如何在 selenium webdriver 中处理 ExtJS 的组合框 [英] how to handle combo boxes of ExtJS in selenium webdriver

问题描述

我有一个基于 ExtJS 的 UI.我已经知道在 ExtJS 中，组合框不是真正的组合框，而是输入文本字段、下拉框图像和列表的组合.现在我能够识别控件，但我坚持从列表中选择值.在 HTML 源代码中，我看到列表显示为一个单独的 div，并在我们单击下拉列表时附加在源代码的末尾.在下拉控件的 HTML 源代码下方找到.{

Hi i have a ExtJS based UI. I have come to know that in ExtJS the combo box is not a real combo box but a combination of input text field, image of drop down box and a list. Now i am able to identify the control but i am stuck at selecting the value from the list. In the HTML source i see that the list is appearing as a seperate div and gets attached at the end of the source when we click on the drop down. find below the HTML source of the drop down control. {

<div id="ext-gen678" class="x-form-field-wrap x-form-btn-plugin-wrap" style="width: 556px;">
<div id="ext-gen676" class="x-form-field-wrap x-form-field-trigger-wrap x-trigger-wrap-focus" style="width: 521px;">
<input id="ext-gen677" type="hidden" name="GHVOg:#concat#~inputFld~ISGP_UNIV:ft_t_isgp.prnt_iss_grp_oid:0" value="">
<input id="GHVOg:Mixh8:0" class="x-form-text x-form-field gs_dropDown_input gs_req x-form-invalid x-form-focus" type="text" autocomplete="off" size="24" style="width: 504px;">
<img id="trigger-GHVOg:Mixh8:0" class="x-form-trigger x-form-arrow-trigger" alt="" src="../../ext/resources/images/default/s.gif">

}

在下拉列表的 HTML 源代码下方找到:

find below the HTML source of the drop down list:

<div id="ext-gen726" class="x-layer x-combo-list x-resizable-pinned" style="position: absolute; z-index: 12007; visibility: visible; left: 294px; top: 370px; width: 554px; height: 123px; font-size: 11px;">
<div id="ext-gen727" class="x-combo-list-inner" style="width: 554px; margin-bottom: 8px; height: 114px;">
<div class="x-combo-list-item"></div>
<div class="x-combo-list-item">12h Universe</div>
<div class="x-combo-list-item">1h Universe</div>
<div class="x-combo-list-item">24h Universe</div>
<div class="x-combo-list-item">2h Universe</div>
<div class="x-combo-list-item x-combo-selected">4h Universe</div>

现在我在从列表中选择值时遇到问题，因为列表的 div 元素没有附加到控件上.另请参阅屏幕截图，其中我有多个类似的控件 [命名为向 Universe 添加安全性"]

Now i have problem selecting the value from the list as the div element of the list is not attached to the control. Also please refer the screen shot, where i have multiple similar controls [Named "Add Security to Universe"]

在屏幕截图中，您可以看到多个下拉菜单 [Add security to Universe] 突出显示，并且所有下拉菜单都有相同的值出现在列表中.那么我如何从下拉列表中识别这些值.我想知道 ExtJS 如何维护下拉 div 元素与组合框小部件的映射，以便我可以使用相同的逻辑来识别列表.谁能告诉我如何在 selenium webdriver 中做这件事?

In the screen shot you can see multiple drop downs [Add security to Universe] highlighted and all the drop downs have same value appearing in the list. so how can i identify these values from the drop down list. I was wondering how ExtJS maintains mapping of the drop down div elements with the combo Box widget so that i could use the same logic for identifying the list. Can anyone tell me how can i go about doing this thing in selenium webdriver?

推荐答案

您是否注意到页面上只有一个可见的 x-combo-list ?(如果你能同时打开两个组合列表，请告诉我)

Did you notice that there will be only one visible x-combo-list on the page? (Let me know if you can open up two combo lists at the same time)

因此你只需要关心可见的x-combo-list.

Therefore you only need to care about the visible one x-combo-list.

Css 选择器:.x-combo-list[style*='visibility: visible;'] .x-combo-list-item

Xpath: //*[contains(@class, 'x-combo-list') and contains(@style, 'visibility: visible;')]///*[contains(@class, 'x-combo-list-item')]

// untested java code, just for the logic
public void clickComboItem(WebElement input, String target) {
    input.click(); // click input to pop up the combo list
    List<WebElement> comboItems = driver.findElements(By.cssSelector(".x-combo-list[style*='visibility: visible;'] .x-combo-list-item"));
    for (int i = 0; i <= comboItems.size(); i++) {
        WebElement item = comboItems.get(i);
        if (item.getText().eqauls(target)) {
            item.click();
            break;
        }
    }
}

// compilable C# version
public void ClickComboItem(IWebElement input, string target) {
    input.Click();
    IList<IWebElement> comboItems = driver.findElements(By.CssSelector(".x-combo-list[style*='visibility: visible;'] .x-combo-list-item"));
    comboItems.First(item => item.Text.Trim() == target).Click();
}
