How to auto click an input button [duplicate]

Answer 1

I think clicking without being user triggered is not so good practice, you can achieve the same without needing to triggers click, but you can try this

window.onload = function(){
    var button = document.getElementById('clickButton');
    setInterval(function(){
        button.click();
    },1000);  // this will make it click again every 1000 miliseconds
};
