在liftweb中扩展一个类似jQuery的方法

先上代码，文字稍后再补！

import scala.xml.NodeSeq
 
import net.liftweb.http.js._
import net.liftweb.http.js.jquery._
 
def $(exp: String): jQuery = $(JE.Str(exp))
 
def $(exp: JsExp): jQuery = jQuery(exp)
 
case class jQuery(exp: JsExp) {
  val jq = JqJE.Jq(exp)
 
  @inline
  def value(value: JsExp) = (jq ~> JqJE.JqAttr("value", value)).cmd
 
  @inline
  def value() = (jq ~> JqJE.JqGetAttr("value")).cmd
 
  @inline
  def html(content: NodeSeq) = (jq ~> JqJE.JqHtml(content)).cmd
 
  @inline
  def html() = (jq ~> JqJE.JqHtml()).cmd
 
  @inline
  def remove() = (jq ~> JqJE.JqRemove()).cmd
 
  @inline
  def attr(key: String, value: JsExp) = (jq ~> JqJE.JqAttr(key, value)).cmd
 
  @inline
  def attr(key: String) = (jq ~> JqJE.JqGetAttr(key)).cmd
 
  @inline
  def removeAttr(key: String): JsCmd =
    (jq ~> JqRemoveAttr(key)).cmd
 
  // 更多方法实现 ................................................................
 
  case class JqRemoveAttr(key: String) extends JsExp with JsMember {
    def toJsCmd = "removeAttr(" + JE.Str(key) + ")"
  }
 
}
