如何完全屏蔽网页中FLASH里F5刷新及功能键
【问题需求描述】
使用flash开发的课件，交互性虽好，但是加入用户在学习过程中无意或有意按了F5，则flash会重新载入，前面的就白学了
【要解决的问题】
1.屏蔽网页里的F5刷新及功能键
2.取消由于M$改变active的机制后造成的flash空间需要激活的虚框提示
3.屏蔽焦点位于flash上时造成的针对1的解决方案所不足的刷新
【解决步骤】
1.要屏蔽网页里的F5及功能键，需要先用js判断浏览器类型，由于不同浏览器返回的事件对象以及获得事件对象keycode的方法都不一样，故用到BrowserCompatible.js来解决浏览器兼容性问题。主要代码如下：
[cc lang="js"]
//
document.onkeydown=keyDown;
function keyDown(e)
{
if(e==null)
e=BrowserCompatible.getEvent(e);
var keycode=BrowserCompatible.getKeyCode(e);
if ( keycode >=112 && keycode<=123 )
{
alert(keycode);
if(navigator.appName.indexOf("Microsoft") != -1){
e.keyCode = 0;
e.cancelBubble = true;
e.returnvalue = false;
}
return false;
//
[/cc]
2，网页的F5屏蔽和功能键都已成功，接下来就要屏蔽flash中的了，我的思路是当flash获得焦点的时候，自动将焦点再还给浏览器。具体方法如下，首先flash初始时监听mousedown事件,利用flash中的ExternalInterface.call，来调用js，使浏览器重新获得焦点。js代码如下：
[cc lang="js"]
function htmlFocus()
{
document.body.focus();
}
[/cc]
3，但是这样做的话，flash所有的键盘事件都无法被flash所获取，若需要flash获取键盘事件的话，还需把浏览器事件所产生的keycode再传回来，利用flash中的ExternalInterface.addcall()来接受js的值，具体代码如下：
[cc lang="js"]
function getMovie(movieName) {
if(navigator.appName.indexOf("Microsoft") != -1){
return window[movieName];
}
else {
if(document[movieName].length != undefined) { return document[movieName][1]; }
return document[movieName];
}
}
getMove("flash").sendKeyCode(event.keyCode);
