I have a drop down box (select) in my website: [URL] that works fine; but the problems is if the user click on a wrong option, it will show a box and if the user click on another option from the box, the last one will be on display and won't go off..
Like this select something and then at the same box change the selection you will see the code will build up boxes on the screen.. How I do for it not happens if the user change the option in the last box, the one before disappears!
I am creating dynamic questions and question's choices (radiobuttons or checkboxes) from database when runtime..after users answer the question, press next button to pass the next questions
For example
1) Question definition
a)choice definition
b)choice definition
c)....
Users have to choose any choices..if not, my system is giving alert, Actually my problem is about checkboxes. I created hidden textboxes, if question choices' type is checkbox. So the last choice definition is name "Other". If user checks the other choice, the hidden textbox is going to be visible. It is all okay until here. I want to give a error alert if user checks the other choice and doesn't fill the textbox when press next question. I don't validate this. How can i do it.
I tried the script below in IE 6, 7, and 8 and it all seems to work, but it doesn't work with firefox 3. I'm trying to do a preview to an upload image, pretty much like how kijiji does it. (try it with kijiji if you want to know what I mean).This script shows a thumbnail of the image that is about to be uploaded before the form is submitted.Anybody know how to make this work in all browsers?

View 1 Replies View RelatedI'm using image as a resizing grip for my element and under IE and Opera it works fine but in Firefox it starts dragging the image when you press mouse button and move mouse and doesn't generate mousemove events. Is there a way to prevent the image from being dragged?

View 1 Replies View RelatedI am building a site in Dreamweaver for a client which uses templates
for a photogallery that uses simple Javascript to load images "OnClick"
into a named <img> tag. The <img> tag has no dimensions preset because
the loaded images vary in size and aspect ratio (the images
are all prepared so that they will fit easily within the rest of the page
layout, using their actual dimensions).
This all works just fine on Firefox (Apple), but on Safari and Mac IE
there is a problem. When image-2 replaces image-1 (using MM_swapimage),
if image-2 has the same height but a narrower width than image-1, then
image-2 appears with image-1's width. Both image-2 and image-1 have
the same height, so the display of image-2 now has the wrong aspect
ratio (everthing looks "fatter").
I haven't checked Windows browsers yet. I searched around and
haven't seen a similar issue. Anyone know about this, and a good workaround?
I want to have a big image and say 5 small thumbnails underneath. When the user clicks a thumbnail, the image loads where the previous big image was. Is there a standard way to do this?

I'm writing a class that will enable the user to upload files to
the server without reloading the current page (using target="iframe"),
and it works just fine in Firefox, but when I test it in IE, first of
all, the iframe is not targetted at all, and IE stupidly opens a new
window, second the <input type="file" element looses it's name
attribute for some reason... I tried using DOM and assigning the
element thru innerHTML, both will just not work in IE (and will just
fine in Firefox). Those interested to have the source code (commented
in french) may just ask me. But if anyone had similar problems, and
would want to share with me, I'd really much appreciate, because this
is driving me insane!
In short, how can I make this javascript to refresh the page when uploading is done ?
function $m(theVar){
return document.getElementById(theVar)
}

I have heard that there is a java script that enables clients to upload files through the browser from a page on my site. I have tried CGI and Perl but my server wont allow them.
View 1 Replies View RelatedI'm writing script using AJAX and PHP to upload files. I'm trying to
create progress bar to show how many bytes have been already uploaded to
server.
Can I get the total file size (using JS) before sending it to server or
immediately after start sending it?
And how to obtain amount o bytes that have been already transfered to
server using JS? I know how to do it in PHP (XMLHttpRequest to php file
that counts temporary file size), but is it possible in JS?
Is there a way I can use JavaScript to compile a list of checkboxes with the value of the url of the file I wish to upload from my computer.And then with that checklist PHP can grab the files from my computer and upload them to the server. Doesn't have the be checkboxes but basically a list of locations so the files can be uploaded one after another. Much like Facebook's ability to upload multiple files. I can't find out how to select multiple files, so I figured just compile a list.

I am trying to write a multifile upload script in JavaScript. Before the upload, my HTML looks like this:
<input type="file" id="file_0">
<input type="file" id="file_1">
<input type="file" id="file_2">[code]......
But, how do I upload multiple files in "all versions" of Firefox and "all versions" of IE?
Right now I am using the javascript 'prompt' to enter a photoid and the
script that I am using uses document.write
to put the proper image on the page ....i.e. PHOTOID =".jpg"
What I want is a simple user input text area and when submit is clicked a
placeholder image beneath is exchanged for the proper
image based on the user's input.
example: User enters re4555 and the image re4555.jpg replaces the image
nosel.jpg
that I have created which basically says 'no image selected'.
I am trying to pop-up a window when the user clicks on an image. The problem is that when the user clicks on the image and the window pops up OK, but the window underneath also proceeds to the image. The desired behavior is that when the pop-up is invoked, I want the
underlying window to stay put. Code:
I want to give the user possibility to paste an image into a webform. I don't need to display the image, all I need is the image's location.I know it's possible because the guys at CKEditor(and other editors) are doing it. If you go here, [URL] and paste an image you copied and then right click on it and go to image properties you'll see they have the image's address. How can this be done?
