Something like this will create a closure which will store your original HREFproperty:
像这样的事情会创建一个闭包来存储你的原始HREF属性：
function init() {
var link = document.getElementById("link");
var hrefOrig = link.href;
var dd = document.getElementById("DropDown");
dd.onchange = function(){ link.href = hrefOrig + dd.value; }
}
window.addEventListener("load", init, false); // for Firefox; for IE, try window.attachEvent

JavaScript:

document.links["link"].href += myvariable;
jQuery:
jQuery：
$('#link').attr('href', $('#link').attr('href') + myvariable);
