在具有随机数的字符串上使用替换

Question

我正在尝试在以下URL字符串中替换“最低”和“最高”价格的值：

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+/,'');

努力取代价格。

Answer 1

用min替换max和''值

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);

Answer 2

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

Answer 3

regex

使用match和toStringDictionary查找数字。
