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];
    }
})();

jQuery代码片段，以获取动态变量存储在url作为参数，并将它们存储为JavaScript变量，以供您的脚本使用:

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

example.com ? param1 = name&param2 = id = 6

$.urlParam('param1'); // name
$.urlParam('id');        // 6
$.urlParam('param2');   // null

带有空格的参数示例

http://www.jquery4u.com?city=Gold Coast
console.log($.urlParam('city'));  
//output: Gold%20Coast



console.log(decodeURIComponent($.urlParam('city'))); 
//output: Gold Coast

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>

函数GetRequestParam(参数) ｛ Var res = null; 尝试{ var qs = decodeURIComponent(window.location.search.substring(1));//获取then之后的所有内容'?URI中的' Var ar = q .split('&'); 美元。Each (ar, function(a, b){ Var kv = b.split('='); If (param === kv[0]){ Res = kv[1]; 返回false;//打破循环 ｝ })； }捕捉(e) {} 返回res; ｝

使用URLSearchParams:

var params = new window.URLSearchParams(window.location.search);
console.log(params.get('name'));

注意兼容性(大多数情况下是好的，但IE和Edge，可能是不同的故事，检查这个兼容性参考:https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams)

使用这个

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