jquery hide() and slideDown()

$(document).ready(function(){
 $('#AddCity').hide();
 $('#AddCityA').click(function(){
     if ( AddCityVar==1 ){
         $('#AddCity').hide();
         var AddCityVar=0;
     }else{
           $('#AddCity').slideDown("slow");
           var AddCityVar=1;
     }
  });

I cant figure this out, why div with ID #AddCity is opening on first click on #AddCityA link, but never goes hide on second click? Does $('#AddCityA').click(function() work only once?

<a href="#" id="AddCityA">Add City</a> 

<div id="AddCity">
    here some code
</div>

Thanks for any help

You seem to be re-initialisng AddCityVar everytime you assign some value to it. You need to have it outside the scope of the click function :

$(document).ready(function(){
    $('#AddCity').hide();
    var AddCityVar= 0;
    $('#AddCityA').click(function(){
      if ( AddCityVar==1 ) {
         $('#AddCity').hide();
         AddCityVar=0;
      }
      else {
         $('#AddCity').slideDown("slow");
         AddCityVar=1;
      }
    });
 });

But, as roasted mentioned, it neednt have a variable to do this. You can just use slideToggle :

$('#AddCityA').click(function () {
  $('#AddCity').slideToggle("slow");
});

You could just check if the element is visible:

$(document).ready(function () {
    $('#AddCity').hide();
    $('#AddCityA').click(function () {
        var state = $('#AddCity').is(':visible');
        $('#AddCity')[state?'hide':'slideDown'](state ? 0 : 'slow');
    });
});

FIDDLE

For a much simpler approach, you could slide the element both ways :

    $('#AddCity').hide();
    $('#AddCityA').on('click', function () {
        $('#AddCity').slideToggle('slow');
    });
