Several access methods for frame Objects in Javascript

The Helper House (www.bkjia.com) Tutorial in js calls the frames set in the window object by accessing the frame. The methods for accessing frame are as follows:

Reference content is as follows: Window. parent. frames [frame index location]; Window. parent. frames. frame name; Window. parent. frames ["frame name"]; Parent. frames. item [frame index location]; Parent. frames. item ["frame name"]; Parent. frame name

If it is at the top layer, you can also use the window. top. frame name for access. For example, there is a frameset as follows. We will access the bottom object in top.

Reference content is as follows: <Frameset> <Frame name = "top"/> <Frame name = "bottom"/> </Frameset>

The access code is as follows:

Reference content is as follows: // Ask bottom on the Top page Window. parent. frames [1]; Window. parent. frames. bottom; Window. parent. frames ["bottom"]; Parent. frames. item [1]; Parent. frames. item ["bottom"]; Parent. bottom Parent ["bottom"] // If it is on the Top layer, you can use the window. Top object to select Window. top. bottom;
