I want auto click left button by Autofill.

Type = JavaScript  Value = document.querySelector('input[type="submit"]').click();

But it doesn't work,

debug console show below message:

[Autofill] The following JavaScript code was not executed:

document.querySelector('input[type="submit"]').click()

Error: Cannot read property 'click' of null

Frame: https://www.hpb.gov.tw/p/412-1000-116.php?Lang=zh-tw

That's because when it goes to the next page there are two inputs there that match input[type="submit"]. Try changing your JS code to this:

document.querySelector('input[name="ctl00$ContentPlaceHolder1$btnOK"]').click();

i also kind of had the same problem, my code was:

$(document).ready(function clickbutton(){

    'use strict';

setInterval(function($){ document.getElementById('nextactivity').click(); },15000);

})(jQuery);

and it said: caught TypeError: Cannot read property 'click' of null.

hope you can help!

thanks
