如何解决使用复选框或表单提交过滤Google Map
| 我一直试图找出如何在单击复选框时使我的地图按三个不同区域过滤。 <style>
html,body { font-family:
Verdana,Geneva,Arial,Helvetica,sans-serif; }
#map { width: 1400px; height: 800px; border: 1px solid black; }
</style>
<body>
<div id=\"Filters\" style=\"margin:5px;background:#f4f4f4;border:1px solid #888;padding: 5px 5px 5px 10px;\">
<label style=\"color:#555;font-size:12px; font-weight:bold;\" for=\"tags\">Filter
by:</label>
<select id=\"tags\" style=\"outline:none;\">
<option value=\"all\">All</option>
<option value=\"Western\">Western</option>
<option value=\"Central\">Central</option>
<option value=\"Eastern\">Eastern</option>
</select>
</div>
<form action=\"#\"> All PC: <input type=\"checkbox\" id=\"all\" onclick=\"boxclick(this,\'allpc\')\" />
Western: <input type=\"checkbox\" id=\"Western\" onclick=\"boxclick(this,\'western\')\" />
Central: <input type=\"checkbox\" id=\"Central\" onclick=\"boxclick(this,\'central\')\" />
