Checking at least a single White space

Question

How can I detect if an input field has at least one white space?

This is what I tried

if( $('#myVal').val().indexOf(' ') != 0 ){
     ///has at least a single white space within the string
}

Answer 1

This will do it

/\s/.test($('#myVal').val())

Answer 2

You must compare indexOf to -1 not 0

if( $('#myVal').val().indexOf(' ') != -1 ){
     ///has at least a single white space within the string
}

Here is the DEMO
