/**
 * Generic function that return javascript to add to a page to transform a common input field into an autocomplete field by calling an Ajax page (ex: /societe/ajax/ajaxcompanies.php).
 * The HTML field must be an input text with id=search_$htmlname.
 * This use the jQuery "autocomplete" function. If we want to use the select2, we must also convert the input into select on funcntions that call this method.
 *
 * @param string	$selected 			Preselected value
 * @param string	$htmlname 			HTML name of input field
 * @param string	$url 				Ajax Url to call for request: /path/page.php. Must return a json array ('key'=>id, 'value'=>String shown into input field once selected, 'label'=>String shown into combo list)
 * @param string	$urloption			More parameters on URL request
 * @param int		$minLength			Minimum number of chars to trigger that Ajax search
 * @param int		$autoselect			Automatic selection if just one value (trigger("change") on field is done if search return only 1 result)
 * @param array		$ajaxoptions		Multiple options array
 *                                      - Ex: array('update'=>array('field1','field2'...)) will reset field1 and field2 once select done
 *                                      - Ex: array('disabled'=> )
 *                                      - Ex: array('show'=> )
 *                                      - Ex: array('update_textarea'=> )
 *                                      - Ex: array('option_disabled'=> id to disable and warning to show if we select a disabled value (this is possible when using autocomplete ajax)
 * @param string	$moreparams			More params provided to ajax call
 * @return string   					Script
