Replacing min and max values with ''

var url_full = "http://foo.com/?q=&min=0&max=789&hellomin=350"

var url_clean = url_full.replace(/&min=\d+/,'&min=').replace(/&max=\d+/,'&max=')
   
console.log(url_clean);

What if they have another parameter in that string called hellomin? Might be useful to keep searching for the &.

> var url = new URL(window.location.href);
> url.searchParams.set('min','100'); window.location.href = url.href;

var url_full = "http://foo.com/?q=&min=0&max=789"

var url_clean = url_full.replace('&min='+ /\d+/,'');
var url_clean = url_full.replace('&max='+ /\d+/,'');
console.log(url_clean);

var regex = /\d+/g;
var string = "http://foo.com/?q=&min=0&max=789";
var matches = string.match(regex);  // creates array from matches
for(var s=0;s<matches.length;s++){
console.log(matches[s]);
}
document.write(matches);

Use regex and match for finding digits.
