this is mohan started working recently on ajax with struts2 framework. I can able to make a ajax request to an struts2 action class.But in the response I am getting the whole jsp page as a response mentioned in the result tag in struts.xml file.But I need only the partial data like array or list etc from the action class.
View 2 RepliesThis may be a post for the struts list, but I'll start her. I'm using Jquery with Struts2 and SiteMesh. My tabs work fine with all my code on a single JSP. I tried switching to AJAX, but that breaks the OGNL reference to a list on the second TAB. I set-up a separate namespace in Struts so that I could exclude the pages from SiteMesh.
My tabs looked like this:
I have a situation where I want to send data, but I have no need for a
response. It seems to me that XMLHTTPRequest is the best way to send the
data, but I don't need any response back from the server.
Basically, I'm writing js errors to an error log on the server side -
and there is no need to inform the user that the error has been logged.
The problem is that I don't want to sit with the request open & waiting
for a response, when I have no need for the response. I suppose I could
have the server respond with just "OK" or something like that, but it's
really not relevant
I was thinking of just aborting the request on readystate=1 (at that
point, the server-side script should have executed already, right?), but
I was wondering if there were any other methods to JUST send..
Is it possible to upload FILE from form by AJAX ? I capture values on form field and send by ajax call and all works perfect, but when i try upload file it doesn'work. Maybe wron header is set? What do you think of that?
View 2 Replies View RelatedI have a problem with sending data from a form to a php script with AJAX. To test if it works, I try to send data from the form, print it in the php with "echo", and then put it back in the initial html file.
My Javascript code is:
The function stateChanged, basically says:
The problem is that the response is empty, but I don't know why. I have checked the input data and the postData variable says "firstName="+input (e.g. "firstName=Robert"), so that's not the error.
sending a form from a page to greybox. Currently the script doesnt seem to be sending the form. With the current code, the greybox pops-up for a second with no content then disappears. Here are my scripts:

I have ajax request with a success function. The data I'm getting back are an entire <html> ..</html> page. Is there a way to retrieve from those data only a given DOM element by its id ?

I want to get the solution for a null xml response at the moment if there is no error i made a work around so the xml returns a fullstop which shows up as an error but in white. I would like to know if there is a way to keep the elementByiD as null when the xml is null as it was returning the error object required is there a better way of doing this????

I spent the best part of yesterday trying to get my form to be sent to the server however for the life of me I cannot figure out the problem. I haven't used prototype before but here is my code that I think should work perfectly fine,The php script works perfectly, i've entered test data into it and it makes a connection to the third party server using curl and then requests information that I get back i.e. the routing id comes back. But I cannot test the data using the form as the request isn't working for some reason.
View 3 Replies View RelatedI have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?

Here is my ajax call:
Let me preface this by saying that I have ZERO experience with Ajax, and have simply copied this code from a blog elsewhere. What is shown below ties to a php file that I developed for a search function on our site. As the user enters their search term(s) in the text input field, the div below is populated with potential results through AJAX. I get all that.
However, I'd like to extend this a bit more. I'd like to enable to user to click the Enter key to follow the URL of the top search result automatically, without having to move their mouse and click on it.
Since I'm using PHP to generate the actual URL, I'm sure I can just send this back as a variable via AJAX, but with my lack of understanding, I thought I'd poke around here for some assistance. Can someone show me how to tweak the code below to accomplish what I'm looking for?
Code:
<script type="text/javascript">
function showResult(str)
{
if (str=="")
[Code].....
I'm less concerned about getting the Enter key to perform the submit than I am about passing the URL variable back to the form via AJAX. I've seen lots of examples of getting the Enter key to behave this way, I just didn't want to muddy up the original code above.
How can I select all fieldsets in a form which does not contain a div with class "Action"?

I have come across a very interesting problem that seems to be impossible to solve. Basically a web application that I am working on relies on a JavaScript function called go to change the input named view to the page name and submit the form. This form's type is post, so no values are included in the actual URL string. There is also another input called action and it's value is view. This is to tell the application that the user would like to view a page. The problem is because of the variables being of method post, page refreshes and back and forwards return errors because the post variables view and action aren't sent with the required data. To somewhat solve this problem I have created a feature that tells the application that if the post value page is empty then to try and get a GET var called page. To insert this var into the go javascript function I simple add this code
document.go.action = document.go.action+"&page="+page;
This line basically adds &page=[page] to the action of the form. The problem is, this code doesn't work because action is also the name of a form element. Referencing document.go.action refers to the input element named action and not to the form's action. Changing the named of the action input value is out of the question (Way to much changing of code, and possible room for error). What can I do to change the action of the form without referencing the input named action. Here is my go form and the JavaScript code:
<form name="go" action"index.php?sid=123" method="post">
<input type="hidden" name="action" value="view" />
<input type="hidden" name="view" value="" />
</form>

I have a very weired problem (which is not easy to describe.. but I'll do my best):I have a html page with several forms , only one of the got the action="ComputeAndReturn" and the other forms got only name="" tag.the problem is that after i submit the form with the action , and than after a computatioon it returns to the original page, now... if i will submit any of the forms without the action=.they will act as if they were defined action="ComputeAndReturn" (altho they are not!)if they were defined from the first time with action="anything", and than i would submit the form with action="ComputeAndReturn" this problem would not appear (the other forms will keep their action="anything" and would not "imitate" the action= "Compute AndReturn" to them selfs...
any ideas how can i keep my forms without action="" , cause all i need them to do is be submitted to pass the submitted value to other form inside that page.[code]
I am an avid php developer and i am starting to get into ajax so i can keep file sizes and code down to a minimum.
I am looking in the w3schools ajax examples but i am a little lost at how to send through a variable to the page i am using to process.
What i would like to do is send through an id that is being recalled from the database to tell it what to save over.

