iframe
There are two iframes inside. I want to ask now. There is a save function in the a.php page. I want to save the data and then query the data from the database and display it on the b.php page. How should I operate it? To put it bluntly Now, if I click save, how can I refresh the b.php page above? ? ?
Heroes help.

My idea is: set src and add timestamp to uri
ps: I am doing jsp development...
Write in a.php
In a.php write
Hello, I just tried your method, and the effect is that the a.php page is directly refreshed and displayed on the b.php page
The a and b pages are displayed the same, and they are displayed after manual refresh. Respective pages
After clicking save
Doesn’t page a need to be refreshed?
So page a should bring the js code to refresh page b
if(submission successful){
?>
<script> <br> window.onload=function(){ <br> var subWeb=parent.document.getElementById('b') ; <br> subWeb.src='b.php'; <br> } <br> ; </script>
}
?>
in a.php Add a code similar to this to the page
