Question

我在这个论坛上一直在阅读这个错误，但我找不到任何有用的东西。真奇怪的是我在演讲中从教师那里复制了这个，但它不会超过。有什么想法吗？

Answer 1

您错过了收尾引号：

document.write("<br> Your second Entry: "+secondInt+"<br>);

Answer 2

您在这里缺少引号：

 document.write("<br> Your second Entry: "+secondInt+"<br>);

应该是：

 document.write("<br> Your second Entry: "+secondInt+"<br>");

希望这有帮助。

Answer 3

你应该关闭双引号第4行的脚本。

document.write("<br> Your second Entry: "+secondInt+"<br>");
