问题描述

我想这样做的硒：
var变量。=编辑;
如果（typeof运算（变量）==未定义）{};
但我不完全知道如何与getEval（）方法做到这一点。

I want to do this in selenium: var variable = editors; if (typeof(variable) == "undefined") {}; but I am not entirely sure how to do it with the getEval() method.

推荐答案

既然你没有提到的地方编辑就要从我会认为这是在页面上。 VAR赢= this.browserbot.getUserWindow（）; 会给你访问窗口

Since you have not mentioned where editors is coming from I am going to assume that it is on the page. var win = this.browserbot.getUserWindow(); will give you access to window.

selenium.getEval（VAR赢= this.browserbot.getUserWindow（）; var变量。= win.editors; typeof运算（变量）===未定义;）;

browserbot是硒使用以控制浏览器的内部的JavaScript对象。它是控制窗口的对象。您可以在硒做些什么，你可以做BrowserMob。因此，进入你的脚本的高级脚本，然后把

browserbot is the JavaScript object that Selenium uses to control the internals of the browser. It is the object that controls the window. What you can do in Selenium you can do in BrowserMob. So go into the advanced scripting of your script and then put

 var resultFromEval = selenium.getEval("var win = this.browserbot.getUserWindow();var variable = win.editors; typeof ( variable) === 'undefined';");
