  • 0

I have a piece of code that is working fine in IE, but it doesn’t run in Firefox. I think the problem is that I have not been able to implement $('document').ready(function). The structure of my json is like [{“options”:”smart_exp”},{“options”:”user_intf”},{“options”:”blahblah”}].
I will be very thankful if someone can see my code & help me in correctly implementing it. Here is my code:

<html><head>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2
     /jquery.min.js"></script>
     <script type="text/javascript" language="javascript">
     $(document).ready(function() { 
     $.getJSON("http://127.0.0.1/conn_mysql.php", function (jsonData) {
     $.each(jsonData, function (i, j) {
     document.form1.fruits.options[i] = new Option(j.options);
     });});
     });
     </script></head>
     <body><form name="form1">
     My favourite fruit is :
     <select name="fruits" id="fruits" /></form></body>
</html>

    Just run $(document).ready(function() {doStuff}). This will automatically run when the document is ready.

    It’s best practice, at least in my opinion, that you don’t put any events in the html itself. This way you separate the structure of an html document from it’s behavior. Instead attach events in the $(document).ready function.

    <html>
  <head>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
     <script type="text/javascript">
       $(document).ready(function() { 
           $.getJSON("http://localhost/conn_mysql.php", function (jsonData) {
             var selectElem = $('#fruits');

             for(var i = 0; i < jsonData.length; i++) { 
               selectElem.append($('<option>').html(jsonData[i].options));
             }

           });
       });
     </script>
  </head>
  <body>
    <form name="form1">
      My favourite fruit is :
      <select name="fruits" id="fruits" />
    </form>
  </body>
</html>

    EDIT:
    I tested with the following and mocked the json object since I can’t make that call myself.

    <html>
  <head>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
     <script type="text/javascript">
       $(document).ready(function() {
           var jsonData = JSON.parse('[{"options":"smart_exp"},{"options":"user_intf"},{"options":"blahblah"}]');
           var selectElem = $('#fruits');

           for(var i = 0; i < jsonData.length; i++) { 
             selectElem.append($('<option>').html(jsonData[i].options));
           }

       });
     </script>
  </head>
  <body>
    <form name="form1">
      My favourite fruit is :
      <select name="fruits" id="fruits" />
    </form>
  </body>
</html>
