function executeRequest(req) { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { // Typical action to be performed when the document is ready: document.getElementById("response").value = xhttp.responseText; } }; xhttp.open("POST", "execute/cardbrowser", true); xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xhttp.send("lorem=ipsum&name=binny"); }
服务器:
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { System.out.println(req.getParameter("lorem"));}
