How to define 'contains' in an IF conditions

[JLeong]

HI Guys,

Quick question, what is the operator for 'contains'?

My condition is: if category contains 'Europe'

How do I translate that?

I tried - if(categoryLikeEurope), it didnt work.

Thank you!

Hi,

you have to use the function indexOf.

Please check below an example:

var str = "Hello world, welcome to the universe.";
var n = str.indexOf("welcome");

JavaScript String indexOf() Method

Check also the example in the thread below, it will help you to understand how to use the indexOf in an IF condition:

Just to expand on what Alberto has said; indexOf will return a number value indicating where in a given string your syntax is located. This is 0 numbered so in the string 'Hello World' indexOf('Hello') would return 0 as the syntax appears at the start of the string. It will return -1 if the syntax is not found.

If you want to use indexOf in an if statement you will need use an operator to define if the syntax is there or not eg:

if(str.indexOf('Hello') > -1){ //if the returned value is greater than -1 then the syntax exists in the string.

//do stuff

}
