Question

有人可以帮助我解决这个问题吗，我正在努力实现一个下拉选择按钮，显示一旦点击的课程的相关提供者，但是大多数课程有多个提供者（6-8）

我让所有提供者都通过变量，当我尝试连接时，它会导致空白。

有人可以帮忙，非常感谢。

Answer 1

你形成一个字符串的方式是错误的，它与单引号（＆＃39;＆＃39;）和双引号（＆＃34;＆＃34;）有关。而且，你有一个冒号（:)。修改后的行是

contactdetails.StudyP += "<a href='http://www.warwickshire.ac.uk/colleges/henley-in-arden.aspx'>Henley in Arden College</a><br>Personname<br>number<br><br>";

用这个替换你的行。

尝试将变量与联系人详细信息连接起来。
