Assign a variable of 1 for click and 0 for unclick and then use the .click function as follows:

$(document).ready(function(){
  TriggerClick = 0;

  $("a#trigger").click(function(){
    if(TriggerClick==0){
         TriggerClick=1;
         $("div#test").animate({width:'100px'}, 500);
    }else{
         TriggerClick=0;
         $("div#test").animate({width:'300px'}, 500);
    };
  });
});

UPDATE – BETTER ANSWER

I made this suggestion awhile back; but believe there is a more elegant and pragmatic approach to solving this. You could use CSS transitions and have jquery simply add/remove a class that initiates the transition:

Working Fiddle:

CSS:

#test {
  height: 300px;
  width: 300px;
  background-color: red;

  /* setup the css transitions */
  -webkit-transition: width 1s;
  -moz-transition: width 1s;
  transition: width 1s;
}

#test.small {
   width: 100px;
}

jQuery:

$("a#trigger").on('click', function(){
    $("div#test").toggleClass('small');
});
