A js random color script (used for tag pages or any pages)

I saw someone asking for this thing and sent it up. 237 bytes. Small, right?
Add the following code to <div id = "mainContent-bottomimg"> of tag. asp.
Don't ask any questions for such a simple question.
You can also add it to header. asp or footer. asp. However, all the span areas of your entire page will be in a random color.

Demo
Http://www.hljsh.com/tag.asp
The results are the same. However, my demo is implemented using asp. I am using JS. The effect is the same.
Copy codeThe Code is as follows:
<Script>
Var obj = document. getElementsByTagName ("span ");
For (I = 0; I <obj. length; I ++)
{
Var str = "0123456789 abcdef ";
Var t = "#";
For (j = 0; j <6; j ++)
{T = t + str. charAt (Math. random () * str. length );}
Obj [I]. style. color = t;
}
</Script>
