javascript - 使用谷歌地图 API 填充经度和纬度

我有以下 html 和 javascript。 JavaScript 将位置详细信息从 google map api 填充到 html 表单字段。这个想法是有人输入第一个 html 表单字段中填充的原始位置,然后输入第二个表单中填充的第二个位置。这非常有效。

现在我还想用第一个和第二个位置的经度和纬度填充表单。

代码填充所有必填字段,但不填充经度和纬度。有解决办法吗?

最佳答案

您没有任何代码来填充纬度和经度字段。将其添加到 fillInAddress:

document.getElementById('latitude'+unique).value = place.geometry.location.lat();
document.getElementById('longitude'+unique).value = place.geometry.location.lng();

功能齐全:

function fillInAddress(autocomplete, unique) {
// Get the place details from the autocomplete object.
var place = autocomplete.getPlace();

for (var component in componentForm) {
if (!!document.getElementById(component + unique)) {
document.getElementById(component + unique).value = '';
document.getElementById(component + unique).disabled = false;
}
}

// Get each component of the address from the place details
// and fill the corresponding field on the form.
for (var i = 0; i < place.address_components.length; i++) {
var addressType = place.address_components[i].types[0];
if (componentForm[addressType] && document.getElementById(addressType + unique)) {
var val = place.address_components[i][componentForm[addressType]];
document.getElementById(addressType + unique).value = val;
}
}
document.getElementById('latitude'+unique).value = place.geometry.location.lat();
document.getElementById('longitude'+unique).value = place.geometry.location.lng();
}
