测试Latex
According to this page, if we put the following code in the head of html page
<script src="http://latex.codecogs.com/latex.js" type="text/javascript"></script>
it will show you the $latex$ symbols correctly, like this,
$ T:V \rightarrow W$ ,
$v \in T $
$ T(v) = Av \in W$
----------------------------
Strangely, it does not work for the following latex sentence which is the same above buat at different locations:
$ T(v) = Av \in W$
$v \in T $
$ T(v) = Av \in W$
So after some search in the internet, I put the following in the head:
<script type="text/javascript" src="http://common.cnblogs.com/script/ASCIIMathML.js"></script>
And this works only on Firefox, sometimes on IE, but never works on the Google brower.
