最近做的东西用到了infowindow,不过google提供的样式太难看了，于是想改变一下样式。看了一下好像infowindow的样式不太好改。
查了半天资料，看到一个infobox，感觉真的挺好用。提供了完整的api，样式的改变也容易。http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries里面还有其他的插件
都很好用。View example (infobox-basic.html)，这是他给的一个demo，样式也很简单。但是通过他的api，可以很容易就作出更改了。遇到改infowindow的可以试一下。

* @fileoverview InfoBox extends the Google Maps JavaScript API V3 <tt>OverlayView</tt> class.
* <p>
* An InfoBox behaves like a <tt>google.maps.InfoWindow</tt>, but it supports several
* additional properties for advanced styling. An InfoBox can also be used as a map label.
* <p>
* An InfoBox also fires the same events as a <tt>google.maps.InfoWindow</tt>.

* @name InfoBoxOptions
* @class This class represents the optional parameter passed to the {@link InfoBox} constructor.
* @property {string|Node} content The content of the InfoBox (plain text or an HTML DOM node).
* @property {boolean} disableAutoPan Disable auto-pan on <tt>open</tt> (default is <tt>false</tt>).
* @property {number} maxWidth The maximum width (in pixels) of the InfoBox. Set to 0 if no maximum.
* @property {Size} pixelOffset The offset (in pixels) from the top left corner of the InfoBox
* (or the bottom left corner if the <code>alignBottom</code> property is <code>true</code>)
* to the map pixel corresponding to <tt>position</tt>.
* @property {LatLng} position The geographic location at which to display the InfoBox.
* @property {number} zIndex The CSS z-index style value for the InfoBox.
* Note: This value overrides a zIndex setting specified in the <tt>boxStyle</tt> property.
* @property {string} boxClass The name of the CSS class defining the styles for the InfoBox container.
* The default name is <code>infoBox</code>.
* @property {Object} [boxStyle] An object literal whose properties define specific CSS
* style values to be applied to the InfoBox. Style values defined here override those that may
* be defined in the <code>boxClass</code> style sheet. If this property is changed after the
* InfoBox has been created, all previously set styles (except those defined in the style sheet)
* are removed from the InfoBox before the new style values are applied.
* @property {string} closeBoxMargin The CSS margin style value for the close box.
* The default is "2px" (a 2-pixel margin on all sides).
* @property {string} closeBoxURL The URL of the image representing the close box.
* Note: The default is the URL for Google's standard close box.
* Set this property to "" if no close box is required.
* @property {Size} infoBoxClearance Minimum offset (in pixels) from the InfoBox to the
* map edge after an auto-pan.
* @property {boolean} isHidden Hide the InfoBox on <tt>open</tt> (default is <tt>false</tt>).
* @property {boolean} alignBottom Align the bottom left corner of the InfoBox to the <code>position</code>
* location (default is <tt>false</tt> which means that the top left corner of the InfoBox is aligned).
* @property {string} pane The pane where the InfoBox is to appear (default is "floatPane").
* Set the pane to "mapPane" if the InfoBox is being used as a map label.
* Valid pane names are the property names for the <tt>google.maps.MapPanes</tt> object.
* @property {boolean} enableEventPropagation Propagate mousedown, click, dblclick,
* and contextmenu events in the InfoBox (default is <tt>false</tt> to mimic the behavior
* of a <tt>google.maps.InfoWindow</tt>). Set this property to <tt>true</tt> if the InfoBox
* is being used as a map label. iPhone note: This property setting has no effect; events are
* always propagated.

* An InfoBox behaves like a <tt>google.maps.InfoWindow</tt>, but it supports several

* <p>
* An InfoBox also fires the same events as a <tt>google.maps.InfoWindow</tt>.

* @name InfoBoxOptions
* @class This class represents the optional parameter passed to the {@link InfoBox} constructor.
* @property {string|Node} content The content of the InfoBox (plain text or an HTML DOM node).
* @property {boolean} disableAutoPan Disable auto-pan on <tt>open</tt> (default is <tt>false</tt>).
* @property {number} maxWidth The maximum width (in pixels) of the InfoBox. Set to 0 if no maximum.
* @property {Size} pixelOffset The offset (in pixels) from the top left corner of the InfoBox
* (or the bottom left corner if the <code>alignBottom</code> property is <code>true</code>)
* to the map pixel corresponding to <tt>position</tt>.
* @property {LatLng} position The geographic location at which to display the InfoBox.
* @property {number} zIndex The CSS z-index style value for the InfoBox.
* Note: This value overrides a zIndex setting specified in the <tt>boxStyle</tt> property.
* @property {string} boxClass The name of the CSS class defining the styles for the InfoBox container.
* The default name is <code>infoBox</code>.
* @property {Object} [boxStyle] An object literal whose properties define specific CSS
* style values to be applied to the InfoBox. Style values defined here override those that may
* be defined in the <code>boxClass</code> style sheet. If this property is changed after the
* InfoBox has been created, all previously set styles (except those defined in the style sheet)
* are removed from the InfoBox before the new style values are applied.
* @property {string} closeBoxMargin The CSS margin style value for the close box.
* The default is "2px" (a 2-pixel margin on all sides).
* @property {string} closeBoxURL The URL of the image representing the close box.
* Note: The default is the URL for Google's standard close box.
* Set this property to "" if no close box is required.
* @property {Size} infoBoxClearance Minimum offset (in pixels) from the InfoBox to the
* map edge after an auto-pan.
* @property {boolean} isHidden Hide the InfoBox on <tt>open</tt> (default is <tt>false</tt>).
* @property {boolean} alignBottom Align the bottom left corner of the InfoBox to the <code>position</code>
* location (default is <tt>false</tt> which means that the top left corner of the InfoBox is aligned).
* @property {string} pane The pane where the InfoBox is to appear (default is "floatPane").
* Set the pane to "mapPane" if the InfoBox is being used as a map label.
* Valid pane names are the property names for the <tt>google.maps.MapPanes</tt> object.
* @property {boolean} enableEventPropagation Propagate mousedown, click, dblclick,
* and contextmenu events in the InfoBox (default is <tt>false</tt> to mimic the behavior
* of a <tt>google.maps.InfoWindow</tt>). Set this property to <tt>true</tt> if the InfoBox
* is being used as a map label. iPhone note: This property setting has no effect; events are
* always propagated.
