JavaScript calls the Flash object's method (function) for five hours.

After a few hours, I found out that the road was wrong.

There is a problem with testing a JavaScript method to call an object in Flash on a Firefox browser today.

I had a whole afternoon of doing it.

I remember not having had such a problem before when I used Flash8.

My program is like this, I used flash to create a menu, by default, when the page opens, the menu is hidden, when the mouse is placed on a small icon, the menu is displayed, and will be based on the current page data situation, display a few items in the menu, while hiding a few items do not need to display the menu.

I used externalinterface.addcallback in Flash to register a method called: setmenuitemvisible (B:boolean)

Intended to be called in JavaScript in a Web page.

But who knows the program to write well, in the Internet Explorer run all normal, but in Firefox always prompt error:

The Setmenuitemvisible () method cannot be called in JavaScript.

I began to search Baidu, looking for one hours later, finally found a paper:

I have this piece of content in my Baidu space to collect a bit:

Originally because of browser reasons, if you do JavaScript on most browsers outside of IE call the function in Flash, generally in window.onload=function () {Load Flash}
Otherwise, some external functions that are registered in Flash cannot be called in JavaScript.

It was thought that the reason for this was found, but then came a very headache problem.

Because my flash is hidden first, after the JavaScript triggers the event, it only shows that I am using the

Flash.style.display= "None";
Flash.style.display= "";

When testing on Firefox found that when in this show and hide the two state of the transition, each flash will reload once, really faint!

Then to Baidu search a bit, found such an article, now I collected a bit:

The flash code was eventually rewritten because the previous code was logically not a good idea on Firefox.
