Google Map 自定义 infowindow
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。
infobox.js 插件

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>).
