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.

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"]);`

如果你正在使用jQuery，你可能想要查看jQuery.param() http://api.jquery.com/jQuery.param/

例子:

var params = {
    parameter1: 'value1',
    parameter2: 'value2',
    parameter3: 'value3' 
};
var query = $.param(params);
console.log(query);

这将打印出:

parameter1=value1&parameter2=value2&parameter3=value3

Querystring可以提供帮助。

所以，你可以

const querystring = require('querystring')

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

我自己也不完全确定，我记得jQuery在一定程度上做到了这一点，但它根本不能处理分层记录，更不用说以php友好的方式了。

有一件事我很确定，当构建url并将产品粘贴到dom中时，不要仅仅使用字符串胶水来做，否则您将打开自己的方便之门。

For instance, certain advertising software in-lines the version string from whatever runs your flash. This is fine when its adobes generic simple string, but however, that's very naive, and blows up in an embarrasing mess for people whom have installed Gnash, as gnash'es version string happens to contain a full blown GPL copyright licences, complete with URLs and <a href> tags. Using this in your string-glue advertiser generator, results in the page blowing open and having imbalanced HTML turning up in the dom.

这个故事的寓意是:

   var foo = document.createElement("elementnamehere"); 
   foo.attribute = allUserSpecifiedDataConsideredDangerousHere; 
   somenode.appendChild(foo); 

不是:

   document.write("<elementnamehere attribute=\"" 
        + ilovebrokenwebsites 
        + "\">" 
        + stringdata 
        + "</elementnamehere>");

谷歌需要学习这个技巧。我试图报告这个问题，但他们似乎并不在意。

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
