Question

Given two strings, how can I do something if both strings have one word in common?

For example: "foo bar" and "foo line" both have the word "foo". The strings could be 3 words long or more, like "foo bar" and "blue foo line".

What I’ve tried so far:

var m = "foo bar";
var n = "foo line";
if(m.match(/n/g)){
  alert("match");
}

better version :

var m = "foo bar".split(' ');

var n = "foo line".split(' ');
var isOk=0;

    for (var i=0;i<m.length;i++)
    {
    for (var j=0;j<n.length;j++)

    {
      var reg = new RegExp("^"+m[i]+"$", "gi");

    if (n[j].match(reg) )
    {isOk=1;break;}
    }
    }

if (isOk==1)
  alert("match");
