- PostDocument- the value attribute is used to specify several different parameters. Each parameter is delimited with the string ##ephox##. The following are the different parameters that can be specified through the value attribute:
Post Field
The name of the field in the HTTP POST that EditLive! for Java uses to POST its content.This parameter is required.
Post Acceptor URL

callback- Pass the entire content of th HTTP response to a specified JavaScript callback function for processing.
This parameter is required.

The parameters specified through the value attribute string must appear in the order Post Field, Post Acceptor URL, Response Processing, and JavaScript Callback Function (if needed).
Example
The following parameters specified through the value attribute string would store the contents of EditLive! in a hidden HTML form field called POST_field, sending the contents via HTTP Post to http://someserver/postacceptor.jsp, then call back the JavaScript function called JSFunction.
value="POST_field##ephox##http://someserver/postacceptor.jsp##ephox## callback##ephox##JSFunction"
When using the insertHTMLAtCursor action the HTML to be inserted must be URL encoded in the XML file. For example, <p>HTML to insert<p> becomes %3Cp%3EHTML%20to%20insert%3C/p%3E.

The toolbar button defined in this example will call the JavaScript function called eventRaised. This JavaScript function will show an alert with the text "button clicked on " with the id of the editor when then menu item is clicked.
function eventRaised(id) {
alert("button clicked on " + id);
}

value="DisplayAttributes"
enableintag="h1"
/>
</toolbar>

}
The following example demonstrates how to define a custom toolbar button which uses the PostDocument action for use within EditLive!.
