As shown in the picture, how to use js on page B to control page A to jump to a certain address?
If it is from the same source, just window.parent.location.href can be used directly. There is no solution if there are different sources and no control over the A page.
window.parent.location.href
In the js of the B pagewindow.parent.window.location.href = '//www.baidu.com'
window.parent.window.location.href = '//www.baidu.com'
<!DOCTYPE html> <html> <head> <title></title> <meta charset="utf-8"> </head> <body> <iframe src="b.html"></iframe> </body> </html>
<!DOCTYPE html> <html> <head> <title></title> <meta charset="utf-8"> <script type="text/javascript"> function parentJump() { window.parent.location.href = 'http://www.baidu.com/'; } </script> </head> <body> <button onclick="parentJump();">父页面跳到百度</button> </body> </html>
Use window.parent to access the parent form from a page in an iframe.
window.parent
