Class HtmlScriptConduit

java.lang.Object
  org.directwebremoting.dwrp.BaseScriptConduit
      org.directwebremoting.dwrp.HtmlScriptConduit

All Implemented Interfaces:

ScriptConduit

public class HtmlScriptConduit
extends BaseScriptConduit

A ScriptConduit for use with HTML/SCRIPT wrapped Javascript output.

Scripts begin with an html and script tags. The scripts have been altered to include an 'execute-in-parent-context' wrapper.

If this conduit is used, the output should be directed to an iframe. No polling should be required.

This conduit works with IE 6/7 since the 4k buffer drawback does not prevent the execution of script elements.
