how to access element id which belongs to another html page?
提问by s.onal
i have a javascript problem
我有一个 javascript 问题
there are three html page like 'page1.html', 'anotherPage.html' and anotherPage.html
有三个 html 页面，如“page1.html”、“anotherPage.html”和 anotherPage.html
FOR page1.html
对于 page1.html
<div id='mainFrame'></div>
<ul><li onclick="updateFrame(id,"anotherPage.html");"><a href="javascript:;"></a></li></ul>
FOR anotherPage.html
FOR anotherPage.html
<ul><li onclick="updateFrame(id,anotherPage2);"><a href="javascript:;"></a></li></ul>
my javascript function:
我的 javascript 函数：
function updateFrame(id,url){
document.getElementById(id).innerHTML="<iframe scrolling='no' style='height:2000px;position:absolute;width:100%;height:100%;left:10px;border-style:none' src=\" "+ url+ "\"></iframe>";}
The problem is that when i called java script in iframe, javascript did not find the parent document id. How can i access the parent document id ? (Parent document is another html page in this case)
问题是当我在 iframe 中调用 java 脚本时，javascript 没有找到父文档 ID。如何访问父文档 ID？（在这种情况下，父文档是另一个 html 页面）
Thanks.
