js动态绑定

Question

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: '<div id="infowindow_detail" class="infowindow"><div><span>姓名：</span>'+nameId+'</div><p>'+contId+'</p></div>',
                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 <provinces[0]['subDistricts'].length; i++) {
    //console.log(i);
        var newlnglat = provinces[0]['subDistricts'][i]['center'].split(',');
        var safelevel = provinces[0]['subDistricts'][i]['level'];
        var webdress;
         
        var nameId=provinces[0]["subDistricts"][i]["name"];
        var contId=provinces[0]['subDistricts'][i]["intro"];
        if (safelevel>=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='<div class="infowindow"><div class="clearfix"><span class="spanone fl">姓名：</span>'+nameId+'<span class="spantwo fr">详情</span></div><p>'+contId+'</p></div>';
        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');
    })

用循环不行啊，你直接在donready里面写。
假设，你要绑定的元素是a，它的上一级元素是parent,要绑定的函数是func，事件类型click.那么，$(parent).on('a','click',func)
把这个写进domready里面，你再试试
