JQuery :: Format Returning Message Of Php-ajax-php In Jqm?
Dec 22, 2011
i happen to chase my fortunes in development as a newcomer. Scenario,// using jqm-rc2, sample registration - ajax callback scenario
1. Say formtoregister.phpcalls a studentsregister.php // Ajax/json and POST
2. Thisstudentsregister.phpdoes this 2.1 validates POST data, does db work and 2.2 sends back to formtoregister.php following messages //on success echo json_encode($promoinfo);// json format, see below the echoed content echo "<p>Welcome $user </p>" problem,is plain format text is printed Message is: {promo code: JsonNAjax}<p>Welcome Beginner </p>
This plugin enforces max length on text areas and reports back the number of characters left to use.How would I add commas to the feedback message that says how many characters are left?
Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!
What may be relevant: - site uses mod_rewrite for friendly url's
In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.
What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)
Is Json considered the better file format for loadind data via Jquery AJAX? I am going to use it either way, but from a cutting edge stand point, is JSON looked at a more cutting edge since it loads faster. 2. And for that matter is anyone using css3 and E4X? All these seem to require the latest versions of all browsers. Since my goal is to be cutting edge I was thinking to do some stuff in the above listed that require only the latest browser if it is detected, if not use what works in most all browsers? What are cutting edge web app developers really doing at this time?
if it's possible to return an array from my php generated content to ajax's responseText. I tried echoing back the whole array variable but can't seem to fully receive it in javascript.
I'm attempting to simplify my javascript code when it comes to ajax, but afterwords it only prints 'undefined' to the screen rather than what I want it to print.
I want to be able to put something like this on my main page onclick="document.getElementById('output').innerHTML = print_output();" where print_output() is the ajax function. This way I don't have to use a function to assign values directly to innerHTML and I don't have to muck about with a js file whenever I want to change my page layout.
To do this, I created a recursive function:
function print_output(return_value) {
if a value has been passed to the function, simply return it if(return_value || return_value == 0) { return return_value; }
[Code].....
but like I said, it prints 'undefined' out to the screen. Why isn't this printing the contents that it receives from 'index.php' like it's supposed to?
I'm having trouble placing some data returned by an ajax function in the page where I want it.
I've included the relevant html and the javascript function below. There is some php code included which works but is not relevant to this question. The first ajax part of the function works. I have tested it with positive results in another context.
The part starting with "var x . . ." is the part that is not working. This part is supposed to generate the following html: Code:
Iam using JQuery DatePicker Plugin , created by Kelvin Luck [url]. Plugins default format is d/m/Y. how to change its default format to US Date format (m/d/Y).
I am running the scripts below which should return a string containing a URL.So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.
I can not for the life of me get an ajax example/tutorial to work. I have tried dozens including prototype library and JQuery.
Here is my latest attempt:
As you can see I am trying to alert the variable teamH but I keep getting an undefined in the alert. I also tried a static drop down and I received the same undefined alert.
How I get that variable to contain my drop down choice?
I'm making a script that requires cross-domain scripting to get the statuscode of other files. I'm currently using a small PHP script to relay the files from the remote server onto mine. If I want to get the files directly using AJAX, it is not allowed for obvious reasons. I don't want the actual files, I only want to get the status code of that file, and it is going to be either a 404 or a 301. I would've assumed that as the AJAX call is never attempted, the statusCode will be 0, and this is what the actual call variable returns.
However, in Firebug it shows the statuscode next to the request (404 or 301), even if, the call has never been made. Why is the statuscode appearing in Firebug but not in the statuscode variable?
I'm trying to prevent duplicate entires in my DB for a newsletter submissions form. I'm successfully preventing the duplicate entries, but I haven't been able to revise my jQuery to print the error.I've included the PHP just incase I'm missing something there..
I have a web application that has a few div tags in the base index.html and calls a java app for the output to the div tags. All is working ok, except when I try to format a ms-excel document as output from the java (to the div tag). If I invoke the java app directly in a web browser, the excel popup window comes up and my output goes to an excel document. However, if I invoke the java app (using Ajax request/response) I get the output to the div tag and the excel popup does not come up. Is this something special/different I need to do when using a div tag/Ajax?
I would like to get get some data which format is "XML" and it is returned from an API. However, the $.ajax() doesn't work in this case? But the same code works when the "XML format" data is from an XML file. Can anyone tell me why?
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
I have a bunch of divs with the same classname, 'mediafield':
And I have this jquery code in my header:
So I know that the click function is getting implemented.. The alert box appears however I get the following error in firebug: uncaught exception: Syntax error, unrecognized expression:[@class=mediafield] Line 0
Nothing happens when firebug is turned off... So I'm not sure why it's throwing the error.
I'm working on a small project and want to create a simple dialog window. I know I can use a plug-in, however that is a bit of a over kill plus its a good way to learn more about jquery.
So everything was going well until clicking the button. I cannot find a way to return the value of what button was pressed so I can take further action within the function.
I have the hover event set up. There are 100 elements in my document of the class square. What I want to do is return the ID of the current square that is hovered and edit the style=' ' attribute of the .square with that specific ID.
Basically what I'm trying to do is write a plug in which connects to a sharepoint web service, traverse the results of the xml document that is returned by the web service for certain elements, and then return a collection of xml elements which I can use in another function on the page that is calling the plugin.My code looks like this:Main Page
<script type="text/javascript"> $(document).ready(function() { var listItems = $.sharepoint();
