HTMLInputElement.multiple

The HTMLInputElement.multiple property indicates if an input can have more than one value. Firefox currently only supports multiple for <input type="file">.

Example

// fileInput is a <input type=file multiple>
var fileInput = document.getElementById("myfileinput");

if (fileInput.multiple == true) {

    for (var i = 0, len = fileInput.files.length; i < len; i++) {
        // loop fileInput.files
    }

// only one file available
} else {
    var file = fileInput.files.item(0);
}
