点击链接时，JavaScript代码不会执行

标签： javascript html

下面的代码应该允许我单击文本链接并启动我的javascript函数。但是，当我点击链接时，我没有反应。 我使用本教程来帮助我http://www.thesitewizard.com/archive/textsubmit.shtml

是语法错误吗？

编辑：当我点击链接时，出现此错误： 未捕获的TypeError：document.Results.getElementByID不是函数

答案 0 :(得分：2)

首先，尝试使用浏览器中的开发人员控制台（可能显示为＆＃34; Ctrl + Shift + I＆＃34;）。

对于这个问题：Javascript区分大小写，因此您的＆＃34; getElementByID（）＆＃34;不上班;使用＆＃34; getElementById（）＆＃34;代替。此外，它在调用document。[form] .getElementById（）时不会工作，你应该直接调用它：document.getElementById（id）。不过，您的HTML中没有设置ID，因此点击次数将始终返回＆＃39; null＆＃39;对于函数中的此参数。

我建议您首先尝试一些更简单的示例，然后再回到这个特定的示例！

将script标记移至form的末尾。 JavaScript来自HTML。
