How do you dereference a variable for use in a JavaScript regex?

Question

I have an array element that I wish to see if it matches the contents of an array element from a different array in JavaScript. I wish to create a pattern variable like \element 1\, where element 1 is from the first array. I could then say something like pattern.test(element 2), where element 2 is from array 2. Element 1, however, is a variable, and I want to use its contents when building the pattern variable. Can you help?

try using a loop:

var array1 = array("blue","brown","green");

var array2 = array("black","white","green");

for(i=0,i<array1.count,i++){

    for(e=0,e<array2.count,e++){

           if(array1[i] == array2[e]){

                   do this

          }

          else{

                 do this

           }

    }

}
