Simple enough. This beautiful plugin is what I"m using:[URL]..The problem is, it has no documentation on how to detect a post failure. I know these are rare, but I'd like to code defensively.
View 6 Replies[URL] I'd also like to use this plugin, so I don't have to create complex validation rules. validation plugin [URL]Trouble is, I can't figure out how to prevent form submission without first checking to see if the form is valid. My attempts so far have been based on using submit() to prevent submission of the form if validations valid() method returns false. But this doesn't seem to work. If I use ajaxForm, the submit() function seems to work differently. A form will still be submitted, despite a return false. validate has a valid() method that returns false if the form fails validation. How can I submit the form only if valid doesn't return false?

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;
From the little I've read in this plugin's source code, ajaxSubmit() switches to "iframe mode" whenever it detects a file link in the form. The file is uploaded fine, but the server, which normally replies with different content. based on HTTP_X_REQUESTED_WITH header, fails to do its thing. This header is normally set to "XMLHttpRequest" on normal jQuery .ajax() calls.
The server I'm running is on rails, and I'm using the "request.xhr?" test.
I admit I'm not too familiar with iframes (or jQuery, for that matter:), but surely there must be a way to get around this, so that this can act as a simple drop-in replacement. Should I be looking at other headers, like "Accepts" or the kind, or should the plugin (or my code) be forcing the HTTP_X_REQUESTED_WITH header?
How do you find out if a certain Plugin has been installed in IE 5.5 using Javascript?
I know that in netscape you can use navigator.plugins so I was hoping there was something as easy as this.
I'm showing a form in a Simplemodal dialog in combination with ajaxForm() to redirect the resulting page to another DOM element. The success function of ajaxForm() closes the modal dialog.The resulting page in the other DOM element has no access to the jquery function $(). When I load a page using ajax into the DOM element there is no issue access the jquery function, this only happens when I redirect the resulting page from the ajaxForm() function.

I'm going to make an attempt at coding a nice tree menu that is decent with browser support.
I want the tree to be displayed on all browsers (well, within a decent range). Of course, on older browsers, the menu won't be as functional.
Now, I'm going to be combining the javascript with a server-side language (asp.NET) and I'll be able to do some basic browser detection on the server.
But, I read about javascript object detection and am wondering how well that works exactly.
Like, what if a browser that doesn't support objects period tries to run some object detection code? Also, which browsers support user defined objects?
See, I'm thinking of breaking down the script in 3 categories. Browsers that won't get any javascript... these would be the browsers that don't support object detection, browsers with basic javascript... with these I would be able to code my own object and I would test for different features. And then there would be the browsers that can run it all.
So, basically, my question is what browsers support what features and how should I break down my code between them? A long time ago (back in the Netscape 4 / IE4 days) I did some javascripting, but since then I haven't really done any. I remember that NS4 didn't support div tags but supported layers... anyway, it got really messy.
Variables are reaching the php but callback isn't firing. Multiple forms on the page - I've stripped out everything extraneous to try and get a callback. (strangely Firefox 3.0.10 hits the php but breaks while running Firebug(?) and doesn't seem to work in Safari 3.1.2) Sorry if this is covered but been searching and can't solve. php included in case I'm doing something wrong there (as well?) javascript always breaks when I get my hands on it

First, I have to say the jquery form is just perfect and fills very well a common issue for those who need to work with ajax. I would like to know, or even sugest a new feature if it is the case: how can we get, on client side and after an 'ajaxSubmit' call, the error code produced on server side? Is it possible to include such function on jquery form? Because we already have a 'success' callback functionality, how about a 'failure' one?

