org.openqa.selenium.WebDriverException: ReferenceError: jQuery is not defined

Question

您好，我正在尝试使用 Webdriver 为 firefox 配置文件编写自主测试，我在创建 Driver 对象时启用了等于 true 的 javascript。

在某些视图中，jquery 响应较晚，因此我尝试在 webdriver 代码中进行一次检查以等待 JQuery 处理

waitForJQueryProcessing 的代码 sn-p：

public static boolean waitForJQueryProcessing(WebDriver driver,
        int timeOutInSeconds) {
    boolean jQcondition = false;
    try {
        new WebDriverWait(driver, timeOutInSeconds) {
        }.until(new ExpectedCondition<Boolean>() {

            @Override
            public Boolean apply(WebDriver driverObject) {
                return (Boolean) ((JavascriptExecutor) driverObject)
                        .executeScript("return jQuery.active == 0");
            }
        });
        jQcondition = (Boolean) ((JavascriptExecutor) driver)
                .executeScript("return jQuery.active == 0");
        return jQcondition;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return jQcondition;
}

但是上面的代码是上升异常

我用谷歌搜索在 webdriver 对象中设置 jquery 文件路径，但没有找到任何结果

我希望这是有道理的。

谢谢 高拉夫

改用这个：

public static boolean waitForJQueryProcessing(WebDriver driver,
        int timeOutInSeconds) {
    boolean jQcondition = false;
    try {
        new WebDriverWait(driver, timeOutInSeconds) {
        }.until(new ExpectedCondition<Boolean>() {

            @Override
            public Boolean apply(WebDriver driverObject) {
                return (Boolean) ((JavascriptExecutor) driverObject)
                        .executeScript("return jQuery.active == 0");
            }
        });
        jQcondition = (Boolean) ((JavascriptExecutor) driver)
                .executeScript("return window.jQuery != undefined && jQuery.active === 0");
        return jQcondition;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return jQcondition;
}

你原来的代码sn-p的变化是：

.executeScript("return window.jQuery != undefined && jQuery.active === 0");

这将确保在检查是否有任何活动的 jQuery 进程之前定义了您的 jQuery 对象。 Selenium 运行速度很快，有时可以在 jQuery 有机会加载到您正在测试的页面之前对其进行查询。

有一个更短的代码版本适合我：

public void waitForAjaxLoad(WebDriver driver) throws InterruptedException{
    JavascriptExecutor executor = (JavascriptExecutor)driver;
    if((Boolean) executor.executeScript("return window.jQuery != undefined")){
        while(!(Boolean) executor.executeScript("return jQuery.active == 0")){
            Thread.sleep(1000);
        }
    }
    return;
}

毫秒（1000）可以添加到方法的参数中。
