JQuery :: Form Data Not Displaying In Textarea On Subsequent Return Of Data From A Call?
Oct 5, 2011
Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.
The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:
$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){

I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:

I'm having a little problem with a jQuery/JS script I just wrote in IE7/8. The problem is the first 2 lines of the returned data are not being displayed (w or wo styling) but only in IE. The strange thing is though if I alert the returned data it's there.
The code can be found at [url]

I stumbled on this problem while testing StatusNet for our next release; we use jquery.form's .ajaxForm() to do various AJAX form submissions, including the primary message-sending form which includes a file upload control.
We've not seen problems before, but since upgrading from an old Form plugin version 2.17 to 2.49 a couple months ago, I've noticed our development branch no longer works properly in Opera: the actual submission goes fine, but we're unable to access the XML return data (which usually contains HTML fragments to put back into the UI).
I have a test case which demonstrates this at [URL] (source of the main page & submit handler are included there), using current jQuery 1.4.4 and jquery.form 2.52.
Under Firefox 4.0b10 and other browsers, the forms submit correctly, and we can read nodes and text out of the returned XML just fine.
But on Opera 11.00 and 10.63, the submission goes through but we get back an HTML document containing only "<head></head><body></body>". On Opera 9.63, it also includes the text "Blank page."
I tried to trace this down in jquery.form's history, and the trouble seems to have started around 2.39 with a commit ironically titled "iframe load fix (mostly for Opera)", which changes the event handling for forms submitted via iframe: from that version on, a 'load' event handler is added directly as an onload attribute on the iframe's source, whereas previously it was added with attachEvent or addEventListener.
It looks to me like the iframe is throwing a load event for the "about:blank" page, instead of for the submission.
I can revert back to 2.17 or another working version for now, but I'd like to make sure this is fixed upstream;

The server i'm trying to post data to in an ajax call expects data in xml format, including a particular attribute value. I have to use Chrome browser which does not support the XML Class (e4x).
I tried to marshal my data as follows:
But the ajax call does not appear to transfer the xml data to the server even though the xmlhttprequest call appears ok in Chrome's developer tool console.
I'm wondering whether I'm forming the xml formatted data correctly.

I'm writing a web page, which should interact with pages on another server using an iFrame. I want to use a form on the parent page to post to the URL on the iFrame and capture the response, without reloading the parent page.
Here are the details:I have a FORM on the parent JSP page, with some session data in hidden fields. The point to note is that the whole session data is on the client side, in encrypted form. This data should be posted to the server for each request, synchronous or asynchronous.Now, I need to call an application on a server on a different domain. For this purpose, I am using an iFrame. The session data in the parent page should also be passed to the application in the iFrame.

I have a form which goes to my insert page which inserts the data into the table. Except I didn't want to do a redirect to another page so I thought I would do an Ajax call. Both pages work until I change it to an ajax call.
I am pretty certain that it is because I took out the <form action="insert.php"> because otherwise the page would redirect but if that is the case I don't know my way around it and if it isn't the problem I'm not sure what is.
But here is my code:

Someone on this site made a form for me that hides and displays fields, depending on which variable is chosen from a given array. They did a very good job with it with one exception. It seems the code that is used to hide certain fields also hides the form data rather than posting it when the form is submitted.
Here is the code for both the java (listed first) and the form itself.
// Funtion
// Description: show or hide element in the form according to selected element
//
function show_hide(){
if (!document.getElementById) return false;

I'm a complete newbie to JSON and I'm trying to make some sense out of itI think that what I want to achieve is fairly basic, but I have no clue where to begin. Here's my problem:I want to get the information from this JSON-string, fetch the value for realm_rank and display it within a header-tag in my html-code.

I have a form that asynchronously submits to a PHP file. The PHP file returns the following:
PHP Code:
echo�json_encode($array);
In my Console, I see the following:
Response:
{"groupname":"XYZ Group","id":4}
How do I display that JSON code through jQuery code?
Here's the jQuery code I have so far:
Code:
$.post("addgroup.php", { groupname:f.groupname },
function(data){
$("#groups tr:last")
.clone(true)
.insertAfter("#groups tr:last")
.html("<td class='tbldata'>"+ /* Returned JSON data (groupname) */ +"</td><td class='tbldata'> /* Returned JSON data (id) */ </td>");

I found this post: [URL] It explains exactly what I want to do. The person who had the problem seemed to have sorted it out but as my knowledge is not to great I am not to sure what he is getting at. I tried various things but to no avail. All I want to do is return data to a calling javascript using type get and datatype jsonp. If I simply Response.Write "[(""id"": ""123""}]" then nothing happens. So whatever the thread I revered to above is doing it seems to be going in the right direction.

