accessing property of npapi plugin with javascript

[drama22]

i do something like this

Code:

<embed id="object" type="application/x-plugin" width="900" height="500">
  <param name="name" value="test" />
  <param name="pass" value="blabla" />
</embed>

<script>
var control = document.getElementById('object');
function myFunction() {
control.name=document.getElementById("name").value;
}
myFunction();
</script>

i simply can insert Param name value to my application but i have to repeat

Code:

control.name=document.getElementById("name").value;

each time i want to read other param is there any way to accsess property in napapi same as normal activex do with type library ?like for each param property = its value ?