Having a few problems with a form validation script. Its supposed to stop sending the form if key fields are missing, but it just sends them anyway!
Below is the code i use in the header to check for blank fields:

From what i can see the fields match, it all links up correctly but still it will allow blank forms to be sent.
My server has an xml configuration file which I want to receive to my browser. I can do HTTPrequset directly to the file config.xml and get it in the responseXML, but I want to do it im more secure way, so the post request will be to some script ("python" in my case), which will open and read the file.
If my xml file looks like this:
What shoud be the content of the response?
I'm having a weird problem, not sure if I'm overlooking something or leaving something out. I'm trying to send values of a form to through AJAX to a php script then return a value. It works fine, except the author field is always blank. I've created a simplified version and it still works weird.
This is the javascript used to get the values and send them, when they come back the alert message shows Name as blank. I've looked in the PHP file to see if I made a mistake but I don't see anything.
function postComment() {
var author = document.getElementById("author").value;
var email = document.getElementById("email").value;
var comment = document.getElementById("comment").value;
var url = "includes/testComment.php";
request.open("POST", url, true);
request.onreadystatechange = showResult;
request.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
request.send("author="+escape(author)+"&email="+escape(email)+"&comment="+escape(comment));}
function showResult() {
if(request.readyState == 4) {
var message = request.responseText;
alert(message);
}
}
HTML Code:
<form>Name:<br />
<input type="text" id="author" name="poster" size="25" /><br />
Email:<br />
<input type="text" id="email" name="email" size="25" /><br />
Comment:<br />
<textarea cols="36" rows="7" id="comment" name="comment"></textarea>
<input type="button" onclick="postComment();" name="submit" value="Comment" /></form>
PHP Code:
$author = trim($_REQUEST['author']);
$email = trim($_REQUEST['email']);
$comment = trim($_REQUEST['comment']);
$response = "Name = ".$author." email = ".$email." comment = ".$comment;
echo $response;
Some servers return JavaScript as the response to an AJAX request. When
the response JavaScript is eval'ed it calls other JavaScript functions
already in the browser to update elements, etc. This seems like a good
system because it allows so much freedom in creating the desired
behavior in the browser. The required data doesn't have to be converted
to XML or JSON on the server. The browser doesn't have to have
templates for interpreting and converting this data into some change in
the browser. All of the conversion algorithms don't have to be written
and changed when new behavior is required. This remote procedure call
approach is the predominant system in the Ruby on Rails world.
(Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call
approach is a bad idea. I can't see why it is so bad because it is so
lightweight and flexible. It also helps to keep the client less
intellegent which seems good in a world of incompatible client-side
bugs.
If I use some neutral data format like XML to accomdate different types
of clients then I have to write different client-side interpreters for
each type of client (browser, RSS, POP, cell phone, etc). Why not just
write different server-side code that generates the correct JavaScript
(or other) for the requesting client type?
When is the RPC approach such a bad idea?
I am using ajax / php where I am looking up some info from the
database and populating a select list dynamically, however I am
running into some sort of size limitation with the ajax.response
object. If the string I am passing to javascript from php is too large
javascript does not get it all the data. The magic number appears to
be 6123 characters, anything below that it works fine, anything above
and if I alert the ajax.response, I see the string is cutoff. Any
ideas where this limitation is defined?
I am using following code
Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:
Code:
var myObj = eval ( xmlhttp.responseText );
I'm trying to send two arrays to an asp.net mvc method using ajax. The two arrays come from the values of two lists of checkboxes.The problem I'm having is that I don't know how to send them both at the same time. Here is my code at the moment:$

The asp function needs some way to differentiate the two arrays.
I am doing xmlhttp ajax stuff. I am using a script called "SEXYALERTBOX". I am using it to allow the user to input a password. The textbox is called BoxPromptInput. I do not think its inside a <form> tag.
Here is the code:
function askForPass() {
Sexy.prompt('Please type the password in order to see the pictures/videos','' ,{ onComplete:
function(returnvalue) {
if(returnvalue) {
var xmlhttp = false;
var pageResponse = null;
try{xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");}
catch (error){try {xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");} catch (error) {xmlhttp = false;}} .....
Any way to pass the value since I am sure the request.form would not work in this case since its not in a form.
I'm trying to work a way out on how to send multiple params via post using ajax. but the amount of params can change everytime, i know how to create the param string but how would the post page handle the different amount of them, is there a way to loop and recieve each of the params that get sent?
