我有几个地址字段，其中第一个字段链接到Google Places API。因此，您开始在此框中键入地址，然后当您点击地址时，Google API会将地址拆分为其他地址字段。当用户完成此操作后，他们会单击一个按钮，动态地从表单中收集所有信息。当页面首次加载时，所有控件都是动态加载的，因此我不能使用固定值，因为可能存在这些字段未加载到页面上的实例。
当我收集数据时，从Google API填充的字段仍为空，但所有其他字段都填充了应有的字段。
这是添加click事件并管理API功能的JS：
//#region API - Add Job
$('#addJob').click(function () {
// Setup the object to pass to API
var Job = {};
$(".form__input").each(function() {
var name = this.name;
var value = this.value;
Job[name] = value;
});
console.log(Job);
// Pass Job Object to the API
});
//#endregion API - Add Job
//#region Address Auto Complete
var placeSearch, autocomplete;
var componentForm = {
street_number: 'short_name',
route: 'long_name',
locality: 'long_name',
postal_code: 'short_name'
};
function initAutocomplete() {
// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
(document.getElementById('autocomplete')),
{ types: ['geocode'] });
// When the user selects an address from the dropdown, populate the address
// fields in the form.
autocomplete.addListener('place_changed', fillInAddress);
}
function fillInAddress() {
// Get the place details from the autocomplete object.
var place = autocomplete.getPlace();
for (var component in componentForm) {
document.getElementById(component).value = '';
document.getElementById(component).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]) {
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());
});
}
}
//#endregion Address Auto Complete
这几乎与输入字段没有任何价值，但我可以看到它实际上在页面上。生成的html代码为：
<input name="CollectionAddress" class="form__input js-required" id="autocomplete" onfocus="geolocate()" type="text" placeholder="Collection Address" autocomplete="off">
<input name="CollectionAddressLine1" class="form__input js-required" id="street_number" placeholder="No.">
<input name="CollectionAddressLine2" class="form__input js-required" id="route" placeholder="Street">
<input name="CollectionAddressLine3" class="form__input js-required" id="locality" placeholder="City">
<input name="CollectionPostcode" class="form__input js-required" id="postal_code" placeholder="Postcode">
输出来自'Job'对象是：
CollectionAddress: "123 Bradwel...",
CollectionAddressLine1: "",
CollectionAddressLine2: "",
CollectionAddressLine3: "",
CollectionPostcode: ""

这很好用。点击＆＃34; addJob＆＃34;按钮，你可以得到所有的价值。
