  • Javascript permission denied - different port

    - by Grnbeagle
    Hi, I have a rails app running on port 3000. The page in question has an iframe and I need to resize it depending on the height of the content loaded in the iframe. <iframe id="ifrm_col3" name="ifrm_col3" frameborder="0" src="<%=invite_path(@invite.alias)%>" onload="util.resize_iframe('ifrm_col3');"></iframe> The resize function is here: util.resize_iframe = function(frame_id) { var h = document.getElementById(frame_id).contentWindow.document.body.scrollHeight; document.getElementById(frame_id).height = h; } After the iframe loads, I see this error in FireBug: Error: Permission denied for <http://192.168.0.157> to get property Window.document from <http://192.168.0.157:3000>. Source File: http://192.168.0.157:3000/javascripts/application.js?1268327481 Line: 84 The src of iframe is a relative path, but I'm not sure why the port info from the parent page is not retained. Is there any workaround to this problem? I tried creating a function in the parent page and calling it from the iframe, but ran into the same issue. Due to extra features in the site, I need to stick to port 3000 for the rails app. Any suggestion is appreciated.

  • javascript filter array of objects

    - by user441521
    I have an array of objects and I'm wondering the best way to search it. Given the below example how can I search for name = "Joe" and age < 30? Is there anything jQuery can help with or do I have to brute force this search myself? var names = new Array(); var object = { name : "Joe", age:20, email: "[email protected]"}; names.push(object); object = { name : "Mike", age:50, email: "[email protected]"}; names.push(object); object = { name : "Joe", age:45, email: "[email protected]"}; names.push(object);

  • Refactoring a javascript array rotate function

    - by ideotop
    I wrote a rotate function, but I'm not satisfied with it: var pixels=['011','110','000']; var result=new Array(); result=['000','000','000']; for ( y=0; y<(pixels.length); y++ ){ for ( x=0; x<(pixels.length); x++ ){ var newx=0,newy=0; if ( clock ){ if ( x< r.x && y< r.y ) {newx=x+2;newy=y ;}//top left if ( x==r.x && y< r.y ) {newx=x+1;newy=y+1;}//top if ( x> r.x && y< r.y ) {newx=x ;newy=y+2;}//top right if ( x< r.x && y==r.y ) {newx=x+1;newy=y-1;}//left if ( x==r.x && y==r.y ) {newx=x ;newy=y ;}//center if ( x> r.x && y==r.y ) {newx=x-1;newy=y+1;}//right if ( x< r.x && y> r.y ) {newx=x ;newy=y-2;}//bottom left if ( x==r.x && y> r.y ) {newx=x-1;newy=y-1;}//bottom if ( x> r.x && y> r.y ) {newx=x-2;newy=y ;}//bottom right } else { if ( x< r.x && y< r.y ) {newx=x ;newy=y+2;}//top left if ( x==r.x && y< r.y ) {newx=x-1;newy=y+1;}//top if ( x> r.x && y< r.y ) {newx=x-2;newy=y ;}//top right if ( x< r.x && y==r.y ) {newx=x+1;newy=y+1;}//left if ( x==r.x && y==r.y ) {newx=x ;newy=y ;}//center if ( x> r.x && y==r.y ) {newx=x-1;newy=y-1;}//right if ( x< r.x && y> r.y ) {newx=x+2;newy=y ;}//bottom left if ( x==r.x && y> r.y ) {newx=x+1;newy=y-1;}//bottom if ( x> r.x && y> r.y ) {newx=x ;newy=y-2;}//bottom right } //inject(result,newx,newy,pixels[y][x]) } } does someone now how to write a cleaner code for this rotate (clock and counter-clock) function ?

  • bind event handler on keydown listen function JavaScript jQuery

    - by user1644123
    I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element. My syntax may be the wrong approach, but it works for the 1st condition, but not the 2nd. I think I have the conditional statement in the wrong place. How can I rewrite this to work as intended? Thank you kindly, in advance! $(document).keydown(function(e) { switch (e.which) { case 37: break; case 38: break; case 39: break; case 40: //bottom arrow key var hits = 0; if (hits % 2 !== 0) { $('#wrap').animate({ scrollTop: $("#scrollToHere").offset().top }, 2800); } else { $('#wrap').animate({ scrollTop: $("#scroll2ToHere").offset().top }, 2800); } hits++; return false; break; } })? *I moved "var hits = 0;" to the top, but it only works! But is there a way I can reset the whole thing after every two hits? I want to reset because when there is a bug and if I press a 3rd time it scrolls to the very top of the page, where there is no element to make it scroll to the top. Why would it scroll to the top of the page if I never scripted it to do so?? *

  • DOM and Javascript

    - by Bob Smith
    I let a user reconfigure the location of a set of rows in a table by giving them ability to move them up and down. The changes are done by swapping nodes in the DOM. After the user has moved rows around, when I do a view source, I see the HTML in the original state (before the user made any changes). Can someone explain why that is? My understanding was when we do any DOM operations, the underlying HTML will be changed as well. EDIT: Does that mean on the server side, when attempt to get the state after user's changes, I will be able to get what I need? I am using C#/ASP.NET. Could it be because this is a HTML table (not ASP.NET Server control), that it's not maintaining the state of the changes?

