javascript - 比较 Javascript 中的字符串

Question

我需要比较标题(由很多单词组成)并附上一份脏话 list 。就一个词而言，indexOf 工作得很好。但当脏话很多的时候就不行了。

谁能帮忙解决这个问题吗？

var title = "This is my title";
var badwordlist = title.indexOf('fword and other bad words list');
//var badwordlist = title.indexOf('fword');

if ( badwordlist >= 0){
//do something 
}

Answer 1

我觉得到目前为止发布的两个答案有些过分

var title = "fword This is a f**king title.",
  words = title.split(" "),
  badwords = ["fword", "f**king"];

// one of these should do it    

var isGood = words.filter(function(a) {
  return badwords.indexOf(a) == -1;
});

var isBad = words.filter(function(a) {
  return badwords.indexOf(a) != -1;
});

console.log(isBad, isGood);

// if isBad.length>0 then there were swear words in the title
