从JavaScript AS3函数调用 [英] AS3 function call from javascript
问题描述
我想从JavaScript调用一个函数AS3，但得到以下错误在浏览器：
I am trying to call a AS3 function from javascript but getting the following error in browser:
对象亘古不支持属性或方法myCreateFile。
Object doesnot support property or method myCreateFile .
下面是AS3类：
package {
import flash.display.Sprite;
import flash.external.ExternalInterface;
import flash.net.FileReference;
import flash.events.IOErrorEvent;
import flash.events.Event;
import flash.system.Security;
public class CreateDoc extends Sprite {
private static const DEFAULT_FILE_NAME:String = "example.txt";
//FileReference Class well will use to save data
private var fr:FileReference;
public function CreateDoc()
{
// Register the function for external use.
ExternalInterface.addCallback("myCreateFile", myCreateFile);
Security.allowDomain("*");
}
public function myCreateFile():void
{
fr = new FileReference();
//open a native save file dialog, using the default file name
fr.save("Demo file", DEFAULT_FILE_NAME);
fr = null;
}
}
}
HTML code：
HTML code:
<html>
<head>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
try{
var flashvars = {};
var params = {allowscriptaccess:"always", movie:"CreateDoc.swf", wmode:"opaque", menu:"false"};
var attributes = {id:"flashcontent", name:"flashcontent"};
swfobject.embedSWF("CreateDoc.swf", "flashcontent", "800", "600", "10.0.0", "expressInstall.swf", flashvars, params, attributes);
}
catch(err){
alert(err.message);
}
</script>
<script type="text/javascript">
function doFunction(){
alert('Calling function..');
try{
var myObj = document.getElementById("flashcontent");
myObj.myCreateFile();
}
catch(err){
alert(err.message);
}
}
</script>
</head>
<body>
<div id="flashcontent">
</div>
<input id="save file" type="button" value="clickme" onclick="doFunction();" />
</body>
任何想法是错误的，当我尝试调用myCreateFile（）AS3函数，它是从Java脚本CreateDoc类present？
Any idea what is wrong when I try to call the myCreateFile() AS3 function which is present in CreateDoc class from java script?
推荐答案
现在的问题是，你已经在三个地方使用相同的 ID 。更改 flashcontent 在这里：
swfobject.embedSWF（CreateDoc.swf，flashcontent，... 别的东西， UNIQUE_ID 例如，所以这将是： swfobject.embedSWF（CreateDoc.swf，UNIQUE_ID...... 使用后这个ID在这里：文档.getElementById（flashcontent）; 太像的document.getElementById（UNIQUE_ID）;
The problem is that you have used same id in three places. Change "flashcontent" here:
swfobject.embedSWF("CreateDoc.swf", "flashcontent" , ... to something else , unique_id for example , so it will be: swfobject.embedSWF("CreateDoc.swf", "unique_id" ... . After that use this id here : document.getElementById("flashcontent"); too , like document.getElementById("unique_id");
