试试这个：

  with（{mark：标记}）{
 google.maps.event.addListener（mark，'click'，function（）{
 createWindow（mark.id）; 
}）; 

 $ / code> 

一个例子演示了如何使用 code $：
$ b $ pre $ for（var i = 0; i setTimeout （function（）{console.log（i）;}，1000）;

$ / code>

以上将记录 10 $ c $对于（var i = 0; i with（），



  {foo：i}）{
 setTimeout（function（）{console.log（foo）;}，1000）; 




 $ b $ p $这将记录 0 到 9 ，这要感谢和引入一个新的范围。

JavaScript 1.7有一个更好的 let 语句，但在广泛支持之前，您可以使用与。

并使用 var 作为您的变量。

my code

// do ajax request and get JSON response

for (var i = 0; i < data.results.length; i++) {  
    result = data.results[i];
    // do stuff and create google maps marker    
    marker = new google.maps.Marker({  
        position: new google.maps.LatLng(result.lat, result.lng),   
        map: map,  
        id: result.id  
    });  
    google.maps.event.addListener(marker, 'click', function() {  
        createWindow(marker.id); //<==== this doesn't work because marker always points to the last results when this function is called
    });  

}

How to solve this?

Try this:

with ({ mark: marker }) {
    google.maps.event.addListener(mark, 'click', function() {  
        createWindow(mark.id);
    });
}

An example that demonstrates the use of with:

for (var i = 0; i < 10; i++) {
    setTimeout(function() { console.log(i); }, 1000);
}

The above will log 10 ten times.

for (var i = 0; i < 10; i++) {
    with ({ foo: i }) {
        setTimeout(function() { console.log(foo); }, 1000);
    }
}

This will log 0 to 9, as desired, thanks to with introducing a new scope.

JavaScript 1.7 has a let statement that is nicer, but until that is widely supported, you can use with.

And use var for your variables.
