jQuery在document.ready中未定义

我正在检查我的selenium脚本是否完成ajax调用,我首先检查文档是否准备就绪然后检查是否定义了jQuery然后检查活动状态

public class WaitForAjaxToLoad {
public static void waitForAjaxToLoad(WebDriver driver) {

        final JavascriptExecutor js= (JavascriptExecutor) driver;
        WebDriverWait wait = new WebDriverWait(driver, 15);
        ExpectedCondition<Boolean> e = new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver driver) {

               if(js.executeScript("return document.readyState").equals("complete"))
               {
                    if((boolean) js.executeScript("return window.jQuery != undefined")) {
                      Boolean status= (Boolean) js.executeScript("return jQuery.active==0");
                      System.out.println("Jquery is defined active status:"+status+"for thread:"+Thread.currentThread().getId());
                        if (status) {
                            return true;
                        } else {
                            return false;
                        }
                    }
                    else {
                        System.out.println("jQuery is undefined for thread "+Thread.currentThread().getId());
                        return false;
                    }
               }
               else {
                   System.out.println("Document is not ready for thread "+Thread.currentThread().getId());
                   return false;
               }


            }
        };  
         wait.until(e);

 }
}

当我执行我的脚本时,文档已准备好但jQuery未定义。 当测试方法并行执行时会发生这种情况。 一旦文档准备就绪,为什么我的jQuery未定义?

为Java调整this answer,您的测试可以大大简化 - 在我看来,没有丢失任何有价值的内容:

WebDriverWait wait = new WebDriverWait(driver, 15);
wait.until(new Function<WebDriver, WebElement>() {
    public Boolean apply(WebDriver driver) {
        return js.executeScript("return jQuery.active == 0");
    }
});
