select_random_by_attribute

select_random_by_attribute($attr_name,$attr_value,$exactly,$frame=-1); - this function is used to select a random option in the ListBox on the current page, finding it by the specified attribute value (available since version 7.0.27).

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 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> 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.Select randomly in the element with name = contries:";
echo $listbox->select_random_by_attribute("name", "contries", true)."<br>";
 
//3
echo "3.Select randomly in a nonexistent element:";
if(!$listbox->select_random_by_attribute("name", "ptych", true))
   echo "no such element <br>";
 
//4
echo "4.Select randomly in an element named contries in frame zero:";
echo $listbox->select_random_by_attribute("name", "contries", true, 0)."<br>";
 
//five
echo "5.Let's randomly select a nonexistent element in the zero frame:";
if(!$listbox->select_random_by_attribute("name", "ptych", false, 0))
   echo "no such element <br>";
 
//6
echo "6.Select randomly in an element in a non-existent frame:";
if(!$listbox->select_random_by_attribute("name", "contries", true, 100500))
   echo "no such frame <br>";
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
