is_exist_by_name

is_exist_by_name($name,$frame=-1); - this function is used to check the presence of an element on the page by 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 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 $xhe_host = "127.0.0.1:7013";
 
//connect the object to control the emulator, if not already connected
