I'm pretty rubbish at java and I'm trying to get an image to change when a user clicks a link. I don't know why this doesn't work.
foc.src=foc.src==Ƈ.gif'?ƈ.gif':Ƈ.gif'
foc is the image element - if i do foc.src=ƈ.gif' it will quite happily change but I want it to alternate between the two images every time the link is clicked.
When using javascript [1] to display a different image (based on the
time of day) both IE and Moz re-execute the js when using the back
function to return to a page with the js on it, this results in users
having to load several images. Opera doesn't do this.
Is there a right or wrong regarding this UA behaviour?
Has anyone seen a javascript image editor of any sort?
I can imagine one that allows you to load up an existing image - draw lines, place text, fill etc using something like XMLHttpRequest to work. It would be like a java image editor but lighter. It would then let you save the new drawing.
I've tried looking round but not found much except a business card designer which allows you to type text at predefined locations.
Can someone help me with a javascript code to validate an image URL?
I want to validate the following:
1. the URL must start with http://
2. the URL must end with .gif, .jpg, .jpeg or .png
I'm I leaving out something?
i am in need of an image dropdown to enable users to visually select images from a dropdown and see the image preview in the actual dropdown itself. Code:
this does not seem to work as my icons are 64 x 64 pixels and therefore i cannot figure out how to customise this.
I have this...
<div id="mainframe">
<img src="image.jpg" id="image">
</div>
Then when I try to in a function say...
function checkImage()
{
var image = document.getElementById("image");
var height = image.height;
}
Many times the image height will not be defined.
I recently changed the past so it uses AJAX to change the <img src...
stuff to return new data for that inner HTML block..
Still the image will not have properties.
Now, this is a problem in IE/FF, but not in opera.
Any ideas on how to make sure the image is loaded so its height/width
properties are available... either by swapping the image.src or by
using ajax to swap out the div innerHTML??
I am trying to include some javascript in my website which rotates some
stored images. I have attached the code for the index page of my
website as i am having some problems getting it to work. Can anyone see
where i am going wrong? This is my first attempt.
Here is the source script:
I have a <img scr="mypic.jpg"in my html. I would like to display the
image by width=200 if the image width is larger than 200. I also would
like to display the image by its real width if the image width is
smaller than 200. How can I do it?
I'd like to flip horizontally an image with JavaScript. Is it possible?
View 6 Replies View RelatedI have some CSS/javascript which takes an image and re-sizes it on a page with a hover-over state which causes it to expand. However, this will only re-size to specific proportions (in this case 1:1).
This is fine in the case of e.g. an 86x86 image but what I want to be able to do is detect if the image has a height greater than it's width, and if so, crop the image accordingly to make it a square.
Is there a way of doing this with javascript?
How do I create an email link using javascript attached to an image link?
The simpler methods I have so far been able to find only work within form elements.
I have also tried...
window.location="mailto:contact@mydomain.com"
parent.location="mailto:contact@mydomain.com"
location.href="mailto:contact@mydomain.com"
... none of which seem to work.
What's the secret? Where am I going wrong?
I've got a site with a ton of javascript image galleries, the kind where:
(1) there is a set of images associated with a single page,
(2) the urls for all the images of the set are in the javascript code on the single page.
(3) When you hit "next" on the image gallery navigation bar, it uses the next image url in the javascript and makes the next image appear.
Problem: All the image views are on 1 page. Somebody can view 100 images and it would count as one pageview ie one banner impression.
I started this when I had little traffic but now traffic is ramping and it's costing me to be losing these banner impressions.
Is there a javascript solution to this problem? Perhaps somehow generating the "next" image on a new javascript-generated page (but one with all the same left/top/bottom includes)?
I'm imagining the functionality to the user would be the exact same as the current system. The only difference is instead of only loading a new image only, an entire new page is loaded. The new page would have a unique name (ie page1, page2, page3 ,etc). It could not be a meta-refresh, I don't want to be accused of meta-refreshing banner impressions.
I'd like to see and use a javascript to resize an image.
I've creating a site and I'd like that only this image will be resizable automatically based on resolutions (800x600, 1024x768, 1280x1024, ecc...)...
We've got a server-side page (status.php) that dynamically generates a GIF image. The displayed image depends on the value of a boolean field in a database. Just calling the page displays the current value of the boolean, calling it with a parameter switch (status.php?switch) flips the database value and generates a new image. We've included headers to prevent caching of the image by the browser.
Whenever our HTML page is displayed in the browser, we just include an image that shows the current status: img src='status.php'/
We want to allow the user to click the image, which then inverts the boolean status in the database: img src='status.php' onclick='this.src=status.php?switch;'/
This works great in Internet Explorer, but both Mozilla and Opera only allow to switch once. My idea of the problem is that those browsers think like this; after one click, the src is already 'status.php?switch', so changing the src again would be redundent in their eyes, so they won't do it.
We found a temporary solution by generating the current time as a parameter in the image URL: img src='status.php' onclick='this.src=status.php?switch+(new Date());'/
However, this is not a very elegant solution.
Does anyone know a proper solution to this? This means, forcing Mozilla and Opera to load an image using JavaScript, even though the URL of the image didn't change?
I am using a simple javascript image insertion on my XHTML page, and I have encountered a problem. The Javascript code fails to execute when the doctype is XHTML on Firefox (works on Opera). However, when I simply rename the file with an HTML extension, the code executes on all browsers. Code:

