I'm developing a framework that allow all navigation in normal mode or in ajax load.
I have a form to upload images and I can upload files correctly, but if I use the ajax form, the save page don't receive the HTTP_X_REQUESTED_WITH in $_SERVER PHP array (only occours when a file is uploaded).
How can I detect an ajax load with a file upload form?
With my current javascipt code I have successfully implemented jQuery Form Plugin with my own page. It hooks forms and submits them, and upon either failure or success the proper function is fired (success and error options of ajaxForm) and the XML is handled.
However, whenever I add a <input type="file"> my code fails to determine wether or not an error occured, since the HTTP code of the request seems to be set to 0, and thereby somehow being treated as "success" event, which it clearly isn't, as the PHP returning the XML sends a HTTP 400. (Firebug confirms this.)
Simply put, why does the file upload cause a 100% "success"-rate with HTTP status 0 where it shouldn't, and how could I work around this if required?

I'm doing some ajax image uploads using the plugin at [url] I have multiple images on the page which I will be replacing with the uploaded image. My problem is this, trying to refer to the clicked image within the onComplete function.
I tried creating a variable that refered to 'this' which I beleive to be the image element but when I make the change to the element it is not refected, making me think that the variable is a copy and not a reference ?
The user needs to upload files, but the number of files they need to upload is variable.
I've got something like this:
function another_file() {
document.getElementById('files').innerHTML += '<input type="file" class="fileinput" name="pictures[]" />'
}
But everytime I click on the link that calls that function, it erases the previous input's state. I'm after something like GMail's attachments interface.
Script works on the first attachment but not the other two?
<script type="text/javascript" language="JavaScript"><!--
function ExtensionsOkay() {
var extension = new Array();
var fieldvalue = new Array();
fieldvalue[0] = document.customApp.attachment_1.value;
fieldvalue[1] = document.customApp.attachment_2.value;
fieldvalue[2] = document.customApp.attachment_3.value;
extension[0] = ".doc";
extension[1] = ".docx";
extension[2] = ".txt";
extension[3] = ".pdf";
// No other customization needed.
for(var f = 0; f < fieldvalue.length; f++) {
var thisext = fieldvalue[f].substr(fieldvalue[f].lastIndexOf('.'));
for(var i = 0; i < extension.length; i++) {
if(thisext == extension[i]) { return true; }}
alert("Your upload field " + f + " contains an unapproved file name.");
return false;
}}
//--></script>
I have a form where a user can upload a file. I do a check to see if it's a zip file. If it isn't then its supposed to stop the file from being uploaded. Only thing is, the file still uploads regardless of getting the error or not.
How can I prevent the form from submitting the file if the error pops up?[code]...
in Gmail (I've noticed it in other services too..)after you log in, progress bar appears. What does it do? Uploads all the JS(containing ajax) files into client's machine? or what?

View 2 Replies View RelatedI've tried searching for this under the forums — and maybe it's because I just am using the wrong terms — but I cannot find any answers around this. Here's the skinny:
I've got a listener for click events from links in DIV #1 in the loaded document, and when a user clicks on one of those links, it passes a value to a .get() function and runs a simple AJAX call and dumps the data/html results into DIV #2.
After that click event, DIV #2 has a bunch of links in it, and I'm trying to traverse that dynamically assembled list and perform another .get() function based upon whatever link they click in DIV #2.
Based on the parameter passed from the link in the dynamically assembled DIV #2 box, it would run the .get() function and fill DIV #3 with the data/html results from that second AJAX call. The problem is that I can't seem to detect any sort of click event from the contents of DIV #2 aside from clicking on DIV #2 itself. I've tried the usual .children() to try and traverse down to where the inserted links would be, but that's not working (e.g.: $("#div2").children("a").click(); ). I've also tried .find(), filter() and .has() but it doesn't respond, as if there was nothing there.
Here's the code I'm working with:
<div id="album_row">
<a href="#" rel="1">Album 1</a>
<a href="#" rel="2'>Album 2</a>
</div>
[Code].....
I have a feeling it's something simple that I'm missing here; but I've no clue what I'm doing wrong. It seems that you should be able to traverse the DOM, even when you're essentially building it dynamically based upon a user's selection or an event within the DOM.
what I should be using to use to detect click() events from dynamically assembled elements? I know exactly what DIV they'll be sent to, I just can't seem to traverse anything with them when I'm dynamically inserting HTML into them.

