<script>
function abc(){
timer = setInterval('addListener()',1000)
}
function addListener(){
cpWindow = window.frames["contentIFrame"];

cpWindow.cpAPIEventEmitter.addEventListener("CPAPI_MOVIEPAUSE",function(a,b,c,d){
alert(7);
});
clearInterval(timer);
}
}
</script>
</html>
触发事件，脱离iframei显示的页面

重点解析：
window.parent.location.href="${pageContext.request.contextPath}/cw/playCw.do?cwId="+obj;
当前iframe的父框架显示内容
window.parent.contentIFrame.location.href="${pageContext.request.contextPath}/cw/playCw.do?cwId="+obj";
window.parent取父框架显示
window.parent.contentIFrame取子框架显示
