Can not get id from dhtmlxCombo filtering mode

How can we get id from dhtmlxCombo filtering mode? i want to use it but i dont know how to get
the id from it for use with another page php.

You can use getActualValue() method to get the combo value:

var value = combo.getActualValue();

<link rel="STYLESHEET" type="text/css" href="../../codebase/dhtmlxcombo.css">

<script  src="../../codebase/dhtmlxcommon.js"></script>
<script  src="../../codebase/dhtmlxcombo.js"></script>

From select box

			<select style='width:200px;'  id="combo_zone1" name="alfa1">
				<option value="1">a00</option>
				<option value="2">a01</option>
				<option value="3">a02</option>
				<option value="4">a10</option>
				<option value="5">a11</option>
				<option value="6">a12</option>
				<option value="7">b00</option>
				<option value="8">b01</option>
				<option value="9">b02</option>
				<option value="10">b10</option>
				<option value="11">b11</option>
				<option value="12">b12</option>
				<option value="13">a22</option>
				<option value="14">a31</option>
				<option value="15">a04</option>

	var z=dhtmlXComboFromSelect("combo_zone1");


I want to get value (id) form it but i cant do. So how can i get? If you have code of autocomplelet filtering that easily to understand, can you show me?

Its a bit late but you use .getSelectedValue()
