  • Why does typeof NaN return 'number'?

    - by KooiInc
    Just out of curiosity. It doesn't seem very logical that typeof NaN is number. Just like NaN === NaN or NaN == NaN returning false, by the way. Is this one of the peculiarities of javascript, or would there be a reason for this?

  • Wait 300ms and then slide down menu using jQuery

    - by Derfder
    I tried this js code: <script type="text/javascript"> $(document).ready( function() { var timer; $('.top-menu-first-ul li').hover(function(){ if(timer) { clearTimeout(timer); timer = null } timer = setTimeout(function() { $(this).find('ul').slideToggle(100); }, 500) }, // mouse out }); }); </script> with this html: <ul class="top-menu-first-ul"> <li> <a href="http://google.com">Google</a> <ul class="top-menu-second-ul"> <li><a href="http://translate.google.com">Google Translate</a></li> <li><a href="http://images.google.com">Google Images</a></li> <li><a href="http://gmail.google.com">Gmail</a></li> <li><a href="http://plus.google.com">Google Plus</a></li> </ul> </li> <li> <a href="http://facebook.com">Facebook</a> </li> <li> <a href="http://twitter.com">Twitter</a> </li> </ul> but it is not working. I would like to show the submenu when hovering over e.g. Google link and other will appear after 300ms. So, I need to prevent loading submenu when the user just quickly hover over it and not stay on hover link for at least 300ms. Then I need to stop executing code (or slide up) when he leaves the link. Because if he go over and back and over and back a copule of times he stop doing hovering anfd the code is still executing itself how many times he had hover over the link. I need somehow prevent this to happen. EDIT: I need to solve this without plugins like hoverIntent etc. if possible, just plain javascript and jQuery

  • Can I use feature detection to know if css hover works for this client?

    - by user366061
    I've got a website that provides labels when the user hovers over an image. You can see the example at: http://www.185vfx.com/ For touchscreens, I'd like to have those hints on by default (since hover isn't usually available). I'd prefer not to browser-sniff and try to maintain that list as new devices/versions arrive. Any reliable way to detect if a browser can respond to hover or otherwise know about a touchscreen user via javascript or css?

  • Support for encoding query string or POST data in YUI ?

    - by faB
    How do you encode a javascript object/hash (pairs of properties and values) into a URL-encoded query string with YUI (2.7.0 or 3.0.0 Beta) ? I want to do the equivalent of Object.toQueryString() from Prototype: I need this to encode parameters for GET and POST requests with YAHOO.util.Connect. It turns out YAHOO.util.Connect has a setForm() method to serialize a form but that still leaves me out cold to encode parameters for GET requests, or the 4th parameter of YAHOO.util.Connect.asyncRequest() to pass post data.

  • is it possible to tell if DOM was modified, and which part?

    - by mkoryak
    Are there any practical ways to tell what part of the DOM was modified if you know that it will be modified? I am writing a plugin that will be running along with javascript that i did not write. an event will be triggered before DOM is modified, and one event will be triggered after the modification. It is my job to decide what was changed. is this possible, and if so what is the least horrible way to do this?

  • Dynamically moving div, like Yelp's moving map

    - by jeanh
    I am trying to implement something very similar to Yelp's moving map. See: http://www.yelp.com/search?find_desc=restaurants&ns=1&find_loc=mountain+view%2C+ca Basically it starts off somewhere in the middle of the page, but if you scroll down far enough that you wouldn't be able to see it, it moves down as well. What is the best way to do this in javascript? My app is in GWT, but I think I will have to use native js to achieve this effect. Thanks, Jean

  • Why doesn't my form post when I disable the submit button to prevent double clicking?

