关于javascript：页面加载后，带有iframe的Google Maps无法正常工作


Google Maps with iframe doesn't work after page load

我的Google地图在我的网站上运行正常：

1
<iframe id='iframe1' src="https://maps.google.com/maps?q=25.1954875,-111.6649204&hl=fa;z=14&ie=UTF8&output=embed&hl=en"></iframex>

由于GTmetrix，我应该更改它。因此，我决定在加载页面时加载它，这是我的新代码，它不会加载地图。

 <iframe id='iframe1' ></iframex>

   
        window.addEventListener("load", function() {
            document.getElementById('iframe1').src = 'https://maps.google.com/maps?q=25.1954875,-111.6649204&hl=fa;z=14&ie=UTF8&output=embed&hl=en';
        });

注意：这是我与Gtmetrix有关的问题，只需分享即可完成我的问题：

There are 5 static components without a far-future expiration date.

There is 1 redirect

1
https://maps.google.com/maps?... redirects to https://www.google.com/maps/embed?...

使用您的代码：

 <iframe id='iframe1' src="about:blank"></iframex>
 
   window.addEventListener("load", function() {
     document.getElementById('iframe1').src = 'https://maps.google.com/maps?q=25.1954875,-111.6649204&hl=fa;z=14&ie=UTF8&output=embed&hl=en';
   });

在javscript控制台中有一条消息：

1
Refused to display 'https://www.google.com/maps?q=25.1954875,-111.6649204&hl=fa;z%3D14&ie=UTF8&output=embed&hl=en' in a frame because it set 'X-Frame-Options' to 'sameorigin'.

但是，如果<iframe>也是动态创建的，则它也可以工作(请注意，在将源附加到DOM之前已设置了源)：

   window.addEventListener("load", function() {
     var iDiv = document.createElement('iframe');
     iDiv.id = 'iframe1';
     iDiv.src = 'https://maps.google.com/maps?q=25.1954875,-111.6649204&hl=fa;z=14&ie=UTF8&output=embed&hl=en';
     document.getElementById("anchor").appendChild(iDiv);
   });
