  • Can I access an iframe of the same domain in a separate window?

    - by jozecuervo
    How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

  • What is the fastest method to calculate substring

    - by Misha Moroshko
    I have a huge "binary" string, like: 1110 0010 1000 1111 0000 1100 1010 0111.... It's length is 0 modulo 4, and may reach 500,000. I have also a corresponding array: {14, 2, 8, 15, 0, 12, 10, 7, ...} (every number in the array corresponds to 4 bits in the string) Given this string, this array, and a number N, I need to calculate the following substring string.substr(4*N, 4), i.e.: for N=0 the result should be 1110 for N=1 the result should be 0010 I need to perform this task many many times, and my question is what would be the fastest method to calculate this substring ? One method is to calculate the substring straight forward: string.substr(4*N, 4). I'm afraid this one is not efficient for such huge strings. Another method is to use array[N].toString(2) and then wrap the result with zeros if needed. I'm not sure how fast is this. May be you have any other ideas ?

  • stop cript debug error dialogs occur in ie8 ?

    - by Haroldo
    I get this, clicking 'no' means the page displays flawlessly. it's refering to this part of jquery1.4.2.js: // Get the Nth element in the matched element set OR // Get the whole matched element set as a clean array get: function( num ) { return num == null ? // Return a 'clean' array this.toArray() : // Return just the object ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] ); }, I assume i'm calling something in the wrong context somewhere in one of my js files (which would be a real mission to find). Will standard IE8 users get this error? (i imagine ms make it pretty difficult to reinstall ie!)

  • Redirect faster with Greasemonkey

    - by Chad
    I'm using Greasemonkey to redirect certain URLs to another but I would like to redirect before the URL to be redirect loads. Currently I'm using this simple script: //==UserScript== // @name Redirect Google // @description Redirect Google to Yahoo! // @include http://*.google.com/* //==/UserScript== window.location.replace("http://www.yahoo.com") In the above, google appears for a second and then redirected to google. I want to go yahoo immediately. Is it possible, and how?

  • jQuery access each matched element from '.find' by an index

    - by GHarping
    Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  • Push html attribute to array onClick

    - by Hunkeone
    I'm trying to push number attribute of the element to the array onclick with a simple function, but array contains only empty values separated with commas. Here's html code. <button type="button" class="btn btn-success btn-lg" number="12" onclick="basket.push(this.number)">toBakset</button> <button type="button" class="btn btn-success btn-lg" number="15" onclick="basket.push(this.number)">toBakset</button> <button type="button" class="btn btn-success btn-lg" number="18" onclick="basket.push(this.number)">toBakset</button> from the start "basket" array is empty. Seems this question is so dumb but I can't find a solution :(

  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • JS DOM: Get elements by text content.

    - by hristo
    Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

  • Backbone inheritance - deep copying

    - by Ed .
    I've seen this question regarding inheritance in Backbone: Backbone.js view inheritance. Useful but doesn't answer my question. The problem I'm experiencing is this: Say I have a class Panel (model in this example); var Panel = Backbone.Model.extend({ defaults : { name : 'my-panel' } }); And then an AdvancedPanel; var AdvancedPanel = Panel.extend({ defaults : { label : 'Click to edit' } }); The following doesn't work: var advancedPanel = new AdvancedPanel(); alert(advancedPanel.get('name')); // Undefined :( JSFiddle here: http://jsfiddle.net/hWmnb/ I guess I can see that I can achieve this myself through some custom extend function that creates a deep copy of the prototype, but this seems like a common thing that people might want from Backbone inheritance, is there a standard way of doing it?

  • What are the best security measures to take for making certain directories private?

    - by Sattvic
    I have a directory on my server that I do not want Search Engines to crawl and I already set this rule in robots.txt I do want people that have logged in to be able to have access to this directory without having to enter a password or anything. I am thinking that a cookie is the best thing to put on users computers after they login, and if they have a cookie, they can access the directory. Is this possible, or is there a better way? I want people without this cookie to not have access to this directory - access for members only Any suggestions on the best design for this?

