从字符串中获取参数:

Object.defineProperty(String.prototype, 'urlParam', {

    value: function (param) {

    "use strict";

    var str = this.trim();

    var regex = "[\?&]" + param + "=([^&#]*)";

    var results = new RegExp(regex, "i").exec(str);

    return (results !== null) ? results[1] : '';

    }
});

使用方法:

var src = 'http://your-url.com/?param=value'

console.log(src.urlParam(param)); // returns 'value'

使用这个

$.urlParam = function(name) {
  var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
  return results[1] || 0;
}

我用了这个，很管用。 http://codesheet.org/codesheet/NF246Tzs

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


var first = getUrlVars()["id"];

如此简单，你可以使用任何url和获取价值

function getParameterByName(name, url) {
    if (!url) url = window.location.href;
    name = name.replace(/[\[\]]/g, "\\$&");
    var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
    results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, " "));
}

使用的例子

// query string: ?first=value1&second=&value2
var foo = getParameterByName('first'); // "value1"
var bar = getParameterByName('second'); // "value2" 

注意:如果一个参数出现了几次(?first=value1&second=value2)，你将得到第一个值(value1)和第二个值(value2)。

我希望使用完整的简单REG Exp

  function getQueryString1(param) {
    return decodeURIComponent(
        (location.search.match(RegExp("[?|&]"+param+'=(.+?)(&|$)'))||[,null])[1]
    );
  }

这可能有点过分了，但是现在有一个非常流行的用于解析uri的库，叫做URI.js。

例子

var uri = "http://example.org/foo.html?technology=jquery&technology=css&blog=stackoverflow"; var components = URI.parse(uri); var query = URI.parseQuery(components['query']); document.getElementById("result").innerHTML = "URI = " + uri; document.getElementById("result").innerHTML += "<br>technology = " + query['technology']; // If you look in your console, you will see that this library generates a JS array for multi-valued queries! console.log(query['technology']); console.log(query['blog']); <script src="https://cdnjs.cloudflare.com/ajax/libs/URI.js/1.17.0/URI.min.js"></script> <span id="result"></span>