  • sort outer array based on values in inner array, javascript

    - by ptrn
    I have an array with arrays in it, where I want to sort the outer arrays based on values in a specific column in the inner. I bet that sounded more than a bit confusing, so I'll skip straight to an example. Initial data: var data = [ [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ], [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ] ]; Sort data, based on column with index 1 data.sortFuncOfSomeKind(1); where the object then would look like this; var data = [ [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ], [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ] ]; Sort data, based on column with index 2 data.sortFuncOfSomeKind(2); where the object then would look like this; var data = [ [ "row_m-col1", "3-row_m-col2", "a-row_m-coln" ], [ "row_2-col1", "1-row_2-col2", "b-row_2-coln" ], [ "row_1-col1", "2-row_1-col2", "c-row_1-coln" ] ]; The big Q Is there an existing solution to this that you know of, or would I have to write one myself? If so, which would be the easiest sort algorithm to use? QuickSort? _L

  • Rails: Internationalization of Javascript Strings?

    - by Matt Rogish
    So, we have an existing Rails 2.3.5 app that does not support Internationalization at all. Now, I'm well familiar with Rails I8n stuff, but we have a LOT of output strings inside /javascripts/. I'm not a huge fan of this approach, but unfortunately it is too late to fix it now. How might we internationalize strings stored in JS files in a Rails app? Rails doesn't even serve the JS files... I'm thinking I could always have the Rails app serve up the JS files, but that seems pretty gross. Are there plugins to do this? Yikes.

  • JavaScript setInterval loop not holding variable

    - by Ryan
    Here is my code: var showNo = 1; window.setInterval(function() { console.log(showNo); if(showNo === 1) { var nextNo = 2; } else if(showNo === 2) { var nextNo = 3; } else if(showNo === 3) { var nextNo = 4; } else if(showNo === 4) { var nextNo = 5; } else if(showNo === 5) { var nextNo = 1; } else { var showNo = 1; var nextNo = 2; } var showNo = nextNo; }, 500); My question is, why is the showNo variable not holding when the setInterval loop starts? The console displays 'undefined' in the above example. This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.

  • How to REALLY focus a link using jQuery / javascript

    - by Bobby Jack
    Calling the jQuery focus() method on a link appears to only partially focus the link. Whilst the link has focus to the extent that pressing ENTER follows the link, it doesn't take on the default outline styling (or adopt any styling set via the :focus pseudo-class), nor is the tab-order correctly 'entered'. Any ideas on how to resolve this? (results observed in Firefox 3.6.2)

  • getting an error on jslint while creating a new object using javascript

    - by user3712689
    For some reason this code is giving a lint. I can't really figure out why. It says: 'was expecting a assignment or function call, and instead saw an expression.' What does that mean? window.onload = function (){ function SuspectOne (naam, leeftijd, wie){ this.naam = Spencer Hawes; this.leeftijd = 22; this.wie = zoon van de man; } function SuspectTwo (naam, leeftijd, wie){ this.naam = Tyrone Biggums; this.leeftijd = 28; this.wie = lokale herionejunk; } function SuspectThree (naam, leeftijd, wie){ this.naam = Ellie Campbell Hawes; this.leeftijd = 40; this.wie = vrouw van de man; } var verdachten = new Array[]; verdachten[0] = new Verdachte("Spencer Hawes", 22, "zoon van de man"); verdachten[1] = new Verdachte("Tyrone Biggums", 28, "lokale herionejunk"); verdachten[2] = new Verdachte("Ellie Spencer Hawes", 40, "vrouw van de man"); for(x=0; x<verdachten.length; x++){ console.log("De verdachte is de " + verdachten[x].leeftijd + "jaar oud " + verdachten[x].naam + ", de " + verdachten[x].wie); } }; Can someone help me with this? I would really like a lint free code.

  • JavaScript Exception/Error Handling Not Working

    - by Seán Hayes
    This might be a little hard to follow. I've got a function inside an object: f_openFRHandler: function(input) { console.debug('f_openFRHandler'); try{ //throw 'foo'; DragDrop.FileChanged(input); //foxyface.window.close(); } catch(e){ console.error(e); jQuery('#foxyface_open_errors').append('<div>Max local storage limit reached, unable to store new images in your browser. Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?
