get_defer_by_src
get_defer_by_src($src,$frame=-1); - get defer from the script with the specified src
Defer allows you to control the script execution status, i.e. if it is equal to true, the script is protected from execution and is not executed, by default, or if it is not set, it is equal to false - the script will be executed when its turn comes.
$src – src by which we find the element we need on the page (string). To find out the src of an element, you can use either the element inspector or 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 testing, the function returns the result of its work to the script :
defer – returns the defer of the found script (boolean)false – this script could not be found (for example, there are no elements that meet the specified criteria or there is no such frame), the return value type is boolean
