         function callAjax(){
             sforce.connection.sessionid = '{!$Api.session_id}';
             var accountnam = document.getElementById('page:fm:accountname').value;
             var indust = document.getElementById('page:fm:accountindustry').value;

             account1.industry = indust;
             var result = sforce.connection.create([account1]);
             document.getElementById('page:fm:reslt').innerhtml = result;
         }
         </script>

Hi,

The src attribute specifies the URL of an external script file.
If you want to run the same JavaScript on several VF Pages, you should create an external JavaScript file, instead of writing the same script over and over again.
Save the script file with a .js extension, and then refer to it using the src attribute in the <script> tag.

To see the source code of the .js file, check:
https://ap1.salesforce.com/soap/ajax/36.0/connection.js

Kind Regards,
Sourav
