创建一个URL对象并将值附加到seachParameters

let stringUrl = "http://www.google.com/search";
let url = new URL(stringUrl);
let params = url.searchParams;
params.append("q", "This is seach query");

console.log(url.toString());

输出将是

http://www.google.com/search?q=This+is+seach+query

不，我认为标准JavaScript没有内置这个功能，但Prototype JS有这个功能(当然大多数其他JS框架也有，但我不知道它们)，他们称之为序列化。

I can reccomend Prototype JS, it works quite okay. The only drawback I've really noticed it it's size (a few hundred kb) and scope (lots of code for ajax, dom, etc.). Thus if you only want a form serializer it's overkill, and strictly speaking if you only want it's Ajax functionality (wich is mainly what I used it for) it's overkill. Unless you're careful you may find that it does a little too much "magic" (like extending every dom element it touches with Prototype JS functions just to find elements) making it slow on extreme cases.

正如Stein所说，您可以使用http://www.prototypejs.org中的原型javascript库。 包括JS，这很简单，$('formName').serialize()将返回你想要的!

现在回答你的问题可能太迟了。 我有同样的问题，我不喜欢不断追加字符串创建URL。所以，我开始使用$。Param techhouse解释道。 我还找到了一个URI.js库，可以轻松地为您创建url。这里有几个例子可以帮助你: 这是其中之一:

var uri = new URI("?hello=world");
uri.setSearch("hello", "mars"); // returns the URI instance for chaining
// uri == "?hello=mars"

uri.setSearch({ foo: "bar", goodbye : ["world", "mars"] });
// uri == "?hello=mars&foo=bar&goodbye=world&goodbye=mars"

uri.setSearch("goodbye", "sun");
// uri == "?hello=mars&foo=bar&goodbye=sun"

// CAUTION: beware of arrays, the following are not quite the same
// If you're dealing with PHP, you probably want the latter…
uri.setSearch("foo", ["bar", "baz"]);
uri.setSearch("foo[]", ["bar", "baz"]);`

这并没有直接回答您的问题，但这里有一个通用函数，它将创建一个包含查询字符串参数的URL。参数(名称和值)被安全转义以包含在URL中。

function buildUrl(url, parameters){
  var qs = "";
  for(var key in parameters) {
    var value = parameters[key];
    qs += encodeURIComponent(key) + "=" + encodeURIComponent(value) + "&";
  }
  if (qs.length > 0){
    qs = qs.substring(0, qs.length-1); //chop off last "&"
    url = url + "?" + qs;
  }
  return url;
}

// example:
var url = "http://example.com/";

var parameters = {
  name: "George Washington",
  dob: "17320222"
};

console.log(buildUrl(url, parameters));
// => http://www.example.com/?name=George%20Washington&dob=17320222

Querystring可以提供帮助。

所以，你可以

const querystring = require('querystring')

url += '?' + querystring.stringify(parameters)
