关于javascript：比较字符串中的单词

Compare words in strings

我正在尝试比较字符串中的单词。这就是我想要做的：

1
2
3
4
5
6
7

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

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

我试过match()，但在我的情况下，它试图找到"动作恐怖"而不是"动作"和"恐怖"两个词。

你可以用match()和reduce()来做类似的事情。

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);

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);

具有String.split、String.indexOf和Array.foreach功能的解决方案：

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

var str1_arr = string1.split(', ');
str1_arr.forEach(function (v) {
if (string2.indexOf(v) !== -1) {
console.log("string '"+ v +"'(from string1) was found in string2 in position" + string2.indexOf(v));
}
});

// the output:
string 'Action'(from string1) was found in string2 in position 0
string 'Horror'(from string1) was found in string2 in position 7

声明两组：

1	var Set set1,ser2;

。

将string1复制到set1，将string2复制到set2

(不知道怎么做)。然后有：

var交集=新集合([x表示(集合1的x)如果(集合2.has(x))]))；

1	if intersection.prototype.size>0

两个字符串(和集合)都有共同的词。
