Javascript 如何使用SeleniumWebDriver测试单击SVG对象？

我试图编写一个代码来检查点击SVG对象的功能——例如，这个URL上的美国州

http://www.amcharts.com/svg-maps/?map=usa

这是可行的，但是有更好的方法吗？不移动鼠标的东西

robert = new Robot();
robert.mouseMove(x, y);
// full click once to get focus on the window
robert.mousePress(MouseEvent.BUTTON1_MASK);
robert.mouseRelease(MouseEvent.BUTTON1_MASK);
// then set the filter
robert.mousePress(MouseEvent.BUTTON1_MASK);
robert.mouseMove(x, y);
robert.mouseRelease(MouseEvent.BUTTON1_MASK);

在SVG中，显示的所有内容都是由坐标定义的块。在您的例子中，每个状态也是一个块，因此有一个XPath，您可以在Selenium代码中使用它

使用浏览器开发工具分析页面的代码，找出与要单击的状态对应的块

这是对应于加利福尼亚的元素

但是，再做两次，您将看到最后一个节点永远都不相同

//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[5]
//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[34]

因此，我们希望在

/*[@id=“chartdiv”]/div/div[1]/svg/g[7]/g/g[1]/

中找到

，属性值以

M371.75174.28l

开头。应该是这样的：

//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[starts-with(@d, "M371.75,174.28l")]

您必须自己重复所有这些步骤，因为我们可能没有生成相同的SVG

---

但因为：

• /g

  变成

  /*[name（）=“g”]

• /svg

  变成

  /*[name（）=“svg”]

• /path

  变成

  /*[name（）=“path”]

这将提供以下XPath：

//*[@id="chartdiv"]/div/div[1]/*[name()="svg"]/*[name()="g"][7]/*[name()="g"]/*[name()="g"][1]/*[name()="path"][starts-with(@d, "M371.75,174.28l")]

---

在硒中：

webDriver.findElement(
  By.xpath(
    '//*[@id="chartdiv"]/div/div[1]/*[name()="svg"]/*[name()="g"][7]/*[name()="g"]/*[name()="g"][1]/*[name()="path"][starts-with(@d, "M371.75,174.28l")]'
  )
).click();

---

title（）

专用于标记值（即

VALUE

），而

@title

专用于属性值（即

）。在您的例子中，“Montana”不是

标记的值，而是

title

标记属性的值，因此它将是

[以（@title，'Montana'）]开头]

。这将给出一个NosTouchElementException。（顺便说一句，谢谢你的帮助）。WebElement montana=driver.findElement（By.xpath（“/*[@id='ext-gen203']]/svg/a[以（@title（），'montana'）]开头]”）；然后我得到一个非接触性的例外。WebElement montana=driver.findElement（By.xpath（“/*[@id='ext-gen203']]/svg/a[以（@title'montana'）]开头]”）；找到它：Selenium没有检测到

g

、

svg

和

path

元素，您必须以不同的方式调用它们：

/*[name（）='tagname']

。请阅读我的文章。我试过了，效果很好。在您的情况下，以下操作可能会起作用：

WebElement montana=driver.findElement（By.xpath（“/*[@id='ext-gen203']/*[name（）='svg']/a[以（@title，'montana'）]开头]）。（网站现在关闭了，我无法查看）我得到了一些答案和建议。下面是一个最简单的XPath查询：
/*[name（）='a'][@*[name（）='title'][.='Alaska']]
。测试和批准。
webDriver.findElement(
  By.xpath(
    '//*[@id="chartdiv"]/div/div[1]/*[name()="svg"]/*[name()="g"][7]/*[name()="g"]/*[name()="g"][1]/*[name()="path"][starts-with(@d, "M371.75,174.28l")]'
  )
).click();
