1. Application scenarios Parent page a.jsp
Child page b.jsp, as the page pointed to by the iframe embedded in page a
Now an operation is done in page b. After the operation is completed, the iframe embedded in page a needs to be refreshed.
2. Ideas Find page a in page b, then find the iframe in page a, and reassign the src attribute of iframe.
3. Implementation in b.jsp
function refresh(){
var frame = window.parent.document.getElementById("frame");
var path = frame.getAttribute ("src");
frame.setAttribute("src", path);
}
This only refreshes the frame, which is a partial refresh effect.
