我正在尝试创建各种混搭...我希望这些函数位于一个文件中，但是当我添加我的 Ajax 函数（中途）时，什么也没有显示。
我还想用 jQuery 显示它们，并且顶部函数（带有标记和信息的谷歌地图）在我添加底部函数之前都可以工作。
我应该像谷歌那样将它们添加到 (function () {} ) 中吗？ () 是什么？在 googlemap 函数的末尾？
当我在我的代码中调用我的函数时，我将如何调用 ajax 进行预览，因为在 Google 中调用了 window.onload。
我知道我可以使用 $.ready function(){} 但我只是将函数名称放在 .ready function { }
我不确定如何在一个文件中添加所有功能并使其工作。基本上
这是代码：
(function() {
//define global variables
var map, geocoder, marker, infowindow;
window.onload = function() {
//creating the map
var options = {
zoom: 5,
center: new google.maps.LatLng(53.383, -1.483),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), options);
//code for catching the form submit event goes here
//Getting the reference to the HTML form
var form = document.getElementById('addressForm');
//Catching the forms submit event
form.onsubmit = function () {
//getting the address from the text input
var address = document.getElementById('address').value;
//Making the geocode call
getAddress(address);
//Preventing the form from doing a page submit
return false;
}
}
//Function Stub
function getAddress(address) {
//Check to see if we already have a geocode object.
//If not we create one
if(!geocoder) {
geocoder = new google.maps.Geocoder();
}
//Creating the geoCoderRequest Object
var geocoderRequest = {
address: address
}
//Making the geocode request
geocoder.geocode(geocoderRequest, function (results, status) {
//Check if status is ok beofre proceeding
if (status == google.maps.GeocoderStatus.OK){
//Center the map on the returned location
map.setCenter(results[0].geometry.location);
//Check to see if already a Marker there
if (!marker){
//Create a new marker and add it to the map
marker = new google.maps.Marker({
map: map
});
}
//Setting position of the Marker to returned location
marker.setPosition(results[0].geometry.location);
//Check to see if we've already an info window
if(!infowindow) {
//Creating a new info window
infowindow = new google.maps.InfoWindow();
}
//Creating the content of the info window to the Address
//and the returned position
var content = '<strong>' + results[0].formatted_address + '</strong><br />';
content += 'Lat: ' + results[0].geometry.location.lat() + '<br />';
content += 'Lng: ' + results[0].geometry.location.lng();
//Adding the content to the info window
infowindow.setContent(content);
//Opening the infoWindow
infowindow.open(map, marker);
}
});
}
})();
// beginning of new function
var xhr = false;
var xPos, yPos;
function prev(){
var link = document.getElementByTagName("a").onmouseover = showPreview;

catch (e) { }
}
}
if (xhr) {
xhr.onreadystatechange = showContents;
xhr.open("GET", url, true);
xhr.send(null);
}
else {
alert("Sorry, but I couldn't create an XMLHttpRequest");
}
return false;
}
function showContents() {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
var outMsg = xhr.responseText;
}
else {
var outMsg = "There was a problem with the request " + xhr.status;
}
var preview = document.getElementById('preview');
preview.innerHTML = outMsg;
preview.style.top = parseInt(yPos)+2 + "px";
preview.style.left = parseInt(xPos)+2 + "px";
