get_by_js

get_by_js($js,$add_file="",$frame=-1); - get the element interface using JS for search. the code must implement the JS_XHE_GetElement function, which searches for an element using JS based on the specified criteria (Available since version 4.10.2)

The function accepts parameters as input:br>

$js – code function Java Script: JS_XHE_GetElement that gets the desired item.

$add_file – the file from which to load additional JS code.

$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 :

DOM element interface – an object that allows you to quickly perform any operations with the found element, the return value type XHEInterface

PHP example:

<?php $xhe_host = "127.0.0.1:7013";
 
//connect the object to control the emulator, if not already connected
if(!isset($path))
   $path = "../../../Templates/xweb_human_emulator.php";
require($path);
$path = "../../../Templates/simple_html_dom.php";
require($path);
 
//Start
echo "<hr> <font color = blue> anchor->".basename(__FILE__)."</font> <hr>";
 
//1
echo "1.Let's go to the polygon:";
$browser->set_wait_params(10,1);
echo $browser->navigate("http://bigfozzy.com")."<br>";
 
//2
echo "2.Get an element by JS function(the function name must be JS_XHE_GetElement):";
$obj = $element->get_by_js("function JS_XHE_GetElement() {var elm = document.querySelector('.menu_lnk'); return elm;}");
echo $obj->get_x()."".$obj->get_y();
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
?>
