url参数转对象
const parseQueryString = function(url) { //url参数转对象
url = !url ? window.location.href : url;
if (url.indexOf('?') === -1) {
return {};
}
let search = url[0] === '?' ? url.substr(1) : url.substring(url.lastIndexOf('?') + 1);
if (search === '') {
return {};
}
search = search.split('&');
let query = {};
for (let i = 0; i < search.length; i++) {
let pair = search[i].split('=');
query[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
}
return query;
}
对象转url参数【对象序列化】
const stringfyQueryString = function(obj) { //对象序列化【对象转url参数】
if (!obj) return '';
let pairs = [];
for (let key in obj) {
let value = obj[key];
if (value instanceof Array) {
for (let i = 0; i < value.length; ++i) {
pairs.push(encodeURIComponent(key + '[' + i + ']') + '=' + encodeURIComponent(value[i]));
}
continue;
}
pairs.push(encodeURIComponent(key) + '=' + encodeURIComponent(obj[key]));
}
return pairs.join('&');
}
