get_rows_by_number

get_rows_by_number($number,$frame=-1); - get the number of lines in the text with the specified number

$number – the number by which we find the element we need on the page (int) . Element numbers start with 0 and different types of elements have their own numbering.To find out the item number, you can use either the item inspector or the context menu, or view it in the list of items.

$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 :

number of lines – the number of lines in the found text (int)

-1 – it was not possible to find such an element (for example, there are no elements that meet the specified criteria or there is no such frame), the return value type is 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> textarea->".basename(__FILE__)."</font> <hr>";
 
//1
echo "1.Let's go to the polygon:";
echo $browser->navigate("http://humanemulator.net/poligon/textarea.html")."<br>";
 
//2
echo "2.Get the number of lines for the element with number 3:";
echo $textarea->get_rows_by_number(3)."<br>";
 
//3
echo "3.Get the number of lines for a nonexistent element:";
if($textarea->get_rows_by_number(100500) == - 1)
      echo "no such element <br>";
 
//4
echo "4.Get the number of lines for the element with number 0 in the zero frame:";
echo $textarea->get_rows_by_number(0,0)."<br>";
 
//five
echo "5.Get the number of lines for a nonexistent element in a zero frame:";
if($textarea->get_rows_by_number(100500,0) == - 1)
      echo "no such element <br>";
 
//6
echo "6.Get the number of lines for an element in a nonexistent frame:";
if($textarea->get_rows_by_number(0.5) == - 1)
      echo "no such frame <br>";
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
?>
