function makeRequest(sUrl, oParams) {
  for (sName in oParams) {
    if (sUrl.indexOf("?") > -1) {
      sUrl += "&";
    } else {
      sUrl += "?";
    }
    sUrl += encodeURIComponent(sName) + "=" + encodeURIComponent(oParams[sName]);

  document.body.appendChild(oScript);
}

This function expects to be passed a URL for a JavaScript file and an object containing query string arguments. The query string is constructed inside of the function by iterating over the properties of this object. Then, the familiar dynamic script loading technique is used. This function can be called as follows:

var oParams = {
  "param1": "value1",
  "param2": "value2"
};
makeRequest("/path/to/myjs.php", oParams)
