Question

hello everyone i want validate the type of file being uploaded on sever to .txt extension. Can i use accept attribute of input element to filter out the type of file. If yes how can i do that and if any other way ??

Some code is

   <input type="file"     name="uploadfile" value="" size="50" /> 

Thanks

Answer 1

here is javascript custom validation

var files = document.getElementsByName("uploadfile");
if(files[0].value.indexOf(".txt") == -1) {
// Code placed here will be executed if an invalid file type is found.
}

And yes you can use accept attribute as well:

<input accept="audio/*|video/*|image/*|MIME_type" />

However as far as I know it is not supported by IE and Safari

But please make sure to validate the uploaded file on the server side as well. Just client validation is not enough.
