"window.location.href" and "location.href" are the jumps to this page

"parent.location.href" are the jumps to the previous page

"top.location.href "is the outermost page jump

Example:

If A, B, C, and D are all jsp, D is the iframe of C, C is the iframe of B, and B is A's iframe, if the js in D writes

"window.location.href", "location.href": D page jumps to

"parent.location.href": C page Jump

"top.location.href": Jump to page A

If there is a form in page D,

: Jump to page D after the form is submitted. Go to

: A new page pops up after the form is submitted

: Page C jumps after the form is submitted

: Page A jumps after the form is submitted Go to

Regarding page refresh, write this in D page:

"parent.location.reload();": C page refresh (of course, you can also use the opener object of the child window to obtain Object of the parent window: window.opener.document.location.reload(); )

"top.location.reload();": A page refresh
