Sliding Panel - Take The Object OSidebar Out Of The Global Scope

Jun 10, 2011

I created this code for a sliding panel and it works well. But I'm struggling to take the object oSidebar out of the global scope. I would prefer that it were a property of the clicked event object. That is, I want to be able to use 'this.oSidebar' within the click event. I've posted the whole page here along with the click image.

Cannot Access Global Variable Inside Object Declaration

May 9, 2011

Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).

The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;

//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}

//this function is in an interval
function moveslides() {
/* this is where I have the problem

It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...
}}}
The page is at [URL] and works on every browser, including finnicky opera, except for ie. The full code is availabe when you right click and view the source on the page.

JQuery :: Global Object Created In All IE Browsers When Aborting AJAX Requests

Oct 3, 2011

When a pending ajax request is aborted in IE browsers there is a new global object called "jQuery" + timestamp, for example "jQuery16405272192696596443".

This happens in every IE from 6 to 9 but not in Chrome, Safari, FireFox in their current stable versions. I am a bit lost and found nothing similar. I created a little test page to determine whether it started due to some own code or just in this little piece.

Example HTML:
<!DOCTYPE html>
<html>
<head>

Object.onclick=function() - Function To Be Called That Tells The Browser Where That Image Is Located In An Object

Jul 11, 2011

I am making a small gallery script. When a user clicks an image, I would like for a function to be called that tells the browser where that image is located in an object. For example:

It works, I just don't like it because it is messy and it seems sensible that some workaround exists.

JQuery :: Set Background-Image To Image Object

Jun 10, 2009

I have a LARGE, hi-resolution image that I am trying to use as the background for a page. Because it is so large, it takes a while to download. Because of this, I wanted to load the image behind-the-scenes and show it once it is downloaded.

To accomplish this, I'm using the following JQuery code:

This code clearly downloads an image and appends it to my DIV element. However, I really want to set this downloaded image to the background-image CSS property of my DIV. The reason why is because I have content inside the DIV that should serve as the foreground.

How do I dynamically download an image, fade it in, and use it as a background?

Opera And Image Object Onload

Jul 23, 2005

I can't get Opera to fire an event when an image object's src has
loaded. The test code I'm using is this -

---------------------------------
window.onload=go

function yo() {
alert("yo");
}

function go() {
//alert("go?");
var pic=new Image();
pic.onload=yo; // method 1
//pic.addEventListener("load",yo,false); // method 2
pic.src="serenity.jpg";
}
---------------------------------

Code is in a file on it's own referenced from the xhtml. Using either
of the two methods indicated the function yo doesn't get called.

Code works as expected in Firefox, Mozilla, Konqueror, IE. If I
uncomment the alert in go() I can see that go does actually get called.
Nothing comes up in Opera's Javascript console.

Getting At The Binary Data In An Image Object

Dec 8, 2005

I've search far and wide for an answer, so forgive me if this is a
stupid question. (Well, it probably is.)

Consider the following javascript:

var foo = new Image();
foo.src = "http://some.server.com/some_filename.gif";

Now, the browser will retrieve 'some_filename.gif' from some.server.com
and put it into the object foo. What I want to do is then subsequently
analyze the actual binary data contained inside some_filename.gif.
(Specifically, I just need to look at the first few bytes.) Is there
any way to do this in just JavaScript?

Get The Binary Data Of An Image Object?

Dec 19, 2009

I'm trying to get the binary data of an image object.

I've found articles to writing binary to be the source of an image, but they don't tell you how to do the reverse. Pretty much, after the page loads I want to do something like.

myImg = document.getElementById('cow.jpg');
binData = myImg.somethingToGetBinaryDataPlese

For those that are curious why I'm doing this its for another project I'm working on where I store the binary data somewhere else after load, but for technical reasons this has to be done client side for if I do it server side I'm not getting the results I need for this project.

Create Image Object From Binary Data?

Mar 2, 2009

Im trying to implement dynamic images on my site. Basically, there is a list box, and when the user selects an option, it calls a service that streams back a base64 encoded image that will be the preview of what they're looking at.in FF you can do this: img.src = "data:image/png;base64," + args ; This doesnt work for IE. from what ive learned, IE doesnt support this type of inline coding.

I was thinking that maybe the next best solution would be to convert the base64 back into binary, and set the new image object to that source. something like this:

Code:

var img = new image();
img.source = binarydata;

now obviously, img.source isnt a real method. but i would like to be ale to set the binary data as the image.

possiblities: Is there anyway to save that binary as a file on the client? and then be able to reference that file as the picture img.src = "images/" + newfilename;

Some other alternatives is to stream back a reference on the server to get the picture, this would require two callbacks, which i dont want.

Also, there is a method of turning the image into a big array of HTMl elements, and each element holds a color, being a pixel. im not doing that, that is the biggest hack job i have ever seen.

Image Object Src Not Accepting Absolute Paths?

Jul 9, 2010

My page accepts a url with various parameters passed in querystring. One of the parameter is the URL of the Image I wish to display on the page. I save this URL in a variable "imagesource"

To ensure the image is not bigger than the size permitted, I use image object to get the height and width of the image.

Now here's my code:

function foo(){
......
var imagesource = URL of the image;
....
var newImg = new Image();

Button Vs Clickable Image - 404 Object Not Found

Jun 17, 2010

I have a "button" that calls formA, which in turns calls formB, all done through javascript. As a button: <input type="button" value="Preview" onClick="popupform();"> works perfectly. Of course the user doesn't want some ugly standard button. They want this beautiful image to show instead (personally, I think the .gif they made looks like barf, but that's besides the point...sorry). When I substitute

<input type="image" src="/preview/preview_button.gif" name-"preview" alt="Preview Your Item" border="0" onClick="popupform();"> everything works as it should, except the original form, the one that has the button/image on it, becomes a 404 Object not found. The popupform() sets a bunch of cookies, and calls formB. FormB is a .php which reads the cookies and does some other stuff. Not that it should matter, but I am running everything locally in Vista using the XAMPP Apache Friends Edition and going through localhost (because formB is a .php)

Prototypes - Extending An Image Object To Make A Snowflake?

Jan 1, 2011

In the spirit of the season, I wanted to make it snow on my website. So I began digging. Eventually I ended up with a script that moved an image element down the page in a snowflake-like manner. The problem with it was it was dependant on an img element for every flake - simply no poor programming when using an Object Oriented programming language.So I decided I wanted to extend (in Java-speak; most of my programming background is in Java) the in-built Image object. The new object's src variable will lead to an image of the type of flake it is. (I want to be able to have more variance in images than a simple dot.) The new object will have a function that will allow it to move.A separate,unrelated function will control when each flakes move.

I did some more research and read about prototyping on JavaScript Kit and here (http://mckoss.com/jscript/object.htm), but I still cant seem to get this to work. JS Lint says it's bug-free, but Firefox says "move()" is an invalid function. I am presuming the problem lies in my inability to fully grasp how to extend objects in JavaScript.

Image Object Doesn't Support Filenames Using %20 To Replace Spaces?

Apr 22, 2010

The first example works as planned and has a valid .height/width value, but the second and third example using encoding/space doesn't (0 height/width). I was under the impression that replacing spaces with %20 was supported?

1:

javascript Code:

imageFile = new Image();
imageFile.src = "/somedir/somedir/image.png";
imageFile = new Image();imageFile.src = "/somedir/somedir/image.png"; 

[Code]....

I haven't been able to resolve this on my own and searching for answers on the internet has been going on for along time now. I'm simply pondered as to why that encoded format doesn't work and how to use a spaced filename.
