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?
this works in chrome and safari, but not opera, ie or ff? grr!http://tigerbaydesign.co.uk/imagech.htmli'm thinking it's tied up with getting the backgroundImage first because i know all browsers are getting inside the action braces..you can view source or look at this:
HTML Code: <title>image change test</title> <link href="imagech.css" rel="stylesheet" type="text/css" />
I'm relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>.The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed.
I am no very little when it comes to Javascript but I have seen a few sites using pre populated text boxes for login forms. So Username and password appears in the boxes to save space. The code below works fine onload of the site in all browsers, everything also works fine in firefox but ie the following doesn't seem to work.When a user clicks to enter their password in i.e. it doesn't change the form to password characters so input plain text. Also when you click out of either box it doesn't seem to re-populate the boxes with my Username or Password text.
<script> function HideLabel(txtField){ if(txtField.name=='myusername'){
on my site, I have added Style 1 and Style 2 in my menu at the top righthttp://www.thisisworthing.com/default.php#when I click on Theme 2, it doesn't work?!I have this working on my other site: http://www.mypubspace.com
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.
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.
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.
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.
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 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.
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.
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:
I'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.
To better illustrate my point see this this link :
I am looking for a javascript code for this idea under this messageI want to create a kind of shopping website so when you click on a image or text it will add some text to a textarea,, it will include the name of item and price of an item
Can 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.
