JavaScript - Javascript Httprequest And Response
Hi Guys,
I am having a small problem in my Javascript when I am using HTTPRequest. I am unable to recieve my Response back from server (Java Servlet) in time. I am using following code; Code: // Following function will simply goes to the Server and check if provided class is present function verifyClass(clsName) { var url = "checkServlet?className=" + clsName; var chkResult = ""; var httpReq = null; // Create an ActiVEX control object according to BRowser we are using httpReq = GetXmlHttpObject(); if (httpReq == null) { alert ("AJAX Request Failed!!! - Your browser does not support AJAX - Skipping CLASS Check."); } else { // First prepare ourself to recieve a response from server // Following code will simply wait untill server finish its response httpReq.onreadystatechange = function(){ if(httpReq.readyState == 4){ chkResult = httpReq.responseText; } } // Setup a request parameters httpReq.open("GET", url, true); // Send the request httpReq.send(null); } // Return the response recieved return chkResult; } I am using FireBug (plugin with my Firefox) to debug the HTML and I can see the response in it but when I am putting 'alert' before return the variable 'chkResult' is empty. Your suggestion will be appreciated; Thanks, -- SJunejo Similar Tutorialsi have a drop down which triggers a ajax call. The ajax response is a form with various fields depending upon the drop down option selected. I have a text field in that response form which is to input the date. i have a calender widget and wish to display that as a popup with an onfocus or onclick on that text field. But becoz of the ajax response it does not let me do it. I know the problem is in the creation and destruction of the element where the calender has to be displayed so i tried putting the callender intiialization function in another function and calling that onclick but id doesnt work. below is my modified javascript code for the initialization of the calendar. Code: <script type="text/javascript"> var calendar1, calendar2, calendar3; /*must be declared in global scope*/ /*put the calendar initializations in the window's onload() method*/ function cal_init() { alert("hi"); calendar1 = new Epoch('cal1','popup',document.getElementById('calendar1_container'),false); calendar2 = new Epoch('cal1','popup',document.getElementById('calendar2_container'),false); calendar3 = new Epoch('cal1','popup',document.getElementById('calendar3_container'),false); }; </script> Hey guys, I am doing a website and the way it is suppose to work is when you click on a link there is a little triangle beside it, so when you click on it the triangle is suppose to face down but more links appear when you click on it. Anyways here is the code if someone could please tell me what im doing wrong? HTML Code: <ul class="menu" id="subnavmenu"> <li><a href="#" onClick="showHide('sublist1');return false;" id="subheading">About Us</a> <ul id="sublist1" style="display:none;"> <li><a href="#">Visit Us</a></li> <li><a href="#">Contact Us</a></li> <li><a href="#">Archives Unboxed and Revealed</a></li> </li> </ul> CSS Code: #subnavmenu ul.menu { display: block; overflow:hidden; } JAVASCRIPT Code: function showHide(element_id) { if (document.getElementById && document.getElementById(element_id) && document.getElementById(element_id).style) { var menu = document.getElementById(element_id); var arrow = document.getElementById(element_id + '_arrow'); if (menu.style.display == "block") { menu.style.display = "none"; if (arrow.src) { arrow.src = arrow.src.replace("down","right"); } } else { menu.style.display = "block"; if (arrow.src) { arrow.src = arrow.src.replace("right","down"); } } } } hi, At the moment when I select a county from the dropdown list, they show in the <div id="ajaxDiv"> - HttpRequest is loading apage, I'd like to do this with the pagination?!

Particularly, how do I get down to the value at each node?How do I traverse the XML document using JS? Is this (using XML) better than JSON (other than the obvious platform-independence)? Which is better? Thanks! Hi all, I'm new to php, but managed to get a domail.php working. My form from my html website is sent by the php file to my email address. However, the php echoes a mailresult upon successful sending, but how can I let my website respond to this mailresult?? I'd like to go to a different page, when the mailresult==OK, so something in my html file like if($mailResult==OK){ //go to page saying, your mail has been sent! } OR I could change the "OK" to something more like "Thank you, your mail has been received" in the php file, because this text IS shown in my browser window. Then I would need to know how to make the layout of the window saying this fit my website layout, because now the text is just in a white plain frame.. Hope you guys can help me with either of those two options. Thanks a ton!! Jay Hello, Im just starting out with java script. I have written the following statement, and for some reason it does not follow up beyond the prompt command. As i type in yes or no - the screen empties. Id be happy if you could tell me where i had gone wrong. My guess its something about the syntax. <!DOCTYPE html> <html> <title>ex</title> <head> <script> var question1 = prompt("do you want to hear a story?"); if (question1 = "yes") {console.log ("once upon a time there was a dragon");} else { console.log ("Maybe listen to a little music?");} </script> </head> <body></body> </html> I have the following files in the same directory.

I am a new to javascript. Is there a way to get my array data from the response object. Please help. I'm make a ajax call to a processing PHP file that echos either "success" or an "error message". When the success is returning, i want Jquery to recognize this and then redirect the browsers instead of displaying the success message. Here are some snippets. I can only seem to parse to a blank or null. Jquery code: Code: $.ajax({ type: "POST", url: "process.php", data: wfLoginPost(), success: function(msg){ alert(msg); // both below are either null or blank //var res = $(msg).find("span.response").text(); //var res = $(msg).find("span.response").html(); if(res == 'Success'){ window.location = 'http://www.google.com'; } } }); process.php PHP Code: if($qry[0]['pwd'] == $password){ echo "<span class='response'>Success</span>"; }else{ echo "<span class='response'>Username or password did not match</span>"; } Here is the contents of the msg response from the ajax post: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" type="text/css" href="css/reset.css"/> <link rel="stylesheet" type="text/css" href="css/960grid.css"/> <link rel="stylesheet" type="text/css" href="css/style.css"/> <link rel="stylesheet" type="text/css" href="css/statusmessageQ.css"/> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" src="js/jquery.statusmessageQ-0.5.js"></script> </head> <span class='response'>Success</span> long story short, I have been trying to run a loop, say, 10 times and I know the result I want will be on the first request but it sends all 10 at the same time, over writing the variable for xmlhttp. discovering in my days of attempts that its just the nature of the beast, but I would like ANY way possible to get a response on the 1st pass of the loop in any way possible. But for now, here's a riddle I can't solve, how to make this function return with the response? Code: function ajaxRequest(query){ var response = 'I have not checked yet.'; var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { response = xmlhttp.responseText.trim(); } } xmlhttp.open("GET",query,true); xmlhttp.send(); return response; } It will always instantly say "I have not checked yet." when I would like the response. I'm okay with it being a 2-5 second delay as long as it doesn't pause the browser like a synchronous request. Even a delay of some sort just before the return would probably do it. In that case, I think I can get the rest. Thanks much in advance! I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please?
