[squeak-dev] [Q] How to force Web Browser to refresh Squeak world

Fri Feb 5 13:59:56 UTC 2010

Hi:

I using this as html response

<HTML>
 <HEAD>
 <TITLE>Squeak's Screen</TITLE>
 </HEAD>

 <BODY>
<form>

Button: 
 <br>
 <input type="radio" name="button" value="4" checked>Red
 <input type="radio" name="button" value="1">Yellow
 <input type="radio" name="button" value="2">Blue
 <input type="radio" name="button" value="3">Move
 <input type="radio" name="button" value="6">Position
 <input type="radio" name="button" value="5">Text:
 <input size="30" maxlength="100" type="text" name="textIn" value="Input
this Text"> 
 <br>
 <input type=image name=point src= /screen
<view-source:http://localhost:8088/screen>  ">

 </form>
 </BODY>
 </HTML>

Works, but not refresh Web Browser.

If I add

<meta http-equiv="Refresh" content="5" >
Works , but the flicker is bad

    <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="EXPIRES" CONTENT="1 Jan 1900 00:00:00 GMT">

Don¹t seems work.

If I try:

<script type="text/javascript"><!--
   function abc(){
    alert("Hello.");
   }

   if(document.getElementsByTagName) onload = function(){
    document.getElementsByTagName("BODY")[0].onclick = abc;
  }
  //--></script>

The alert works, but Squeak do not process the event.

Any advice how to do this ?
