Ajax :: Updater Implementation Does Not Work / Fix It?
Oct 12, 2009
I wanna make a live-error-checking sign up form.
So these are the codes
this is the php file which return echos to the js files (there's no error here, I've posted this so you know what it's all about) [code]...
if a user writes in the text box for nickname a nickname that is already registred then in a text box near the input text it will appear something like : "This Login name is already taken!"
and so on for every field (firstname, lastname...)
I have done this previously with classic ajax tehnics (that with onreadystatechanged) and it worked. But this version does not. Can you spot the error here?
I have a problem which I am not able to solve. I read a lot and tried many things but without being successful. Mhh.. The problem I struggle with is a simple .toggle() of a DIV. This is working fine. But now I do an ajax request and get the response back from my javascript ajax implementation (I'm using ajax anywhere). Within this implementation I work inside a callback routine which makes it possible accessing the response before updateing the DOM. Inside this routine I want to .toggle() but this is not working. It happens just nothing. I also do not get any javascript errors. As soon as the request is completly done I am able to .toggle() again.
When I am accessing the DIV by using jquery ($('#div_id')) it is referenced to the correct object within de document. Only the .toggle() does not work. .hide() for example is working fine.
Background: I am doing this like this, because I want to know if the response contains validation erros. If so I leave the DIV with the form inside as it is an highlight the error. Otherwise (no errors) I close the div with .toggle(), update the dom with the new form and open the DIV again.
Many reports are facing a problem that they lose the jquery binding. But this is not my problem as far as I understand.
In my php script (which is located at URL 'ships'), I am just getting the value of 'variable' from the $_GET super global but I obviously want that value to be dynamic and equal to the value selected in the dropdown.
So the missing piece is passing the selected dropdown value from HTML / Javascript to PHP. Anyone know how to do that?
Did anyone implement or can direct me to an implementation of virtual mode (render only visible rows, but still have the scroll work right) or something similar in the AJAX Sys.Preview.UI.Data.ListView?
I need to display a very large table (`1000 rows) and it simply isn't feasible to render everything.
I'm grabbing an update from a json file, but I want to have it update perodically to the screen, overwriting what it found before... sort of like Prototype's Ajax Updater. Is this possible in Jquery? I scoured the groups to but only found a digg spy thing, which is sort of what I'm looking for but it was dated for 2007, so there's gotta be something new or is that it?
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?
This is my implementation of an n x m matrix in JS:
var n=parseInt(prompt("n:",1)); var m=parseInt(prompt("m:",1)); function array(){ this.length=m+1; for (var i=1;i<=m;i++) this[i]=0; } function matrix(){ this.length=n+1; for (var i=1;i<=n;i++) this[i]=new array; } var a = new matrix();
Is there a good linked list implementation in the public domain? Or that someone on this group has already written that they'd like to put in the public domain, right here on this newsgroup?
I have a request to implement iGoogle like UI features, specifically, the drag/drop module boxes, and configurable elements for each module box. Currently, I have existing module box with all the forms and elements (backend support for them too). But they are not drag and droppable, and not configurable.My questions are: 1. Do I need backend engineering involved in this implementation? my understanding is: it's pretty much front end UI work and backend already provided all the form elements, backend DB, etc. for this.But my only concern is: how can the system save the user's configuration when they login the next time? Do I need backend engineering's help for this? related DB setup, java class files, etc? 2. is there any jquery UI API/plugin I can take advantage of so that I don't have to do everything from scratch?
I'm looking for a Triple DES implementation in Javascript.
My requirement is that I need to encrypt data using Triple DES in Javascript and decrypt on server side using C#. I found a few, but I'm unable to decrypt the data in .Net.
Code: function showForm() { if (!document.implementation.hasFeature("Core", "3.0")) { alert("1");//[code].....
on FireFox 3 and only the alert marked with //go off. In IE 8 on the other hand all of them go off. These are features described in JavaScript for WebDevelopers 2nd edition.This cannot possibly mean that IE 8 is missing all these features...what is qrong then?!?!
've been looking to implement a function which allows me to populate 2 form fields from an onClick event. I needed to be able to fill/modify one field on a single click and the other on a shift-click. This is all working fine but only for IE 5.2/Safari/Opera 8.02 but fails in Camino(Gecko). I don't have much experience in working across the different DOMs, I do know that I will need to use a different variation of the shiftkey (e.shiftkey?) and for NS4 (e.modifiers?); but I really am not certain as how to handle these correctly. Initial testing has been with limited success.
Could anyone give me some practical pointers to handle the 'shiftkey' for Gecko/Netscape4? (Gecko is more critical)
Current code as below:
function fillform(txt) { if (event.shiftKey) {event.returnValue = false; alert('shift on'); MM_changeProp('fieldone','','value',txt,'INPUT/TEXT')} else {alert('click only'); MM_changeProp('fieldtwo','','value',txt,'INPUT/TEXT')} }
I have my code and it works of filtering data by Month and year.But it seems i got a problem when using accordion. For now, i created it manually but i want to make it automatically.If you click the dates in brown area it will display the news with that month. Can anyone help me out?I only have problem in accordion.[code]
I don't know enough about the technology yet to know whether this is a ridiculous question-- but is there no cross-browser javascript implementation of XMLHTTP and SOAP for use in calling web services?
It looks as though MSFT expects the client to be running Windows and ActiveX and have certain DLLs installed; and Mozilla seems to have its own implementation of SOAP. Is it possible to implement these protocols in pure client-side javascript?
i want to send a simple HTTP-Request to a JavaEE Backend with jQuery. In Chrome/Firefox it works just fine. In IE on the other hand, it does not. IE does not show any error in the console, nor does it show the request in the network tab. Nor does the request receive the backend. So, am i doing someting wrong here?
I am trying to use the regular .ajax functionality and it works great on most browsers but I noticed a phenomena: When I make an ajax request outside the "root" / index file it adds "/" to the end of the request which results in a 404 request... How can I eliminate this behavior and how does url really work in the ajax request ?
I've been build and application, using firefox as my testing browser. I come to find out that, when testing the web-application in an internet explorer browser, AJAX doesn't work.
I'm sure that "insert.php" works because I've tried the <form method="POST" target="insert.php"> And it adds to the database through "insert.php". But when I remove the 'method="POST" target="insert.php"' And replace it with $.ajax() it won't work.
Here's the code: $(document).ready(function(){ $("#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var message_wall = message_wall.replace(/</g, '<'); var message_wall = message_wall.replace(/>/g, '>'); var message_wall = message_wall.replace(/<.*?>/g, ''); var FeedUNum = $('#FeedUNum').attr('value'); var FeedConn = $('#FeedConn').attr('value'); $.ajax({ type: "POST", url: "insert.php", data: "FeedUnum="+FeedUNum+"&message_wall="+message_wall+"&FeedConn="+FeedConn, success: function(){ $("ul#wall").prepend('<li style="display: none;">'+message_wall+'</li>'); $("ul#wall li:first").fadeIn(); }}); return false; });});
