google maps api 3 - Select Link or Checkbox to Display Category Markers -


i stuck @ trying tell javascript want do.

i have example map http://calwestcultural.com/sgs/backup/example-map.html , have categories in spry menu left. categories clickable , reveal markers category.

i'd to: 1. hide markers on load 2. when click on category (for example "eat" "banks" etc) i'd markers within category show

*if creating checkbox within menu makes easier, willing that. hung on part of map , need move on.

can please help? tells me easy fix.

if keep markers in separate categories, create array each category of marker , use them store each set of markers. following:

to hide markers on load, create markers leave marker map property set null:

var mylatlng = new google.maps.latlng(-25.363882,131.044922); var myoptions = {     zoom: 4,     center: mylatlng,     maptypeid: google.maps.maptypeid.roadmap }; var map = new google.maps.map(document.getelementbyid("map_canvas"), myoptions); var marker = new google.maps.marker({     position: mylatlng,     map: null,     title:"hello world!" });

to show markers in given category, listen event should trigger display of markers , set markers' map property:

for ( var = 0; < markercategoryarray.length; i++ ) {     markercategoryarray[i].setmap( map ); }
