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。

2k20更新:使用Josh的URLSearchParams.toString()解决方案。

旧的回答:

没有jQuery

var params = {
    parameter1: 'value_1',
    parameter2: 'value 2',
    parameter3: 'value&3' 
};

var esc = encodeURIComponent;
var query = Object.keys(params)
    .map(k => esc(k) + '=' + esc(params[k]))
    .join('&');

对于不支持需要ES5的箭头函数语法的浏览器，请更改.map…行

    .map(function(k) {return esc(k) + '=' + esc(params[k]);})

URLSearchParams API在所有现代浏览器中都可用。例如:

const params = new URLSearchParams({ var1:“价值”, var2:“value2”, 加勒比海盗:“foo”, })； console.log (params.toString ()); / /打印“var1 = value&var2 = value2&arr = foo”

这些答案是非常有用的，但我想添加另一个答案，这可能会帮助你建立完整的URL。 这可以帮助你连接基本url，路径，哈希和参数。

var url = buildUrl('http://mywebsite.com', {
        path: 'about',
        hash: 'contact',
        queryParams: {
            'var1': 'value',
            'var2': 'value2',
            'arr[]' : 'foo'
        }
    });
    console.log(url);

你可以通过npm https://www.npmjs.com/package/build-url下载

演示:

;(function () { 'use strict'; var root = this; var previousBuildUrl = root.buildUrl; var buildUrl = function (url, options) { var queryString = []; var key; var builtUrl; var caseChange; // 'lowerCase' parameter default = false, if (options && options.lowerCase) { caseChange = !!options.lowerCase; } else { caseChange = false; } if (url === null) { builtUrl = ''; } else if (typeof(url) === 'object') { builtUrl = ''; options = url; } else { builtUrl = url; } if(builtUrl && builtUrl[builtUrl.length - 1] === '/') { builtUrl = builtUrl.slice(0, -1); } if (options) { if (options.path) { var localVar = String(options.path).trim(); if (caseChange) { localVar = localVar.toLowerCase(); } if (localVar.indexOf('/') === 0) { builtUrl += localVar; } else { builtUrl += '/' + localVar; } } if (options.queryParams) { for (key in options.queryParams) { if (options.queryParams.hasOwnProperty(key) && options.queryParams[key] !== void 0) { var encodedParam; if (options.disableCSV && Array.isArray(options.queryParams[key]) && options.queryParams[key].length) { for(var i = 0; i < options.queryParams[key].length; i++) { encodedParam = encodeURIComponent(String(options.queryParams[key][i]).trim()); queryString.push(key + '=' + encodedParam); } } else { if (caseChange) { encodedParam = encodeURIComponent(String(options.queryParams[key]).trim().toLowerCase()); } else { encodedParam = encodeURIComponent(String(options.queryParams[key]).trim()); } queryString.push(key + '=' + encodedParam); } } } builtUrl += '?' + queryString.join('&'); } if (options.hash) { if(caseChange) builtUrl += '#' + String(options.hash).trim().toLowerCase(); else builtUrl += '#' + String(options.hash).trim(); } } return builtUrl; }; buildUrl.noConflict = function () { root.buildUrl = previousBuildUrl; return buildUrl; }; if (typeof(exports) !== 'undefined') { if (typeof(module) !== 'undefined' && module.exports) { exports = module.exports = buildUrl; } exports.buildUrl = buildUrl; } else { root.buildUrl = buildUrl; } }).call(this); var url = buildUrl('http://mywebsite.com', { path: 'about', hash: 'contact', queryParams: { 'var1': 'value', 'var2': 'value2', 'arr[]' : 'foo' } }); console.log(url);

你实际上不需要一个表单来做这个Prototype。使用Object即可。toQueryString功能:

Object.toQueryString({ action: 'ship', order_id: 123, fees: ['f1', 'f2'], 'label': 'a demo' })

// -> 'action=ship&order_id=123&fees=f1&fees=f2&label=a%20demo'

如果您不想使用库，这应该涵盖大多数/所有相同的表单元素类型。

function serialize(form) {
  if (!form || !form.elements) return;

  var serial = [], i, j, first;
  var add = function (name, value) {
    serial.push(encodeURIComponent(name) + '=' + encodeURIComponent(value));
  }

  var elems = form.elements;
  for (i = 0; i < elems.length; i += 1, first = false) {
    if (elems[i].name.length > 0) { /* don't include unnamed elements */
      switch (elems[i].type) {
        case 'select-one': first = true;
        case 'select-multiple':
          for (j = 0; j < elems[i].options.length; j += 1)
            if (elems[i].options[j].selected) {
              add(elems[i].name, elems[i].options[j].value);
              if (first) break; /* stop searching for select-one */
            }
          break;
        case 'checkbox':
        case 'radio': if (!elems[i].checked) break; /* else continue */
        default: add(elems[i].name, elems[i].value); break;
      }
    }
  }

  return serial.join('&');
}
