1.父域页面(a.html)：act/msg/evalStr 为自定义属性
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<input type="text" id="textValue"/>
<input type="button" value="获取跨域的页面内容" onclick="method1()"/>
<br/>
<hr/>
<iframe src="http://127.0.0.1:8821/b.html" width="500" height="500" id="iframe1" name="iframe1"></iframe>
<script>
function method1(){
var frm = document.getElementById("iframe1");
frm.contentWindow.postMessage({
act: 'article', // 自定义的消息类型、行为，用于switch条件判断等。。
msg: {
evalStr: 'alert("跨域成功！")'
}
},"*");
}
var OnMessage = function (e) {
if (e.data.act == 'response') {
var textValue = document.getElementById("textValue");
textValue.value=e.data.msg.reportFormId;
} else {
alert('未定义的消息: '+ e.data.act);
}
}
if (window.addEventListener) { // all browsers except IE before version 9
window.addEventListener("message", OnMessage, false);
} else {
if (window.attachEvent) { // IE before version 9
window.attachEvent("onmessage", OnMessage);
}
}
</script>
</body>
</html>
2.子域页面（b.html）:
<!DOCTYPE html>
<html>
<head>
<title>子域</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=width-device,initial-scale=1.0,user-scalable=no" />
</head>
<body>
<div><h1>这是子域内容</h1></div>
<script>
var reportFormId = 'www.thunisoft.com';
var OnMessage = function (e) {
if (e.data.act == 'article') {
//触发编辑页面的保存事件或者添加eval方法
eval(e.data.msg.evalStr);
// 向父窗框返回响应结果
window.parent.postMessage({
act: 'response',
msg: {
reportFormId: reportFormId //报表id
}
}, '*');
} else {
alert('未定义的消息: '+ e.data.act);
}
}
if (window.addEventListener) { // all browsers except IE before version 9
window.addEventListener("message", OnMessage, false);
} else {
if (window.attachEvent) { // IE before version 9
window.attachEvent("onmessage", OnMessage);
}
}
</script>
</body>
</html>
