我尝试使用here中的代码自动填充地址字段。它作为一个静态HTML文件工作正常,但当我把它放在一个aspx页面时。我没有在字段上使用任何runat = server,并且在查看呈现的HTML时,ID /名称等似乎仍然没有问题。
下面是完整的代码:
<table id="address">
<tr>
<td class="label">Street address</td>
<td class="slimField"><input class="field" id="street_number"
disabled="true"></input></td>
<td class="wideField" colspan="2"><input class="field" id="route"
disabled="true"></input></td>
</tr>
<tr>
<td class="label">City</td>
<td class="wideField" colspan="3"><input class="field" id="locality"
disabled="true"></input></td>
</tr>
<tr>
<td class="label">State</td>
<td class="slimField"><input class="field"
id="administrative_area_level_1" disabled="true"></input></td>
<td class="label">Zip code</td>
<td class="wideField"><input class="field" id="postal_code"
disabled="true"></input></td>
</tr>
<tr>
<td class="label">Country</td>
<td class="wideField" colspan="3"><input class="field"
id="country" disabled="true"></input></td>
</tr>
</table>
<script>
var placeSearch, autocomplete;
var componentForm = {
street_number: 'short_name',
route: 'long_name',
locality: 'long_name',
administrative_area_level_1: 'short_name',
country: 'long_name',
postal_code: 'short_name'
};
function initAutocomplete() {
autocomplete = new google.maps.places.Autocomplete(
(document.getElementById('autocomplete')),
{types: ['geocode']});
autocomplete.addListener('place_changed', fillInAddress);
}
function fillInAddress() {
var place = autocomplete.getPlace();
for (var component in componentForm) {
document.getElementById(component).value = '';
document.getElementById(component).disabled = false;
}
for (var i = 0; i < place.address_components.length; i++) {
var addressType = place.address_components[i].types[0];
if (componentForm[addressType]) {
var val = place.address_components[i][componentForm[addressType]];
document.getElementById(addressType).value = val;
}
}
}
function geolocate() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var geolocation = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
var circle = new google.maps.Circle({
center: geolocation,
radius: position.coords.accuracy
});
autocomplete.setBounds(circle.getBounds());
});
}
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=REDACTED&libraries=places&callback=initAutocomplete"
async defer></script>
我在控制台中收到以下JS错误:
Test.aspx:470 Uncaught ReferenceError: google is not defined
然后当我点击其中一个自动完成建议时:
Test.aspx:485 Uncaught TypeError: Cannot set property 'value' of null
呈现的HTML似乎没问题,没有.net跟踪等
答案 0 :(得分:0)
首先,您需要转到https://console.developers.google.com/并选择API。
在Google Maps API中选择Google Maps JavaScript API,并确保为Google Maps JavaScript启用API。
其次,您需要创建一个API密钥:
无需指定任何引荐人
所以你应该看到保存后允许任何推荐人。
现在,您将获得一个密钥,复制该密钥并将其粘贴到
js?key = YOUR_API_KEY,来自脚本标记,使用您在YOUR_API_KEY位置获得的密钥。
