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”

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('&');
}

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

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

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”
