最简单的方法之一是使用URLSearchParam接口。

下面是工作代码片段:

let paramObj={},
    querystring=window.location.search,
    searchParams = new URLSearchParams(querystring);    

  //*** :loop to add key and values to the param object.
 searchParams.forEach(function(value, key) {
      paramObj[key] = value;
   });

一个简明的解决方案:

location.search
  .slice(1)
  .split('&')
  .map(p => p.split('='))
  .reduce((obj, pair) => {
    const [key, value] = pair.map(decodeURIComponent);
    obj[key] = value;
    return obj;
  }, {});

一个简单的答案是内置本地Node模块。(没有第三方npm模块)

querystring模块提供了解析和格式化URL查询字符串的实用程序。可以使用以下方法访问:

const querystring = require('querystring');

const body = "abc=foo&def=%5Basf%5D&xyz=5"
const parseJSON = querystring.parse(body);
console.log(parseJSON);

在2021年…请认为这是过时的。

Edit

这个编辑改进并解释了基于评论的答案。

var search = location.search.substring(1);
JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')

例子

分五个步骤解析abc=foo&def=%5Basf%5D&xyz=5:

decodeURI: abc = foo&def = xyz (asf) = 5 转义引号:相同，因为没有引号 替换&:abc=foo"，"def=[asf]"，"xyz=5 " 5 . Replace =: abc":"foo"，"def":"[asf]"，"xyz": Suround卷曲和引用:{“abc”:“foo”、“def”:“(asf)”,“xyz”:“5”}

这是合法的JSON。

改进的解决方案允许搜索字符串中有更多字符。它使用了一个恢复函数来进行URI解码:

var search = location.search.substring(1);
JSON.parse('{"' + search.replace(/&/g, '","').replace(/=/g,'":"') + '"}', function(key, value) { return key===""?value:decodeURIComponent(value) })

例子

search = "abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar";

给了

Object {abc: "foo", def: "[asf]", xyz: "5", foo: "b=ar"}

原来的答案

一行程序:

JSON.parse('{"' + decodeURI("abc=foo&def=%5Basf%5D&xyz=5".replace(/&/g, "\",\"").replace(/=/g,"\":\"")) + '"}')

首先你需要定义什么是get变量:

function getVar()
{
    this.length = 0;
    this.keys = [];
    this.push = function(key, value)
    {
        if(key=="") key = this.length++;
        this[key] = value;
        this.keys.push(key);
        return this[key];
    }
}

而不是直接读:

function urlElement()
{
    var thisPrototype = window.location;
    for(var prototypeI in thisPrototype) this[prototypeI] = thisPrototype[prototypeI];
    this.Variables = new getVar();
    if(!this.search) return this;
    var variables = this.search.replace(/\?/g,'').split('&');
    for(var varI=0; varI<variables.length; varI++)
    {
        var nameval = variables[varI].split('=');
        var name = nameval[0].replace(/\]/g,'').split('[');
        var pVariable = this.Variables;
        for(var nameI=0;nameI<name.length;nameI++)
        {
            if(name.length-1==nameI) pVariable.push(name[nameI],nameval[1]);
            else var pVariable = (typeof pVariable[name[nameI]] != 'object')? pVariable.push(name[nameI],new getVar()) : pVariable[name[nameI]];
        }
    }
}

并使用like:

var mlocation = new urlElement();
mlocation = mlocation.Variables;
for(var key=0;key<mlocation.keys.length;key++)
{
    console.log(key);
    console.log(mlocation[mlocation.keys[key]];
}

/** * Parses and builds Object of URL query string. * @param {string} query The URL query string. * @return {!Object<string, string>} */ function parseQueryString(query) { if (!query) { return {}; } return (/^[?#]/.test(query) ? query.slice(1) : query) .split('&') .reduce((params, param) => { const item = param.split('='); const key = decodeURIComponent(item[0] || ''); const value = decodeURIComponent(item[1] || ''); if (key) { params[key] = value; } return params; }, {}); } console.log(parseQueryString('?v=MFa9pvnVe0w&ku=user&from=89&aw=1')) see log
