Hi ,
We need to restrict the user to click browser back button when working on the WO(Processflow/screenflow). I have placed below script in the harness rule,but no luck.Please advice.
Pega Version: 8.2.1
window.history.forward();
function noBack()
{
window.history.forward();
}

Hello,

I haven't played with this code in many years, so it may need some tweaking and/or adjustments based on the use case and release.
But one of the key differences here is to not blindly disable backspace. Because that will prevent users from correcting input fields. So you will want to add intelligence as to where/when it will apply. Please find a PoC below.
<script>
document.onkeydown = function(event) {
/* IE will sometimes pass a null event */ if (!event) { event = window.event; } var keyCode = event.keyCode;
/* Disable browser back via backspace. textarea and input fields (including passwords) are excluded to allow character deletion */ if (keyCode == 8 && ((event.target || event.srcElement).tagName != "TEXTAREA") && ((event.target || event.srcElement).tagName != "INPUT")) {
/* For IE browsers before IE11 */ if (navigator.userAgent.toLowerCase().indexOf("msie") != -1) { event.returnValue = false; }

/* For modern browsers */ else { event.stopPropagation(); }
return false; } }
