我有以下的HTML和JavaScript。 JavaScript从谷歌地图API填充位置详细信息到HTML表单字段。这个想法是有人输入他们的原始位置,它填充在第一个HTML表单域中,然后输入第二个位置,该位置以第二个表单填充。这工作完美。使用谷歌地图API填充经度和纬度

现在我也想填充第一和第二位置的经度和纬度。

该代码会填充所有必填字段,但不会填充经度和纬度。任何工作?

您期望填充经度和纬度的代码在哪里? – geocodezip

@geocode一切都在共享代码中。看看html部分 – nick

没有代码来填充经度和纬度... – geocodezip

您没有任何代码来填充纬度和经度字段。这种加入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(); 
}
