Question

simple logic here, I don’t know how I can separate the value from a hash returned by window.location.hash. Something like .split('=')[0], but removing everything before it instead of everything after it.

Some potential hashes: /#work /#work=video1

I’d like to say:

var hash = window.location.hash,
    val  = hash.split('=')[0];

    if (val != ''){
        do some stuff because there IS a value
        i.e. once split, the value is something
    } else {
        do some other stuff because there IS a value
        i.e. once split, the value is nothing
    }

Answer 1

var hash = window.location.hash,
    val  = hash.substr( hash.indexOf('=') + 1 );

if(val.length) {  // val
  // do something
} else {
  // do something else
}
