JavaScript - Javascript Datetime Handling

Hi I am using httpXmlRequest object to call a xml web service. In order to successfully perform a task there are couple steps need to happen.

1 you have to request for a session (cookie)
2 with the cookie, we need to authenticate with the server
3 then perform other actions

snippet of my code looks something like this. Basically here i am trying to get the cookie, login and then logout once logged in.

function connect() {
document.myForm.elements['myTextArea'].value += "connecting to teh server.\n";
try {
xhttp.open("GET",urlStr + commonInfoParam, true);
xhttp.send();
xmlDoc = xhttp.responseXML;
xmlDoc.onreadystatechange = function () {
if(xmlDoc.readyState == 4) {
var resultsTag = null;
resultsTag = xmlDoc.getElementsByTagName("results");

if(resultsTag != null) {
for(i=0;i<resultsTag.length;i++) {
var commonTag = resultsTag[i].getElementsByTagName("common");
for(j=0;j<commonTag.length; j++) {
cookie = commonTag[j].getElementsByTagName("cookie")[0].childNodes[0].nodeValue;
break;
}
}
}
if(cookie != null) {
document.myForm.elements['myTextArea'].value += "cookie found: " + cookie + "\n";
login();
}
}
};
} catch(e) {
document.myForm.elements['myTextArea'].value += "Exception occurred at connect: " + e.message + "\n";
}
}




function login() {
var loginRequestURL = "http://testconnect.com/api/xml?action=login&login=" + username+ "&password=" + password + "&session=" + cookie;
try {
xhttp.open("GET", loginRequestURL, true);
xhttp.send();
xmlDoc = xhttp.responseXML;
xmlDoc.onreadystatechange = function () {
alert('in loginResponseHandler');
if(xmlDoc.readyState == 4) {
try {
loginStatus = xmlDoc.documentElement.childNodes[0].attributes.getNamedItem("code").nodeValue;
if(loginStatus == 'ok') {
alert("login is good: " + loginStatus);
logout();
} else {
}
} catch(e) {}
}
};
} catch(e) {
}
}




function logout() {
alert("in logout");
try {
xhttp.open("GET", logoutRequestURL + cookie, true);
xhttp.send();
xmlDoc = xhttp.responseXML;
xmlDoc.onreadystatechange = function () {
alert("in logoutResponseHandler");
if(xmlDoc.readyState == 4) {
try {
status = xmlDoc.documentElement.childNodes[0].attributes.getNamedItem("code").nodeValue;
if(status == 'ok') {
alert(status);
}
} catch(e) {}
}
};
}
catch(e) {}
}


so when I run my code in the browser, all my alert stages give me proper message as expected. But at the final alert, it hangs. I just could not figvure out what am i doing wrong. can any one pin point this out for me please?

Thanks in advance.

Hi,

I think the problem I am having is an event not a css issue, so I hope I posted in the right forum.

What I am trying to achieve is the capability to provide multiple instant chat messages. I have the php/ajax for the instant messages, what I am not sure is how to be able to view multiple chats.

What I have started to do is limit it to five possible instant chat messages and have five divs in place with visibility hidden. It works fine for one.

But if someone clicks on the name of a person they wish to chat with, the way I am currently doing it, I would need to find out:
1. which divs were free to start an instant chat in (I have no idea how to do this with divs)?
2. Having identified it I will need to change the visibility so it suddenly becomes visible

I guess firstly am I going about this the right way to be able to host/view multiple chats?

My code is below.

If I have left anything out which might be helpful please let me know. I just got stuck on the logistics side of figuring out how was the best way to make this happen, any pointers would be great.

I can get this code to take two separate sections of a file which are not beside each other and write them into another file. It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help?

Code:

 try{                    
               while (in.hasNextLine())
               {
                  String line = in.nextLine();
                  out.println( line);
                  int i=0;
                  if(!Character.isDigit(line.charAt(i)))  { i++; }
                  studentStringNumber = line.substring(0, i);
                  String stringResult = line.substring(i);
                              	
                  studentStringNumber = studentStringNumber.trim();
                  stringResults = stringResults.trim();
                  double stringResultsValue = Double.parseDouble(stringResults.trim());
                  stringResults = in.nextLine();
                              	
                                 
                  studentStringNumber = in.nextLine();
                  studentNumber = Integer.parseInt(studentStringNumber);
                  if(in.hasNextInt())
                  {
                     int value = in.nextInt();
                  }
               						 					   
                  results = Double.parseDouble(stringResults); 
                  if(in.hasNextDouble())
                  {
                     double value = in.nextDouble();
                  } 
               						               	
                            	
                  Scanner lineScanner = new Scanner(line);
                  studentStringNumber = lineScanner.next();
                  while(!lineScanner.hasNextDouble())
                  {
                     studentStringNumber = studentStringNumber+ " " +lineScanner.next();
                  }
                  stringResultsValue = lineScanner.nextDouble();     
               }
            }

Hi everyone;
I have created a JavaScript function to show either a enabled or a disabled text input field depending on whether a checkbox has been clicked or not. It works great for that purpose. However, when I use it for more than one text input field and I submit the form, it goes back to its disabled form. This is a problem if you by mistake submit the form without filling all the fields. As I said, the submit button makes the form go disabled. Is there a way to either not have the form go disabled after submission or to have a "Oncheck" function so I can use $_SESSION to keep the checked attribute?
Thanks in advance for all your help

if (document.getElementById("checkbox").checked == true) {

$test = $_POST['test'];

$test2 = $_POST['test2'];
$_SESSION = $_POST['test2'];

I've used js only for simple form validations thus far. I've been working on a coldfusion/ajax dynamic select list for a few days and just about have it functioning the way I want it.

My question is this. Whats the best way, if any, to handle users who turn js off. What I mean is, I have so far three separate queries for my three select lists, and are populated with ajax calls. Is there a way to get the same functionality with standard queries and page refreshes in case a visitor does have js disabled?

Thanks for any tips and advice.