I have my code php like that:
<?php
//Get the data from system and return in EU format
function ShowDate() {
$Date = date("d"."/"."m"."/"."Y");
return $Date;
}
//Get the time from system
function ShowTime() {
$Time = date("H".":"."i");
return $Time;
}
?>
Now I have two input box
<html>
<head>
</head>
<body>
Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10">
<br>
Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5">
<br>
London: Friday May 21 2010 05:12:00 <br>
New York: Friday May 21 2010 00:12:00<br>
Hong Kong: Friday May 21 2010 12:12:00<br>
Tokyo: Friday May 21 2010 13:12:00<br>
</body>
</html>
So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.

So I'm currently working on a ASP.NET Webforms site and I've run in to a small problem. On my .cs file I have the following Webmethod
[WebMethod]
public static string IsJobEditable(int jobid){
try{
string isEditable = "false";
JobsBLL jbl = new JobsBLL();
int jobStatusId = jbl.GetJobStatusId(jobid);
//If the jobs is either waiting or being edited it is
okay to edit it
if(jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Waiting) || jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Edit)){
isEditable = "true";
}return isEditable;
}catch (Exception ex){
throw ex;
}}
This function in this case will ALWAYS return TRUE as a string. On Aspx page I have the following
$(function () {
$.ajax({
type: "POST",
url: "Coordination.aspx/IsJobEditable",
data: "{jobid:" + jobid + "}",
contentType: "application/json; charset=utf-8",
dataType: "text",
success: function (result) {
alert(result);
//This is written out in the alert {"d":"true"}
I want this in a variable as a string so I can do a check on it before I do some other actions. The format is not a String so I cannot split on it to retrieve the "true" part.
},
error: function (err, result) { alert(err); }
});});
As you can see in the comments the value I get back in the Callback method is in to me a weird format. The type is unknown and I need this value to be able to proceed with my entire method surrounding the small portion of the Javascript. Where to access the result variable / data as a var or anything else that will let me put it into a var (as a string).

What i want to do is: as soon as a txt box (name of txt box is 17) is populated with a date, I want to automatically display the Gregorian version of that date in GrDate2 text box.
Here is the site (you can check out the source code there). [url]
The GrDate2 txtbox displays nothing. I have checked with Jquery experts and the jquery code is correct and should work. The only thing I can think of is it has to do with Javascript or Html.

Read the first reply below first/instead, it's probably more helpful than this one
There's a lot of talk about AJAX these days and it seems to me it's turning into a hammer for a lot of problems that aren't really nails. If you want your pages to call home but don't want to have to deal with XML parsing and extremely spotty browser support, here's a very simple way to effect communication from Javascript to the server. The server can only (easily) communicate back on the next page hit with this method, but as a one way conduit from client to server post page rendering it can hardly be beat.
I've set it up with a really simple case that keeps track of the total time each user spends looking at a page in ten second increments. I have, for clarity (I hope) stuck it all in one PHP file, but it'll work the same with any server side language:
<?php
// this block isn't really too well coded or useful, it's intended more as a simple proof of concept
if (isset($_GET['ip']) && ip2long($_GET['ip']) !== false)
{
// if there's a GET variable (this.php?ip=something) and it appears to be a valid ip...
$fname = sha1($_GET['ip']) . '.time'
if (file_exists($fname) && strpos(($pre = file_get_contents($fname)), '='))
{
// if we have a file and it looks like it might be in the right format, increment the value contained therein
list($ip, $time) = explode('=', $pre);
file_put_contents($fname, $ip . '=' . ($time + 10));
}
else
{
// else just write it in and hope for the best
file_put_contents($fname, $_GET['ip'] . '=10');
}
/*
//actually returning an image here can help get the loading message out of browser's status bars
header('Content-type: image/gif');
fpassthru('small.gif');
*/
}
else
{
?>
<html>
<body onload="javascript:setTimeout('serverTick();', 10000);">
<script language="javascript">
var ip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>' // give the javascript an ip or a hash or something to pass back that will be reasonably unique
function serverTick()
{
setTimeout('serverTick();', 10000); // call this function again in 10 seconds
var notshown = new Image();
notshown.src = '<?php echo $_SERVER['PHP_SELF']; ?>?ip=' + ip; // calls this file in attempt to preload an image, instead triggering the above block of PHP
}
</script>
</body>
</html>
<?php
}
?>
This will work in far more browsers than AJAX will, and it's not subject to any domain restriction, it can post to another server without generating security exceptions. It may be possible to get data back in the body of the image and it's definitely possible to get data back coded as image dimensions, if you want to push this method a little further.
