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：

http://www.developerdrive.com/2013/08/turning-the-querystring-into-a-json-object-using-javascript/

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();

以下是我所做的：

var uriParams = getSearchParameters();
alert(uriParams.c);


// background functions:

// Get object/associative array of URL parameters
function getSearchParameters () {
  var prmstr = window.location.search.substr(1);
  return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}

// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
  var params = {},
      prmarr = prmstr.split("&");

  for (var i = 0; i < prmarr.length; i++) {
    var tmparr = prmarr[i].split("=");
    params[tmparr[0]] = tmparr[1];
  }
  return params;
}

window.location.search.slice(1).split('&').reduce((res, val) => ({...res, [val.split('=')[0]]: val.split('=')[1]}), {})

来源

function gup( name, url ) {
    if (!url) url = location.href;
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( url );
    return results == null ? null : results[1];
}
gup('q', 'hxxp://example.com/?q=abc')

您可以在location.search中获取查询字符串，然后可以分割问号后的所有内容：

var params = {};

if (location.search) {
    var parts = location.search.substring(1).split('&');

    for (var i = 0; i < parts.length; i++) {
        var nv = parts[i].split('=');
        if (!nv[0]) continue;
        params[nv[0]] = nv[1] || true;
    }
}

// Now you can get the parameters you want like so:
var abc = params.abc;

以下是用于将url查询参数解析为Object的angularJs源代码：

函数tryDecodeURIComponent（值）{尝试{返回decodeURIComponent（value）；}捕获（e）{//忽略任何无效的uri组件}}函数isDefined（value）｛return typeof value！==“undefined”；｝函数parseKeyValue（keyValue）{keyValue=keyValue.replace（/^\？/，“”）；var obj={}，key_value，key；var iter=（keyValue||“”）.split（'&'）；对于（var i=0；i<iter.length；i++）{var kV值=iter[i]；if（kV值）{key_value=kV值。替换（/\+/g，“%20”）。拆分（“=”）；key=tryDecodeURIComponent（key_value[0]）；if（isDefined（键））{var val=isDefined（key_value[1]）？tryDecodeURIComponent（key_value[1]）：true；if（！hasOwnProperty.call（obj，key））{obj[key]=val；}else-if（isArray（obj[key]））{obj[key].push（val）；}其他{obj[key]=[obj[key]，val]；}}}};返回obj；}警报（JSON.stringify（parseKeyValue（'？a=1&b=3&c=m2-m3-m4-m5'）））；

您可以将此函数添加到window.location：

window.location.query = function query(arg){
  q = parseKeyValue(this.search);
  if (!isDefined(arg)) {
    return q;
  }      
  if (q.hasOwnProperty(arg)) {
    return q[arg];
  } else {
    return "";
  }
}

// assuming you have this url :
// http://www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5

console.log(window.location.query())

// Object {a: "1", b: "3", c: "m2-m3-m4-m5"}

console.log(window.location.query('c'))

// "m2-m3-m4-m5"
