I would really like to provide the user some scripting capabilities, while not giving it access to the more powerful features, like altering the DOM. That is, all input/output is tunneled thru a given interface. Like a kind of restricted javacsript.
Example:
If the interface is checkanswer(func)
this are allowed:
checkanswer( function (x,y)={
return x+y;
}
but these are not allowed:
alert(1)
document.write("hello world")
eval("alert()")
