Editor to share with you how to use Ajax to achieve the value in the script, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Page script:

Function ajaxSave (URLS) {/ / defines a variable to hold the XMLHttpRequest object var xmlhttp; / / defines a variable to store the response results returned from the server var responseContext = ""; if (window.XMLHttpRequest) {/ / code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp = new XMLHttpRequest ();} else {/ / code for IE6, IE5 xmlhttp = new ActiveXObject ("Microsoft.XMLHTTP") } xmlhttp.onreadystatechange = function () {if (xmlhttp.readyState = = 4 & & xmlhttp.status = = 200) {responseContext = xmlhttp.responseText; alert (responseContext);}} xmlhttp.open ("POST", URLS, true); xmlhttp.setRequestHeader ("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.send ();}

Background method:

Boolean boolean1; String reponseText= "; if (boolean1) {reponseText=" saved successfully! " ;} else {reponseText= "Save failed!" ;} HttpServletResponse response = ServletActionContext.getResponse (); response.setContentType ("text/plain"); response.setCharacterEncoding ("UTF-8"); PrintWriter out = response.getWriter (); out.println (reponseText); out.flush (); out.close (); return null; is all the content of the article "how to use Ajax to pass values in a script".
