get_selected_index_by_name

get_selected_index_by_name($name,$frame=-1); - this function is used to get the index of the selected option from the ListBox on the current page, finding it by the specified name.

the input Function accepts parameters:

  • $name – the name by which we find the element we need on the page (string). To find out the name of an element, you can use either the element inspector, the context menu, or view it in the list of elements.
  • $frame – the number of the frame in which we are looking for the element (string). Frame numbers start from zero. By default, -1 - the element is not in the frame. You can find out the number of the frame that contains the item you need from the task inspector, the context menu, and the item list panel.
    With version 4.6.41 of postpone: you can pass nested frames, the principle is the same, a string is numbered frames separated by : for example, if you transfer "1:0:5" - will the selected frame number 1 in it under the frame with the number 0 and the subframe number 5
    Since version 7.0.38, you can pass "url=>XXX", then search for the frame that contains the specified src, or pass "name=>XXX" - then the frame will be searched by the specified part of the name.

    After testing, the function returns the result of its work to the script :
  • index of the selected option – returns the index of the selected option in the ListBox, numbering options starts from zero. If there is no selected option, it returns -1 (int)

    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> listbox->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Let's go to the polygon:";
    echo $browser->navigate("http://humanemulator.net/poligon/listbox.html")."<br>";
     
    //2
    echo "2.Get the selected index of the element named hero []:";
    echo $listbox->get_selected_index_by_name("hero []")."<br>";
     
    //3
    echo "3.Get the selected index of a nonexistent element:";
    if($listbox->get_selected_index_by_name("ptych") == - 1)
    echo "no such element <br>";
     
    //4
    echo "4.Get the selected index of the element named hero [] in frame zero:";
    echo $listbox->get_selected_index_by_name("hero []", 0)."<br>";
     
    //five
    echo "5.Get the selected index of the nonexistent element in the zero frame:";
    if($listbox->get_selected_index_by_name("ptych", 0) == - 1)
    echo "no such element <br>";
     
    //6
    echo "6.Get the selected item index in a nonexistent frame:";
    if($listbox->get_selected_index_by_name("hero []", 100500) == - 1)
    echo "no such frame <br>";
