javascript - 带有 iframe 的 Google map 在页面加载后不起作用

Question

我的谷歌地图在我的网站上运行良好:

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

我应该改变它，因为 GTmetrix。所以我决定在加载页面时加载它，这是我的新代码，它不加载 map 。

 <iframe id='iframe1' ></iframe>

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

注意:这是我的 Gtmetrix 问题，只是分享以完成我的问题:

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

There is 1 redirect

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

Answer 1

使用您的代码:

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

javscript 控制台中有一条消息:

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，它可以工作(请注意，源是在附加到 DOM 之前设置的):

 <script>
   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);
   });
 </script>

代码片段:

<div id="anchor"></div>

<script>
  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);
  });

</script>