    - by John MacIntyre
    Like every other web developer on the planet, I have an issue with users double clicking the submit button on my forms. My understanding is that the conventional way to handle this issue, is to disable the button immediately after the first click, however when I do this, it doesn't post. I did do some research on this, god knows there's enough information, but other questions like Disable button on form submission, disabling the button appears to work. The original poster of Disable button after submit appears to have had the same problem as me, but there is no mention on how/if he resolved it. Here's some code on how to repeat it (tested in IE8 Beta2, but had same problem in IE7) My aspx code <%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <script language="javascript" type="text/javascript"> function btn_onClick() { var chk = document.getElementById("chk"); if(chk.checked) { var btn = document.getElementById("btn"); btn.disabled = true; } } </script> <body> <form id="form1" runat="server"> <asp:Literal ID="lit" Text="--:--:--" runat="server" /> <br /> <asp:Button ID="btn" Text="Submit" runat="server" /> <br /> <input type="checkbox" id="chk" />Disable button on first click </form> </body> </html> My cs code using System; public partial class _Default : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); btn.Click += new EventHandler(btn_Click); btn.OnClientClick = "btn_onClick();"; } void btn_Click(object sender, EventArgs e) { lit.Text = DateTime.Now.ToString("HH:mm:ss"); } } Notice that when you click the button, a postback occurs, and the time is updated. But when you check the check box, the next time you click the button, the button is disabled (as expected), but never does the postback. WHAT THE HECK AM I MISSING HERE??? Thanks in advance.

  • NewBie Question, jQuery: How can we implement if...else logic and call function

    - by Rachel
    I am new to jQuery and so don't mind this question if it sounds stupid but here is something that I am trying to do : I have 3 functions like: AddToCart Function which adds item to the shopping cart: //offer_id is the offer which we are trying to add to cart. addToCart: function(offer_id) { this.submit({action: 'add', 'offer_id': offer_id}, {'app_server_url': this.app_server_url}); }, RemoveFromCart which removes data from the cart //target is link clicked and event is the click event. removeFromCart: function(target, event) { this.uniqueElmt('cart_table').find('.sb_item_remove').unbind('click'); var offer_id = $(target).parent().find('.offer_id').html(); this.submit({action: 'remove', 'offer_id': offer_id, 'next_action': this.config.current_action}, {'app_server_url': this.app_server_url}); }, Get the current state of the cart //return string which represents current state of cart. getCartItems: function() { return this.contents; } Now I am trying to do 3 things: if there is no content in cart and addToCart is called than some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is Null and than if addToCart is called than we perform some action if there is content in the cart and addToCart is called than some action,so basically here we need to check the current state of cart and that is obtained by calling getCartItems and check if it is Null or not and than if addToCart is called than we perform some action if we had some content in the cart. if there is content in the cart and removeFromCart is called some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is not Null and if removeFromCart is called than we perform some action Pseudocode of what I am trying to do: if there is no content in cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd,scOpen', 'linkType' : 'o', 'linkName' : 'Cart : First Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd,scOpen', }, } 'defer' : '0' } ); if there is content in the cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd', 'linkType' : 'o', 'linkName' : 'Cart : Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd', }, }, 'defer' : '0' } ); if there is content in the cart and removeFromCart is called $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scRemove', 'linkType' : 'o', 'linkName' : 'Cart : Product Removed' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scRemove', }, } 'defer' : '0' } ); My basic concern is that am complete newbie to jQuery and JavaScript and so am not sure how can I implement if...else logic and how can I call a funtion using jQuery/JavaScript.

    Let me explain what I'm trying to do. I want to make a simple box which counts down numbers at intervals I specify. For example, I'd like to set it to start at 150, and then I want to set it to drop by 15 every 30 seconds. Is this possible with AJAX/Javascript? If so, could someone point me in the right direction? Would really appreciate any help on this script, been Googling for hours now! :( Cheers Kieran

  • Is there a client-side way to prevent an image from being cached?

    - by morgancodes
    Is it possible to control with javascript whether a browser goes to the server for an image or to the browser cache? Can I force the browser to make a server call when it would otherwise use a cached image? I know I can simply append a query string to my image url, but, if I understand correctly, that works because the browser sees that as a new image. I want the old image to be replaced in the cache.

  • Queuing asynchronous HTTP file uploads

    - by David Parunakian
    Is there a way to queue file uploads without resorting to Flash or Silverlight, just with cleverly used forms and JavaScript? Note that the upload should be executed asynchronously. By "queuing" uploads I mean that if the user tries to upload multiple files, they should not be transferred simultaneously, but rather one at a time, in a single HTTP connection.

  • Validate a number between 10 and 11 characters in length

    - by Montana Flynn
    I am using javascript (and PHP) to validate a simple form with a phone number field. I have it working fine checking that the field has only 10 characters, but I really want to check if the field has between 10 and 11 characters. Reason being, some people type numbers like so: 1 555 555 5555 and some people do this 555 555 5555. Here is what I have that works for checking if the length is 10: if (!(stripped.length == 10)) { alert("Please enter a valid US phone number.") return false }
