在div中隐藏/显示swf？

Question

I have a flex app that I want to hide in a div until the user clicks a link or element of some type. I've noticed that embedding the swf in a div with style display:none does not actually hide the swf, so how would I go about accomplishing this?

The goal is to have the flex app loading in the background while the user does other things. Thanks.

Try setting the following wmode to your flash object, and use visibility: hidden; as well.

<param name="wmode" value="opaque" />
<embed ... wmode="opaque" ... />

By default, flash basically overlays a window over your content, which is:

1. Has a greater z-index than anything on your page
2. Doesn't inherit display from its parent (setting display: none; visibility: hidden; to the <object> tag will work).

By setting wmode to opaque , it basically tells flash to treat your <object> as a normal DOM tag, which responds to normal inheritance and z-index rules. It has a very small performance cost.

Also, note that some browsers will not load the object until it is displayed.

I usually just force the height/width of the container to 1 by 1 px...

<div style="height:1px; width:1px;" >... flash goes here ...<div>

Then, when I need the flash, I will re-set the height/width as appropriate. Note, you may want to put this into a parent container if you want to just reset the hw to "100%" which will bind to a parent div, with a "position:relative; height:?px; width:?px" setting.
