當前，當您點擊某個標記時，可點擊的獲取路線鏈接隨標題和地址一起出現。我還希望獲取路線鏈接也出現在側欄上。Google Maps API路線 - 移動路線鏈接至側邊欄

我試圖從這裏移動：
html: locations[i][0]+"<br>"+locations[i][1]+"<br><br><a href='javascript:getDirections(customerMarker.getPosition(),""+locations[i][1]+"");'>Get Directions</a>"
到這裏：
outputDiv.innerHTML += "<a href='javascript:google.maps.event.trigger(closest[" + results[i].idx_closestMark + "],\"click\");'>" + results[i].title + '</a><br>' + results[i].address + "<br>" + results[i].distance.text + ' approximately ' + results[i].duration.text + "<br><a href='javascript:getDirections(customerMarker.getPosition(),""+locations[i][1]+"");'>Get Directions</a><br><hr>"
我現在能夠有路線鏈接出現在側邊欄，但方向不匹配正確的標題和地址，就像他們在標記上做的一樣。有人知道怎麼修這個東西嗎？
您需要使用地址的「排序」版本，而不是輸入中的版本。您的問題已關閉，因此我現在無法回答，但看起來應該很快就會重新打開。 – geocodezip
