由于 KRL 中 Web 事件的 select 语句是正则表达式，因此您可以使用以下 select 语句在查看的所有页面上触发：

select when web pageview ".*"

完整规则集上下文中的示例：

ruleset a60x425 {
  meta {
    name "test select on all pages"
    description <<
      this will select on all pageviews
    >>
    author "Mike Grace"
    logging on
  }

  dispatch { }

  rule selection_test_on_all_pages {
    select when web pageview ".*"
    {
      notify("I selected on this page!","woot!") with sticky = true;
    }
  }
}

注 1：这并不能解决调度域和浏览器扩展的问题。当从书签执行时，这将按预期工作。除非当前查看的域与调度块中设置的域匹配，否则浏览器扩展不会进入选择表达式。此示例调度域是空白的，因为我假设应用程序将从书签运行。

注 2：选择表达式被编译为正则表达式，因此请务必记住，您不需要像在使用正则表达式的语言中的其他任何地方那样对表达式使用“re//”格式。

Because the select statements for web events in KRL are regular expressions you can use the following select statement to fire on all pages viewed:

select when web pageview ".*"

Example in context of full ruleset:

ruleset a60x425 {
  meta {
    name "test select on all pages"
    description <<
      this will select on all pageviews
    >>
    author "Mike Grace"
    logging on
  }

  dispatch { }

  rule selection_test_on_all_pages {
    select when web pageview ".*"
    {
      notify("I selected on this page!","woot!") with sticky = true;
    }
  }
}

Note 1: This doesn't address the issue of dispatch domains and browser extensions. This will work as expected when executed from a bookmarklet. Browser extensions won't make it to the selection expression unless the currently viewed domain matches a domain set in the dispatch block. This examples dispatch domain is blank because I am making the assumption that the app will be run from a bookmarklet.

Note 2: Selection expressions get compiled into a regular expression so it's important to remember that you don't need to use the 're//' format for the expression like you do everywhere else in language you use a regular expression.
