JQuery :: Validation For Dynamic Field To Check The File Extension?

Aug 25, 2011

I am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.

For static files I use as
file: {
required:true,
accept: "png|jpg",
},

How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.

<input type="file" id="tval_1" name="tval_1" class="required accept" />

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?

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:

This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL.

Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.

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).

Html-file Where The User Inserts A Search Path For An Excel File?

Jan 28, 2010

I have one html-file where the user inserts a search path for an excel file. When the user clicks the button the data in the excel file should be presented in a <TABLE>. (Yeah, I know, activex only works in IE .. but that's good enough for this project)

The problem is .. I started out with a "fixed" search path for the excel file, so I didn't have the code in a function. That worked just fine. Once I added the function {} around the code it wouldn't work, it works just fine if I comment out the form-part and the function-part, and give the search path, of course.
It also works just fine if I use the function and form, but remove the <TABLE>- and <TR>-rows

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.
