Question

我已经成功设置了jQuery和Velocity的后备，但我不知道如何使用Velocity UI做同样的事情。我可以访问

name := "slickCodeGen"

version := "1.0"

scalaVersion := "2.11.6"

scalacOptions := Seq("-unchecked", "-deprecation", "-encoding", "utf8")

libraryDependencies ++= Seq(
  "com.typesafe.slick" %% "slick" % "3.0.3",
  "com.typesafe.slick" %% "slick-codegen" % "3.0.3",
  "org.postgresql" %  "postgresql" % "9.4-1201-jdbc41",
  "com.zaxxer" % "HikariCP" % "2.3.2",
  "org.scalatest" %% "scalatest" % "2.2.4" % "test"
)

slick <<= slickCodeGenTask

sourceGenerators in Compile <+= slickCodeGenTask

lazy val slick = TaskKey[Seq[File]]("gen-tables")
lazy val slickCodeGenTask = (sourceManaged, dependencyClasspath in Compile, runner in Compile, streams) map { (dir, cp, r, s) =>
  val outputDir = (dir / "main/slick").getPath
  val username = "postgres"
  val password = "xxx"
  val url = "jdbc:postgresql://localhost:5555/testdb?searchpath=public"
  val jdbcDriver = "com.postgresql.jdbc.Driver"
  val slickDriver = "slick.driver.PostgresDriver"
  val pkg = "folder1.folder2"
  toError(r.run("slick.codegen.SourceCodeGenerator", cp.files, Array(slickDriver, jdbcDriver, url, outputDir, pkg, username, password), s.log))
  val fname = outputDir + "/folder1/folder2/" + "Tables.scala"
  Seq(file(fname))
}

看看它是否存在，如何使用Velocity UI检查相同的内容？

Answer 1

如果您查看source of velocity UI，我会看到/* Note: RegisterUI is a legacy name. */评论。

因此，请使用window.jQuery.Velocity.RegisterUI检查它是否存在。

结果在控制台中：undefined。
