c# - Selenium 异常 : "return not in a function"

Question

我正在用 C#.Net 编写 Selenium 测试脚本，但我一直遇到这个异常 -

ERROR: Threw an exception: return not in function

这是我抛出错误的代码行 -

string code = selenium.GetEval(
   "var win = this.browserbot.getUserWindow(); "+
   "return win.editAreaLoader.GetValue(win.loadedCodeEditorID);"
);

任何人都可以建议为什么会出现异常以及从 GetValue javascript 函数获取返回值的最佳方法是什么？

谢谢，

来自selenium documentation对于 GetEval:

Gets the result of evaluating the specified JavaScript snippet. The snippet may have multiple lines, but only the result of the last line will be returned.

因此，您只需要取消return:

string code = selenium.GetEval(
   "var win = this.browserbot.getUserWindow(); "+
   "win.editAreaLoader.GetValue(win.loadedCodeEditorID);"
);
