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！");
            }
        });
    }
