I tried posting the problem I had earlier, but I did not fully understand the problem and I had other issues that I confused to be part of this, so I deleted the post. Now that I solved the other problems and pinpointed the problem, here it is...
I'm trying to ajax load some elements from another page and it works in FF3.5+, Chrome 8+, Safari 3+, Opera 9.5+, and IE9.
I was trying to fix it on IE7 and found that it will only load the whole page and not just certain elements using selectors.
The code:
navigation.children('a').click(function() {
if(pageNum <= max) {
$(this)
.css({display: 'none'})
.after(loading)
.blur();
$('<div />')
.load(nextLink + ' .post', function() {
pageNum++;
nextLink = nextLink.replace(/\/page\/[0-9]?/, '/page/'+ pageNum);
if(pageNum <= max) {
navigation.children('a').css({display: 'inline'});
loading.remove();
}
else {
navigation.html('');
}
navigation.before($(this).html());
})
.ajaxComplete(function() {
if (pageNum > max) {
navigation.remove();
}
});
}
return false;
});
If I change .load(nextLink + ' .post', function() to .load(nextLink, function(), it will work in IE7, but will display all the other stuff I didn't want.
Link to the problem: http://gavsiu.com/portfolio/
are yousure nextLink is a string. Can you just cast it to a string and then try concatenating something like
String(nextString) + ".class"

I am trying to apply a solution described here: Prevent body from scrolling on mouswheel, but not the texarea to textareas which are editable by CKEditor.
I tried to add the following code to the bottom of config.js and styles.js
$( document ).ready(function() {
debugger;
$('.cke_editable')
.bind('mousewheel', function(event, delta) {
if (this.scrollHeight && this.scrollHeight <= $(this).height() + $(this).scrollTop() && delta < 0){
event.preventDefault()
} else if($(this).scrollTop()===0 && delta > 0){
event.preventDefault()
}
});
});
But the scrolling doesn't change and I think the code doesn't run at all (e.g. it doesn't break on debugger).
I've no clue about the other solution (wrapping content inside <body> tag), looks like some hacking would be necessary to apply to CKEditor.
[Edit]
After including code from the accepted answer and after further experimenting with CKEditor on my Drupal site, this is the code that finally works:
CKEDITOR.on('instanceReady', function(ev) {
var $iframe = jQuery('.cke').find('iframe');
$iframe
.bind('mousewheel', function(event, delta) {
if (this.scrollHeight && this.scrollHeight <= jQuery(this).height() + jQuery(this).scrollTop() && delta < 0){
event.preventDefault()
} else if(jQuery(this).scrollTop()===0 && delta > 0){
event.preventDefault()
}
});
});
It still has one problem, after changing edit mode to "Source" and then back to wysiwyg, the binding is lost. It probably needs re-binding on yet another CKEditor event. I tried CKEDITOR.on('mode', function(ev) {... following this post, but it didn't fire. If I find a solution I'll update.
By the way, here is my CKEditor fiddle with this problem: http://jsfiddle.net/67v3rwfo/
[Edit 2]
I noticed that the fiddle works only in Chrome. In Firefox and IE it scrolls the window anyway, even without changing to "Source".
Are you sure that .cke_editable exists during the document ready event? I'm guessing that even though CKE init is quite fast they only appear after .ready. Try something like this
CKEDITOR.on('instanceReady', function(ev) {
alert("InstanceReady");
// $('.cke_editable')... here
});
$(document).ready(function() {
alert(1);
});
Using alert makes sure that the code does get hit, even if the debugger is somehow derping out on you. If you never see the alert(1); it is very likely that some javascript is actually broken, because that code is unrelated to CKEditor. Check your Developer console for messages during page loading.
Edit 10.9.2014
Not sure if this helps with the underlying issue, but to target the .cke_editable element(s) in an iframe, this seems to work:
var iframeDocument = $('.cke').find('iframe').contents();
var editable = $(iframeDocument).find('.cke_editable');
// editable is like [<body contenteditable="true" …>…</body>]
I've successfully implemented a bit of code that strips all HTML from a pasted string using stripTags(). My next goal is to mark a few tags with white flags so they get ignored on 'paste' event using .wrap() to augment the function.
I'm using prototype.js as a framework and have slowly been working through the growing pains of learning both the framework and javascript, but this issue has presented a bit of a roadblock.
I've googled around a bit and found what looks like two great solutions, but I don't seem to be implementing them correctly.
Found solutions:
http://perfectionkills.com/wrap-it-up/ (function to indicate tags to remove)
and
http://pastebin.com/xbymCFi9 (function to allow tags to keep)
I pretty much copied and pasted from the latter.
If I pull the 'br' from the code, then the regex is ignored and all html is stripped. If I leave it, nothing gets pasted.
Here is what I've pieced together (and I feel silly for not being able to figure this out!).
