How to click a browser button with JavaScript automatically?
setInterval(function () {document.getElementById("myButtonId").click();}, 1000);
This will give you some control over the clicking, and looks tidy
<script>var timeOut = 0;function onClick(but){ //code clearTimeout(timeOut); timeOut = setTimeout(function (){onClick(but)},1000);}</script><button onclick="onClick(this)">Start clicking</button>
