下面的代码应该允许我点击一个文本链接并启动我的javascript函数。然而，当我点击链接时，我没有反应。我用这个教程帮助我http://www.thesitewizard.com/archive/textsubmit.shtml

                document.Results.dshToPrint.value = selectedField;
                document.Results.getElementByID(selectedField).disabled = false;
                document.Results.submit();
            }
        </script>

<input type = 'hidden' name = 'dshToPrint' > 
</form> 
</body></html>

这是语法错误吗？

编辑：当我点击一个链接时，我得到这个错误: Uncaught : document.Results.getElementByID不是一个函数

javascript

html

首先，尝试使用浏览器中的开发人员控制台(可能以“Ctrl+Shift+I”显示)。

对于这个问题: Javascript区分大小写，所以您的"getElementByID()“无法工作；使用"getElementById()”代替。而且，当调用document.form.getElementById()时，它将无法工作，您应该直接调用它: document.getElementById(id)。尽管如此，HTML中没有设置ID，所以单击将始终返回函数中该参数的“null”。

我建议您先尝试一些简单的例子，然后再回到这个特定的例子！

将script标记移动到form的末尾。JavaScript跟在HTML后面。
