如何通过 Java 使用 Selenium 点击元素

Question

我正在尝试使用相邻兄弟从下拉列表中选择值，但不起作用

这里是 HTML：

<div id="dependsOnQuestionDiv"><div class="x-form-field-wrap x-form-field-trigger-wrap" id="ext-gen197" style="width: 17px;"><input type="text" size="24" autocomplete="off" id="dependsOnQuestion" name="dependsOnQuestion" class="x-form-text x-form-field x-trigger-noedit" readonly="" title="" style="width: 345px;"><img src="/mco/extjs/resources/images/default/s.gif" alt="" class="x-form-trigger x-form-arrow-trigger" id="ext-gen198"></div></div>

我已经尝试了这些方法：

(xpath =
 "//input[@id='dependsOnQuestion']/following-sibling::img[@id='ext-gen198']"

和

> css = #dependsOnQuestion ~img "

但是它点击了其他有图片标签的元素

这是另一个图像标签 HTML，当我尝试单击下拉菜单时会单击它

<td class="x-grid3-col x-grid3-cell x-grid3-td-edit  x-action-col-cell" style="width: 41px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-edit x-unselectable" unselectable="on"><img alt="" src="/mco/images/edit-button.png" class="x-action-col-icon x-action-col-0  "></div></td>

<div class="x-grid3-cell-inner x-grid3-col-edit x-unselectable" unselectable="on" xpath="1"><img alt="" src="/mco/images/edit-button.png" class="x-action-col-icon x-action-col-0 " style=""></div>

谁能帮帮我？

Answer 1

到click() 元素上你必须为elementToBeClickable() 诱导WebDriverWait 并且你可以使用以下Locator Strategies 之一：

• cssSelector:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("div#dependsOnQuestionDiv input.x-form-text.x-form-field.x-trigger-noedit#dependsOnQuestion[name='dependsOnQuestion']"))).click();
  

• xpath:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//div[@id='dependsOnQuestionDiv']//input[@class='x-form-text x-form-field x-trigger-noedit' and @id='dependsOnQuestion'][@name='dependsOnQuestion']"))).click();
  

Answer 2

试试下面的XPATH 选项。

xpath = "//img[@id='ext-gen198']/preceding-sibling::input[@id='dependsOnQuestion']"

或

 xpath = "//img[@id='ext-gen198']/preceding-sibling::input[1]"
