嗨,我在iframe中有两个页面(index.html,another-one.html)。 index.html有一个重定向到another-one.html的按钮 另一个one.html使用window.top.postMessage发送了邮件,导致其重定向回初始邮件。
预计应保留在index.html
装有index.html的主机页面或容器页面
主机页面代码
<iframe src ="http://127.0.0.1:8888/index.html" name="example" id="example" application="yes">
</iframe>
主机页面中的js代码
window.addEventListener("message", (e)=>{
if(e && e.data){
this.pagedata = e.data;
}
}, false);
