Posté : 22 juin 2006, 23:15

Quand je fait
Est-ce qqun saurait ce qu'il faudrait modifier?
Merci

/**
* Convert a single file-input element into a 'multiple' input list
*
* Usage:
*
* 1. Create a file input element (no name)
* eg. <input type="file" id="first_file_element">
*
* 2. Create a DIV for the output to be written to
* eg. <div id="files_list"></div>
*
* 3. Instantiate a MultiSelector object, passing in the DIV and an (optional) maximum number of files
* eg. var multi_selector = new MultiSelector( document.getElementById( 'files_list' ), 3 );
*
* 4. Add the first element
* eg. multi_selector.addElement( document.getElementById( 'first_file_element' ) );
*
* 5. That's it.
*
* You might (will) want to play around with the addListRow() method to make the output prettier.
*
* You might also want to change the line
* element.name = 'file_' + this.count;
* ...to a naming convention that makes more sense to you.
*
* Licence:
* Use this however/wherever you like, just don't blame me if it breaks anything.
*
* Credit:
* If you're nice, you'll leave this bit:
