Ideas and codes for implementing iframe in html to control the refresh of parent page
|
1. Application Scenarios Parent page a.jsp Subpage b.jsp, as the page pointed to by the iframe embedded in page a Copy code The code is as follows:<body> <iframe id="frame" src="b.jsp" .../> </body> Now an operation is performed 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 the iframe. 3. Implementation In b.jsp Copy code The code is as follows:function refresh(){ var frame = window.parent.document.getElementById("frame"); var path = frame.getAttribute("src"); frame.setAttribute("src", path); } This only refreshes the frame, achieving a partial refresh effect. |
