保存点击谷歌地图标记ID -重置图标上的下一个标记单击

我应该指出，我正在使用高级自定义字段谷歌地图字段填充我的地图位置。

下面是渲染地图的各种函数:

/*

 *  @type    function

 */
function new_map(jQueryel) {
    // var
    var jQuerymarkers = jQueryel.find('.marker');
    // vars
    var args = {
        minZoom: 12,
        maxZoom: 17,
        center: new google.maps.LatLng(0, 0),
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        disableDefaultUI: true,
        scrollwheel: false,

    // create map               
    var map = new google.maps.Map(jQueryel[0], args);
    // add a markers reference
    map.markers = [];
    // add markers
    jQuerymarkers.each(function() {
        add_marker(jQuery(this), map);
    });
    // center map
    center_map(map);
    // return
    return map;
