arcgis api for js实现点击文字内容获取所对应的点高亮显示。

var name;//声明name为全局变量后面代替搜索框要传入的值
$(function(){ 
 $(‘.test2 a‘).click(function(){
  $(this).parent().each(function () {//移除其余非点中状态
         $(‘.test2 a‘).removeClass("special_color");
        });
        $(this).addClass("special_color");//给所点中的增加样式
name=$(this).text();
 })
})//获取所点击的文本值并赋给name；
