Hello, I'd like to know if you have any way to check if a String has JavaScript in it, for example, random number to trigger an event. Here's how:
abc123de45
It should be false
abc13525de
It should be true
ab12cde453fgh76i8jk9
It should be false
Thank you!
You can use it with match
var str0 = 'abc123de45'
console.log((str0.match(/[0-9]{5}/) != null));
var str1 = 'abc12345de';
console.log((str1.match(/[0-9]{5}/) != null)); You can use a function that assembles the string and uses .indexOf to check it:
function verificarSequencia(texto, quantidade) {
var regex = new RegExp('\d{' + quantidade + '}', 'g');
return regex.test(texto);
}
console.log('abc123de45', verificarSequencia('abc123de45', 5));
console.log('abc12345de', verificarSequencia('abc12345de', 5));
console.log('ab12cde345fgh67i8jk9', verificarSequencia('ab12cde345fgh67i8jk9', 5));According to this gringo OS answer :
1) indexOf - to see if the string has the other string, will return -1 if it does not have
2) (ES6) includes - use if you have ES6
var string = "foo",
substring = "oo";
string.includes(substring);
I think these are the easiest ones, I'm leaving home but then I edit with all of the answer;)
