1.父页面调用子页面函数,选择iframe的id + contentWindow +子页面的函数名

2.子页面调用父页面函数,window.parent.父页面的函数名

父页面:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>父页面</title>
</head>
<body>
<div id="ss" style=" 400px;height: 400px; background: darkmagenta;">
<button id="chuancan" οnclick="chuandicanshu()">1</button>
</div>

<div id="main" style="position: fixed;left: 200px;top: 200px;background: red;">
<iframe id="childFrame" src="frame.html" width="100" height="100"></iframe>
</div>

<script type="text/javascript">
//调用子页面方法
function chuandicanshu(){
document.getElementById("childFrame").contentWindow.update("你好");
}
function closeParentWindow(){
document.getElementById("main").style.display = "none";
}
</script>
</body>
</html>
子页面:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>子页面</title>
</head>
<body>
<button id="close" οnclick="closeParentWindow()">关闭按钮</button>
<p id="canshu">父页面传过来的参数显示</p>
<script type="text/javascript">
function update(canshujuti){
document.getElementById("canshu").innerHTML = canshujuti;
}
function closeParentWindow(){
window.parent.closeParentWindow();
}
</script>
</body>
</html>
/////////////解码属性decodeURIComponent()
