推荐答案

您必须在数据库中存储特定位置的纬度和经度。

使用ajax对象li ke

use ajax object like

xmlhttp.open("Get","https://www.google.com/maps/preview?q="+placename,true)
xmlhttp.send(null)
 xmlhttp.onreadystatechange = function () {
                    if (xmlhttp1.readyState == 4 ||xmlhttp.Status="ok") {
                           var x = xmlhttp.responseText;
                            document.getElementById("iframe").innerHTML=x;
                              }
                         }

无需api以及与javascript相关的所有其他详细信息

No need of api and all other details related to javascript

您可以尝试GeoCoding API，用于将搜索到的地址转换为纬度和经度，可用于在Google地图中显示标记。检查链接。
