Question

If a sentence contains “Hello World” (no quotes) then I need to return true and do something. Possible sentences could be like this:

var sentence = "This is my Hello World and I like widgets."
var sentence = "Hello World - the beginning of all"
var sentence = "Welcome to Hello World"

if ( sentence.contains('Hello World') ){
alert('Yes');
} else {
alert('No');
}

I know the .contains does not work, so I’m looking for something does work. Regex is the enemy here.

Answer 1

The method you’re looking for is indexOf (Documentation). Try the following

if (sentence.indexOf('Hello World') >= 0) { 
  alert('Yes');
} else { 
  alert('No');
}
