Assuming you mean you want to find whether the contents of A are in B, just use the following:

var found = !(B.indexOf(A) == -1);

Javascript itself has a function for this: indexOf.

alert("blaat".indexOf('a') != -1);

You want to check if one string belongs into another? You can use regular expresions or strpos like function

function strpos( haystack, needle, offset){
    var i = (haystack+'').indexOf(needle, (offset ? offset : 0));
    return i === -1 ? false : i;
}

To my knowledge jQuery doesn't have a native function for doing what you want.
