Javascript 在HTML中将google地图点的坐标提取到google图纸
第一个问题,我开始学习HTML/JS,我在提取用户放置的标记的坐标并将其放入电子表格时遇到了问题。 目前,HTML文档分为两部分。一个是带有点的地图,显示纵横比和其他信息。另一部分是一个表单,要求用户输入lat/long坐标和描述。这会自动提交到谷歌问卷中,然后再提交到谷歌工作表中 我想做的是在地图上提交点的坐标,而不是让用户自己做Javascript 在HTML中将google地图点的坐标提取到google图纸,javascript,html,google-maps,google-maps-api-3,Javascript,Html,Google Maps,Google Maps Api 3,第一个问题,我开始学习HTML/JS,我在提取用户放置的标记的坐标并将其放入电子表格时遇到了问题。 目前,HTML文档分为两部分。一个是带有点的地图,显示纵横比和其他信息。另一部分是一个表单,要求用户输入lat/long坐标和描述。这会自动提交到谷歌问卷中,然后再提交到谷歌工作表中 我想做的是在地图上提交点的坐标,而不是让用户自己做 function postContactToGoogle() { var latitude=document.getElementById(

$.ajax({

});
}
在HTML中,脚本如下所示:
<b>Latitude</b>
<div id="pointLat"></div>
<b>Longitude</b>
<div id="pointLng"></div>
当作为网站运行时,上述两个功能用于在地图中显示标记的当前lat和long。但当我尝试将这些坐标导出到谷歌工作表时,它显示为空白。发生什么事了

未捕获类型错误:非法调用
点击提交后。所以在ajax函数中添加cache:false、processData:false、
function postContactToGoogle() {
var frmdata = $('#formRequest').serialize();

检查此项并注释是否存在任何错误
更新:
我用表单id更新了表单,并用与输入字段名匹配的名称更新了输入字段。对于ajaxpost,我将序列化表单输入值以作为数据发布