String.prototype.stripTags = String.prototype.stripTags.wrap(
function(proceed, allowTags) {
if (allowTags) {
if (Object.isString(allowTags)) allowTags = $w(allowTags)
this.gsub(/(<\/?\s*)([^\s>]+)(\s[^>]*)?>/, function(match) {
if (allowTags.include(match[2].toLowerCase()))
return match[1] + match[2] + match[3] + '>'
})
} else {
// proceed using the original function
return proceed();
}
});
WysiHat.Commands.promptLinkSelection = function() {
if (this.linkSelected()) {
if (confirm("Remove link?"))
this.unlinkSelection();
} else {
var value = prompt("Enter a URL", "http://www.alltrips.com/");
if (value)
this.linkSelection(value);
}
}
document.on("dom:loaded", function() {
var editor = WysiHat.Editor.attach('event_desc');
var toolbar = new WysiHat.Toolbar(editor);
editor.observe("paste", function(event) {
var el = $(this);
setTimeout(function() {
var pText = el.innerHTML.stripTags('br');
//alert(pText);
$('event_desc_editor').update(pText);
$('event_desc').setValue(pText);
}, 0);
});
(You may recognize the WysiHat code from 37Signals text editor)
note: you can see the alert commented out. If I do alert the ptext, I get 'undefined' returned.
So I've given up on and moved to a regex solution:
el.innerHTML.replace(/<(?!\s*\/?\s*p\b)[^>]*>/gi,'')

I am dynamically resizing images bigger than the browser to equal the size of the browser.
This was no easy feat as we had to wait for the images to load first in order to check first if the image was bigger than the window.
We got to this stage (which works):
var maxxxHeight = $(window).height();
$(".theImage").children('img').each(function() {
$(this).load( function() { // only if images can be loaded dynamically
handleImageLoad(this);
});
handleImageLoad(this);
});
function handleImageLoad(img)
{
var $img = $(img), // declare local and cache jQuery for the argument
myHeight = $img.height();
if ( myHeight > maxxxHeight ){
$img.height(maxxxHeight);
$img.next().text("Browser " + maxxxHeight + " image height " + myHeight);
};
}
The thing is, the page is an infinite scroll (I'm using this)
I know that you are not able to attach 'live' to 'each' as 'live' deals with events, and 'each' is not an event.
I've looked at things like the livequery plugin and using the ajaxComplete function.
With livequery i changed
$(".theImage").children('img').each(function() {
to
$(".theImage").children('img').livequery(function(){
But that didnt work.
ajaxComplete seemed to do nothing so i'm guessing the inifinte scroll i'm using is not ajax based. (surely it is though?)
Thanks
Use delegate:
$(".theImage").delegate('img', function() {
$(this).load( function() { // only if images can be loaded dynamically
handleImageLoad(this);
});
handleImageLoad(this);
});
The problem is that your infinite scroll plugin does not provide the callback functionality. Once your pictures are loaded there is no way to affect them.
I have tried to modify your plugin, so that it will serve your needs, please see http://jsfiddle.net/R8yLZ/
Scroll down the JS section till you see a bunch of comments.
This looks really complicated, and I probably don't get it at all, but I'll try anyway :-)
$("img", ".theImage").bind("load", function() {
var winH = $(window).height();
var imgH = $(this).height();
if (winH < imgH) {
$(this).height(winH);
$(this).next().text("Browser " + winH + " image height " + imgH);
}
});
I can run this code in Android app (using PhoneGap adn jQuery Mobile) but not on desktop browsers.
It gives me a syntax error in firebug for this line =
var TicketList = eval("(" + ajax.responseText + ")");
Here is the code
// JScript source code
// ran on body load
function doJsStuff()
{
var ajax = AJAX();
ajax.onreadystatechange = function () {
if (ajax.readyState == 4) {
var TicketList = eval("(" + ajax.responseText + ")");
if (TicketList.ListCount > 0) {
document.getElementById("opencount").innerHTML = TicketList.ListCount +" Open Tickets";
for (Ticket in TicketList.Tickets) {
// add stuff to DOM
//AddTicketToList(TicketList.Tickets[Ticket]);
}
}
else {
document.getElementById("opencount").innerHTML = "All Tickets Reviewed";
DisplayNoresults();
}
}
}
ajax.open("GET", "http://website.com/ListTicketsRequest.ashx?PageNumber=1&PageSize=1&Status=Open", true);
ajax.send(null);
//document.addEventListener("deviceready", onDeviceReady, false);
//event to check for PhoneGap
//$('ul').listview('refresh');
$('#mtickets').page();
//showVars();
}
function AJAX()
{
var xmlHttp;
try
{
xmlHttp = new XMLHttpRequest();
}
catch (e)
{
}
return xmlHttp;
}
**TicketList is a variable in the JSon that comes across like this=
{"Tickets" : [{"TicketID": "1054","Category": "N/A","SubmittedUserID": "bob.thebuilder","ShortDescription": "test question QID:16668","CreationDate": "2/16/2011 12:24:19 PM","TicketStatus": "Open","LongDescription": "Something is wrong with this question I know I hve the right answer but it keeps telling me I'm wrong"},{"TicketID": "1053","Category": "Mission Support","SubmittedUserID": "dave","ShortDescription": "Make courseware revisions","CreationDate": "2/16/2011 9:34:48 AM","TicketStatus": "Open","LongDescription": "Find help tickets generated by users for possible courseware update."}], "PageCount": "6", "ListCount": "11"}
Note about PhoneGap If you are trying to include phoengap functions in a place where the code may also be executed on in a browser make sure you only add the phone gap function with on "deviceready" or your browser will not render. Example:
function onload(){
//event to check for PhoneGap
document.addEventListener("deviceready", onDeviceReady, true);
}
...
