javascript - 通过 Actionscript 调用 JS

Question

我正在尝试使用 ActionScript3 运行 Javascript。

这是绑定(bind)到按钮的代码:

import flash.external.ExternalInterface;

function call_javascript(evt:MouseEvent):void {
ExternalInterface.call("alert", "JS");
}

js_btn.addEventListener(MouseEvent.MOUSE_UP, call_javascript);

这是我的 HTML:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="550" height="400" id="js" align="middle">
    <param name="movie" value="js.swf" />
    <param name="quality" value="high" />
    <param name="bgcolor" value="#ffffff" />
    <param name="play" value="true" />
    <param name="loop" value="true" />
    <param name="wmode" value="window" />
    <param name="scale" value="showall" />
    <param name="menu" value="true" />
    <param name="devicefont" value="false" />
    <param name="salign" value="" />
    <param name='AllowScriptAccess' value='always'/>
    <!--[if !IE]>-->
    <object type="application/x-shockwave-flash" data="js.swf" width="550" height="400">
        <param name="movie" value="js.swf" />
        <param name="quality" value="high" />
        <param name="bgcolor" value="#ffffff" />
        <param name="play" value="true" />
        <param name="loop" value="true" />
        <param name="wmode" value="window" />
        <param name="scale" value="showall" />
        <param name="menu" value="true" />
        <param name="devicefont" value="false" />
        <param name="salign" value="" />
        <param name="allowScriptAccess" value="always" />
    <!--<![endif]-->

        </a>
    <!--[if !IE]>-->
    </object>

</object>

当我按下按钮时没有任何反应，为什么？我正在使用 FlashProfessional CS6

Answer 1

call() method将 js 函数名称和参数作为单独的参数。

试试这个:

ExternalInterface.call("alert", "JS");

编辑:您还需要 allow script access在您的 HTML 页面中。

将此添加到您的 SWF 容器 HTML 页面

<param name='AllowScriptAccess' value='always'/>

例如:

<object id='MyMovie.swf' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='http://download.adobe.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0' height='100%' width='100%'> 
<param name='AllowScriptAccess' value='always'/> 
<param name='src' value=''MyMovie.swf'/> 
<embed name='MyMovie.swf' pluginspage='http://www.adobe.com/go/getflashplayer' src='MyMovie.swf' height='100%' width='100%' AllowScriptAccess='never'/> 
</object> 

编辑 2: 仅当文件属于本地信任的安全沙箱时，在本地运行此程序才有效。来自文档:

For SWF files running locally, calls to these methods are successful only if the SWF file and the containing web page (if there is one) are in the local-trusted security sandbox. Calls to these methods fail if the content is in the local-with-networking or local-with-filesystem sandbox.
