This code does what I think you want:
package com.liftcode.snippet
import _root_.scala.xml.{NodeSeq, Text}
import _root_.net.liftweb.util._
import _root_.net.liftweb.common._
import com.liftcode.lib._
import Helpers._
import _root_.net.liftweb.http._
import js._
import JsCmds._
import JE._
class HelloWorld {
private def processAjaxCall(in: String): JsCmd =
SetHtml("fruit_bat", <span>The id is {in}</span>)
def howdy(in: NodeSeq): NodeSeq =
for {
i <- 1 to 20
} yield <div><a id={"id_"+i} onclick={SHtml.ajaxCall(JsRaw("this.id"),
processAjaxCall)._2.toJsCmd+"; return false;"}>Click me #{i}</a></div>
}
