forward
Points the browser to the next URL in the current history list;
equivalent to the user pressing the browser's Forward button
方法源 Window
实现版本 Navigator 4.0
语法
history.forward() forward()
参数
无
描述
This method performs the same action as a user choosing the Forward button in the browser. The forward method is the same as history.go(1).
When used with the Frame object, forward behaves as follows: While in Frame A, you click the Back button to change Frame A's content. You then
move to Frame B and click the Back button to change Frame B's content. If you move back to Frame A and call FrameA.forward(), the content of Frame B changes (clicking the Forward button behaves the same). If you want to navigate Frame A separately, use FrameA.history.forward().
示例
The following custom buttons perform the same operation as the browser's Forward button:
<P><INPUT TYPE="button"
VALUE="< Go Forth"
onClick="history.forward()">
<P><INPUT TYPE="button"
VALUE="> Go Forth"
onClick="myWindow.forward()">
