I tried my best to convert JavaScript to FBJS according to this page: http://wiki.developers.facebook.com/index.php/FBJS.
Yet my tabs are still not working properly. Does anyone have any suggestions how to fix this so I can click through the tabs and display and hide content accordingly:
<script type="text/javascript"><!--
var tabLinks = [];
var contentDivs = [];
function init() {
var tabListItems = document.getElementById('tabs').getChildNodes();
for ( var i = 0; i < tabListItems.length; i++ ) {
if ( tabListItems[i].getNodeName("LI") ) {
var tabLink = getFirstChildWithTagName( tabListItems[i], 'A' );
var id = getHash( tabLink.getAttribute('href') );
tabLinks[id] = tabLink;
contentDivs[id] = document.getElementById( id );
}
}
var i = 0;
for ( var id in tabLinks ) {
tabLinks[id].addEventListener(onclick, showTab)
tabLinks[id].addEventListener(onfocus, function() { this.blur() };
if ( i == 0 ) tabLinks[id].setClassName('selected');
i++;)
}
var i = 0;
for ( var id in contentDivs ) {
if ( i != 0 ) contentDivs[id].setClassName('tabContent hide');
i++;
}
}
function showTab() {
var selectedId = getHash( this.getAttribute('href') );
for ( var id in contentDivs ) {
if ( id == selectedId ) {
tabLinks[id].setClassName('selected');
contentDivs[id].setClassName('tabContent');
} else {
tabLinks[id].setClassName('');
contentDivs[id].setClassName('tabContent hide');
}
}
return false;
}
function getFirstChildWithTagName( element, tagName ) {
for ( var i = 0; i < element.getChildNodes().length; i++ ) {
if ( element.getChildNodes[i].getNodeName(tagName) ) return element.getChildNodes[i];
}
}
function getHash( url ) {
var hashPos = url.getLastIndexOf ( '#' );
return url.getSubString( hashPos + 1 );
}
init();
--></script>
Thanks for any response.
FBML tabs (which use FBJS) are deprecated now and will be disabled in the future. You should create a new application with IFRAME tab (which is by default now).
IFRAME tabs are just tabs with IFRAME inside, and your code is loaded into this iframe from a specified URL as any other web page. You can use any Javascript frameworks in it (like jQuery), so you don't need to learn how to write FBJS.
Setup a Facebook page that uses a Facebook app. Make sure you set up your app using an iFrame that points to a file on your server. You'll get a lot more freedom using an iFrame when it comes to Javascript and it's a great way to leverage a CMS if you're going to need to do that as well. Best of Luck!

