如何将参数传递给addEventListener侦听器函数？

Question

可能重复：
Javascript closure inside loops - simple practical example
Please explain the use of JavaScript closures in loops

for (var i = 0; i < pois.length; i++) { 
    pois[i].marker.addEventListener('dblclick', function (data) { 
     var infoWindow = new BMap.InfoWindow(pois[i].address, opts); 
     map.openInfoWindow(infoWindow, map.getCenter());  
    }) 
} 

这是我的代码。
显然有在这里错误

新BMap.InfoWindow（POI的[I]。地址，选择采用）;

如何在pois [i] .marker监听器函数中使用pois [i] .address？

Answer 1

for (var i = 0; i < pois.length; i++) { 
    setupEventListener(pois[i]); 
} 

function setupEventListener(obj) { 
    var address = pois[i].address; 
    obj.marker.addEventListener('dblclick', function (data) { 
     var infoWindow = new BMap.InfoWindow(address, opts); 
     map.openInfoWindow(infoWindow, map.getCenter());  
    }); 
}
