public class AjaxTextInputElementRenderer

extends BasicSearchElementRenderer

Generates a 'look-ahead' text input box using AJAX techniques. This input is linked to an IDisplayFormRenderer that is used to display temporary (dynamic) results generated by the SearchDispatcher. The DropdownDisplayFormRenderer is typically used for this purpose.

    <SearchElementRenderer 
       rendererClass="com.raritantechnologies.quickstart.taglibrary.ajax.AjaxTextInputElementRenderer"
       sourceName="[ search source used to look up dropdown data ]"
       sourceType="[ type of search source ]"
       queryField="[ source query field used for lookup ]"
       fieldID="[ field ID of the select element ]"
       dispatcherName="[ unique name of the background search dispatcher ]"
       displayFormDiv="[ optional name of div that will be loaded with intermediate results ]"
       pageSize="[ page size of display form ]"
       startRec="[ optional start rec (default = 1) ]"
       wildcardChar="[ optional trailing character for sources that use wildcard patterns ]" >

      <!-- DisplayFormRenderer - typically a specialized DropdownDisplayFormRenderer instance -->
      <DropdownDisplayFormRenderer
                              resultNameField="[ field in result that goes to option display ]"
                              resultValueField="[ field in result that goes to option value ]"
                              dropdownSize="[ number of rows in dropdown ]"
                              multipleSelect="[true|false(default)]"
                              javascriptFunction="loadMenuSelect_"
                              dropdownSelectFunction="[ optional javascript function to call on dropdown selection event ]" >
