如何在Java中使用Selenium從Tooltip獲取文本？

Question

我正在嘗試使用Java獲取工具提示的文本

奇怪的是，我得到了范圍的任何屬性，甚至是TagName() ，但是當使用getText()時卻得到了一個空String

HTML代碼：

<div id="currentRebalancing1">
    <div class="chart" id="donutCR1" data-highcharts-chart="8">
        <div id="highcharts-cva4evt-30"
             style="position: relative; overflow: hidden; width: 400px; height: 570px; text-align: left; line-height: normal; z-index: 0; left: 0.0999756px; top: 0.683334px;"
             class="highcharts-container ">
            <svg version="1.1" class="highcharts-root " width="400" height="570" viewBox="0 0 400 570">
                <g class="highcharts-series-group">

            <div class="highcharts-label highcharts-tooltip"
                 style="position: absolute; left: 160px; top: -9999px; opacity: 0; pointer-events: none; visibility: visible;">
                <span style="font-family: &quot;Lucida Grande&quot;, &quot;Lucida Sans Unicode&quot;, Arial, Helvetica, sans-serif; font-size: 12px; position: absolute; white-space: nowrap; color: rgb(51, 51, 51); margin-left: 0px; margin-top: 0px; left: 8px; top: 8px;">
                Carmignac Sécurité A EUR Acc  
                    <b>73.00%</b>
                </span>
            </div>
        </div>
    </div>
</div>

Java代碼：

s_Path = "//*[@id='currentRebalancing1']//*[contains(@class,'highcharts-point highcharts-color-0')]";

Actions builder = new Actions(driver);
WebElement w_AssetWeight = driver.findElement(By.xpath(s_Path));
                builder.moveToElement(w_AssetWeight).build().perform();
Thread.sleep(2000);

s_Path = "//*[@id='currentRebalancing1']//div[contains(@class, 'highcharts-label')]//*[contains(. , 'Carmignac')]";

String s_Result = driver.findElement(By.xpath(s_Path)).getAttribute("style");
// Here s_Result has the value of 'Style'
s_Result = driver.findElement(By.xpath(s_Path)).getTagName();
// Here s_Result = "span"
s_Result = driver.findElement(By.xpath(s_Path)).getText();
//Here s_Result = "" instead of "Carmignac Sécurité A EUR Acc 73.00%"

s_Result的第一個值符合預期。

s_Result的第二個值是“ span”（符合預期）。

s_Result的第三個值是“”（預期為“ CarmignacSécuritéA EUR Acc。73.00％”）

期望的元素是動態元素，因此要提取工具提示，您需要為WebViewrElementLocated visibilityOfElementLocated()引入WebDriverWait ，並且可以使用以下任何一種Locator Strategies ：

• cssSelector ：

   System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div#currentRebalancing1 div.highcharts-label.highcharts-tooltip"))).getText()); 

• xpath ：

   System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@id='currentRebalancing1']//div[@class='highcharts-label highcharts-tooltip']"))).getText());
