - by zenna
    Could someone enlighten me as to why including www in a ajax request causes it to fail. i.e. This works: $('#mydiv').load('http://mydomain.com/getitems'); But this doesn't (returns nothing) $('#mydiv').load('http://www.mydomain.com/getitems'); Note that www.mydomain.com/getitems is a valid domain, in the sense that if I point my web browser to it I am able to load the page.

  • Suppose i have an HTML table. How do I use JQuery events on this?

    - by alex
    <table> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> </table> How do I make the appropriate col1 fill with the letters "ABC" when the user rollovers the row? And then disappear the "ABC" when the user moves the mouse away from that row? So far, I got this. I solved it. $(".ep").hover(function(){ $(this).find('td.playButtonCol').html('PLAY'); },function(){ $(this).find('td.playButtonCol').html(''); });

  • Placement of service methods

    - by mhp
    Let's assume I have two service classes with the following methods: GroupService createGroup() deleteGroup() updateGroup() findGroup() UserService createUser() deleteUser() updateUser() findUser() Now, I am thinking about the aesthetics of theses classes. Imagine we want to implement a method which search for all user of a specific group. Which service class is responsible for such a method? I mean, the return value is a user (or maybe a collection of users) but the parameter (which means the name of the group) is a group. So which service class is the better place to put this method in?

  • Small methods - Small sprocs

    - by Berlioz
    Uncle Bob recommends having small methods. Do stored procedures have an ideal size? Or can they run on for 100's and 100's of lines long? Also does anyone have anything to say about where to place business logic. If located in stored procedures, the database is being used as data processing tier. If you read Adam Machanic, his bias is toward the database, does that imply long stored procedures that only the author of the sproc understands, leaving maintainers to deal with the mess? I guess there is two inter-related questions, somehow. Thanks in advance for responding to a fuzzy question(s).

  • How to make JCarousel Vertical Scroller reverse scroll?

For example right now I have: jQuery(document).ready(function() { jQuery('#mycarousel').jcarousel({ auto: 1, vertical: true, scroll: 1, animation: "slow", wrap: 'last', initCallback: mycarousel_initCallback }); }); What do I need to do to make the items scroll upwards instead of downwards?

  • What is wrong with the JavaScript event handling in this example? (Using click() and hover() jQuery

    - by Bungle
    I'm working on a sort of proof-of-concept for a project that approximates Firebug's inspector tool. For more details, please see this related question. Here is the example page. I've only tested it in Firefox: http://troy.onespot.com/static/highlight.html The idea is that, when you're mousing over any element that can contain text, it should "highlight" with a light gray background to indicate the boundaries of that element. When you then click on the element, it should alert() a CSS selector that matches it. This is somewhat working in the example linked above. However, there's one fundamental problem. When mousing over from the top of the page to the bottom, it will pick up the paragraphs, <h1> element, etc. But, it doesn't get the <div>s that encompass those paragraphs. However, for example, if you "sneak up" on the <div> that contains the two paragraphs "The area was settled..." and "Austin was selected..." from the left - tracing down the left edge of the page and entering the <div> just between the two paragraphs (see this screenshot) - then it is picked up. I assume this has something to do with the fact that I haven't attached an event handler to the <body> element (where you're entering the <div> from if you enter from the left), but I have attached handlers to the <p>s (where you're entering from if you come from the top or bottom). There are also other issues with mousing in and out elements - background colors that "stick" and the like - that I think are also related. As indicated in the related question posted above, I suspect there is something about event bubbling that I don't understand that is causing unexpected behavior. Can anyone spot what's wrong with my code? Thanks in advance for any help!

  • How would i go about showing the closest paragraph element to a unique link with jQuery?

    - by Nike
    The title is a bit rusty, sorry about that. Now let me explain what i'm trying to do. I have a few listed items, like this: <li> <a id="toggle" class="0"><h4>ämne<small>2010-04-17 kl 12:54</small></h4></a> <p id="meddel" class="0">text</p> </li> <li class='odd'> <a id="toggle" class="1"><h4>test<small>2010-04-17 kl 15:01</small></h4></a> <p id="meddel" class="1">test meddelande :) [a]http://youtube.com[/a]</p> </li> The function i'm trying to achieve, is that when a user clicks a "toggle" link (the h4 text), i want the paragraph element below it to fade in. I thought of the idea of giving both the toggle link and the paragraph the same class, and then somehow make it get the paragraph with the same class as the toggle link clicked, and show it? But i'm not entirely sure how to do that either, and tbh, it doesn't sound like the greatest idea, but maybe that's the only way? I don't know... Is there some way to just simply get the nearest paragraph (below the link) with the id "meddel" and fade it in? That sounds a bit easier... I hope you can at least give me a few hints. Thanks in advance, -Nike
