对于Node JS，你可以使用Node JS API querystring:

const querystring = require('querystring');

querystring.parse('abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar');
// returns the object

文档:https://nodejs.org/api/querystring.html

这是一个简单的版本，显然你需要添加一些错误检查:

var obj = {};
var pairs = queryString.split('&');
for(i in pairs){
    var split = pairs[i].split('=');
    obj[decodeURIComponent(split[0])] = decodeURIComponent(split[1]);
}

我发现$. string .deparam是最完整的预构建解决方案(可以做嵌套对象等)。查看文档。

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;
   });

一个班轮。干净简单。

const params = Object.fromEntries(new URLSearchParams(location.search));

对于您的具体情况，它将是:

const str = 'abc=foo&def=%5Basf%5D&xyz=5'; const params = Object.fromEntries(new URLSearchParams(str)); console.log (params);

使用URLSearchParams JavaScript Web API非常简单，

var paramsString = "abc=foo&def=%5Basf%5D&xyz=5"; //returns an iterator object var searchParams = new URLSearchParams(paramsString); //Usage for (let p of searchParams) { console.log(p); } //Get the query strings console.log(searchParams.toString()); //You can also pass in objects var paramsObject = {abc:"forum",def:"%5Basf%5D",xyz:"5"} //returns an iterator object var searchParams = new URLSearchParams(paramsObject); //Usage for (let p of searchParams) { console.log(p); } //Get the query strings console.log(searchParams.toString());
