Question

Javascript code does not work in Firefox

Answer 1

+6 A:

Try this

{ alert(); document.getElementById('FormSignIn').submit(); }

https://developer.mozilla.org/en/DOM/document.getElementById

+1, but document.FormSignIn references a form with name='FormSignIn', whereas getElementById() will of course look for an id='FormSignIn'. This is right, but he may also need to change the html.

Right.. I make an assumption based on the limited info.. Indeed.

Oi.. <img onclick='javascript: myfunction("thisImageId");'>, put your Javascript in the HEAD

Since this question has completely changed, I shall bow out. I believe [Chetan] has the solution. Ask yourself.. What am I trying to ALERT(?)?

Answer 2

+2 A:

You need to pass an argument to alert. Seems firefox doesn't like it when you don't while IE shows a blank alert.

alert("text here");

hi tks, this is working.But i try to pass value to the document, document.getElementById("para1").innerText="text here"; this is not working

Alex 2009-08-20 17:12:37

innerText isn't supported by Firefox. Use innerHTML.

Chetan Sastry 2009-08-20 17:17:45

in each element in firefox we use "ID"? to passing and retrive values, as like xhtml?

Answer 3

+1 A:

Here is an exemple of what you should always do when validating web forms with javascript:

<html>
    <head>
     <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
     <title>New Page 1</title>
    <!-- Inline javacript should be always inside header tag -->
    <script type="text/javascript">
    function SignIn(){
     alert("");//In firefox you have to pass something to alert to make it work


     //More code logic you can put here

     //...
     //If everything is ok return TRUE to
     //post data to "somepage.aspx" if
     // dont return FALSE and do nothin
     if(everythingIsOk);
      return true;
     else
      return false; 
    }
    </script>
    </head>
    <body>
     <form method="post" action="somepage.aspx">
      <table cellpadding="0" cellspacing="0" width="311">
       <tr>
        <td height="14">
         <input type="image" src="../images/Sign_In.gif" width="80" height="28" onclick="return SignIn();">
        </td>
       </tr>
      </table>
     </form>
    </body>
</html>

document.getElementById("para1").value="text here"; this command is also not working, why?
