IE8 blur handling doesn't always play nice

[jeroenp]

Hi,

I get a

"htmlfile: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."

on $input.focus() in the onblur handler for IE8;

https://github.com/ChiperSoft/Kalendae/blob/master/src/input.js#L53

That's because I have another blur handler on the same input that causes display:none on the input and its surrounding HTML. Apparently my blur handler has been called before Kalendae, and IE8 doesn't like calling focus() on a hidden input element. And it shouldn't, because the blur is rightly called on the input and I'm done with the calendar editing at this point.

As far as I can tell, I have no way to manipulate the noclose variable. I would think that the hide() should set this variable as well. I don't even understand why noclose was set to true anyhow.

The $input is not a jquery object, by the way. It's the native HTMLDOMElement. I'm not sure if that's what you were expecting, given the variable name prefix...

kind regards, Jeroen

I've added a try/catch in my copy of kalendae, because I can't imagine ever being interested in failures on focus() requests:

    util.addEvent($input, 'blur', function () {
        if (noclose) {
            noclose = false;
            try {
                $input.focus();
            } catch (x) {
                ;
            }
        }
        else self.hide();
    });
