javascript - 比较字符串中的单词

Question

我正在尝试比较字符串中的单词。这就是我想做的:

var string1 = "Action, Adventure, Comedy";
var string2 = "Action Horror";

if (string1 have a word from string 2 == true)
{
    alert("found!");
}

我尝试过 match()，但在我的情况下，它尝试查找“Action Horror”而不是“Action”和“Horror”词。

Answer 1

您可以使用 match() 执行类似的操作 和 reduce()

var string1 = "Action, Adventure, Comedy";
var string2 = "action Horror";

var strArr = string1.match(/\b\w+?\b/g)
  //getting all words from string one
  .map(function(v) {
    return v.toLowerCase();
  });
//converting strings to lower case for ignoring case

var res = string2.match(/\b\w+?\b/g)
  // getting words from second string
  .reduce(function(a, b) {
    return a || strArr.indexOf(b.toLowerCase()) != -1;
    //checking string in first word  array
  }, false);
  // also set initial value as false since no strings are matched now

console.log(res);

或者

var string1 = "Action, Adventure, Comedy";
var string2 = "action Horror";

var res = string2.match(/\b\w+?\b/g)
  // getting words from second string
  .reduce(function(a, b) {
    return a || new RegExp('\\b' + b + '\\b', 'i').test(string1);
    //checking string in first string
  }, false);
  // also set initial value as false since no strings are matched now

console.log(res);
