• Using "null" in jQuery functions. Is this okay?

  - by Nick

  My database consists of some entries which are NULL (so they don't affect max, min, etc..). When I pull all of the data from the database, I need to repopulate form fields with the values. Using .val(value) where value = NULL seems to work without any problems, but I'm not sure if this is a valid way to go about this. It doesn't say anything in the jQuery documentation (that I can find) about using NULL as parameters to functions.

• Function of: if(/(file|http).*/.test(url)) { }

  - by WmasterJ

  I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code: var url = document.getElementById("editorURL").value; if(/(file|http).*/.test(url)) { } Maybe someone has a link to an article that explains this a bit more in-depth?

• Coffeescript getting proper scope from callback method

  - by pandabrand

  I've searched for this and can't seem to find an successful answer, I'm using a jQuerey ajax call and I can't get the response out to the callback. Here's my coffeescript code: initialize: (@blog, @posts) -> _url = @blog.url _simpleName = _url.substr 7, _url.length _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128' $.ajax url: _avatarURL dataType: "jsonp" jsonp: "jsonp" (data, status) => handleData(data) handleData: (data) => console.log data @avatar = data Here's the compiled JS: Blog.prototype.initialize = function(blog, posts) { var _avatarURL, _simpleName, _url, _this = this; this.blog = blog; this.posts = posts; _url = this.blog.url; _simpleName = _url.substr(7, _url.length); _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128'; return $.ajax({ url: _avatarURL, dataType: "jsonp", jsonp: "jsonp" }, function(data, status) { return handleData(data); }); }; Blog.prototype.handleData = function(data) { console.log(data); return this.avatar = data; }; I've tried a dozen variations and I can't figure out how to write this? Thanks.

• jQuery only firing last class in multiple-class click

  - by user1134644

  I have a set of links like so: <a href="#internalLink1" class="classA">This has Class A</a> <a href="#internalLink2" class="classB">This has Class B</a> <a href="#internalLink3" class="classA classB">This has Class A and Class B</a> And here's the corresponding jQuery: $('.classA').click(function(){ // do class A stuff }); $('.classB').click(function(){ // do class B stuff }); Currently, when I click on the first link with Class A, it does the Class A stuff like it's supposed to. Similarly, when I click on the second link with Class B, it does the Class B stuff like it's supposed to. No worries there. My issue is, when I click on the third link with BOTH classes, it only fires the function for whichever class comes last (in this case, class B. If I put class A at the end instead, it performs class A's function). I want it to fire both. What am I doing wrong? Thanks in advance. EDIT: To those posting fiddles, nearly all of them work, so as many have said, it's most likely not my code, but the way it displays in my file. For a little more clarification, I was teaching myself some jQuery and decided to try making a (very) simple "Choose Your Own Adventure" type game. Here's a jsfiddle containing the opening of my bare-bones-please-don't-laugh game. Click on "Hide in the bushes", then "Examine the victim", then "Take any valuables and leave, he's dead already" <-- THIS is where the issue is. It's supposed to add 98 gold ("hawks") to your inventory, AND tell you that your alignment has shifted 1 point towards Chaotic. At the moment, it only does the chaotic alert, and no gold gets added to your inventory. The other option (refresh the fiddle to restart) that adds money to your inventory, but DOES NOT make you chaotic, works just fine (if you select "Search him for identification" instead of "take the money and run") Sorry this is so long!

