get_selected_index_by_attribute

get_selected_index_by_attribute($attr_name,$attr_value,$exactly=true,$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 attribute value.

Available from version 4.6.5

The function accepts parameters as input:

  • $attr_name – name of the attribute whose value we will search for the element on the page (string). To find out the attribute names of an element, you can use either the element inspector, the context menu, or view it in the list of elements.
  • $attr_value – the value of the attribute that we will use to search for the element on the page (string). To find out the value of a given attribute for an element, you can use either the element inspector, the context menu, or view it in the list of elements.
  • $exactly – exact match of the value of the specified attribute when searching for an element (boolean), by default 1 - the value of the specified element attribute must completely match the passed parameter ($attr_value). if this parameter is set as 0, the first element is found where the specified attribute value contains the specified string ($attr_value).Starting from version 7.0.25, you can fart the value 2, then attr_value will be interpreted as a regular expression for the Java Script function String.search.
  • $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_attribute("name", "hero []", true)."<br>";
     
    //3
    echo "3.Get the selected index of a nonexistent element:";
    if($listbox->get_selected_index_by_attribute("name", "ptych", true) == - 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_attribute("name", "hero []", true, 0)."<br>";
     
    //five
    echo "5.Get the selected index of the nonexistent element in the zero frame:";
    if($listbox->get_selected_index_by_attribute("name", "ptych", true, 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_attribute("name", "hero []", true, 100500) == - 1)
    echo "no such frame <br>";
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
