Basically i want to grab some data from the royal mail(UK) site, to use within a CMS, so the sales team can easily find the tracking info about a customers order.
Royal mail have recently allowed get requests which populates the track and trace form field and auto submits the page via a 302 redirect e.g.
royalmail.com/portal/rm/track?trackNumber=x
With X being the tracking number. Try: [URL]
(the links above should have www and http etc on but sitepoint won't allow to post them like this because of the spam filters)
So what i would like to do, if it is possible, is to use jquery to grab that page and possible grab a certain paragraph (in this case the first p of the class "track-right-box") so that the sales team don't have to go to the site every time they want to trace the order.
Now a figured i could use $.load or $.get in jquery to do this but firebug is throwing up the error: Access to restricted URI denied" code: "1012
Which i'm guessing is something to do with the security setting on firefox.
I've started working with the jQuery UI 1.8 Autcomplete recently with remote data. I was pleased with the ease of initial implementation, but before long I ran into a classic race condition.As I type, the search query gets more specific, so it takes less time for the server respond. As a consequence, it is possible for the old response to arrive after the most recent one. Obviously, this is producing undesirable effects.I'm a little frustrated that the plugin doesn't have a way to manage this. To me, it seems that it makes the "basic" remote data implementation unreliable in most real-world situations. It also seems as though this would be a common problem, but I've found very little literature on it.
I've found that autocomplete is a relatively new addtion to jQuery UI, so I've put the frustration aside and started my own widget which extends autocomplete to solve for three things: 1) race conditions; 2) animated open/close; 3) caching.The nature of this post is two-fold. Not only to share information I've gathered on the topic of race conditions with others who might be having the same trouble, but to (hopefully) gain some insight to how other people are solving for this.The first piece of this puzzle was that $.ajax() (and related methods) return an XMLHTTPRequest instance. As described at stackoverflow.com, this grants us the ability to use XMLHTTPRequest.abort() method. So I just keep a handle to the XMLHTTPRequest instance, and if it exists, call abort() before the next request is made.Using a firebug, I could see that the requests were being aborted as expected and the symptoms of the race-condition ceased. So far, so good... then I got to IE. Not so much.In IE, I was seeing run-time errors. The odd thing is that the run-time errors seemed to be coming from deep within jQuery UI, rather than my code yet commenting out the abort() avoided the run-times. After scratching my head for a while, I used the following simplified code to shed some light on the situation:[code]
In Firefox and Chrome, behavior is as expected - no alert box. However, in IE6 and IE8 (IE7 untested at this time), the success handler still fires! As it turns out, the run-time errors were because the response was undefined as it got passed through my success code path. My next thought was, "maybe I can just evaluate textStatus". Unfortunately, it turns out (as seen in the alert box) it contains the string "success".
I'd like to learn how data is passed form one file to another and then displaying at when an error occurs. I have this php script that checks if an domain really exist
Here is what I am trying to do. On my web page, I have three choices for the user to pick from. After the user selects one of the checkboxes and clicks a submit button, I need to send a http request to a remote server to record the user's choices (actually it is an https that I am sending),.. so I need to send something like this.

The remote server responds with an xml response that looks like this:
So, I want to post the request, read the response (answer) back from the other server and display it on my page. So, my dilemma is as follows:
1) my understanding is that I cannot do this with AJAX using an XMLHttp object because it is on a remote server and it would violate some sort of same-domain security. Is that correct? If in fact I can do it in AJAX, how do I read the response back from the other server?
2) if I am correct in my assumption in 1) then what is the best way to accomplish this task?
I am trying to use asp for remote validation instead of php. But it did not work. This is whatI tried. $(document).ready(function() { var validator = $("#Member_Form").validate({ rules: { Member_Name: { required: true, minlength: 2, remote: "users.asp" }, }, messages: { Member_Name: { required: "Enter a username", minlength: jQuery.format("Enter at least {0} characters"), remote: jQuery.format("{0} is already in use") }, }}); Also how is the member name passed to the asp page. I tried reading it as query string. But it did not work.
I am trying to read an XML file from a web source to display on my site. I can't get it to work ..GET seems to come up with an error - I tried crossDomain: true with no luck and have tried on a local and web server.
I have 3 tabs that call an external ASP page that has a rather intensive Database query and takes a while to execute and display. On my tab there's a link to another page. once that page is finished the user goes back to the tab. But my problem is it's going back to the database page (that takes a while to execute).Can the original page be cached and remembered so that I dont have to keep calling my database page?
