How to use NPAPI to read HTML params

[drama22]

Hi, i asked this question in multiable forums and on stack but with no luck with solve of the problem , hope to find solve here .

i been working with my activex and i usually can read embedded params with creating read and write property with the inside type library , but when i use NPAPI plugin i normally cant read html params because i cannot use the same library type of my normal activex inside Npapi dll project , how exactly i can read the HTML params this part are very missing for me , source of Yury Sidorov that you can download from here NPAPI plugin framework with scripting support + demo by Yury Sidorov
shows how to use java script to set value from html form to the embedded project , i maybe much stupid to figure our how to do the same thing to be able to read params like this :

Code:

<embed type="application/x-Test-plugin" width="900" height="500"> 
 <param name="name" value="albert" />
 <param name="password" value="123456" />
 </embed>

i really need help with this i been also asking this question in delphipages with no luck with answers .