View 2 Replies View RelatedDoes anybody knows a good jQuery multiple file uploader? The idea is when somebody click on the Upload link some kind of popup box needs to appear. Something like the media uploader in WordPress. The background of the website becomes grey, and only a upload box appear. It would be cool that only if you have selected one file, the next input for a new upload appear with a max of 9 uploads at a time ...

View 6 Replies View RelatedThe system uses individual PDF files for each page, and you can navigate using the controls on the side. It's not ideal, as it was made to replace a horrible system and has the limitations of the content being presented.
That being said, I think it's pretty good. The trouble area is related to navigation: when you navigate the documents, some JavaScript detects the current URL of the content frame and updates the nav controls (previous and next page numbers) and table of contents links (bold, highlight) if they have changed. That part works fine. The problem area is with IE and PDF links. If you click a page link within the PDF, it opens that PDF file in the same frame. In FF and every other browser, the JS URL detection works fine.
In IE, of course, it doesn't detect that a different PDF is being displayed. If it can't detect the new PDF file, and by extension, the file number, the nav controls don't work right. Now - before anyone asks - it DOES work in IE if you navigate to the PDF document by using the links in the navigation system that I built. It's just when you arrive at a PDF from another PDF that it fails.
This is hard to explain more clearly, so take a look: [URL]
To see this in action, visit page 4, the table of contents. Click a page number link, for instance, page 9. Once it loads, click "next page" at the top left of the interface. In FF, it goes to page 10. In IE, it goes to page 5, since the JavaScript is unaware that the frame has changed PDF files. It doesn't make sense, since FF can see it plainly.
My code is all out in the open. This thing has to be designed to run off of a CD as well as on the website. If I could use server-side scripting, it would be VERY different, I assure you.
I'm building an application that calculates the total price of items when adding them up and displays it in a particular div tag called "totalCost" using AJAX. But sometimes it might take long to calculate (due to server response time or something else) and that could annoy clients. I just want to detect when the AJAX takes long to display the new total price, so I can show a message like "Calculating, please wait..." or an image (a clock, sandglass, etc...) as an overlay.
Please, how do I do that in javascript?
I implemented Malsups jquery form and use it for ajax file uploads. Works fine in FF, but in IE as soon as the ajax has completed the upload IE gives me a File Download box - Security warning. If I click on save it save thereturnedJson object (I do JS call onsuccessto get a file list and display it). If I click cancel or save on the popup has same effect the file still gets uploaded but just looks ugly.
How can I get rid of this? All coming form the same domain, calling from the same domain. This is on a python django project and I am testing it on the dev server.
Its pretty basic jquery nothing to exciting, don't get why IE would cause.
I'm working on a website, where a fixed <div> holds the menu and links id's on the page with <a href="#">'s - like this:
HTML Code:
I'm wondering if it's possible to detect which of the <h1 id="i1">Item1</h1>'s that's currently shown on in the browser window? My idea is to highlight the menu-link(s) (e.g. by changing color) of the items headings shown in the browser window (so it changes as the user scrolls down through the page)?
I've already developed a system for doing this which isn't perfect i'm wondering if there is a better solution. Here is the code I got atm.

I don't like the use of key == 8 and length == 1 to detect that chatmsg box is empty, but the event triggers before the val() of the chatmsg actually changes. So is there nothing better I can do?
when uploading multiple files with php, one uses an array for the name of the file field like this: <input name="image[]" type="file" id="1" size="40">
Now I have some genius jscript that checks the file types of multiple upload fields. But it requires the name of each of the fields to be unique. Since all my fields have image[] for the name - the script breaks. If I name my fields with image1, image2, image3 etc, the jscript works.
In order to upload multiples, php requires the name of the field to be an array as above. I just need a little tweak to this jscript!
Here is the jscript. pretty simple, except for when the field is called using it's "name" property midway down. I tried using unique id's but this didn't seem to work - of course I might have messed it up. Code:
