对Sameer的回答略有改进，将参数缓存为闭包，以避免每次调用时解析和遍历所有参数

var getURLParam = (function() {
    var paramStr = decodeURIComponent(window.location.search).substring(1);
    var paramSegs = paramStr.split('&');
    var params = [];
    for(var i = 0; i < paramSegs.length; i++) {
        var paramSeg = paramSegs[i].split('=');
        params[paramSeg[0]] = paramSeg[1];
    }
    console.log(params);
    return function(key) {
        return params[key];
    }
})();

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

只是想展示一下我的代码:

function (name) {
  name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
  var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
  results = regex.exec(location.search);
  return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));

}

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>

还有一个使用URI.js库的例子。

例子准确地回答了所问的问题。

var url = 'http://example.com?sent=yes'; var urlParams = new URI(url).search(true); // 1. Does sent exist? var sendExists = urlParams.sent !== undefined; // 2. Is it equal to "yes"? var sendIsEqualtToYes = urlParams.sent == 'yes'; // output results in readable form // not required for production if (sendExists) { console.log('Url has "sent" param, its value is "' + urlParams.sent + '"'); if (urlParams.sent == 'yes') { console.log('"Sent" param is equal to "yes"'); } else { console.log('"Sent" param is not equal to "yes"'); } } else { console.log('Url hasn\'t "sent" param'); } <script src="https://cdnjs.cloudflare.com/ajax/libs/URI.js/1.18.2/URI.min.js"></script>

试试这个工作演示http://jsfiddle.net/xy7cX/

火:

inArray: http://api.jquery.com/jQuery.inArray/

这应该会有帮助:)

code

var url = "http://myurl.com?sent=yes"

var pieces = url.split("?");
alert(pieces[1] + " ===== " + $.inArray("sent=yes", pieces));
