从后台获取的数据是数组中嵌套数组

var str = "";
for(var i=0; i<data.length; i++) {
    str +="<div class='exfansCon clearfix'>" +
    　　     "<img src='"+urllogo+data[i].HeadImage+"' alt=''>" +
            "<div class='exfansText'>" +
                  "<span>"+data[i].Name+"</span>" +
                  "<div class='cropN'></div> " +
                  "<i>粉丝：</i><em>"+data[i].fansCount+"</em>" +
                  "</div> " +
                  "<div class='myexAddAtten'>" +
                  "<span>添加 + </span>" +
             "</div>" +
           "</div> " +
           "<hr>";
 }
 $('.expertInt').html(str);
 $.each(data,function(a,b){
 　　var value="";
　　 $.each(b.alltag,function(c,d){
     　　value+= d.name;
     　　$(".cropN")[a].innerText=value;
 　　});
　});
