在Mechanize中单击带有JavaScript的链接 [英] Clicking link with JavaScript in Mechanize

问题描述

我有这个:

<a class="top_level_active" href="javascript:Submit('menu_home')">Account Summary</a>

我想单击该链接，但是使用link_to时出现错误.

I want to click that link but I get an error when using link_to.

我尝试过:

bot.click(page.link_with(:href => /menu_home/))
bot.click(page.link_with(:class => 'top_level_active'))
bot.click(page.link_with(:href => /Account Summary/))

我得到的错误是: NoMethodError:nil:NilClass的未定义方法"[]"

The error I get is: NoMethodError: undefined method `[]' for nil:NilClass

推荐答案

这是一个javascript链接.机械化将无法单击它，因为它不评估javascript.抱歉！

That's a javascript link. Mechanize will not be able to click it, since it does not evaluate javascript. Sorry!

尝试找出当您单击该链接时浏览器中发生的情况.是否创建POST或GET请求?发送到服务器的参数是什么.知道这一点后，您就可以在Mechanize脚本中模拟相同的操作. Chrome开发人员工具/Firebug会帮忙.

Try to find out what happens in your browser when you click that link. Does it create a POST or GET request? What are the parameters that are sent to the server. Once you know that, you can emulate the same action in your Mechanize script. Chrome dev tools / Firebug will help out.

如果这不起作用，请尝试切换到支持javascript评估的库.我已经使用 watir-webdriver 取得了巨大的成功，但是您也可以尝试 casperjs ， pjscrape 或其他工具

If that doesn't work, try switching to a library that supports javascript evaluation. I've used watir-webdriver to great success, but you could also try out phantomjs, casperjs, pjscrape, or other tools
