[Code]...
I have a jquery dialog with a registration form in it. My problem is: I want to check if the username (input) already exists in the database, if so I want to return a error.
I know I have to use AJAX... but how?
Explanation of my form:
(this is a dialog)
My form:
Username: testuser ERROR: username already exists
Password:
Name:
[Code]....
I've got this form that needs to check if the user input is already in the database, if this isn't the case it should disable the submit button and display an error depending on which input isn't found.
eg. client name isn't found...
This is the form:
How do I get this to work?
I am trying to write a script that will search the page for a certain ID...if said ID exists, then I want to hide a few other IDs.[code]

Let me explain the issue which I'm facing with an example.My URL is http://localhost/~gaurav/dstreetmantra/register.php.One of the anchor tags in my navigation bar is <a href="register.php">Register</a>.The code needs to be able to check whether the value in this very anchor tag's href attribute is present in the URL.If it is present, the word 'Register' register would be highlighted. If not, some other link would be highlighted.As I said, I'm doing this for the navigation bar. This way, it'll check which of the links' 'href' value is present in the URL, and thus highlight that link.I'm assuming this can be done using Regex, but I do not know how to use it.
View 4 Replies View RelatedI'm using a version of the tab system shown here: URL... and I was wondering how I would go about a couple of things...
1) When the tab loads, bring it to the foreground
2) If someone enters a tab title that already exists, then load that tab rather than creating a new one.
This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.

jQuery.css(e, "background-color");jQuery.css(e, "background-color");
Not works on a elementl like:

But will work with..
<div id="directions" class="rounded-big">

I'm working on something that I want a user to be able to override by including a specific class somewhere in the CSS definitions. If that class doesn't exist I want to add a default style. This seems like something that should have come up before but search isn't coming up with anything. Can someone point me in the right direction? Local styles/classes override global classes right?[code]...
View 24 Replies View RelatedI've knocked together a simple chatroom app that gets new messages via an ajax call and prepends it to the list of messages. It does this by looking for the first hidden div with ID comment_counter, which contains the ID of the most recent message in the list that the client already has. The ajax call then makes a request to another page that returns a string of HTML with just the messages with an ID greater than the most recent one. That gets prepended to the current list of messages, the interval repeats, and so on.
The function looks like this:
setInterval(function()
{
var messageID = $("#comment_counter").first().html();
$.get("page.php", { m: messageID, b: <?=($post_id)?>, n: 'true' },

I haven't done any jQuery development prior to this, and it's been a while since a I did any web development anyway
I have the following:
I need to apply "margin-top: 5px;" to the img within the second <p> only if there is a preceding <p>.
In my last row (parent Table) with colspan(tr), I have another Table (without any.attributes) which was generated by GridView, Paging enabled and located in footer ..
How do I know if that Table exists in my last row(parent Table).. this code won't work ..
$(".DdsConstant").each(function (index, element) {
var text = $(element).html();
$(element).html(text + ":"); });
The above code works for me, but I want to be able to skip the elements that already have a colon or question markin it.Example: Search Name: or Perform this daily? should be skipped. But Search Name should be changed to Search Name:. I will put question marks in manually. I have tried a few things and done some searches but no luck.

View 1 Replies View RelatedUsing Javascript I need to figure out how to check if a URL actually exists. The problem is that the Javascript file may not always be there so I have I have to check every time I need it.
AJAX is not an option AND its has to cross browser compatible.
*NOTE The URL will always be pointing to a Javascript File

I'm trying the figure out how to check if a id exists.
I have tried this;
if(document.getElementById("theID")
Then do this
But that doesn't seem to work.
All I want to do is if it doesn't exist then don't run the function.
I have protected my cookies by setting them to httponly, but now I am trying to check them through jQuery without sending a AJAX request that checks if the cookie exists using PHP then returns the confirmation (slower). So is there a way to read my own cookies only using jQuery?
View 1 Replies View RelatedI have the following script that auto-submits a form at intervals.
setTimeout("document.forms['pageReloader'].submit();",90000);
Unfortunately, sometimes the target webpage is not available and I get
"page not found". That immediately kills my application, until I manually
restart it.
Is there a way in javascript to first check if a link exists before the
form is submitted?
For php programmers, an example of what I want will be:
if(fopen("http://www.example.com/", "r") {

How can I check if a function exists in any of the scripts on my page?
I prefer if it can work for both Javascript & VBScript.
How do I check if an object exists in Javascript?
EG:
if (document.getElementById("product").value == null)
{
prodValue = "";
}
else
{
prodValue = document.getElementById("product").value;

This gives me an 'object required' error...
I'm using ccs3PIE with my site. What I want to do is check if a DOM element has a css property like border-radius and then add a class to it.
The problem I'm having is that I don't know how to check for the css property. I've been searching for it for a couple of hours now and I can't find anything that seems to work.
I found out how you can check if an array value exists but I can't seem to get it to work with the options array for some reason.
how I can find out if a certain select value exists?
I'm not entirely sure this is possible. I hope it is, and it doesn't seem to far-fetched or impossible.
With JS, how would one go about checking if a user has DivX Web Player installed?
Usually people put in code within the embed, so if it the player doesn't load, it would have the message behind stating the fact. However I haven't seen this used at all with DivX, instead, you see pop-up boxes, whether installed or not, stating "Don't have DivX Web Player? Get it here for windows or mac"
I find this extremely annoying, and would never want such informalities on my website.
If I have a form like so:
<form>
<input type="text" />
</form>
