//此示例使用自动完成功能显示地址表单
//谷歌的PlacesAPI帮助用户填写信息。
//此示例需要Places库。包括图书馆=地方
//第一次加载API时的参数。例如:
//
var placeSearch,自动完成;
变量组件形式={
街道编号:“短名称”,
路线:'long_name',
地点:'long_name',
行政区域级别1:“短名称”,
国家:'long_name',
邮政编码:“短名称”
};
函数initAutocomplete(){
//创建自动完成对象,将搜索限制为地理位置
//位置类型。
autocomplete=new google.maps.places.autocomplete(
/**@type{!HTMLInputElement}*/(document.getElementById('autocomplete'),

//当用户从下拉列表中选择地址时,填充该地址
//表单中的字段。
autocomplete.addListener('place\u changed',fillInAddress);

函数fillInAddress(){
//从自动完成对象获取位置详细信息。
var place=autocomplete.getPlace();
for(componentForm中的var组件){
document.getElementById(组件).value='';
document.getElementById(组件).disabled=false;
}
//从place details中获取地址的每个组件
//并在表单上填写相应的字段。
对于(变量i=0;i
将geologe调用用花括号括起来:onfocus=“{geologe}”
。然后在

标记上声明一个var标记=此
并将函数声明更改为tag.geologite=function(){…}
