Show and Hide DIV based on users input

Question

I have an input box for zip code entry's, when a user inputs a zip code I want to show a specific DIV.

It starts with everything hidden except for the input box and go button, then the user enters a zip code and the matching DIV shows (the DIV ID will be the zip code) There maybe hundreds of DIVs and possible inputs.

Here is what I have so far, note it starts showing everything (not what I want) but it kinda works

$(document).ready(function(){
    $("#buttontest").click(function(){

        if ($('#full_day').val() == 60538) {   

            $("#60538").show("fast"); //Slide Down Effect
            $("#60504").hide("fast");
        }

         else {
            $("#60538").hide("fast");    //Slide Up Effect
            $("#60504").show("500");
        }

         });
    $("#full_day").change(function() {
        $("#60504").hide("500");
        $("#60538").show("500");
    });


});

Answer 1

jsFiddle Demo

Using pure numbers as id's is what was causing the issue. I would suggest you change them to

<div id="zip60538">
   Welcome to Montgomery
</div>
<div id="zip60504">
  <h1>Welcome to Aurora</h1>
</div>

In the html (as well as in the css and the js as can be seen in the linked fiddle)

This will allow them to be properly referenced in the DOM

If you had a lot of these to handle, I would probably wrap the html area in a div to localize it and then use an array to store the accepted zip codes, and make use of both of those approaches in the click event

$(document).ready(function(){
  var zipCodes = [60538,60504];
  $("#buttontest").click(function(){
   var zipIndex = zipCodes.indexOf(parseInt($("#full_day").val()));
   $("#zipMessage > div").hide("fast");
   $("#zip"+zipCodes[zipIndex]).show("fast");
  });
});

Start off with all the div's style of display: none;. On your button click simply check that a div exists with that ID, if so, hide all others (use a common class for this) and show the right one:

$("#buttontest").click(function() {
    var zip = $("#full_day").val();

    if ( $("#" + zip).length ) {
        $(".commonClassDiv").hide();
        $("#" + zip).show();
    }
});
