Question

I have prblem with dynamically created RegExp object (in the file upload plugin)

This is a initialization code of the plugin:

$('#fileupload').fileupload('option', {
    acceptFileTypes: /(\.|\/)(doc|pdf)$/i
});

That code changes the regex:

$('#files-list').change(function() {
   $('#fileupload').fileupload(
            'option',
            'acceptFileTypes',
            new RegExp('(\.|\/)('+$(this).find(":selected").attr('f-ext')+')$/i')
                );
            });

and it adds the / char at the beggining and at the end of that regex.

See the image below. The 1st & 2nd line is after the plugin initialization, the 3rd and the 4th line. That causes the file name validation fail.

How to fix it ?

Answer 1

To use case insensitive modifier you should do the next

new RegExp( regexp_expression , 'i' );
