Read variables from javascript in selenium

Question

I am using Selenium Webdriver 2.0. Html page being tested, includes x.js file and the variable "price" is defined in x.js based on some data entered from the html form and some calculations on the javascript. HTML prints the right value of price using: <td>$ <span id="price"></span></td> How can I catch the value of a price from the javascript?

Answer 1

假设价格显示为<span></span>内的文本，请尝试以下操作：

driver.findElement(By.id("price")).getText();
