go method
Loads a URL from the history list.
语法history.go(delta | "location")
delta is an integer or a property of an existing object, representing a relative position in the history list.
location is a string or a property of an existing object, representing all or part of a URL in the history list.
方法
描述
The go method navigates to the location in the history list determined by the argument that you specify. You can interactively display the history list by choosing History from the Window menu. Up to 10 items in the history list are also displayed on the Go menu.
The delta argument is a positive or negative integer. If delta is greater than zero, the go method loads the URL that is that number of entries forward in the history list; otherwise, it loads the URL that is that number of entries backward in the history list. If delta is 0, Navigator reloads the current page.
The location argument is a string. Use location to load the nearest history entry whose URL contains location as a substring. The location to URL matching is case-insensitive. Each section of a URL contains different information. See the location object for a 描述 of the URL components.
例子
The following button navigates to the nearest history entry that contains the string "home.netscape.com": <P><INPUT TYPE="button" VALUE="Go"
onClick="history.go('home.netscape.com')">
The following button navigates to the URL that is three entries backward in the history list: <P><INPUT TYPE="button" VALUE="Go"
onClick="history.go(-3)">
