JS中confirm弹出框

 if(confirm("确定要删除该任务吗?")){
         $.post("findTaskById.action",{taskId:taskId},function(data){
             if(data.status=='I' || data.status=='V'){
                 window.location.href = "deleteTask.action?id=" + taskId;
             } else {
                 alert("抱歉，该任务在当前状态下不可删除！");
             }
         });
     }