I'm making some Adobe Bridge (CS 5.1) plugins.
My problem is that I cannot figure out how to ensure that their respective menu items will be greyed out unless the user has selected valid items for the script.
I can reach the desired state by coding something like
function greyOutMenu () {
var doc = application.document;
var these = [];
these = doc.selections;
menuItem.enabled = true;
if ( these.length < 1 ) {
menuItem.enabled = false;
return;
}
for ( var i in these ) {
if ( these[i] /* is invalid */ ) { menuItem.enabled = false;
return;
}
}
but how do I get this check to run directly when the menu is opened? If I use
myMenu.onSelect = greyOutMenu();
It just runs the check on startup instead of when the menu is opened!
Okay, I figured out what was wrong. I have changed it to...
function greyOutMenu () {
var doc = app.document;
var here = doc.presentationPath;
var thisFolder = Folder ( here );
if ( decodeURI ( thisFolder.name ) === "correct folder name" ) { menuItem.enabled = true; }
else { menuItem.enabled = false; }
if (!app.document.selectionsLength > 0 ) { menuItem.enabled = false; }
}
menuItem.onDisplay = greyOutMenu;
I could have sworn that I had already tried menuItem.onDisplay, but I must have made a syntax error.
Also, In my case it is enough to be in the right folder and have something selected, as the files are added directly by a camera. More complex checks are instead added to the function itself, to prevent stuttering every time the menu is opened.
I am having issue with ckeditor4.When I run it independently its working fine.But when I trying to run it with my angular app its not working.Here is my sample code:
var initSample = ( function() {
var wysiwygareaAvailable = isWysiwygareaAvailable(),
isBBCodeBuiltIn = !!CKEDITOR.plugins.get( 'bbcode' );
return function() {
var editorElement = CKEDITOR.document.getById( 'editor' );
// :(((
if ( isBBCodeBuiltIn ) {
editorElement.setHtml(
'Hello world!\n\n' +
'I\'m an instance of [url=http://ckeditor.com]CKEditor[/url].'
);
}
// Depending on the wysiwygare plugin availability initialize classic or inline editor.
if ( wysiwygareaAvailable ) {
CKEDITOR.replace( 'editor' );
} else {
editorElement.setAttribute( 'contenteditable', 'true' );
CKEDITOR.inline( 'editor' );
// TODO we can consider displaying some info box that
// without wysiwygarea the classic editor may not work.
}
};
function isWysiwygareaAvailable() {
// If in development mode, then the wysiwygarea must be available.
// Split REV into two strings so builder does not replace it :D.
if ( CKEDITOR.revision == ( '%RE' + 'V%' ) ) {
return true;
}
return !!CKEDITOR.plugins.get( 'wysiwygarea' );
}
}
When I console after "isBBCodeBuiltIn = !!CKEDITOR.plugins.get( 'bbcode' )" line its consoling fine.But it is not entering inside return function() { }.Any suggestion?
How can I tell, in JavaScript/jQuery if a link is Javascript?
For example:
Trigger
Trying to make sure a script only logs links, and not javascript, anchors, etc.
Basically I need to capture the href of the link as I .each through them (already done) I just need a reliable way to check that variable to see if it is javascript, ie, function w/e
var rand = function() {
return Math.random().toString(36).substr(2);
};
$(function(){
$('#lhcb a').each(function() {
var rawlink = $(this).attr("href");
var link = encodeURIComponent( rawlink );
var token = rand();
var href = $(this).prop('href');
var proceed = $.get( "lhc/link.php?link=" + link + "&a=c", function( data ) {
if ( data == 1 ) {
return true;
} else {
return false;
}
});
if ( href.match("^javascript:") ) {
proceed = false;
}
if ( rawlink.charAt(0) != '#' ) {
if ( proceed ) {
$(this).after( " <span style='font-size:xx-small;'>( Hits: <span id='" + token + "'></span> )</span>" );
$.get( "lhc/link.php?link=" + link + "&a=q", function( data ) {
$('#' + token).html(data);
});
$(this).attr( "href", "lhc/link.php?link=" + link + "&a=g" );
}
}
});
});
This is what I have, but as mentioned below, it wouldn't be able to see if the href is just a function without the JavaScript declaration.
A little script can help. I wrote a sample:
http://jsfiddle.net/qXkHX/
var normalLinks = [];
$("a").each(function(i) {
var a = $(this);
var href = $.trim(a.attr("href"));
if(href.indexOf("javascript:") !== 0) normalLinks.push(href);
});
$("#result").text(normalLinks.join(","));
It iterates through the anchors in the document and pushes every link that does not start with javascript:. Maybe this helps.
I have Javascript functions called start() that have multiple functions to load using window.onload function. However, I have below function that works independently fine. However, if I write it inside the window.onload, then it doesn't work.
//START()
window.onload = start;
function start()
{
loadValues();
showState4();
}
Code that does work independently fine.
window.onload=function(){
document.getElementById("src2TargetAll").onclick = function() {
sureTransfer(document.getElementById("net"), document.getElementById("target"), true);
};
};
I tried re-writing the code as follows in window.onload but it doesn't work. How to re-write the below code in single window.onload function.
window.onload = start;
function start()
{
loadValues(); //loadValues() and showState4() works fine without sendValues().
showState4();
sendValuess(); // tested this sendValues without above two functions and that also works fine. but three functions in window.onload creates a problem
}
function sendValuess(){
document.getElementById("src2TargetAll").onclick = function() {
sureTransfer(document.getElementById("net"), document.getElementById("target"), true);
};
};
Error that I get after adding sendValues() to window.onload is as follows:

below is the code for loadValues and other functions as requested by a person who trying to help me:

