我不明白爲什麼這不起作用。地圖不加載

Question

我很確定我的一切都正確。你能否爲我檢查一下。它給了我在控制檯這個錯誤：「未捕獲錯誤：0值不是函數（從另一種語言翻譯）正確」

function map_load() { 
    var draw; 

    var coords = Array(23.078412614088098, 57.33448100333726, 
23.07858534246487, 57.33415377383744, 
23.078234950383354, 57.33415913825547, 
23.078190534420507, 57.334582927279826, 
23.07792403833525, 57.3352266574434); 

    var s = -2; 
    var triangleCoords = []; 
    var coords_num = coords.length/2; 

    for (i = 0; i < coords_num ; i++) { 
     s += 2; 
     triangleCoords[i] = google.maps.LatLng(coords[s],coords[s+1]); 
    } 

    var center1 = google.maps.LatLng(coords[0], coords[1]); 

if (coords.length > 1) { 
    draw = new google.maps.Polygon({ 
     paths: triangleCoords, 
     strokeColor: "#FF0000", 
     strokeOpacity: 0.8, 
     strokeWeight: 2, 
     fillColor: "#FF0000", 
     fillOpacity: 0.35 
    }); 
} else { 
    draw = new google.maps.Marker({ 
     position: triangleCoords, 
     title:"your item location" 
    }); 
} 

    var myOptions = { 
     zoom: 16, 
     center: center1, 
     panControl:false, 
     streetViewControl:false, 
     mapTypeId: google.maps.MapTypeId.HYBRID 
    }; 

    var map = new google.maps.Map(document.getElementById("map"), myOptions); 
    draw.setMap(map); 
}

你犯同樣的錯誤兩次，缺少‘新’構造您的LatLng對象。

triangleCoords[i] = google.maps.LatLng(coords[s],coords[s+1]); 

應該

triangleCoords[i] = new google.maps.LatLng(coords[s],coords[s+1]); 

在中心1

var center1 = google.maps.LatLng(coords[0], coords[1]); 

也恰好應

var center1 = new google.maps.LatLng(coords[0], coords[1]);
