actionscript3与javascript通信

来源：互联网发布：淘宝说已失效编辑：程序博客网时间：2024/05/18 19:20

注意：jsp文件和swf文件都放在跟目录下，加上跨域允许访问文件。

详细编写请参考flash cs3 帮助文档，里面有完整的例子。

1.jsp页面。

<%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=utf-8" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>

swfobject.registerObject("myFlashContent", "9.0.0", "expressInstall.swf");

var jsReady = false;

function isReady() {

return jsReady;

}

function pageInit() {

jsReady = true;

//document.forms["form1"].output.value += " " + "JavaScript is ready. ";

}

function thisMovie(movieName) {

if (navigator.appName.indexOf("Microsoft") != -1) {

return window[movieName];

} else {

return document[movieName];

}

function sendToActionScript(value) {

thisMovie("myFlashContent").sendToActionScript(value);

}

function sendToJavaScript(value) {

document.forms["form1"].output.value += "ActionScript says: " + value + " ";

}

</script>

</head>

</a>

</object>

</object>

</div>

<textarea cols="60" rows="20" name="output" readonly="true">Initializing...</textarea>

</form>

</body>

</html>
