我的网站通过AJAX加载所有内容,其中包括我正在使用Google自动填写的地址表单。问题是谷歌的演示代码在输入字段上启动了监听器,即使它还不存在,这就是AJAX的情况。
我无法弄清楚如何将侦听器事件转移到可能autocomplete
的实际onkeyup
表单输入。
请原谅我的代码示例中粗略的AJAX替代品!
var placeSearch, autocomplete;
var componentForm = {
route: 'long_name'
};
var options = {
types: ['geocode'],
componentRestrictions: {country: "us"}
};
function initAutocomplete() {
autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')),options);
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());
});
}
}
&#13;
<div id="ajax"></div>
<a href='#' onclick='document.getElementById("ajax").innerHTML="<input class=\"form-control\" id=\"autocomplete\" placeholder=\"Enter your address...\" onFocus=\"geolocate()\" type=\"text\"><label for=\"route\"></label><input type=\"text\" id=\"route\" disabled=\"true\">";'>click me</a>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAUn3BBDhG1bXZckXyx6f2E2NSOhasl6FY&libraries=places&callback=initAutocomplete" async defer></script>

答案 0 :(得分:0)
initAutocomplete函数是Google Maps脚本网址中指定的回调(作为GET参数)
你可以这样做
function initAutocomplete() {
var el = document.getElementById('autocomplete');
if(el!=null){
autocomplete = new google.maps.places.Autocomplete(el,options);
autocomplete.addListener('place_changed', fillInAddress);
}
}
这意味着如果尚未创建元素,它将不会执行任何操作,因此您需要在创建元素的AJAX调用之后调用initAutocomplete。
