It sounds like you don't need Ajax.Autocompleter, it is overkill.
However, looking at it's code I came up with this in a matter of
minutes. It's not tested but you get the idea I think. If you need any
more functionality that is included in Autocompleter but not here just
look at the code (controls.js).
Ajax.Listener = Class.create();
Ajax.Listener.prototype = {
initialize: function(element,target,page,options){
this.element = $(element);
this.target = $(target);
this.page = page;
this.options = Object.extend({
frequency: 1000,
parameters: '',
ajaxOptions: {}
},options || {}
this.observer = null;
this.onKeyPressHandler = onKeyPress.bind(this);
Event.observe(this.element, 'keypress', this.onKeyPressHandler);
},
onKeyPress: function(){
if(this.observer) clearTimeout(this.observer);
this.observer = setTimeout(this.onObserverEvent.bind(this),
this.options.frequency*1000);
},
onObserverEvent: function(){
var params = this.element.name+'='+this.element.value;
if(this.options.parameters) params += '&'+this.options.parameters;
new Ajax.Updater(this.target, this.page,
Object.extend(this.options.ajaxOptions,{
parameters: params
});
},
dispose: function(){
Event.stopObserving(this.element, 'keypress',
this.onKeyPressHandler);
}
}
<textarea id="mytext" name="userText"></textarea>
<div id="myinfoarea"></div>
<script>
new Ajax.Listener('mytext','myinfoarea','mypage.php',{
parameters: 'extraParam=extraValue'
});
</script>
The POST on server side will be:
'userText' => 'whatever they entered',
'extraParam' => 'extraValue',
'_' => ''
