How to get part of string using javascript?

I have an array with one element

ClickMeArray[0] = "ClickMe=a-6,a-7,a-8,a-9,"

I want variable to return elements after ClickMe= from ClickMeArray .

Output should be a-6,a-7,a-8,a-9, .

ClickMeArray[0].split('ClickMe=')[1];

Try This

var val = "ClickMe=a-6,a-7,a-8,a-9,"; 
var myString = val.substr(val.indexOf("=") + 1);

There are many way to do this work. One way is using .replace() . You can replace ClickMe= with empty to getting another part of string.

 var ClickMeArray = "ClickMe=a-6,a-7,a-8,a-9,"; console.log(ClickMeArray.replace('ClickMe=',''));
