Yes, I understand the problem; it's not new, and I understand that Chrome must
have tightened this policy.
I'm wondering if, just as we added the Input-Type-file (delegate), it would be
appropriate to add a "hidden button" that would call delegate.browser.
I've run a test. I created a button in the createDelegate() function, called
delegateFileButton, and in its "click" event I called delegate.click [1] and in
the browse function I launched a delegateFileButton.click() [2] but it didn't
work. ☹ (In FireFox it still works fine)
[1]
COMPILE::JS
public function createDelegate():void
{
delegate =
document.createElement('input') as WrappedHTMLElement;
delegate.setAttribute('type',
'file');
goog.events.listen(delegate,
'change', fileChangeHandler);
delegateFileButton =
document.createElement('button') as WrappedHTMLElement;
delegateFileButton.style.display
= "none";
delegateFileButton.onclick =
function():void {
delegate.click();
};
// I have also tried this:
/*
goog.events.listen(delegateFileButton, 'click',
function():void {
delegate.click();
} );
*/
}
[2] public function browse():void
{
COMPILE::SWF
{
delegate.browse();
}
COMPILE::JS
{
focusedButton =
document.activeElement as WrappedHTMLElement;
//trace("activeElement is: " + focusedButton);
focusedButton.addEventListener("blur", blurHandler);
focusedButton.addEventListener("focus", focusHandler);
window.addEventListener("keydown", keyHandler);
window.addEventListener("mousemove", mouseHandler);
window.addEventListener("mousedown", mouseHandler);
delegateFileButton.click();
}
}

Asunto: Re: mx.net.FileReference chrome
Browsers have certain security restrictions where you can't call certain APIs
unless the user has interacted with the page in some way. In this case, if you
want to call FileReference.browse(), it must be triggered by a listener for a
user gesture, such as mouse click or key down.
