利用正则表达式实现将查询字符串转成 Javscript 对象

querystring-to-obj.js

const URL = "http://helloworld.com?user=Jack&pwd=123456&hobby=read";
const RE = /(\?|\&)([^=]+)\=([^&]+)/g;
let paramsObject = {};

URL.replace(RE, (match, p1, p2, p3) => {
    paramsObject[p2] = p3;
});

console.log(paramsObject);
// will be { user: 'Jack', pwd: '123456', hobby: 'read' }

//*************************************************************
// ES5 方法封装 getUrlArgs 返回格式 {has:[true|false], data:{}}
//*************************************************************
getUrlArgs = function() {
    var URL = window.location.href;
    var RE = /(\?|\&)([^=]+)\=([^&]+)/g;
    var result = {
        has: false,
        data: {}
    };
    URL.replace(RE, function(match, p1, p2, p3) {
        result.data[p2] = p3;
    });
    for (var prop in result.data) {
        result.has = true;
        break;
    }
    return result;
}