• I can get access to object's properties if method is called from anonymous function, but I can't do

  - by Kirzilla

  Hello, $.Comment = function() { this.alertme = "Alert!"; } $.Comment.prototype.send = function() { var self = this; $.post( self.url, { 'somedata' : self.somedata }, function(data) { //using anonymous function to call object's method self.callback(data); } ); } $.Comment.prototype.callback = function(data) { alert(this.alertme); } This code works great when I'm calling $.Comment.send(), but this code won't work... $.Comment.prototype.send = function() { var self = this; $.post( self.url, { 'somedata' : self.somedata }, self.callback //using direct access to method ); } Please, could you explain me why? Thank you

• jQuery Swap Image on Click and if/else

  - by jrutter

  Im stuck, Im setting a variable when someone clicks, then testing with if to see if the variable exists and doing something else. Its a simple script which Im probably overthinking, would love someone's thoughts. $('.view-alternatives-btn').live('click', function() { //$("#nc-alternate-wines").scrollTo(); //$('.nc-remove').toggle(); var showBtn = null; if (showBtn == null) { $('.view-alternatives-btn img').attr("src","../images/wsj_hide_alternatives_btn.gif"); $('#nc-alternate-wines').show(); showBtn = 1; console.log(showBtn); } else if (showBtn == 1) { $('.view-alternatives-btn img').attr("src","../images/wsj_view_alternatives_btn.gif"); $('#nc-alternate-wines').hide(); console.log("this " + showBtn); } return false; });

• Hide 'Would you like to remember password' iFrame

  - by nsilva

  Basically I have a website called http://yellow-taxis.uk/ which features an online booking system that is placed on the web site within an iFrame. On the online booking, it automatically logs the user in as a 'Guest' for credit card payments. When the site loads it comes up with a window asking the viewer if they 'would like to remember the password'. I was wondering if there was anyway possible to not display this window as it would be a much simpler option than changing a lot of the code within the online booking. Just to add, the iFrame is hosted on the same server as the web site (not sure if this makes a difference) Any help would be much appreciated.

• mailto: anchor links unloading html5 video in Chrome

  - by Robin Pyon

  I have a very simple page with a <video> tag and an email anchor link: http://jsfiddle.net/6GquX/3/ Clicking the email link in Chrome (OS X 10.8 + Win7, 23.0.1271.97) invokes the beforeunloadchange event and causes the video to unload, which isn't the desired outcome. Curiously enough, if I let the video buffer a bit and then click the email link, the video keeps playing and doesn't unload. To my knowledge this only occurs in Chrome and I'm truly at a loss. Visiting any HTML5 video player site (videojs, flowplayer etc), starting a HTML5 video and then immediately simulating an email click with document.location.href = "mailto:[email protected]" in the dev console yields the same error. However, I'm inclined to think it's the way in which the video has been encoded as I'm unable to recreate the above with a video downloaded from YouTube's HTML5 player: http://jsfiddle.net/6GquX/4/ (source) 1. Is it possible that YouTube are encoding their videos in a particular way to combat this? 2. Are there any strategies / hacks I can employ to get around this?

• What are some jQuery plugins that you've desired?

  While I'm pretty sure this might just get closed, I might just have some free time on my hands so I'm opening a request thread to see if anyone desires a jQuery plugin that I might be able to provide - if you have a specific request for a plugin that you can't find which isn't overly demanding ( such as a game ) can you reply to this thread?

• Divs don't toggle

  - by stackoverflowuser

  I have following divs on my page <div id="rpttimeline">div 1</div> <div id="rptareaview">div 2</div> <div id="rptgalleria">div 3</div> <div id="rptremainingwork">div 4</div> <div id="rptremainingspec">div 5</div> <div id="rptremainingreq">div 6</div> <div id="rptremaininguserstory">div 7</div> Initially through css I have the first two divs set to visible and the remaining are hidden. in my document ready function I have $(document).ready(function () { window.setInterval(toggleDivs, 5000); }); function toggleDivs() { $('#rpttimeline').toggle(); $('#rptareaview').toggle(); $('#rptgalleria').toggle(); $('#rptremainingwork').toggle(); $('#rptremainingspec').toggle(); $('#rptremainingreq').toggle(); $('#rptremaininguserstory').toggle(); } when toggledivs is called the first two divs get hidden but the other divs are not visible. It seems the toggle is affecting just the first two divs. Am I missing something here?
