Question

这是我在Web驱动程序的每个页面上执行java脚本的代码，并根据我的脚本从cookie中获取值。它工作正常。但问题是，如果页面刷新它无法正常工作，因为我使用当前URL检查以前的URL。如何处理页面的刷新。帮助我

         String s="Some javascript";
         String prev = driver.getTitle();

        ((JavascriptExecutor) driver).executeScript(s);
        iflag = 0;
        Boolean record = Boolean.valueOf(true);

        while (record.booleanValue()) {
            try {

                curr = driver.getTitle();
      //Check if page changed or not
               ///help needed here
                if (!(prev.equals(curr))) {
                    System.out.println("changes");
                    ((JavascriptExecutor) driver).executeScript(s);
                    prev = curr;
                }
                Set<String> wnd_hndls = driver.getWindowHandles();
                Iterator wnd_itr = wnd_hndls.iterator();

                if (!driver.getCurrentUrl().equalsIgnoreCase("about:blank")) {
                    int win_ind = 0;
                    while (wnd_itr.hasNext()) {
                        String wnd_hndlr = (String) wnd_itr.next();
                        win_ind++;
                        Cookie ck_pg = driver.manage().getCookieNamed(wnd_hndlr);
                        if ((ck_pg != null) && (ck_pg.getValue().equalsIgnoreCase("0"))) 
                        {
                            iflag = 1;
                        }
                        if (ck_pg == null) 
                        {
                            iflag = 1;
                        }
                        if (iflag == 1) {

                           //My operation based on executed javascript

                        }
                    }
                }
            } catch (WebDriverException localWebDriverException) {
                driver.quit();
                record = Boolean.valueOf(false);

          }
        }

根据各种因素更改页面可能需要一些时间。您应该等待睡眠新页面上的元素，直到它发生变化。请尝试以下方法：

//To check if page changed or not use this instead of simple driver.getTitle()
int i = 0;
do{
    Thread.sleep(500);// Or wait for element on new page.
    curr = driver.getTitle();
    i++;
}while(prev.equals(curr)&&i<10);
if (!(prev.equals(curr))) {
    System.out.println("changes");
    ((JavascriptExecutor) driver).executeScript(s);
    prev = curr;
}

要刷新页面使用，请执行以下操作：

driver.navigate().refresh();
