Hide URL parameters using Javascript's history.replaceState methods. The server (PHP or whatever) will still see it of course, but this script will quickly 'hide' the parameters. Don't use this to hide anything sensitive - there shouldn't be anything sensitive in GET anyway, but I use this to hide various un-pretty things like ?error=invalidPass…

| function getURLParameter(name) { | |
| return decodeURI((RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]); | |
| } | |
| function hideURLParams() { | |
| //Parameters to hide (ie ?success=value, ?error=value, etc) | |
| var hide = ['success','error']; | |
| for(var h in hide) { | |
| if(getURLParameter(h)) { | |
| history.replaceState(null, document.getElementsByTagName("title")[0].innerHTML, window.location.pathname); | |
| } | |
| } | |
| } | |
| //Run onload, you can do this yourself if you want to do it a different way | |
| window.onload = hideURLParams; |
One downside to this is that the "state" represented by the URL parameters is lost if you reload the page - worth taking notice of
Does anyone have a solution or at least an idea worth exploring that enables us to hold the parameters even after the reload?
ps. Scott thank you so much for the solution! 🙏
@nube-duo I suppose the simplest thing to do is to store the parameters in sessionStorage and just read from there until the search object changes. This uses some newer browser APIs since I originally posted this 9 years ago, but should work:
function persistParams() {
const PARAMS_KEY = "__params";
if (performance.navigation.type === performance.navigation.TYPE_RELOAD) {
const persistedParams = sessionStorage.getItem(PARAMS_KEY);
if (persistedParams) {
return persistedParams;
}
}
sessionStorage.setItem(PARAMS_KEY, location.search);
return location.search;
}
function hideParams() {
persistParams();
history.replaceState(null, document.title, window.location.pathname);
window.addEventListener("beforeunload", () => {
history.replaceState(
null,
document.title,
window.location.pathname + (sessionStorage.getItem(PARAMS_KEY) || "")
);
});
}
window.addEventListener("load", hideParams, false);
Tnx for this!!
is there any way to adapt the script to hide the params when hovering a url somewhere on a page?

i made this, seems to do the trick:
<?php // testfilename: hidehoverparams.php
session_start();
?>
<!-- My piece -->
<script>
if (sessionStorage.params)
{
let urlparams = sessionStorage.getItem("params");
//clear the params
sessionStorage.removeItem("params");
// rename hidehoverparams.php to the file you want to call, this puts the params back in $_GET
window.location.href = 'https://<?php echo $_SERVER['SERVER_NAME'];?>/hidehoverparams.php?'+urlparams;
}
</script>

I don't normally comment on these (I know, I should) - but I just had to say thank you. This works brilliantly! Bravo!
