使用 Javascript 添加 Html URL 参数

Question

只需要一个像这样的 html url 中的可变参数：

mywebpage.com/something.html?width=(Parameter1)&height=(Parameter2)

但在该网页的内容中，我想添加以下内容：

<script>fid="example"; width=(Parameter1); height=(Parameter2);</script>

我怎样才能只使用 javascript 和 Html 来做到这一点

这是类似问题 (How to get the value from the GET parameters?) 建议的代码

var QueryString = function () {
  // This function is anonymous, is executed immediately and 
  // the return value is assigned to QueryString!
  var query_string = {};
  var query = window.location.search.substring(1);
  var vars = query.split("&");
  for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
        // If first entry with this name
    if (typeof query_string[pair[0]] === "undefined") {
      query_string[pair[0]] = pair[1];
        // If second entry with this name
    } else if (typeof query_string[pair[0]] === "string") {
      var arr = [ query_string[pair[0]], pair[1] ];
      query_string[pair[0]] = arr;
        // If third or later entry with this name
    } else {
      query_string[pair[0]].push(pair[1]);
    }
  } 
    return query_string;
} ();

只要变量列表有些固定且数量很少，请保持简单。

HTML：

<a href="#" id="some-link-id>Click me!</a>

JS：

var width = 100;
var height = 100;

var link  = document.getElementById('some-link-id');
var url   = "http://mywebpage.com/page.html?width=" + width + "&height=" + height;
link.href = url;

或者要更新您所在页面的 URL，只需设置window.location.href

var width = 100;
var height = 100;

var url = "http://mywebpage.com/page.html?width=" + width + "&height=" + height;
window.location.href = url;
