Error In Javascript In Form To Check File Extension

May 1, 2007

actually there's no error in the code only that is only made to check for one input field and my form has 3 image upload fields, the original is:

<form enctype="multipart/form-data" action="action.php" method="post" onSubmit="if(!this.img1.value.match(/.jpg$/i)){alert('Must be JPG file');return false};return val(this)">
<input type="file" name="img1">
</form>

This works great but what modifications should have to be able to check multiple file input fields?

Checking The File Extension?

May 14, 2010

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).

Regular Expression For File Extension?

Sep 27, 2011

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.

Problem With IE And (ajax) File Upload Via Iframe: Javascript Error Access Denied/zugriff Verweigert

Feb 14, 2007

i want to do (multiple) file upload(s) and display a progress bar.
with firefox and safari it is no problem at all. only IE makes some
problems.

my script is based on ajax-uploader, which can be found at
www.srmiles.com/freestuff/ajax_file_uploader/ . you can do multiple
file uploads. each upload will have it's own "form"-tag, so that each
file is uploaded for its own. could be a good solution if there are
"big" uploads.

so here is what i do:

i have a html-page in which several forms with file-input fields are
generated. when i now hit the "one" submit button at the bottom of the
page a javascript function upload() starts it will iterate through all
forms (id='frmUpload_xx'), will get the filename, start a ajax request
for the progress-bar function and do a form.submit().

if the first form/file is uploaded, a settimeout('upload()', 1000); is
called and the next form will be processed. all form's have an
target="uploaddiv", where uploaddiv is a invisible iframe. so the
output of the upload script is put in this div. output should only be
a "OK" at the end. no usefull output no info no nothing.

firefox and safari are working as expected, only IE stops after the
first file is uploaded. i get an javascript error saying "zugriff
verweigert/access denied" on object line x... this is the place where
i call "form.submit()".

this is the upload-function:

function upload() {
if (uploads.length>0) {
form = document.getElementById('frmUpload_'+uploads[0]);
if (form["filename"].value == ""){
alert("Please Choose a file to upload.");
} else {
filename = form["filename"].value;
if (filename.lastIndexOf("")>0) {
filename = filename.substring(filename.lastIndexOf("")
+1,filename.length);
} else if (filename.lastIndexOf("/")>0) {
filename = filename.substring(filename.lastIndexOf("/")
+1,filename.length);
}
makeRequest("upload_progress.php?sid="+sid
+"&filename="+filename,progress);
form.submit();
}
}
}

the strange thing is, that filename is filled correct, that means the
object "form" is found and exisits. the first iteration is working,
only the second ends with an error.

think it have something to do with redirecting the output of the
upload-script in an iframe. after that IE can't access form - at least
IE is not allowed to submit the form as i can access a form field
(filename).
i worked on that the last two days and haven't found a solution...

Javascript Form Validation Error

Oct 15, 2007

I'm using Firefox with the Firebug add-on and whenever I load my test page with the contact form, I receive this error message in Firebug:

$(form).getElementsByTagName is not a function
getElements([])prototype.js (line 1799)
initialize("contact_form", Object immediate=true)validation.js (line 88)
create()

I've got this to work before on other sites, but for some reason it's not working on this site and I just don't know why and I don't understand what the error is telling me.

JQuery :: Form Validation Error Messages Not Showing / When Using File Input Plugin

Aug 8, 2011

I'm using the jQuery form validation plugin along with the fileinput plugin which hides the initial input area, but uses <divs> and some styling /javascript to show the file input field.The issue I am having, is that the 'this field is required' text that is meant to show on submission, doesn't come up for the file input field, nor some checkboxes that I have in a table. I am guessing that this is because the code is needing the label to be RIGHT next to the element (in this case the file input or the checkbox) in order for the validation message to show..Are there any work arounds that anyone knows of so that I can get the error message to show?Is there a way to show the error message for required fields when they have a div wrapping them or anything wrapping them?

How To Check The Input File Object File Size On Client Side?

Dec 20, 2004

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:

1. Malicious user trying to collapse the website sending big files.

2. Users that have not seen the warning “Maximum size: 100 KB&#65533; for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.&#65533; And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!


I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:

“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
