我有一个带有 if 语句流的函数。如果语句为真，它会使用 innerHTML 写回文档。在 innerHTML 中，我可以添加 p 标签和文本，但只要我添加<a href>一行，它就会给我一个“未捕获的语法错误：意外的标识符”错误。我究竟做错了什么？错误在calage()具有以下代码段的函数内：
if((calyear == 2010 && calmon > 10) || (calyear == 2011 && calmon < 11)) {
console.log("They should be in the 2YO");
document.getElementById("demo").innerHTML="<p>Your student would more than likely enter the 2YO class. The 2YO students will have class at the Nanshan campus. To apply, please fill out the following application.</p> <a href="http://qsishekou.org" target="_blank">QSI Shekou!</a>";
}
完整的 HTML 文件如下。感谢您的帮助！
