解决方法
type="text/javascript"This attribute is optional. Since
Netscape 2,the default programming
language in all browsers has been
JavaScript. In XHTML,this attribute
is @R_502_103@ and unnecessary. In HTML,
it is better to leave it out. The
browser knows what to do.
W3C did not adopt the
language
attribute,favoring instead atype
attribute which takes a MIME type.
Unfortunately,the MIME type was not
standardized,so it is sometimes
"text/javascript"or
"application/ecmascript"or something
else. Fortunately,all browsers will
always choose JavaScript as the
default programming language,so it is
always best to simply write<script>.
It is smallest,and it works on the
most browsers.
仅为娱乐目的，我试用了以下五个脚本
<script type="application/ecmascript">alert("1");</script>
<script type="text/javascript">alert("2");</script>
<script type="baloney">alert("3");</script>
<script type="">alert("4");</script>
<script >alert("5");</script>
在Chrome上，所有脚本3(type =“baloney”)都工作。 IE8没有运行脚本1(type =“application / ecmascript”)或脚本3.基于我的两个浏览器的非广泛的示例，它看起来像你可以安全地忽略type属性，但它使用它你最好使用一个法律(依赖浏览器)值。
