  • get mouse position with respect to parent element

    - by ZX12R
    this is my setup <div id="uxcParent"> <div id="uxcClickable"></div> </div> now when a user clicks in the inner element i want the mouse position with respect to the parent div and not the page. this what i tried. var x= e.pageX- obj.offsetLeft; var x= e.pageY- obj.offsetTop; this works fine only when i don't scroll the page. I want the function to return the same values no matter where my elements are on the same page.

  • FB Developer: Capture POST variables after multi-friend-selector

    - by Faruz
    Using this: http://stackoverflow.com/questions/820421/can-i-use-facebooks-fbfriend-selector-in-an-iframe I created a multi-friend selector in my IFRAME FB application. I want to know if the user selected any users for invite so I can reward him with extra points. In the developer WIKI I saw that [ids] is transferred to requested page via POST. But how I can capture the values if I'm using JS/.NET? (Preferably through .NET so I can easily save values in the DB).

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • What's the difference between reflow and repaint?

    - by Jon Raasch
    I'm a little unclear on the difference between reflow + repaint (if there's any difference at all) Seems like reflow might be shifting the position of various DOM elements, where repaint is just rendering a new object. E.g. reflow would occur when removing an element and repaint would occur when changing its color. Is this true?

  • Hotkey to toggle checkboxes does opposite

    - by Joel Harris
    In this jsFiddle, I have a table with checkboxes in the first column. The master checkbox in the table header functions as expected toggling the state of all the checkboxes in the table when it is clicked. I have set up a hotkey for "shift-x" to toggle the master checkbox. The desired behavior when using the hotkey is: The master checkbox is toggled The child checkboxes each have their checked state set to match the master But what is actually happening is the opposite... The child checkboxes each have their checked state set to match the master The master checkbox is toggled Here is the relevant code $(".master-select").click(function(){ $(this).closest("table").find("tbody .row-select").prop('checked', this.checked); }); function tickAllCheckboxes() { var master = $(".master-select").click(); } //using jquery.hotkeys.js to assign hotkey $(document).bind('keydown', 'shift+x', tickAllCheckboxes); This results in the child checkboxes having the opposite checked state of the master checkbox. Why is that happening? A fix would be nice, but I'm really after an explanation so I can understand what is happening.

  • Hotkeys in webapps

    - by Johoo
    When creating webapps, is there any guidelines on which keys you can use for your own hotkeys without overriding too many of the browsers default hotkeys. For example i might want to have a custom copy command for copying entire sets of data that only makes sense for my program instead of just text. The logical combination for this would be ctrl+c but that would destroy the default copy hotkey for normal text. One solution i was thinking about is to only catch the hotkey when it "makes sense" but when you use some advanced custom selection it might be hard to differentiate if your data is focused, if text is selected or both. Right now i am only using single keys as the hotkey, so just 'c' for the example above and this seems to be what most other sites are doing too. The problem is that if you have text input this doesn't work so good. Is this the best solution? To clarify I'm talking about advanced webapps that behave more like normal programs and not just some website presenting information(even though i think these guidlines would be valid for both cases). So for the copy example it might not be a big deal if you can't copy the text in the menu but when ctrl+tab, alt+d or ctrl+e doesn't work i would be really pissed, cough flash cough.

  • How to stop toggle event from being fired multiple times on mouseenter/mouseleave?

    - by Clean
    Hi, I'm using jQuery to toggle the visibility of a using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the a few times and then leaves the , the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the are. Do anyone have any idea on how I can avoid this behavior? Thanx!

  • Changing a Variable Out of Scope?

    Is there any way to change a variable while out of scope? I know in general, you cannot, but I'm wondering if there are any tricks or overrides. For example, is there any way to make the following work: function blah(){ var a = 1 } a = 2; alert(blah());

  • Why can't I add an event to each element in a collection that refers to Itself rather than the last

    - by user311403
    On Window's load, every DD element inside Quote_App should have an onCLick event appended that triggers the function Lorem, however, Lorem returns the nodeName and Id of the last element in the For statement rather than that of the element that trigged the function. I would want Lorem to return the nodeName and Id of the element that triggered the function. .js function Lorem(Control){ /* this.Control=Control; */ this.Amet=function(){ return Control.nodeName+"\n"+Control.id; }; }; function Event(Mode,Function,Event,Element,Capture_or_Bubble){ if(Mode.toLowerCase()!="remove"){ if(Element.addEventListener){ if(!Capture_or_Bubble){ Capture_or_Bubble=false; }else{ if(Capture_or_Bubble.toLowerCase()!="true"){ Capture_or_Bubble=false; }else{ Capture_or_Bubble=true; }; }; Element.addEventListener(Event,Function,Capture_or_Bubble); }else{ Element.attachEvent("on"+Event,Function); }; }; }; function Controls(){ var Controls=document.getElementById("Quote_App").getElementsByTagName("dd"); for(var i=0;i Currently you click on any DD element Lorem always returns the nodeName and Id of the last DD element. Lorem should return the nodeName and Id of the Control (Control[i]) that triggered Lorem. How do I go about making this happen? Thank you!

  • jQuery Text to Link Script?

    - by Elijah Manor
    Does anyone know of a script that can select all text references to URLs and automatically replace them with anchor tags pointing to those locations? For example: http://www.google.com would automatically turn into <a href="http://www.google.com">http://www.google.com</a> Note: I am wanting this because I don't want to go through all my content and wrap them with anchor tags.

  • Designing code for a duo Website + AIR desktop App

    - by faB
    I want to use AIR to create an OFFLINE version of a "webapp" kind of website (lots of ajax, front end code). Haven't been much further than the HelloWorld example, I keep wondering: how do you design your code, to maximize code reuse between the website (say in php or Java or .Net), and the AIR app ? Can you actually re-use 100% of the front end code, provided that it is designed to account for the AIR app ? How would you go about doing that ? For example, the website makes many Ajax calls which have latency, and uses listeners. The AIR app doesn't need listeners it could run database requests synchronously, and it doesn't need to run ajax calls right? Would you write an abstraction layer for that ? So that the same calls on the AIR app will not do a xmlhttp but instead implement the server-side code with AIR; and call the listener ? So you don't have to rewrite the front end code patterns ? Does this make sense ? It's really hard to search on Google. I'm thinking there must be a good article somewhere of somebody who went through and perhaps a framework to do that ?

  • Jquery and frames

    - by Shard
    I am currently working on a web application that has been created using a magnitude of frames that stretch down up to 5 times, The issue is that i need to preform some jquery magic throughout the website. What would be the best way to go about this (other than rewriting it which i have considered)? EDIT: The Frame Structure is something along the lines of this: Index.html menu.html banner.html list.html footer.html /lib/index.html header.html body.html footer.html The magic i am referencing is a few hot key shortcuts, find and replace that kind of stuff

  • Jquery - intercept links created by ajax request

    - by Kaskade
    Hi, I have some jquery code that intercepts links clicked on a page : $(document).ready(function() { $("a").click(function() { //do something here }); }); My problem is there are certain parts of the page that have not finished loading on document ready. They are populated via ajax calls. The links in these sections are not intercepted by my jQuery function above. I need the function to be run on document ready initially but then I need the new links to also have the same logic applied to them. Any help would be very much appreciated. This is an area that I am very unfamiliar with. I have written the jQuery stuff but the ajax code is an external component that I have no control over. Thanks in advance
