set_redraw

set_redraw($enable=true); - disable or allow redrawing of the current browser. When redrawing is prohibited, everything that happens in the browser is processed, but not displayed. on heavily loaded pages, this can significantly speed up the script execution speed. Set separately for each browser page.

the input Function accepts parameters:

  • $enable – specifies to disable (false) or allow (true) browser redrawing

    After testing, the function returns the result of its work to the script :
  • true – completed successfully
  • false – failed

    PHP example:

    <?php $xhe_host = "127.0.0.1:7020";
     
    //connect the object to control the emulator, if not already connected
    if(!isset($path))
      $path = "../../../Templates/xweb_human_emulator.php";
    require($path);
     
    //Start
    echo "<hr> <font color = blue> browser->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Go to a blank page:";
    echo $browser->navigate("about: blank")."<br>";
     
    //2
    echo "2.Disable redrawing to speed up work:";
    echo $browser->set_redraw(false)."<br>";
     
    //3
    echo "3.Go to Yandex and get the href of the link with number 0:";
    $browser->navigate("http://www.ya.ru");
    echo $anchor->get_href_by_number(0)."<br>";
    sleep(5);
     
    //4
    echo "4.Go to MSN:";
    echo $browser->navigate("http://www.msn.com")."<br>";
     
    //five
    echo "5.Allow redrawing:";
    echo $browser->set_redraw(true)."<br>";
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7013"

    # Start
    echo("<hr> <font color = blue> browser.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Go to blank page:")
    echo(browser.navigate("about: blank"), "<br>")
     
    # 2
    echo("2.Disable redrawing to speed up work:")
    echo(browser.set_redraw(false), "<br>")
     
    # 3
    echo("3.Go to Yandex and get the href of the link with the number 0:")
    browser.navigate("http://www.ya.ru")
    echo(anchor.get_href_by_number(0), "<br>")
