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:)

这个函数跳过null/undefined值
export function urlEncodeQueryParams(data) {
const params = Object.keys(data).map(key => data[key] ? `${encodeURIComponent(key)}=${encodeURIComponent(data[key])}` : '');
return params.filter(value => !!value).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
如果你想将整个对象作为一个参数传递,例如,?filter={param1: "val1", param2: "val2"}:
const serializeObject = (obj) => {
let objStr = JSON.stringify(obj);
objStr = objStr.replace(/\{/g, encodeURIComponent("{"));
objStr = objStr.replace(/}/g, encodeURIComponent("}"));
objStr = objStr.replace(/:/g, encodeURIComponent(":"));
return objStr;
};
let res = serializeObject({param1: "val1", param2: "val2"});
console.log("serializeObject:", res); //%7B"param1"%3A"val1","param2"%3A"val2"%7D
console.log("serializeObject-decoded:", decodeURIComponent(res)); //{"param1":"val1","param2":"val2"}
如果有很多嵌套对象,前面的答案就不起作用了。
相反,你可以从jquery-param/jquery-param.js中选择函数参数。这对我来说非常有效!
var param = function (a) {
var s = [], rbracket = /\[\]$/,
isArray = function (obj) {
return Object.prototype.toString.call(obj) === '[object Array]';
}, add = function (k, v) {
v = typeof v === 'function' ? v() : v === null ? '' : v === undefined ? '' : v;
s[s.length] = encodeURIComponent(k) + '=' + encodeURIComponent(v);
}, buildParams = function (prefix, obj) {
var i, len, key;
if (prefix) {
if (isArray(obj)) {
for (i = 0, len = obj.length; i < len; i++) {
if (rbracket.test(prefix)) {
add(prefix, obj[i]);
} else {
buildParams(prefix + '[' + (typeof obj[i] === 'object' ? i : '') + ']', obj[i]);
}
}
} else if (obj && String(obj) === '[object Object]') {
for (key in obj) {
buildParams(prefix + '[' + key + ']', obj[key]);
}
} else {
add(prefix, obj);
}
} else if (isArray(obj)) {
for (i = 0, len = obj.length; i < len; i++) {
add(obj[i].name, obj[i].value);
}
} else {
for (key in obj) {
buildParams(key, obj[key]);
}
}
return s;
};
return buildParams('', a).join('&').replace(/%20/g, '+');
};
看起来好一点
objectToQueryString(obj, prefix) {
return Object.keys(obj).map(objKey => {
if (obj.hasOwnProperty(objKey)) {
const key = prefix ? `${prefix}[${objKey}]` : objKey;
const value = obj[objKey];
return typeof value === "object" ?
this.objectToQueryString(value, key) :
`${encodeURIComponent(key)}=${encodeURIComponent(value)}`;
}
return null;
}).join("&");
}
let data = {
id:1,
name:'Newuser'
};
const getqueryParam = data => {
let datasize = Object.keys(data).length;
let initial = '?';
Object.keys(data).map(function (key, index) {
initial = initial.concat(`${key}=${data[key]}`);
index != datasize - 1 && (initial = initial.concat('&'));
});
console.log(initial, 'MyqueryString');
return initial;
};
console.log(getqueryParam(data))//You can get the query string here
If you have baseUrl means to get full query use
baseUrl concat (getqueryParam(数据)。
