iframe 相互踩坑记录

//子页面
window.addEventListener('message',function(event) {
//console.log(event.data);
var iframe = document.getElementById('message');
event.source.postMessage('ok',event.origin);
},false);

//父页面
/*<iframe src="http://localhost:8779/parser/upload.html" width="1500" height="500" id="iframe"></iframe>

var interval = setInterval(function(){
var iframe = document.getElementById('iframe');
iframe.contentWindow.postMessage("发送内容", "*");

}, 2000);
window.addEventListener('message', function (event) {
// console.log(event.source);
// console.log(event);
if(event.data=='ok'){
clearInterval(interval);
}
}, false);*/