View 1 Replies View RelatedI'm trying to be tricky and its not been working LOL. I have a gallery page with lots of thumbnails that load up. What I wanted to do was have a "LOADING IMAGE" GIF in each of the table cells so that the user would see visually how many more images were going to load up. That bit is fine but when all the thumbs have loaded I want to change that Cell background image to something else.
How would I do this? Would I be able to reference them all at once or would I have to reference each individual cell one at a time.

View 18 Replies View RelatedCan anyone assist me with what I am trying to do with the following
code (six different scenarios to try to make the functionality work
correctly)?
I want to always (and ONLY) display in the status bar 'Symantec
Corporation' whenever anyone mouses over (onMouseOver) my image or
link OR when one clicks while holding the left mouse down (onClick) on
the same image or link. Upon releasing the mouse (onMouseOut), the
status bar should be 'blank'. I need the link to open in a new window
via my function openWindow(URL) code.
What is happening in most of the six scenarios, is that when one
clicks the link, either the function doesn't engage, but rather the <a
href= takes effect instead OR that status bar shows
'javascript:openWindow('http://www.symantec.com/');' when one clicks
while holding the left mouse down (onClick) on the image or link.
Additionally, for only the link, I need the CSS/style to show 'red'
when one mouses over (onMouseOver) it and then change to 'blue' upon
releasing the mouse (onMouseOut).
How about integrating 'style="cursor:hand"' into the code or perhaps
setting some of the data via a <div> or <span> snippet? Code:
i'm wanting users to be able to upload an image, but i want the image to be a specific aspect ratio. if you've uploaded a contact picture for your gmail account - you know what i'm talking about. here's a screenshot of the cropping ability in gmail...
i'm assuming the crop lines are somehow determined via javascript and those numbers are passed to something similar to the GD Image Library in PHP where you can crop images.

View 1 Replies View RelatedIm trying to have a click event that replaces an image on the page with a new image that has been selected randomly from an array. I have solved PART of this already (can get the random image to appear).
However, instead of appearing on the page where the old image was, the new image appears in a blank page.
My research indicates that this blank page location-problem is a result of using document.write in the Function. Therefore, I know I need to find a different way to accomplish this, but am failing miserably.
I have been trying for hours and hours and HOURS to figure out proper syntax for accomplishing this via elements, functions, variables and mootools.

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"

</head>
<body>

<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>

showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.
Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:
two possibilities or the attribute type of script:
text/javascript (the one i usually use) application/x-javascript
what are the differencies between both?
depends on the html content?
for example html 4.0.1 versus xhtml 1.1?
