如何在没有jQuery的情况下从JavaScript对象获取查询字符串? [英] How to get query string from JavaScript Object without jQuery?

问题描述

我正在寻找jQuery.param()的无依赖实现.我正在尝试创建一个数组或对象的序列化表示形式，以适合在URL查询字符串或Ajax请求中使用，而无需使用jQuery.

I'm looking for an dependency-free implementation of jQuery.param(). I'm trying to create a serialized representation of an array or object, suitable for use in a URL query string or Ajax request, without using jQuery.

我搜索了一段时间，但每个人似乎都在使用$ .param()...

I searched for some time now, but everyone just seems to use $.param()...

提前谢谢！

I found the best and optimal way on How to get query string values using JavaScript. Checkout the below example to fetch the query string.

var queryString = window.location.search || '';
var keyValPairs = [];
var params      = {};
queryString     = queryString.substr(1);

if (queryString.length)
{
   keyValPairs = queryString.split('&');
   for (pairNum in keyValPairs)
   {
      var key = keyValPairs[pairNum].split('=')[0];
      if (!key.length) continue;
      if (typeof params[key] === 'undefined')
         params[key] = [];
      params[key].push(keyValPairs[pairNum].split('=')[1]);
   }
}

上面脚本的用法

//url=http://stackoverflow.com/how-to-get-query-string-values-in-javascript?query=123&list=default
params['query'];
//Output ["123"]

params['list'];
//Output ["default"]

//Note: If the query string value is empty the method will return the value as empty string.
