<p>{{domxref("Location")}} 接口的 <strong><code>search</code></strong> 属性会返回一段 {{domxref("USVString")}}，其中包含一个URL标识中的 <code>'?'</code> 以及跟随其后的一串URL查询参数。</p>

<p>现代浏览器提供 <code><a href="/en-US/docs/Web/API/URLSearchParams/get#Examples">URLSearchParams</a></code> 和 <code><a href="/en-US/docs/Web/API/URL/searchParams#Examples">URL.searchParams</a></code> 两个接口，使得从查询字符串中解析出查询参数变得更加容易。</p>
