以json形式从window.location中的搜索对象中提取所有url参数

export const getURLParams = location => {
    const searchParams = new URLSearchParams(location.search)
    const params = {}

    for (let key of searchParams.keys()) {
        params[key] = searchParams.get(key)
    }

    return params
}

console.log(getURLParams({ search: '?query=someting&anotherquery=anotherthing' }))

// --> {query: "someting", anotherquery: "anotherthing"}

我很早以前就发现了这一点，非常简单：

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi,    
    function(m,key,value) {
      vars[key] = value;
    });
    return vars;
  }

然后这样称呼：

var fType = getUrlVars()["type"];

function parseUrl(url){
    let urlParam = url.split("?")[1];
    console.log("---------> URL param : " + urlParam);
    urlParam = urlParam.split("&");
    let urlParamObject = {};
    for(let i=0;i < urlParam.length;i++){
        let tmp = urlParam[i].split("=");
        urlParamObject[tmp[0]] = tmp[1];
    }
    return urlParamObject;
}

let param = parseUrl(url);
param.a // output 10
param.b // output 20

一个内衬和IE11友好：

> (window.location.href).match('c=([^&]*)')[1]
> "m2-m3-m4-m5"

我使用parseUri库。它允许您完全按照您的要求进行操作：

var uri = 'www.test.com/t.html&a=1&b=3&c=m2-m3-m4-m5';
var c = uri.queryKey['c'];
// c = 'm2-m3-m4-m5'

您可以添加一个输入框，然后要求用户将值复制到其中……这非常简单：

<h1>Hey User! Can you please copy the value out of the location bar where it says like, &m=2? Thanks! And then, if you could...paste it in the box below and click the Done button?</h1>
<input type='text' id='the-url-value' />
<input type='button' value='This is the Done button. Click here after you do all that other stuff I wrote.' />

<script>
//...read the value on click

好吧，但说真的。。。我发现了这段代码，它似乎很有用：

function queryToJSON() {
    var pairs = location.search.slice(1).split('&');

    var result = {};
    pairs.forEach(function(pair) {
        pair = pair.split('=');
        result[pair[0]] = decodeURIComponent(pair[1] || '');
    });

    return JSON.parse(JSON.stringify(result));
}

var query = queryToJSON();
