is_exist

is_exist(); - check for an element in the DOM model (available from version 4.6.41)

After the function returns the result of their work in the script (the return value type is boolean):
  • true – executed successfully
  • false to find this element failed (e.g. no items that meet the specified criteria or not this frame)

    PHP example:

    <?php $xhe_host = "127.0.0.1:7014";
     
    //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> interface->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Let's go to the polygon:";
    echo $browser->navigate("http://wordstat.yandex.ru")."<br>";
     
    //2
    echo "2.Is there a zero-numbered button:";
    echo $button->get_by_number(0)->is_exist()."<br>";
     
    //3
    echo "3.Does test-region:";
    if(!$div->get_by_name("test-region")->is_exist())
    echo "does not exist <br>";
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7010"
    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> interface.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Let's go to the polygon:")
    echo(browser.navigate("http://www.humanemulator.net/poligon/button.html"), "<br>")
     
    # 2
    echo("2.Is there a zero-numbered button:")
    echo(button.get_by_number(0) .is_exist(), "<br>")
     
    # 3
    echo("3.Non-existent button:")
    if not div.get_by_number(100500) .is_exist():
    echo("does not exist <br>")
     
    # end
    echo("<hr> <br>")
     
    # Quit
    app.quit()
