Flash到JavaScript的通信
从HTML可以发送数据到Flash,反过来也可以. 这个例子演示了如何应用Flash的Fscommand来发送数据到JavaScript.
查看示例:示例2
下载源文件: flash_to_javascript.zip(10K)
简要步骤:
Flash中
新建一个文件,保存为flash_to_javascript.fla
创建一个文本域,设置成输入文本(Input Text),选择"border"以便我们能看到他,指定他的变量为inputVar
创建一个按钮,在按钮上添加如下的as:
on (release) {
fscommand ("send_var", inputVar);
}
保存文件,导出HTML和SWF
Dreamweaver中
1.打开导出HTML文件,修改<OBJECT>和<EMBED>标签,结果同上:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/
flash/swflash.cab#version=5,0,0,0"
width=366 height=142 id="myFlash">
<embed src="javascript_to_flash.swf" quality=high
width=366 height=142
type="application/x-shockwave-flash"
pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?
P1_Prod_Version=ShockwaveFlash" name="myFlash" swLiveConnect="true">
</embed>
2. 插入如下的Javascript到<Body>标签内:
<SCRIPT LANGUAGE=JavaScript>
<!–
var InternetExplorer = navigator.appName.indexOf("Microsoft") != -1;
function myFlash_DoFSCommand(command, args) {
var myFlashObj = InternetExplorer ? myFlash : document.myFlash;
alert (args);
}
if (navigator.appName && navigator.appName.indexOf("Microsoft") != -1 &&
navigator.userAgent.indexOf("Windows") != -1 && navigator.userAgent.indexOf("Windows 3.1") == -1) {
document.write('<SCRIPT LANGUAGE=VBScript\> \n');
document.write('on error resume next \n');
document.write('Sub myFlash_FSCommand(ByVal command, ByVal args)\n');
document.write(' call myFlash_DoFSCommand(command, args)\n');
document.write('end sub\n');
document.write('</SCRIPT\> \n');
}
//–>
</SCRIPT>