var me = document.getElementById('stk1');
var values = ''; //populate selected options
for (var i=0; i<me.length; i++)
if (me.options[i].selected)
values += me.options[i].value + ',';
values = values.substring(0, values.length-1);
var selected=[values];
var temp= new Array();
temp = values.split(",");
var del = document.getElementById('StakeHolder');
for(var i=0; i<del.length; i++)
{
for(var j=0;j<temp.length;j++)
{
if(temp[j] == del.options[i].value)
{
del.options[i].selected = true;
}
}
}
}
function loadValues()
{
var RD_REQ_RT_ID = "<%=RD_REQ_RT_ID %>";
if(RD_REQ_RT_ID=="null")
{
document.getElementById('requestType').value="";
}
else{
document.getElementById('requestType').value=RD_REQ_RT_ID;

var options = target.getElementsByTagName("option");
if ( !isSelected ) {
return options.length;

How to add sendValuess() to window.onload without any issue?
window.addEventListener will not work in IE so use window.attachEvent
You can do something like this
function fun1(){
// do something
}
function fun2(){
// do something
}
var addFunctionOnWindowLoad = function(callback){
if(window.addEventListener){
window.addEventListener('load',callback,false);
}else{
window.attachEvent('onload',callback);
}
}
addFunctionOnWindowLoad(fun1);
addFunctionOnWindowLoad(fun2);
The error:

It occures when IE is running in compatibility mode. (happens while using FB and Google+)
goto "Tools" menu and select the "Compatibility View Settings" option. This will open a window where you can turn off the feature "Display all websites using Compatibility View".
So I have this function to strip out scripts from the page, but some scripts that are many lines long are still showing up. Is there a way to remove all scripts from the page that loads.
function filterData(data){
// filter all the nasties out
// no body tags
data = data.replace(/<?\/body[^>]*>/g,'');
// no linebreaks
data = data.replace(/[\r|\n]+/g,'');
// no comments
data = data.replace(/<--[\S\s]*?-->/g,'');
// no noscript blocks
data = data.replace(/<noscript[^>]*>[\S\s]*?<\/noscript>/g,'');
// no script blocks
data = data.replace(/<script[^>]*>[\S\s]*?<\/script>/g,'');
// no self closing scripts
data = data.replace(/<script.*\/>/,'');
// [... add as needed ...]
return data;
}
Here is an example of the script that comes through in the html
<script type="text/javascript">
var ccKeywords="keyword=";
if (typeof(ccauds) != 'undefined')
{
for (var cci = 0; cci < ccauds.Profile.Audiences.Audience.length; cci++)
{
if (cci > 0) ccKeywords += "&keyword="; ccKeywords += ccauds.Profile.Audiences.Audience[cci].abbr;
}
}
</script>
If I got you right, you need to remove all <script> tags with inner code from piece of HTML string. In this case you can try the following regular expression:
data.replace(/<script.*?>[\s\S]*?<\/script>/ig, "");
It should successfully work with one-liners and multi-liners, and does not affect other tags.
DEMO: http://jsfiddle.net/9jBSD/
checkout sugar.js - http://sugarjs.com/
it has a removeTags method that should do what you want
http://sugarjs.com/api/String/removeTags
function filterData(data){
var root = document.createElement("body");
root.innerHTML = data;
$(root).find("script,noscript").remove();
function removeAttrs( node ) {
$.each( node.attributes, function( index, attr ) {
if( attr.name.toLowerCase().indexOf("on") === 0 ) {
node.removeAttribute(attr.name);
}
});
}
function walk( root ) {
removeAttrs(root);
$( root.childNodes ).each( function() {
if( this.nodeType === 3 ) {
if( !$.trim( this.nodeValue ).length ) {
$(this).remove();
}
}
else if( this.nodeType === 8 ) {
$(this).remove();
}
else if( this.nodeType === 1 ) {
walk(this);
}
});
}
walk(root);
return root.innerHTML;
}
filterData("<script>alert('hello');</script></noscript></script><div onclick='alert'>hello</div>\n\n<!-- comment -->");
//"<div>hello</div>"
