Hi, I have 3 chained select (not sequential) and I tried to create 3 observers in order to change select contents dynamically in this way: [code] Event.observe(document.getElementById(this.searchItem1),''change'',this.updateSearchResults1.bindAsEventListener(this)); Event.observe(document.getElementById(this.searchItem2),''change'',this.updateSearchResults2.bindAsEventListener(this)); Event.observe(document.getElementById(this.searchItem3),''change'',this.updateSearchResults3.bindAsEventListener(this)); [/code] When I change the value of 1 of the 3 select the code in the function updateSearchResultsX is executed and in continues working everytime i change the value of the same select. When I try to change 1 of the other select values(after the first change) the observer doesn''t seem to work infact nothing happens. Can you please help me???? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

$F(''select1'')+''&select2=''+
$F(''select2'')
+''&select3=''+ $F(''select3'');
//var pars = this.nomeParametro + ''='' +
$F(this.searchItem);
pars+= ''&tmp=''+Math.random();
var url2 ="select2.php";
var url3 ="select3.php";
//show the activity indicator
$(this.activityItem).style.display = '''';
//make the ajax request
var myAjax = new Ajax.Request(url2,{method:
''post'',parameters:
pars,onComplete: this.handleSearch2.bind(this)});
