我试图从JS调用call action脚本函数,但是我收到以下错误

   Error: getFlashMovie(swfobjectID).sayWhat is not a function

任何身体都可以让我知道我在这里做错了什么

     <html>

     <OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="myMovieName" WIDTH="225" HEIGHT="200">
     <PARAM NAME="movie" VALUE="ax.swf" /> <PARAM NAME="quality" VALUE="high" /> <PARAM NAME="bgcolor" VALUE="#FFFFFF" /> <EMBED href="ax.swf" src="ax.swf" quality=high bgcolor=#FFFFFF NAME="myMovieName" ALIGN="" TYPE="application/x-shockwave-flash"> </EMBED> </OBJECT>



     <script>
     function getFlashMovie(movieName) {
        alert("In get Flash Movie");
         document.getElementById(movieName).setAttribute("name", movieName);
         var isIE = navigator.appName.indexOf("Microsoft") != -1;
         return (isIE) ? window[movieName] : document[movieName];
     }

     function sayWhat()
     {
        alert("In call as");
        var swfobjectID = 'myMovieName';  
        alert(swfobjectID);
        //call flex function 
        getFlashMovie(swfobjectID).sayWhat();
     }
     </script>
     <input type="button" onclick="javascript:sayWhat();" value="Click Me" />

您可能需要在js中使用其他类型的解决方法从任何浏览器调用flash函数。

在这里,我分享我的方法来完成这个(希望它还没有被弃用......)。你需要一个javascript类(我把它命名为FO):

/**
 * 
 * @param id
 * @param swf
 * @param width
 * @param height
 * @param scriptAccess
 * @param allowFullscreen
 * @return
 */
function FO(id, swf, width, height, scriptAccess, allowFullscreen){
    this.id = id;
    this.movie = swf;
    this.height = height ? height : 180;
    this.width = width ? width : 240;
    this.scriptAccess = scriptAccess ? scriptAccess : "always";
    this.allowFullscr = allowFullscreen ? "true" : "false";
    this.obj = document.createElement("embed");
    this.obj.src = this.movie;
    this.obj.width = this.width;
    this.obj.height = this.height;
    this.obj.name = this.id;
    this.obj.id = this.id;
    this.obj.align = "middle";
    this.obj.type = "application/x-shockwave-flash";
    this.obj.setAttribute("quality", "high");
    this.obj.setAttribute("bgColor", "#bee3f6");
    this.obj.setAttribute("play", "true");
    this.obj.setAttribute("loop", "false");
    this.obj.setAttribute("allowScriptAccess", this.scriptAccess);
    this.obj.setAttribute("allowFullscreen", this.allowFullscr);
    this.obj.setAttribute("pluginspage", "http://www.adobe.com/go/getflashplayer");
}
FO.prototype = {
    id :null,
    width :null,
    height :null,
    movie :null,
    scriptAccess :null,
    allowFullscr :null,
    obj :null,

    addParam : function(name, value){
        var p = document.createElement("param");
        p.name = name;
        p.value = value;
        this.obj.appendChild(p);
    }
};

您需要一个初始化方法(或扩展现有方法):

// should be called on window.onload
function init() {
    var flashObject = null;
    if (isIE)
        flashObject = document.getElementById("myMovieName");
    else 
    {
        flashObject = new FO("myMovieName", "ax.swf", 225, 200).obj;
        // **app** is the id of a div / html container element, 
        // in which your <object> is positioned. 
        document.getElementById("app").appendChild(flashObject);
    }
}
window.onload = init;

并且用于调用所需的方法:

//somewhere else in your code:
if (flashObject)
    flashObject.sayWhat();

这是一个工作示例应用程序,它从javascript调用你的flex sayWhat功能。

它包含4个文件:ax.mxmlcall_flfunc.htmlax.jsax.css
您应该将最后三个文件和生成的ax.swf文件放在Web服务器上的相同文件夹中(或修改它们被引用的路径),它将起作用。

ax.mxml :您的主要Flex应用程序的结构

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" 
    width="300" height="300" backgroundColor="#bee3f6"
    creationComplete="onCreationComplete()">
    <mx:Script>
        <![CDATA[

            import mx.controls.Alert;

            public function sayWhat():void {
                Alert.show("Hi");
            }

            public function onCreationComplete():void {
                Security.allowDomain("localhost");

                // binds this.sayWhat to the external interface, so when from   
                // javascript is called the compiled swf object's sayWhat function,
                // it will be transferred to this.sayWhat. 
                ExternalInterface.addCallback("sayWhat", sayWhat);

                // The next line tells the external interface (the parent application:
                // browser window), that this application has finished loading, its 
                // ready to be used.
                // In js there has to be a global method with this name.
                ExternalInterface.call("onFlashAppInited");
            }        

        ]]>

    overflow: hidden;
    white-space: nowrap;
    text-align: center;
}
#tmp {
    display: none;
    visible: false;
}

我希望这是可以理解的,你可以从中工作。

从javascript调用时尝试:

myMovieName.sayWhat();
