我有一个if语句流的函数。如果语句为true，则使用innerHTML写回文档。在innerHTML中我可以添加p标签和文本，但是只要我添加<a href>行，它就会给我一个“Uncaught SyntaxError：Unexpected identifier”错误。我究竟做错了什么？错误在calage()函数中，包含以下代码段：
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。谢谢你的帮助！

试试这个：
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>";
用“”包围字符串，就像你一样 - 所以使用'来包围属性。
例如：
var str = "hello, I am" gonna go" here";
会因为你关闭字符串然后你没有连接而产生错误，因此是异常。
所以，
var str = "hello, I am' gonna go' here";
是合适的。
或
var str = "hello, I am" + "gonna go here";
或者如果你必须使用双引号，则反斜杠。
var str = "hello, I am\" gonna go\" here";
答案 1 :(得分：0)
就我而言，我已经使用了简单的引号，如@jamesemanon所建议的那样，但仍然无法正常工作。在Android设备上没问题，IOS模拟器没问题，但是IOS设备失败了。
对我来说，解决方案是删除target="_blank" attr，然后在设备上进行链接。
