calling a file jQuery file from html page

Question

I created some test code that uses Ajax to refresh/update two fields. It works great and now, to keep things neat, I have created a file called Ajax.js

In my HTML page where all my fields are, I would like to call this file and make it update the two variables.

I did the following:

In my HTML page:

  <--- included the meta lines needed for the Ajax file ---->
  <--- included: my jQuery includes needed ---------->
  <---- my link to the Ajax.js file -------------->
 <script src="Ajax.js"></script>

 <----- made the call this way, I am not sure is right ------->
 <!----- Ajax Update Fields Function ----->
 <script>
   jQuery('nav').Ajax();
 </script>

The call doesn't work, it doesn't update the fields. Here is the actual Ajax.js code:

// JavaScript Document
<script src="http://code.jquery.com/jquery-1.10.2.js"></script> 


$(function()
{
  setInterval(function()
   {
$.get("ajax_v00.html",function(data,textStatus, jqXHR)
 {
  var temperature=$(data).filter('#variable1').text()
  var time=$(data).filter('#variable2').text()
  $('#variable1').text(temperature)
  $('#variable2').text(time)
 })
 .fail(function(jqxhr,textStatus,errorThrown) //Callback failed
  {
   $('#errors').text("Errors:" + textStatus + " " + errorThrown)
  })
 .done(function() //Callback succeeded
  {
   $('#errors').text('Errors:');
  })
   },1000);
})

How can I call this properly? Hopefully, I explained myself correctly?

Answer 1

Put this in the head of your html page...

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="Ajax.js"></script>

Remove the script tags from Ajax.js .

Remove jQuery('nav').Ajax(); You don't need this. It's looking for a jQuery function called Ajax() , which does not exist. Your code in Ajax.js will already run when the page is loaded as you have wrapped it in the shorthand version of document.ready ...

$(function() {
    setInterval(function() {
        $.get("ajax_v00.html",function(data,textStatus, jqXHR) {
            var temperature=$(data).filter('#variable1').text();
            var time=$(data).filter('#variable2').text();
            $('#variable1').text(temperature);
            $('#variable2').text(time);
        })
        .fail(function(jqxhr,textStatus,errorThrown) {
            $('#errors').text("Errors:" + textStatus + " " + errorThrown);
        })
        .done(function() {
            $('#errors').text('Errors:');
        })
    },1000);
});

Please use this script.

   <script>
    $(document).ready(function() {
                      jQuery('nav').Ajax();});
  </script>