I want to use jquery or js code to do the following work:
get the list of files of a folder (files are pictures) that the folder is in remote. and get the names of those pictures and store them in an array.. to create dynamically img element in page.
can javascript do that? without using of a backend language( web server)
I'm using jQuery $.ajax or $.getJSON on document.ready to access data from the server through coldfusion remote cfc files.
My url looks something like this for the main page [url]
When i go to a new page i.e. [url]
The ajax functions are called but are not collecting new data (only in IE). IE caches the response and wont give me a new one unless I refresh the page, which I don't want to do.
Here's an example of a function I call. I've also tried $.getJSON with no success.
function getGrains() {
I've looked into ways to make sure IE wont cache files. Some of the popular suggestions are:
Add a random parameter to the url: I've done this:
Change get requests to posts: Done (see function)
Also, jQuery's cache:false doesn't work.
I'm not sure I can use the meta tags or header cache-control functions because it's not caching my html page, it just caches these HTTPRequests from within my javascript file, and they're not loading html, just json objects.
i have one task in which i have to update the information on DIV on one of the webpage which will run on another system which can be any client system. is it possible to update the information of the web page in real time so that if some client is watching the other web page at that time, he will see the latest content.
i dont want to create server side scripting and logic for this as this is very small content. anyone with some idea about this?
Currently I was able to load remote JSON (php) file using JSONP protocol. However, how to do if my remote file is static? In the doc, it said: you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". But since my remote file is a static text file, how can I specify the callback in the output dynamically? In fact, I also wonder if it is possible to control the random callback name by modifying jquery source code...
I am attempting to read XML information from a remote source into a javascript array. Upon retrieveing the XML, I load it into array by sections. I am doing this with the following code:
I'm trying to load a remote URL (or rather just test to see if a remote page exists).
This works just fine:
But swap in a remote URL and I get nothing:
I don't actually need to load the remote URL, just determine if it's accessible (using it to test whether a user is connected to intranet or not). But I can't even seem to get to that.
I created a page a set of tabs, each tab loads an external page. The problem is that when I click on each tab, the external page contains script jquery and will not run.How I can do to upload the script to each page there is external?
I'm brand new to jQuery, and I am really interested in learning about it because of the potential it offers to enhance my webpages. To give you some background, I am self-taught in PHP and MySQL...not on a master's level, but I have designed and built database-driven sites with success and am confident that I can learn jQuery if only I could get pointed in the right direction. I have perused tutorials, links, forums and recently bought the jQuery Cookbook (I needed SOMETHING to go on and it was one of the few jQuery books at the local bookstore that felt as though it would be of help). My problem is, I am finding gaps in information that, to me, are critical to learning. I am looking for a nut-and-bolt approach, 'Do this, then do that' not the typical generalizations I keep encountering.
All I want to do to start with is to remotely validate a two-item form, you guessed it, username and email, against the contents of my database (the info for the validation plugins is just as vague and general). That's it. But the tutorials and examples are vague to me, and in one instance, a link was posted offering to display the server-side validation code used and the link was dead. I can't be the only person here who is stonewalled by these thoughtful, yet overly-general tutorials and books. if any of you have suggestions where I can find a concise, true step-by-step tutorial or book, I would love to know. Right now, it's just one frustrating day of research after another.
i have 2 fields in my form with 1 being currently validated with aremote method (say Field B).I would like to make a dependency between fieldA and fieldB so i triedto add a blur function on field A with jQuery("#FieldB").valid()but when i change FieldA's value no remote validation occurs becausethere is a check (if value != previous value)is there a way for me to disable this cache
I've got some strange behavior with validation. I'm loading up a form to allow editing of an existing database entry. If I make my changes to the fields, enter in the required "revision comments" and submit, the page does NOT post, it seems to only refresh and empty out all the entries in each of the fields. Now, on the other hand if I open the form to make changes to a database entry and immediately press "Submit" without filling in the revision comments field, it fails validation and tells me to enter comments. Now if I fill in comments to satisfy all the requirements and press submit, it posts and I get my "Successful Entry" confirmation prompt. I think I've narrowed it down to the remote: part of my jQuery. I eliminated by trial-and-error the other pieces of the jQuery code and it seems that when I remove the remote: it does not experience this strange behviour.
jQuery Code: [code] // Form Validation customization $("#Form_business").validate({ rules: {
