It is said that can be achieved by injection of JS some function not available in the web site,

I want to in this code directly display EuropeOdds () in the value, or the link into a button, click copy EuropeOdds () in the value, or simply add a button to get the numerical can, only a little python, don't know anything about js, studied an afternoon didn't understand,
Installed, know how to injection, only owe code, search the answer on the Internet, basic it is how to change tags inside the text, not too complicated, we had an afternoon didn't succeed,
Give the master code,

# not only change the oh, is to change all of the elements,

 & lt; A href="javascript: EuropeOdds (1978330)" title="refers to the index" & gt; O & lt;/a> 

This is the original website, the website has a preloading process, before I disorderly change, seems to be injected in front of the loading, shows nothing, confused about, don't understand ah, helpless, have come to for help. Only 50 points all away!
