假设有一个 http://localhost:8080/项目下的 parent.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script>
function load() {
window.addEventListener("message",function(event){
console.log(event);
hello();
});
}
function hello() {
console.log("你好");
}
</script>
</head>
<body onload="load()">
<iframe src="http://dev.xcall.cn:8090/child.html"></iframe>
</body>
</html>
http://dev.xcall.cn:8090/项目下的 child.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script>
function submitHandler() {
window.parent.postMessage("closeAndRefresh",'http://localhost:8080/')
});
}
</script>
</head>
<body>
<button onclick="submitHandler()">提交申请</button>
</body>
</html>
关键代码
window.addEventListener("message",function(event){
console.log(event);
});
window.parent.postMessage("closeAndRefresh",'http://localhost:8080/')
获取子窗口 (反过来就好了)
document.getElementsByName("layui-layer-iframe1")[0].contentWindow;
或者
let win= document.getElementById("layui-layer-iframe1").contentWindow;
win.parent.postMessage("closeAndRefresh",'http://dev.xcall.cn:8090/')
