如何HERE地圖從存儲在MySQL

我存儲在MySQL列「poligon」多邊形數據，像這樣 (lat, long)(lat,long)結構多邊形數據繪製多邊形...如何HERE地圖從存儲在MySQL

「（-6.811408423530006，110.85068956017494）（-6.811770629167109， 110.85174098610878）（ - 6.81129656585151，110.85196629166603）（ - 6.810718634097109，110.85200116038322）（ - 6.8106946645623，110.85195824503899）（ - 6.811046217619413，110.85130110383034）」

如何進入這個數據到多邊形代碼在這裏地圖JS API波紋管

如何與我的多邊形數據結構（緯度，經度）替換此數據波紋管（緯度，經度）...

new H.geo.Strip(
[52, 13, 100, 48, 2, 100, 48, 16, 100, 52, 13, 100], 'values lat lng alt' 
);

對不起，我新手

假設你是在javascript方面以字符串的形式檢索多邊形的數據，你應該可以使用簡單的字符串操作。

var latLonString="(-6.811408423530006, 110.85068956017494)(-6.811770629167109, 110.85174098610878)(-6.81129656585151, 110.85196629166603)(-6.810718634097109, 110.85200116038322)(-6.8106946645623, 110.85195824503899)(-6.811046217619413, 110.85130110383034)"; 
 
\t \t \t //to remove first '(' and last ')' 
 
\t \t \t latLonString=latLonString.substring(1,latLonString.length -2); 
 
\t \t \t // get individual coordinates 
 
\t \t \t var latLonValues=latLonString.split("\)\("); 
 
\t \t \t var finalArray=[]; 
 
\t \t \t for(i=0;i<latLonValues.length;i++){ 
 
\t \t \t \t var latLonSperated=latLonValues[i].split(","); 
 
\t \t \t \t finalArray.push(parseFloat(latLonSperated[0])); 
 
\t \t \t \t finalArray.push(parseFloat(latLonSperated[1])); 
 
\t \t \t \t // no altitude 
 
\t \t \t \t finalArray.push(0); 
 
\t \t \t } 
 
\t \t \t var polystrip1 = new H.geo.Strip(finalArray); 
 
\t \t \t var polygon1 = new H.map.Polygon(polystrip1); 
 
\t \t \t map.addObject(polygon1);
