History
The History
interface of the History API allows manipulan of the browser session history, that is the pages in the tab or frame that the current page is loaded in.我的
There is only one instance of history
(It is a singleton.) accessible via the global object history
.
Instance properties
The History
interface doesn't inherit any property.
-
length
Read only -
Returns an
Integer
representing the number of elements in the session history, including the currently loaded page. For example, for a page loaded in a new tab this property returns1
. scrollRestoration
-
Allows web applications to explicitly set default scroll restoration behavior on history navigation. This property can be either
auto
ormanual
. -
state
Read only -
Returns an
any
value representing the state at the top of the history stack. This is a way to look at the state without having to wait for apopstate
event.
Instance methods
The History
interface doesn't inherit any methods.
back()
-
This asynchronous method goes to the previous page in session history, the same action as when the user clicks the browser's Back button. Equivalent to
history.go(-1)
.Calling this method to go back beyond the first page in the session history has no effect and doesn't raise an exception.
forward()
-
This asynchronous method goes to the next page in session history, the same action as when the user clicks the browser's Forward button; this is equivalent to
history.go(1)
.Calling this method to go forward beyond the most recent page in the session history has no effect and doesn't raise an exception.
go()
-
Asynchronously loads a page from the session history, identified by its relative location to the current page, for example
-1
for the previous page or1
for the next page. If you specify an out-of-bounds value (for instance, specifying-1
when there are no previously-visited pages in the session history), this method silently has no effect. Callinggo()
without parameters or a value of0
reloads the current page. pushState()
-
Pushes the given data onto the session history stack with the specified title (and, if provided, URL). The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized. Note that all browsers but Safari currently ignore the title parameter. For more information, see Working with the History API.
replaceState()
-
Updates the most recent entry on the history stack to have the specified data, title, and, if provided, URL. The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized. Note that all browsers but Safari currently ignore the title parameter. For more information, see Working with the History API.
