如何将参数传递给 addEventListener 侦听器函数？ [复制]

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。
显然这里有错误

new BMap.InfoWindow(pois[i].address, opts);

如何在 pois[i].marker 监听函数中使用 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());     
    });
}
