JS: temporarily disable page rendering (possible?)

Question

I'm tryin to sort a big html table using JS. It takes a lot of cpu% to rearrange all the rows of this table. I think the big part of this problem is: every time my script moves a pair of rows, the browser starts refreshing the table

So, I'm searching for any way to temporarily tell the browser something like "wait, I'm sorting this table, dont waste CPU for rendering until I'll finish, plz?"

Basically, I need something lke "Memo1.lines.beginupdate / Memo1.lines.endupdate" in delphi >.<

Answer 1

alert(string) stops rendering, and not asyncronous calls, but not loading. You may prompt "too many cells to load, please wait" you may got the desired behavior. note that, in order to work, string should be a non empty string after trim so a white space is not valid.

You can disable most of the background rendering by disabling displaying of the parent element. Since the parent element is not displayed, client's renderer has nothing to render and also does not recompute sizes. Be aware that when you are updating the content, you will loose focus if it was present wihtin the parent Element.

To achieve something like Memo1.lines.beginupdate and Memo1.lines.endupdate use this:

originalStyleDisplay = myMemo1Div.style.display;
myMemo1Div.style.display = 'none';
try {
  mySorting();
} catch() { }
myMemo1Div.style.display = originalStyleDisplay;

It looks like the python environment which you have installed the pyautogui was not the python environment you have selected in the VSCode.

You can get where you have installed the pyautogui through pip show pyautogui.

You can click the python interpreter version on the bottom-left of the VSCode to switch your python interpreter or reinstall the pyautogui in the selected environment.

After you select the environment in the VSCode, you can open a new terminal in the VSCode through Ctrl+Shift+`. The Python extension will help you activate the environment in the terminal and the package will be installed into the selected python environment.
