                            var h=canvas.height;
                              ctx.fillStyle = "#FFF";
                                ctx.fillRect(0, 0, w, h);
                              var cap =document.querySelector("body > div.container-fluid > div > div > div:nth-child(3) > div > div > form > div:nth-child(2) > div > div > img")

                            document.head.appendChild(imported);

using it on this website to get the captcha image as dataUrl

Another Question: is this code contain jquery ?

On your both examples you have an error `Uncaught TypeError: $(...).datepicker is not a function` — Serghei Leonenco, Aug 16 '19 at 02:30

the code working in a website but not in this website i posted in the question i think something about using jquery twice — user11845248, Aug 16 '19 at 02:58
This problem occur usually at the time when you load your library early or without needed component. — Serghei Leonenco, Aug 16 '19 at 03:00
@SergheiLeonenco what library ? i'm not the owner of the website btw — user11845248, Aug 16 '19 at 03:01
i mean the order how you load the jquery and bootstrap libraries. that is the issue. — Serghei Leonenco, Aug 16 '19 at 03:03
@SergheiLeonenco in android code, i use a webview so i run the js code after the website fully loaded using `onPageFinished ` so everything loaded correctly — user11845248, Aug 16 '19 at 03:35
