Question

this for loop is producing an error: Unexpected identifier, why?

$(document).ready(function(){
    $('#done').click(function(e){

       var id = [];
       id = $('.crewMember');
       for(var i=0, i<id.length, i++){
            console.log(id[i]);
       }

    });
});

Answer 1

You need to use semicolon (;) instead of comma (,) in for loop syntax:

for (var i=0; i<id.length; i++){

The unexpected identifier is because it’s expecting multiple variables to be declared/assigned, but you are doing logical comparisons and incrementing.
