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
这是对已接受的解的补充。这适用于对象和对象数组:
parseJsonAsQueryString = function (obj, prefix, objName) {
var str = [];
for (var p in obj) {
if (obj.hasOwnProperty(p)) {
var v = obj[p];
if (typeof v == "object") {
var k = (objName ? objName + '.' : '') + (prefix ? prefix + "[" + p + "]" : p);
str.push(parseJsonAsQueryString(v, k));
} else {
var k = (objName ? objName + '.' : '') + (prefix ? prefix + '.' + p : p);
str.push(encodeURIComponent(k) + "=" + encodeURIComponent(v));
//str.push(k + "=" + v);
}
}
}
return str.join("&");
}
我还添加了objName，如果你使用对象参数，像在ASP。NET MVC动作方法。
其他回答
const serialize = obj => Object.keys(obj).reduce((a, b) =>
a.push(encodeURIComponent(b) + "=" + encodeURIComponent(obj[b])) && a,
[]).join("&");
电话:
console.log(serialize({a:1,b:2}));
// output: 'a=1&b=2
'
您也可以通过使用简单的JavaScript来实现这一点。
const stringData = '？name=Nikhil&surname=Mahirrao&age=30'; const newData= {}; stringData.replace（'？'， ''）.split（'&'）.map（（value） => { const temp = value.split（'='）; 新数据[温度[0]] = 温度[1]; }); console.log（'stringData： '+stringData）; console.log（'newData： '）; console.log（newData）;
对于TS
const convertQueryToString = (data: { [x: string]: any }): string => { const serialize = (obj: { [x: string]: any }, prefix?: string): string => { const str = []; let p; for (p in obj) { if (obj.hasOwnProperty(p)) { const k = prefix ? `${prefix}[${p}]` : p; const v = obj[p]; str.push( v !== null && typeof v === 'object' ? serialize(v, k) : `${encodeURIComponent(k)}=${encodeURIComponent(v)}` ); } } return str.join('&'); }; return serialize(data); };
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。
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
