<input name="button" type="button" onclick="openy()" value="点击我" /> <script> function openy(){ var his = confirm("是否进入"); if(his==true){ var bottyr = prompt("请输入正确的网址:"); if(bottyr){ window.open(bottyr,'_blank'); }else{ window.open('https://www.imooc.com/code/412','_blank'); } }else{ document.write("谢谢光临"); } } </script> 随便输入正确网址，然后就可以直接跳过去了。
按题目的话自己改成默认网址，然后条件改成
(bottyr == "")
