was（如何在robotframework上调用javascript）在robotframework上，如何将字符串传递给javascript生成的变量

我是个编码新手。这里我想使用robotframework，Selenium2库来测试我公司的软件。我需要模拟点击表操作，但是表的Xpath有一个问题，它是动态的，所以我需要用java脚本找到表的Xpath，然后把js生成的Xpath传递给一个变量，然后“点击元素${variable}”

但我有错误，这是回溯：

我敢猜测，您或其他人在运行测试的机器上更改了Selenium2Library的源代码。获取回溯是进行故障排除的最佳步骤。在运行测试以捕获回溯时，请使用

--loglevel DEBUG

。

您能显示完整的堆栈跟踪吗？此外，这似乎不是您的actu由于存在语法错误，您正在创建一个名为

${1111}=Execute JavaScript function getId（）的关键字{

。你可能认为你在调用javascript，但整个字符串都在robot需要一个关键字名称的地方。是的，我想调用javascript。更重要的是，我正在尝试调用javascript，因为我不知道怎么做，请原谅，我只是robotframework的学习者。这是回溯：请不要放回溯在评论中。你可以编辑你的问题并将其添加到那里。不可能将其作为评论阅读。