I'm having a problem with same origin policy protection using JQuery 1.4.4 and the jquery.form.js AJAX plug-in. I have an AJAX contact form which works fine so long as visitors preface URL's they type in with "www". But if they navigate directly to a URL on my site (not using www), the URL resolves OK but the URL doesn't match what I use in my AJAX form. In Chrome, this results in a console error:

I am returning the following to $getJSON() and not getting any results:
{"QC":["x","y","z"],"RM":[{"DEFAULT":"default_project1"},{"DEFAULT2":"default_project2"},{"DEFAULT":"default_project3"}]}
In the "RM" array there are three objects, each a single name/value pair. The name of the array[0] object ("DEFAULT") is identical to the name of the array[2] object. No results are returned by the getJSON call. Since each object is a separate array value, there shouldn't be any object name collision problems. Note that if I change the name of the array[2] object to "DEFAULT3", the data structure is handled properly.
I'm trying to figure out how to integrate jQuery Validation plugin with the qTip plugin [0] to show custom error message displays. I've
had partial success with the following code:
$("#RegistrationForm").validate(
{
errorElement: "span",[code]....
At this point, that successfully displays the validation failure message in a qTip tooltip when it occurs, but there are two problems
with it:
1) The error tooltip toggles between visible and invisible onmouseover and onmouseout. I'm sure this isn't really an issue with the Validation plugin, but rather something I need to figure out with the tooltip plugin. But, my bigger problem is...
2) Even when the invalid condition is fixed (valid data is later entered into the field), the error tooltip remains attached to the field that was previously invalid, even after the field is valid, and continues to toggle between visible and invisible onmouseover and
onmouseout. I'm fairly certain that this is because I've not yet destroyed the tooltip object, but, I can't seem to figure out a way to intercept the "valid" or "success" event with a reference to the element so that I *can* destroy the attached tooltip object.any experience with combining qTip with Validation, or, if I'm missing something in the docs (I've not been able to find anything like this yet) about how to handle/override event handlers for individual form element invalidation/success. I *did* try attaching a function to the "success" attribute of the validate function, but that seems to only give me a reference to the success label, and not the element that its attached to.
I am trying to get an alert box with line breaks in it. I want to display a couple pieces of information, and want them broken up. I tried using to get a new line, but kept getting errors in my code.
alert("The combination you have selected: " + + "Background Color: " + color1 + + "Text Color: " + color2)
Of course color1 and color2 have been declared and defined, so I know there isn't an error there.
In prototype with ajax.updater you can chose to show errors in another div than the one you want "real" content in.
Code:
new Ajax.Updater({ success: 'items', failure: 'notice' }, 'ajax_req.php', {
parameters: { text: $F('text') },
insertion: Insertion.Bottom
});
But all information i print out from ajax_req.php gets in the items div. How can i print out errors from ajax_req.php into the notice div?
My original idea of two trains, however pictural it was, appeared to be
wrong. The truth seems to be even more chaotic.
IE implements its standard down-up model: any mouse event goes from the
deepest visible element to the top. By carefully studying fromElement
and toElement properties, one can handle events on any point of their
way up.
NN/FF implements a "Russian hills" style: mouse events go first
up->down (window->deepest element), and right away after that it goes
down->up (deepest element->window). On theory you can handle events
during any phase on any level. On practice this implementation has some
major flaws. I don't have NN handy right now, but in FF we have:
I am trying to figure out a way to have a page redirect if the mysql connection fails. The issue is that the page is already loaded and the only time this would be needed is if the user tries to perform operations on a loaded page after the session runs out.
So basically, I have a page that will allow you to search for an item using ajax, then select an item and press add which will place the item in another table displaying detailed information. Both operations connect to the database using SESSION variables to save the connection information.
My goal is to use the "or die()" method to print something that will force a redirect because this could happen in a number of places in the site and I want to try and get them all in one swipe.
Here is what seemed like it would be the most promising:
$conn = mysql_connect($_SESSION['host'], $_SESSION['username'], $_SESSION['password']) or die("<script>location.href= '../login.php'</script>");
Unfortunately the javascript never runs.... I tried putting alerts also and nothing, but with firebug I can see they are printed.
how I can ensure that the javascript is executed?
The first div in this example has the position property stated in the div itself.
The second has it stated in a separate style statement, and it doesn't get inherited, though another property from the same style statement DOES.
Firebug makes no complaints.

I'm testing a web site in a local directory by opening index.html from the File/Open File... menu of Firefox. When I use xHttpRequest.send() to retrieve a file to include in my page, the callback's status argument is 8 and req.status is 0. I suppose that the 8 is correct in that the req.status isn't 200 but it seems that for file:// (as opposed to http://) that req.status == 0 might be treated as success. I haven't tested far enough yet to know what req.status would be if the file I tried to retrieve was missing.
