   [&LTFRAME SRC="<I>locationOrURL</I>" NAME="<I>frameName</I>"&GT]
&LT/FRAMESET&GT
</PRE>
<I>ROWS="rowHeightList"</I> is a comma-separated list of values specifying the row-height of the frame. An optional suffix defines the units. Default units are pixels.
<BR><I>COLS="columnWidthList"</I> is a comma-separated list of values specifying the column-width of the frame. An optional suffix defines the units. Default units are pixels.
<BR><I>&LTFRAME&GT</I> defines a frame.
<BR><I>SRC="locationOrURL"</I> specifies the URL of the document to be displayed in the frame. The URL cannot include an anchor name; for example <TT>&LTFRAME SRC="doc2.htm#colors" NAME="frame2"&GT</TT> is invalid. See the <A HREF="ref_h-l.htm#location_object" tppabs="http://www.nease.net/~jim/ref_h-l.htm#location_object">location</A> object for a 描述 of the URL components.
<BR><I>NAME="frameName"</I> specifies a name to be used as a target of hyperlink jumps.

<P>To use a frame object's properties:
<PRE>
1. [<I>windowReference</I>.]<I>frameName</I>.<I>propertyName</I>
2. [<I>windowReference</I>.]frames[<I>index</I>].<I>propertyName</I>
3. window.<I>propertyName</I>
4. self.<I>propertyName</I>
5. parent.<I>propertyName</I>
</PRE>
<I>windowReference</I> is a variable <I>windowVar</I> from a window definition (see <A HREF="ref_t-z.htm#window_object" tppabs="http://www.nease.net/~jim/ref_t-z.htm#window_object">window</A> object), or one of the synonyms top or parent.
<BR><I>frameName</I> is the value of the NAME attribute in the &LTFRAME&GT tag of a frame object.
<BR><I>index</I> is an integer representing a frame object.
<BR><I>propertyName</I> is one of the properties listed below.


<H3>Property of</H3>
<LI>The frame object is a property of <A HREF="ref_t-z.htm#window_object" tppabs="http://www.nease.net/~jim/ref_t-z.htm#window_object">window</A>
<LI>The frames array is a property of both <A HREF="ref_f-g.htm#frame_object" tppabs="http://www.nease.net/~jim/ref_f-g.htm#frame_object">frame</A> and <A HREF="ref_t-z.htm#window_object" tppabs="http://www.nease.net/~jim/ref_t-z.htm#window_object">window</A>


<H3>描述</H3>
<P>The &LTFRAMESET&GT tag is used in an htm document whose sole purpose is to define the layout of frames that make up a page. Each frame is a window object.

<P>If a &LTFRAME&GT tag contains SRC and NAME attributes, you can refer to that frame from a sibling frame by using <TT>parent.<I>frameName</I></TT> or <TT>parent.frames[<I>index</I>]</TT>. For example, if the fourth frame in a set has NAME="homeFrame", sibling frames can refer to that frame using <TT>parent.homeFrame</TT> or <TT>parent.frames[3]</TT>.

<P>The self and window properties are synonyms for the current frame, and you can optionally use them to refer to the current frame. You can use these properties to make your code more readable. See the properties listed below for 例子.

<P>The top and parent properties are also synonyms that can be used in place of the frame name. top refers to the top-most window that contains frames or nested framesets, and parent refers to the window containing the current frameset. See the <A HREF="ref_t-z.htm#top_property" tppabs="http://www.nease.net/~jim/ref_t-z.htm#top_property">top</A> and <A HREF="ref_m-q.htm#parent_property" tppabs="http://www.nease.net/~jim/ref_m-q.htm#parent_property">parent</A> properties.

<H4>The <I>frames</I> array</H4>
<P>You can reference the frame objects in your code by using the <I>frames</I> array. This array contains an entry for each child frame (&ltFRAME&gt tag) in a window containing a &LTFRAMESET&GT tag in source order. For example, if a window contains three child frames, these frames are reflected as <TT>parent.frames[0]</TT>, <TT>parent.frames[1]</TT>, and <TT>parent.frames[2]</TT>.

<P>To use the <I>frames</I> array:
<PRE>
1. [<I>frameReference</I>.]frames[<I>index</I>]
2. [<I>frameReference</I>.]frames.length
3. [<I>windowReference</I>.]frames[<I>index</I>]
4. [<I>windowReference</I>.]frames.length
</PRE>
<P><I>frameReference</I> is a valid way of referring to a frame, as described in the <A HREF="ref_f-g.htm#frame_object" tppabs="http://www.nease.net/~jim/ref_f-g.htm#frame_object">frame</A> object.
<BR><I>windowReference</I> is a variable <I>windowVar</I> from a window definition (see <A HREF="ref_t-z.htm#window_object" tppabs="http://www.nease.net/~jim/ref_t-z.htm#window_object">window</A> object), or one of the synonyms top or parent.
<BR><I>index</I> is an integer representing a frame in a parent window.

<P>To obtain the number of child frames in a window or frame, use the length property:
<PRE>
[<I>windowReference</I>.].frames.length
[<I>frameReference</I>.].frames.length
</PRE>

<P>Elements in the <I>frames</I> array are read-only. For example, the statement <TT><I>windowReference</I>.frames[0]="frame1"</TT> has no effect.

<P>The value of each element in the <I>frames</I> array is <TT>&ltobject <I>nameAttribute</I>&gt</TT>, where <I>nameAttribute</I> is the NAME attribute of the frame.


<H3>Properties</H3>
<P>The frame object has the following properties:
<LI><A HREF="ref_f-g.htm#frame_object" tppabs="http://www.nease.net/~jim/ref_f-g.htm#frame_object">frames</A> is an array reflecting all the frames in a window
<LI><A HREF="ref_m-q.htm#name_property" tppabs="http://www.nease.net/~jim/ref_m-q.htm#name_property">name</A> reflects the NAME attribute of the &LTFRAME&GT tag
<LI><A HREF="ref_h-l.htm#length_property" tppabs="http://www.nease.net/~jim/ref_h-l.htm#length_property">length</A> reflects the number of child frames within a frame
<LI><A HREF="ref_m-q.htm#parent_property" tppabs="http://www.nease.net/~jim/ref_m-q.htm#parent_property">parent</A> is a synonym for the window or frame containing the current frameset
<LI><A HREF="ref_s-s.htm#self_property" tppabs="http://www.nease.net/~jim/ref_s-s.htm#self_property">self</A> is a synonym for the current frame
<LI><A HREF="ref_t-z.htm#window_property" tppabs="http://www.nease.net/~jim/ref_t-z.htm#window_property">window</A> is a synonym for the current frame

<P>The <I>frames</I> array has the following properties:
<LI><A HREF="ref_h-l.htm#length_property" tppabs="http://www.nease.net/~jim/ref_h-l.htm#length_property">length</A> reflects the number of child frames within a frame


<H3>Methods</H3>

<LI><A HREF="ref_s-s.htm#setTimeout_method" tppabs="http://www.nease.net/~jim/ref_s-s.htm#setTimeout_method">setTimeout</A>


<H3>Event handlers</H3>
<LI>None. The onLoad and onUnload event handlers are specified in the &LTFRAMESET&GT tag but are actually event handlers for the window object.


<H3>例子</H3>
<P>The following example creates two windows, each with four frames. In the first window, the first frame contains pushbuttons that change the background colors of the frames in both windows.
