Matching variable in JavaScript

Question

The following code snippet should display an alert if x variable have text "I have right text right here" but my code does not work. Why?

var x = "Im the variable and I have right text right here";

if ("x:contains("I have right text right here").lenght > 0") {
  alert("Match")
}

Please look for string concatenation in javascript. You are missing a very small but very important thing there. — Akshay Khandelwal, Aug 14 '16 at 12:10

The indexOf() method returns the position of the first occurrence of a specified value in a string.

var x = "Im the variable and I have right text right here";

if ( x.indexOf("I have right text right here")  > 0 ) {
  alert("Match")
}

You may use includes:

    var x = "Im the variable and I have right text right here";

    if ( x.includes("I have right text right here")) {
        alert("Match")
    }
