In JavaScript can I make a "click" event fire programmatically for a file input element?

I'd like to make a click event fire on an <input type="file"> tag programmatically. Just calling click() doesn't seem to do anything or at least it doesn't pop up a file selection dialog.

Why does firefox say "connection partially encrypted" on this page?

Here's the page: https://www.testmasters.net/test/ssltest2.aspx When I go to it (in firefox or chrome), it says "connection partially encrypted".

I'm doing some optimising for my site and am trying to figure out just how big some inline code can be before it can justify having it's own file instead of being written inline.

How do I constrain the size of a tooltip/popup-style DIV so that it doesn't trigger scrollbars on the page

The mouse hovers over an element and a tip appears. The tip overflows the page, triggering a scrollbar, which changes the layout just enough so that the underlying element that triggered the tip is no longer under the mouse pointer, so the tip goes away. The tip goes away, so the scrollbar goes away, and now the mouse is again over th...

How can I troubleshoot Rendering Performance issues in IE

Our web application renders fast in some IE browsers, slow in others... It seems to be an HTML rendering problem...

Seems to be isolated to some users/configurations of ie...

I use a custom-built asp.net control that renders to a DIV and has "height='0'" hard-coded into the element (I know.. stupid). But I need to reset it - get rid of the height assignment somehow.

I have a single image with 9 different states and the appropriate background-position rules set up as classes to show the different states.
