I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).
View 1 Repliesis there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.

The mounds of RegExp data will take me days to sift through can someone help me create a regular expression to find a file extension? (all characters after a period) I have already gotten this far: .+. to find everything before and including the period; and I was hoping to integrate the caret to say everything but .+. But I just can't get it to work.
Note: I will be writing a file to the server with JScript ASP. The file name will be passed to the script that writes the file, and I want to make sure that in addition to removing any possible code from the line being written, that I also prevent an executable file from being created. I will be searching for certain extensions and returning if anything else is found.

I have a site with a news pages and I'd like the navigation to include a
blinking 'NEW!' when that page has been updated within the last three days.
It works fine for the one page (if you're on the news page, it works great)
but I can't figure out how to check the time/date stamp on a file other
than the one currently loaded ...
So I'm trying to create a custom file uploader which will display the name of the file selected, but since I can't seem to figure out how to do this I've settled for checking to see if a file has been selected, but I'm still having trouble with it.Here's what I have...
<style>
#upload {
display: inline-block;
text-align: center;
[code]....
However the value doesn't change after the file has been selected. Could someone tell me a means of modifying this so that it will properly display once the file has been uploaded? Do I need to have some sort of constant refresh on the Javascript to check to see if the value has been changed?
I got a file upload form (in asp), besides of checking if the extension is .jpg .bmp etc, how do i check if the file really is an image? so pple wont be able to change an exe file to jpg and upload it right away.

View 1 Replies View RelatedI was looking in the firebug debugger and noticed that my main .js file was somehow being called twice, but I don't see where. There are dozens of files involved in this particular problem, so I think the best way to go about solving it is to test - in run time - if my js file is already in place on the page, do nothing - otherwise call it. This is pseudo that I have monkeying around with but it's not working.
Code:
function checkFile() {
var fileExist = new fileExist();
fileExist.onLoad = isPresent;
[code]....
I thought this would work, perhaps it's because of an argument I need to pass in to checkFile(ZYX) but not sure.
Is there a way using javascript to have it check if a file exists on the server? I'm trying to check for a file on my server without having to refresh the open webpage. If this can't be done with javascript, do you know which webpage languange can execute this?
View 4 Replies View RelatedI'm try to set up a webpge that will play a live flash video on the left-hand side(got that part working) and display one slide of a presentation(jpg) to the right of the video. I would like to be able to control when the slide image changes by having some js check a text file on my server. The text file could contain something as simple as "Slide1.jpg". I will manipulate the text file with some code I've already written. Is there some simple js code I can put in my page that will cause it to check the text file every 5 seconds, and if the content of the file has changed, to refresh the image on the page with the new image? I'm try to get away from the "clicking" sound that is caused by doing a simple refresh of an Iframe.
View 3 Replies View RelatedI have recently bought the book: JavaScript & DHTML Cookbook. As I

This might be more of a firefox extension development question but it has to do with JS so i'll ask here in hopes of finding someone with experience in this.
My extension requires the URL of the image that was right clicked. Meaning I have added a new option in the right-click menu when an image is right-clicked that calls a function in my JS file
JavaScript Code:
imgSrc ();
This function requires the URL of the image that was right clicked to be passed into it. Does anyone know how I would do that?
I have a website in development that has some similarities to Kaboodle.com. I need a FF/IE toolbar button build that can extract images from a website and populate them into my db for display in my pages. This fucntion will work identical to how kaboodle.com works.
