Can't Call The Servlet Using AJAX

Jul 18, 2006

I create some javascript to send some search request. However, on some machines i wont' be able to send request. What could be the reason?

function sendSearchRequest()
{
var srch_url = "/servlet/Search";
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = null;
}
}
}

request.open('GET', srch_url , true );
request.onreadystatechange = GetSearchResponse;
request.send(null);
}

function GetSearchResponse()
{}

Ajax With Servlet

Dec 10, 2005

I am trying to call a servlet i created. Basically this servlet will let user create a new account at the server. I have created the function "CreateAccount()" but http_request.readyState always return me 0.

What is wrong with my code?

function CreateAccount()
{
if( window.XMLHttpRequest )
{
http_request = new XMLHttpRequest();
}
else if( window.ActiveXObject )
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
var parameters = "username=" + encodeURI(
document.getElementById("username").value ) +
"&password=" + encodeURI(
document.getElementById("password").value );

http_request.onreadystatechange = RegisterUser();
http_request.open('post', "/servlet/CreateUserAccount", true );
http_request.setRequestHeader("Content-type",
"application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);

}
}

function RegisterUser()
{
alert( "register user: " + http_request.readyState );
if( http_request.readyState == 4 )
{
if( http_request.status == 200 )
{
alert( http_request.responseText );
}
else
{

}
}
}

AJAX :: Call Based On Results Of A Previous Call

Dec 14, 2010

The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.

Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.

I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)

var validateOK=true;
if (typeof validate !='undefined')
validateOK = validate(document.EditForm);

if (validateOK==true) {
theAction = document.EditForm.action;
if ( theAction.indexOf('?') == -1 ) {
if ( theAction.indexOf('#') == -1 ) {
document.EditForm.action = theAction + "?__haction=apply"
} else {
posit = theAction.indexOf('#')
document.EditForm.action = theAction.substring(0,posit) +
"?__haction=apply" + theAction.substring(posit,theAction.length)
}
} else {
posit = theAction.indexOf('?')
document.EditForm.action = theAction.substring(0,posit+1) +
"__haction=apply&" + theAction.substring(posit+1,theAction.length)
}
document.EditForm.submit();
}

JQuery :: Passing The JSON Data From Servlet?

Dec 30, 2011

I am working on a servlet. I am obtaining the JSON data and I want to pass it to the jQuery to construct and display the table out of it.

Everytime the servlet posts a request, it gets the JSON data, and i want to display that as a chart and table using javaScript. For that I need to know how to pass the json data parameter to a jQuery from servlet.

Example :

String jsonData = {"key":"value"};
out.println("<input type="button" id="chart" onclick=function(jsonData)>");

Where function(parameter) is the jQuery function.

IE Vs. Firefox: Delay In Receiving Response From Servlet Using IFrame

Feb 6, 2007

when I use Firefox to run my application (this involves
sending an IFRAME request to the servlet and handling the response),
there is no delay in displaying the data after each response. But when
I use IE, there seems to be a 1-2 second delay. The script sends a
request using IFrame, goes through a loop to return script tags
containing data to the browser, and then data is displayed by the
browser and a new request is sent. For IE, when a new request is sent,
the delay in receiving the response is quite noticeable.

Ajax Call Not Working

webservice returns a Dataset that contains various customer details

But my ajax call is not working.

My ajax call is something like:

AJAX :: Checking DOM After Call?

Jul 31, 2010

I'm having a problem where a button no longer triggers an event after I changed it through an AJAX call.Problem is, once AJAX has updated the DIV, the contents in RAM is different from what I see when I check the page source (CTRL-U in FireFox/Chrome).What tools are there to display the current contents of the DOM? I generally prefer to use Chrome/Iron, but if there are better tools for Firefox, I'm also interested.

AJAX :: Pass Value To Call?

I'm admittedly a novice when it comes to AJAX. I can get stuff to work, typically, but really have no idea what's going on. I copied the original code from another source.

Now, something a bit more complicated is coming up and I can't get it to work.

Here's the script I'm using to start; the one that I typically use that works fine code...

AJAX :: Call That Works In FF Not IE?

Jun 23, 2011

This code updates a feedback box every 5 seconds. Web page:

<body onload="fback();setInterval('fback()',5000);">(declared firstly so that you don't end up with a blank space for 5 seconds when the page loads.) This calls an XMLHttp request to feedback.php.

xmlhttp_fb.open("GET","feedback.php",true); The php page queries a table and returns one item from about 360 records by randomly choosing a UniqueID between 1 and the last row. I deliberately chose this because it's quicker than querying them all once and working through an array.

[Code]...

Enough code to give you the idea I hope. $max is the last row of the feedback table. (Found by ORDER DESC)

This works great in Firefox and Chrome but not IE7 or 8. Really can't think why because there are no setInterval issues that I know of.

JQuery :: Call Ajax Function Inside Another Ajax Function?

Oct 12, 2010

I am using jquery for getting ajax responses from server side functions.

I am in a situation where I need to make two ajax calls one after another and the second one is dependent on the response of the first one.

I have tried to use a code which is similar to this one?

$.ajax({
type: 'GET',
url: 'myURL',
success: function(data)

[Code]....

Is it possible to get two have two ajax calls , one dependent on the other?
