如何使用zombie.js激活javascript链接

我想让zombie.js激活一个使用javascript的链接.我正在测试它的页面是:

 <html>
  <body>
  <div id="test123">
  START_TEXT
  </div>
  <a href="javascript:go()">GO</a><br/>
  <script type="text/javascript">
  go = function() {
  var el = document.getElementById("test123");
  el.innerHTML = "CHANGED";
  }
  </script>
  </body>
  </html>

我使用的脚本是:

var zombie = require("zombie");
var browser = new zombie.Browser;

browser.visit( "http://localhost:8000/testpage.html",
        function() {
                browser.clickLink("GO", function(e, browser, status) {
                        var temp = browser.text("div#test123");
                        console.log("content:", temp);
                  });
});

我收到错误消息:

        throw e; // process.nextTick error, or 'error' event on first tick
              ^

我用的时候

browser.evaluate("go()")

有用.我错过了什么？

Zombie.js不会在href上处理带有"javascript:"的链接(在撰写本文时).

我通过在源代码中添加3行来修复它.查找/node_modules/zombie/lib/zombie/history.coffee并添加用FIX注释的3行(请注意,在.coffee中你必须尊重缩进,即使用2个空格):

# Location uses this to move to a new URL.
_assign: (url)->
  url = @_resolve(url)

  # FIX: support for javascript: protocol href
  if url.indexOf("javascript:")==0
    @_browser.evaluate(url.substr("javascript:".length))
    return

  was = @_stack[@_index]?.url # before we destroy stack
  @_stack = @_stack[0..@_index]
  @_stack[++@_index] = new Entry(this, url)
  @_pageChanged was

我可能应该在github.com上分叉zombie.js并将其放入Pull请求中,但在此之前,欢迎您使用此代码段,或者在我之前提出拉取请求.
