Are there just two forms?

if ((pr[i].lastIndexOf("ll=", 0)!==-1) || (pr[i].lastIndexOf("m=", 0)!==-1) || (pr[i].lastIndexOf("a=", 0)!==-1))

and

if (pr[i].lastIndexOf("x=", 0)!==-1)

Or did you mean that the generic pattern is

if (p.one||p.two||p.three||et cetera at random)
...
if ((pr[i].lastIndexOf("one=", 0)!==-1) || (pr[i].lastIndexOf("two=", 0)!==-1) || (pr[i].lastIndexOf("three=", 0)!==-1) || et cetera for any number of p.thingies)

?
Makes a big difference to the question.
