强制Google Maps API仅使用Lat / Long值 - 修改预制JS

我正在为房地产网站使用Wordpress主题，主题具有以下功能：当您添加列表时，主题将使用列表 Headers （街道地址），以及“城市”和“州”标签，设置列表 Map 引脚 . 它也可以默认为lat / long（您可以在创建新列表时手动添加它）

由于想要为列表使用描述性 Headers 而不是街道地址，我希望 Map 仅根据纬度/经度放置引脚 . 当我使用描述性 Headers 时，列表 Map 不会加载 - 因此在 Map 未能对描述性 Headers 进行地理编码后， Map 不会默认为纬度/经度 .

映射代码如下（我不是专家所以一直在尝试许多更改，所有这些都打破了mappping函数！）

var estateMapping = (function () {
var self = {},
    marker_list = [],
    open_info_window = null,
    x_center_offset = 0, // x,y offset in px when map gets built with marker bounds
    y_center_offset = -100,
    x_info_offset = 0, // x,y offset in px when map pans to marker -- to accomodate infoBubble
    y_info_offset = -100;

function build_marker(latlng, property) {
    var marker = new MarkerWithLabel({
        map: self.map, 
        draggable: false,
        flat: true,
        labelContent: property.price,
        labelAnchor: new google.maps.Point(22, 0),
        labelClass: "label", // the CSS class for the label
        labelStyle: {opacity: 1},
        icon: 'wp-content/themes/realestate_3/images/blank.png',   
        position: latlng
        });

        self.bounds.extend(latlng);
        self.map.fitBounds(self.bounds);
        self.map.setCenter(convert_offset(self.bounds.getCenter(), x_center_offset, y_center_offset));

        var infoBubble = new InfoBubble({
            maxWidth: 275,
            content: contentString,
            borderRadius: 3,
            disableAutoPan: true
        });

        var residentialString = '';
        if(property['commercial'] != 'commercial') {
            var residentialString='<p class="details">'+property.bed+' br, '+property.bath+' ba';
        }

        var contentString =
        '<div class="info-content">'+
        '<a href="'+property.permalink+'"><img class="left" src="'+property.thumb+'" /></a>'+
        '<div class="listing-details left">'+

        var tabContent =

        '<img class="left" src="'+property.agentThumb+'" />'+
        '<div class="listing-details left">'+

        '<p class="tagline">'+property.agentTagline+'</p>'+

        '<p class="email"><a href="mailto:'+property.agentEmail+'">'+property.agentEmail+'</a></p>'+
        '</div>'+
        '</div>';

        infoBubble.addTab('Details', contentString);
        infoBubble.addTab('Contact Agent', tabContent);

        google.maps.event.addListener(marker, 'click', function() {

                self.map.panTo(convert_offset(this.position, x_info_offset, y_info_offset));
                open_info_window = infoBubble;
            }
        });
}

function geocode_and_place_marker(property) {
   var geocoder = new google.maps.Geocoder();
   var address = property.street+', '+property.city+' '+property.state+', '+property.zip;

       //If latlong exists build the marker, otherwise geocode then build the marker

           var lat = parseFloat(property['latlong'].split(',')[0]),

值得注意的是，上面的代码也适用于在主页 Map 上放置多个列表标记的功能 . 我希望 Map 总是从手动添加的纬度/经度（甚至是主页）中填充，但我不能在不破坏 Map 的情况下实现它...

任何信息将不胜感激 .
