我绑定了点击事件，没扔和效果什么原因，之前来帮忙的朋友在来看看

var newmarkers = []; //province见Demo引用的JS文件
var infowindow = new AMap.InfoWindow({
                isCustom: true, //使用自定义窗体
                //content: '
姓名：'+nameId+'
'+contId+'
',
                offset: new AMap.Pixel(16, -45)  
            });
function markerClick(e){
        //console.log(e.target.content);
        //alert( e.target.getPosition())
        infowindow.setContent(e.target.content);
        infowindow.open(map, e.lnglat);
        
    }
for (var i = 0; i =85) {
            webdress='http://www.haotu.net/up/1155/16/152.png';
        }else if(safelevel>=75&&safelevel<85){
            webdress='http://www.haotu.net/up/1155/16/156.png';
        }else if(safelevel==60){
            webdress='http://www.haotu.net/up/1155/16/153.png';
        }else{
            webdress='http://www.haotu.net/up/1155/16/151.png'
        }
        var newmarker = new AMap.Marker({
                position: newlnglat,
                icon: webdress,
                //offset: {x: -8,y: -34}
            });
        newmarker.content='
姓名：'+nameId+'详情
'+contId+'
';
        newmarker.on('click', markerClick);
        newmarker.emit('click', {target: newmarker}); 

        newmarkers.push(newmarker);      
        
   };
    // 添加点聚合
    function addCluster() {
        map.plugin(["AMap.MarkerClusterer"], function() {
        var cluster = new AMap.MarkerClusterer(map, newmarkers);
        });       
    };
    addCluster();
    $('.spantwo').on('click',function(){
        alert('1');
    })