  • Prevent jQuery Tabs to bind to <ul> elements below the main <ul> element.

    - by Shiki
    Hi, I have this HTML: <div id="mytabs"> <ul id="main-tabs"> <li><a href="">Link</a></li> <li><a href="">Link</a></li> <li class="filter"> <ul id="filter-controls"> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> </ul> </li> </ul> </div> And I set it to a tabbed control: $('#mytabs').tabs(); My problem is jQuery UI also converts the <li> elements in <ul id="filter-controls"> into tabs. Is there a way to instruct jQuery UI to only set the <li> children of <ul id="main-tabs"> as the tabs? Note: I am currently in no position to change <ul id="filter-controls" into a non-ul element.

  • How to make a page print to printer just once

    - by menislici
    I have a basic html page generated through php and it prints to a printer after a link click using Ben Nadel's print plugin. However, I don't want the user to print the page again. I tried setting the 'print' link to a negative z-index using jquery after it's being clicked, but the user can refresh the page and reuse the link so it would print again. I also know that I can somehow disable the refresh feature, by modifying what F5 does, but that would't save the day since the user can refresh the page through the url bar, and I can't remove/hide, it as much as I know. It also runs on localhost so the user client and server are on the same side. Even the browser doesn't matter since I could use the one that fits this case.

  • SlickGrid V2.0 Column name/id does not follow column when dragging

    - by Brian
    I have an application (using SlickGrid) where I need to get the column name or id at any time when user clicks on a cell (this pulls up a menu specific to the data in that column/cell). Grid works fine initially but if the column is moved (drag/drop), the column name/id does not follow the drop but remains mapped to it's initial column position. Has anyone else seen this and, if so, how did you fix it? Thanks

  • How to pass an integer to create new variable name?

    - by Joe
    I have 50 svg animations named animation0, animation1, animation2 etc. and I want to load them when the integer 0 to 49 is passed to this function: function loadAnimation(value){ var whichswiffy = "animation" + value; var stage = new swiffy.Stage(document.getElementById('swiffycontainer'), whichswiffy); stage.start(); } It doesn't work at the moment, maybe it's passing 'whichswiffy' rather than 'animation10'? Any ideas?

  • Get client timezone (not GMT offset amount) in JS

    - by Rex M
    I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

  • getting the stage from a container in kineticjs

    - by seinecle
    I have this stage associated to a container: html: <div id="container"> script 1: var stageInFirstScript = new Kinetic.Stage({ container: document.getElementById('container'), width: this.SKETCH_WIDTH, height: this.SKETCH_HEIGTH }); In a second script, I need to manipulate the shapes on the stage I just created. Is it possible to retrieve stageInFirstScript with something like this? script 2: var stageInSecondScript = document.getElementById('container').RetrieveExistingStage(); //now I have retrieved stageInFirstScript //I can add shapes to it, etc.... Any help or alternative solution would be appreciated!

  • Dynamically adjust padding on an image?

    - by Cory
    What I'm basically attempting to do is dynamically change a padding value for a scrubber image based on player position data provided by an app. I have been able to leverage the provided number to dynamically increase the width of a progress overlay image and create a progress bar, but I would like a scrubber diamond at the leading edge of the progress bar. To do this, I have positioned the scrubber diamond at the same starting point as the progress overlay and would like to increase the padding on the diamond at the same rate as the width is increasing for the progress overlay, allowing them to pace each other with the scrubber diamond moving as the song plays. Any help with the script necessary to manipulate padding-left dynamically would be very much appreciated. var progress = Ecoute.playerPosition(); var width = 142.5 / length * progress + 1.63; EcouteSel('Progression').width = width.toString(); EcouteSel('Scrubber').style('padding-left', 'width'); We define progress as the player position, width as a function of the progress and then apply that function to the ID applied to the progress over lay image. But how do I accomplish that for padding-left? style.paddingLeft ...based functions have broken the controller outright. I'm at a loss and any help would be appreciated.
