如何使用Java处理Selenium WebDriver中的离子范围滑块

Question

如何滑动水平滑块。我试图滚动滑块，但对我不起作用。我使用Java的代码如下：

我无法正确滑动滑块，无论输入什么值，它都会滑动到固定的pomit onlt，当前滑块值为2，并且在运行时它将滑动到3

  

请检查参考链接：   http://ionden.com/a/plugins/ion.rangeSlider/

WebElement slideFrom = driver.findElement(By.xpath("//*[@id=\"radius\"]/div[2]/div/span"));
Actions move = new Actions(driver);
move.moveToElement(slideFrom).clickAndHold().moveByOffset(370, 470).release().perform();
Thread.sleep(2000);
