修改工程目录下 html-template/index.template.html 文件
在<head></head> 中添加
<!-- add by hpf -->
<script src="js/hello.js" language="javascript"></script>
在<body></body>中添加
调用flex的按钮:
<button onclick="callFlex()">Call App</button>
最后的ndex.template.html 页面模板文件如下:

hello.js 文件中的内容如下:(js 文件位置: flex_src/js/hello.js)
function sayHelloWorld(str) { alert("flex call js success,params:"+str); } function callFlex() { var x = Flex2js.callFlex(); alert("call flex success!~"); }
over~~~
需要注意的是,我这个是web项目,部署到tomcat下执行一切正常
如果是纯Flex项目,可能用 alt+shift+x F 执行有问题
在MyEclipse里直接访问页面 bin-debug下面的 html页面则没有问题~