function onDeviceReady()
{
// Now PhoneGap API ready
vibrate(90); // vib to ack pg ready
$("a").click(function(event){
vibrate(30); // add 30 sec vib to all links
});
}
My immediate response would be to use jQuery's getJSON method, since you're aready using jQuery. jQuery's AJAX provides a much broader base of browser compatibility. Also, every time you use eval(), a small baby somewhere cries.
var url = "http://website.com/ListTicketsRequest.ashx?PageNumber=1&PageSize=1&Status=Open";
$.getJSON(url ,function(TicketList){
if (TicketList.ListCount > 0) {
$("#opencount").html(TicketList.ListCount +" Open Tickets");
for (Ticket in TicketList.Tickets) {
...
}
} else {
$("#opencount").html("All Tickets Reviewed");
DisplayNoresults();
}
});
If this still doesn't work for you, ensure that the JSON being returned is valid. But please stick to this method, and don't use eval!!
SIMPLIFIED UPDATE
var url = "http://website.com/ListTicketsRequest.ashx?PageNumber=1&PageSize=1&Status=Open";
$.getJSON(url ,function(AnyNameYouWant){
alert(AnyNameYouWant.ListCount + " Open Tickets");
});
UPDATE USING 'DATA'
If your url becomes too long, you might begin to encounter problems. It is suggested to pass the url data via the data argument.
var url = "http://website.com/ListTicketsRequest.ashx";
var data = "PageNumber=1&PageSize=1&Status=Open";
$.getJSON(url, data, function(AnyNameYouWant){
alert(AnyNameYouWant.ListCount + " Open Tickets");
});
Looking at your code, it seems likely to me that the syntax error isn't in the code you posted, but instead is contained in the JSON object you're evaluating in ajax.responseText. Take a look at the data being returned by the AJAX request. Is it valid Javascript? Does the page you're calling return something different to desktop browsers vs mobile? Is there an error message where the JSON code should be?
Another possibility: Is your app running on website.com? If not, Firefox is probably blocking the XMLHttpRequest from functioning properly. Firefox 3 and below block cross-site AJAX requests. Firefox 3.5 seems to allow some exceptions.
I have an old site that uses xml documents, and when I created it i had firefox and IE7 to test on, and it worked just great. Since then, IE8 appeared, and it seams that the site does no longer work properly.
This is the current code:
if (window.XMLHttpRequest)
{
XMLHttpRequestObject = new XMLHttpRequest();
XMLHttpRequestObject.overrideMimeType("text/xml");
XMLHttpRequestObject.open("GET", "produse.xml", true);
XMLHttpRequestObject.onreadystatechange = function()
{
if (XMLHttpRequestObject.readyState == 4)
{
xmlDocument = XMLHttpRequestObject.responseXML;
removeWhitespace(xmlDocument);
}
}
XMLHttpRequestObject.send(null);
}
else if (window.ActiveXObject)
{
xmlDocument= new ActiveXObject("Microsoft.XMLDOM");
xmlDocument.async=false;
if (xmlDocument .readyState == 4)
{
xmlDocument.load("produse.xml");
}
}
But I get this error:
Message: Object doesn't support this property or method
Line: 19
Char: 3
Code: 0
which relates to:
XMLHttpRequestObject.overrideMimeType("text/xml");
What should I use instead?
This page shows what the differences are between firefox/ie/ie8 are and has some examples of how to do it:
http://www.javascriptkit.com/jsref/ajax.shtml
Mostly it says that IE8 does not support this method and you have to make sure your server is adding the proper header (text/xml) to the outgoing response.
It also has a link to http://www.javascriptkit.com/dhtmltutors/ajaxgetpost3.shtml that explains the common pitfalls and IE problems.
It says do:
if (mygetrequest.overrideMimeType)
mygetrequest.overrideMimeType('text/xml')
jQuery would be my choice. It is a lot faster and is cross browser supported and on a CDN.
You could strip that code down to just a few lines.
$.get('ajax/test.html', function(data) {
$('.result').html(data);
alert('Load was performed.');
});
