[javascript] 문자열 비교 자바 스크립트 반환 가능성 %

두 문자열을 비교하고 비슷할 가능성을 반환 할 수있는 JavaScript 함수를 찾고 있습니다. 나는 soundex를 보았지만 여러 단어로 된 문자열이나 이름이 아닌 경우에는별로 좋지 않습니다. 다음과 같은 기능을 찾고 있습니다.

function compare(strA,strB){

}

compare("Apples","apple") = Some X Percentage.

이 함수는 숫자, 여러 단어 값 및 이름을 포함하여 모든 유형의 문자열에서 작동합니다. 제가 사용할 수있는 간단한 알고리즘이 있을까요?

Ultimately none of these served my purpose so I used this:

 function compare(c, u) {
        var incept = false;
        var ca = c.split(",");
        u = clean(u);
        //ca = correct answer array (Collection of all correct answer)
        //caa = a single correct answer word array (collection of words of a single correct answer)
        //u = array of user answer words cleaned using custom clean function
        for (var z = 0; z < ca.length; z++) {
            caa = $.trim(ca[z]).split(" ");
            var pc = 0;
            for (var x = 0; x < caa.length; x++) {
                for (var y = 0; y < u.length; y++) {
                    if (soundex(u[y]) != null && soundex(caa[x]) != null) {
                        if (soundex(u[y]) == soundex(caa[x])) {
                            pc = pc + 1;
                        }
                    }
                    else {
                        if (u[y].indexOf(caa[x]) > -1) {
                            pc = pc + 1;
                        }
                    }
                }
            }
            if ((pc / caa.length) > 0.5) {
                return true;
            }
        }
        return false;
    }
