Last element in each set

Question

I have an issue  where by I am doing a simple form validation  that needs some custom stuff that the validation plugin could not do for me  Basically  I have a name  email and message field  all are required  but only email is really validated  the others just need to check if theyre not empty  Here is my current code        contactMe form   submit function         var email       requiredEmail   val        if email    0             if isValidEmailAddress email                      requiredText   each function                     thisVal     this  val                    var  this     this                   if thisVal    0                        console log  Valid Field    thisVal                       if    this       this  parent   last                              console log  Last field  submit form here                                                                      else               console log  Email Not Valid                         return false        Just to explain  I am first checking the email address is valid via the isValidEmailAddress function  which is working  Then I am going through using each    all the requiredText fields and checking if theyre not empty  When I get to the last  requiredText field  I want to submit the form using post or whatever    if    this       this  parent   last      What I have there is obviously incorrect but I am not sure what can be used to check if it is the last in the each result set  and perform an action if true    Can anybody help me out here    Thanks in advance

A shorter answer from here  adapted to this question    var arr       requiredText    arr each function index  item       var is last item    index     arr length - 1          Just for completeness

each passes into your function index and element  Check index against the length of the set and you re good to go   var set       requiredText    var length   set length  set each function index  element          thisVal     this  val          if parseInt thisVal      0              console log  Valid Field      thisVal             if  index      length - 1                   console log  Last field  submit form here

For future Googlers i ve a different approach to check if it s last element  It s similar to last lines in OP question   This directly compares elements rather than just checking index numbers    yourset each function         var  this     this       if  this 0       yourset last   0                this is the last one
