JS page jump Problem (jump to the parent page, the outermost page, this page)

"Window.location.href", "location.href" is this page jump

"Parent.location.href" is a page jump on the previous level

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

To illustrate:

If a,b,c,d are Jsp,d is C iframe,c is B's iframe,b is an IFRAME, if D JS so write

"Window.location.href", "location.href": D page Jump

"Parent.location.href": C page Jump

"Top.location.href": a page jump

If there is a form on the D page,

<form>: After form submission D page jump

<form target= "_blank";: New page pops up after form submission

<form target= "_parent";: C page jump after form submission

<form target= "_top" >: Form submitted after a page jump

About page refreshes, this is written in the D page:

"Parent.location.reload ();": C page Refresh (of course, you can also use the opener object of a child window to get the object of the parent window: Window.opener.document.location.reload (); ）

"Top.location.reload ();": a page refresh
