是否有一个快速和简单的方法来编码JavaScript对象到字符串，我可以通过GET请求传递?
没有jQuery，没有其他框架-只有纯JavaScript:)
当前回答
const buildSortedQuery = (args) => { 返回种(args) .sort () .map(key => { 返回window.encodeURIComponent(关键) + ' = ' + window.encodeURIComponent (args(例子)); }) . join (' & '); }; console.log (buildSortedQuery ({ Foo:“你好”， 栏:“100%” })); / /酒吧= 100% 25 foo =你好% 20

好吧，似乎每个人都把他的俏皮话写在这里，所以我的是:
const encoded = Object.entries(obj).map(([k, v]) => `${k}=${encodeURIComponent(v)}`).join("&");
是这样的:
Serialize =函数(obj) { Var STR = []; For (var p in obj) if (obj.hasOwnProperty(p)) { str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]))); ｝ 返回str.join(“&”); ｝ console.log(序列化({ Foo:“你好”， 栏:“100%” })); / / foo =你好% 20 there&bar 25 = 100%
它还转换递归对象(使用PHP“数组”符号表示查询字符串):
serialize = function(obj, prefix) { var str = [], p; for (p in obj) { if (obj.hasOwnProperty(p)) { var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p]; str.push((v !== null && typeof v === "object") ? serialize(v, k) : encodeURIComponent(k) + "=" + encodeURIComponent(v)); } } return str.join("&"); } console.log(serialize({ foo: "hi there", bar: { blah: 123, quux: [1, 2, 3] } })); // foo=hi%20there&bar%5Bblah%5D=123&bar%5Bquux%5D%5B0%5D=1&bar%5Bquux%5D%5B1%5D=2&bar%5Bquux%5D%5B2%5D=3
好吧，这是一个旧的帖子，但我正面临这个问题，我已经找到了我的个人解决方案。也许可以帮助别人…
function objToQueryString(obj){
var k = Object.keys(obj);
var s = "";
for(var i=0;i<k.length;i++) {
s += k[i] + "=" + encodeURIComponent(obj[k[i]]);
if (i != k.length -1) s += "&";
}
return s;
};
我对JSON stringfier进行了比较，结果如下:
JSON: {"_id":"5973782bdb9a930533b05cb2","isActive":true,"balance":"$1,446.35","age":32,"name":"Logan Keller","email":"logankeller@artiq.com","phone":"+1 (952) 533-2258","friends":[{"id":0,"name":"Colon Salazar"},{"id":1,"name":"French Mcneil"},{"id":2,"name":"Carol Martin"}],"favoriteFruit":"banana"}

其中最短的是URL对象表示法。
使用Node.js v6.6.3
const querystring = require('querystring')
const obj = {
foo: 'bar',
baz: 'tor'
}
let result = querystring.stringify(obj)
// foo=bar&baz=tor
参考:查询字符串
