This usually happens because you are loading an HTML document as a script. This is often caused by <script src=""></script>(i.e. a relative URI pointing at the current, HTML, document)) or one of the scripts pointing to a 404 error.
这通常是因为您将 HTML 文档作为脚本加载。这通常是由 <script src=""></script>（即指向当前、HTML、文档的相对 URI））或指向 404 错误的脚本之一引起的。

DOCTYPE normally is expressed on one line like below. and can cause syntax error
DOCTYPE 通常用如下一行表示。并可能导致语法错误
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
But even sometimes it will yell about a syntax error when a src attribute is not declared for an element. Firebug can also through this error when a source is not found or is called twice on one page. EX: script/image/link.
但即使有时它会在未为元素声明 src 属性时大喊语法错误。当找不到源或在一页上调用两次时，Firebug 也可以通过此错误。例如：脚本/图像/链接。
