Can JQuery File upload be used without AJAX? - file-upload

I want to use something along the lines of JQuery file upload (i'm open minded) in a form with lots of other fields for the UI (ex. image previews, delete, file sizes .etc), but I want to submit the files along with the form as if i used a normal HTML file field.
Is this at all possible?

If you console.log() the form after submission you will get an object in return that has a bunch of information. Among that information you can find for example file information of the file you just upload.
You can check this http://jsfiddle.net/1r0Lprkj/1/ and open your console after you've submitted the form.
Then if you want to go deeper into this, then you can check out the Javascript FileReader which lets you do a bunch of cool stuff with the uploaded file. https://developer.mozilla.org/en-US/docs/Web/API/FileReader
To answer your question; Yes it is possible to achieve without AJAX.

a visual tool for upload status of file in BigCommerce

BigCommerce allows for product options that a user can upload a file to attach to an order (think a business card printer needs art files uploaded to the order)
Once a user selects all the options, and clicks add to cart, the page uploads the selected file along with the order details and takes you to the shopping cart. The time it takes for it to load depends on the weight of the files being uploaded.
Does anyone have a solution for having a visual tool for while a file is uploading, a percentage (either bar, or numbers) can be shown (or simply a "uploading images" overlay). People who are not familiar with the site think the page has frozen - they only realize when they let it upload - sometimes files can take up to 30 seconds to upload.
Im fairly proficient at CSS and HTML5 - if there are any solutions, please advise.
Thanks!

In this case, you'd need to add HTML and CSS to create and style the loading bar. For the actual function of checking the upload status and displaying the progress, I'd suggest using jQuery with form plugin (uploadProgress function).
The necessary steps required to accomplish this will be a bit different in Bigcommerce than you'd see in this blog post, but it is explains it in a bit more depth with examples

How to add a custom image (<xh:img>) to PDF

We would like to add an image to our PDF in Orbeon. We explorered different tags and came up with tag. This worked the way we wanted but this tag keeps the PDF from building. We don't get any (visible) errors but a time-out occurs after couple of seconds.
To cross check: PDF build fine without the xh:img tag.
I was wondering what other options do we have. I thought about a PDF template but we would like to give the form author the option to choose his/hers own jpg from a web resource.
This is on 43PE.
User error yet we didn't change much after all.

Disable browser cache for displayed in an iFrame PDF by means of TCPDF

I am trying for hours to solve the following caching problem.
My application has the following structure (simplified):
index.php - main page (contains various input fields, submit button and an iframe for dispaying PDF content with the help of TCPDF)
generate.php - generates PDF file based on the supplied POST parameters and stores the file to the filesystem
viewer.php - Displays the PDF document (TCPDF libraries). The iframe loads this script to show the pdf file
The workflow is pretty simple - the user chooses some options and clicks the submit button on the main page. The selected parameters are sent per AJAX by POST to the generate.php script. The script generates the PDF file and stores it to the filesystem. At the end it returns the newly created/edited filename. The filename is fetched in the AJAX callback function, which then refreshes the iframe with the new/edited filename:
viewer.php?filename=NEW_OR_EDITED_FILENAME
Everything is working, but when the file is being replaced, sometimes (NOT ALWAYS), the browser shows the old pdf file, although the new version is on the hard drive. I tried the following solutions:
Add Meta tags to disable cache to the generated HTML by index.php and viewer.php
Disabling cache for jQuery AJAX calls by: jQuery.ajaxSetup({cache: false});
Adding some random string to the the filename parameter:
viewer.php?filename=FILENAME_RANDOMSTRING
The RANDOMSTRING is then removed from the script and the filename is extracted.
None of these solutions worked for me. Tested browsers are: Chrome 25.0.1364.152 and Firefox 19.0. Can someone help me with this?
Thanks in advance
Just had the same problem but after adding a random string it works perfect:
<iframe src="file.pdf?=<?=time();?>"></iframe>
After many hours of trying, the solution I found is to really generate a new file each time (Solution 3 from the question without removing the random string at the end of the file). As a result it was necessary to update the database and to delete the old files on every change. My initial intention was to avoid these actions, but unfortunately no other solution was found

how to read/parse dynamically generated web content?

I need to find a way to write a program (in any language) that will connect to a website and read dynamically generated data from the website.
Note that it's dynamically generated--it's not enough to get the source html, because the data I'm interested in is generated via javascript that references back-end code. So when i view the webpage source, I can't see the data. (For example, go to google, and do a search. Check the source code on the search results page. Very little of the data your browser is displaying is reflected in the source--most of it is dynamically generated. I need some way to access this data.)
Pick a language and environment that includes an HTML renderer (e.g. .NET and the WebBrowser control). Use the HTML renderer to get the URL and produce an HTML DOM in memory (making sure that scripting is enabled). Read the contents of the HTML DOM after the renderer has done its work.
Example (you'll need to do this inside a System.Windows.Form derived class):
WebBrowser browser = new WebBrowser();
browser.Navigate("http://www.google.com");
HtmlDocument document = browser.Document;
// extract what you want from the document
I used to have a Perl program to access Mapguide.com to get the drive direction from one location to another location. I parsed the returned page and save to database. If the source never change their format, it is OK. the problem is the source format often change, your parser also need change.
A simple thought: if we're talking about AJAX, you can rather look up the urls for the dynamic data. Then you can use the javascript on the page you're talking about to reformat this.
If you have Firefox/greasemonkey making a DOM dumper should be a simple matter.

How to upload an image when user selects a file in FileUpload control like in gmail?

I need to upload image or file when user selects that file like in gmail attach file without any other asp:button . What I mean is there shouldn't be any other button except fileupload control. And when a file is selected the file will be uploaded to the server folder.
How to implement that?
Please help.
Take a wee peek at this. Jquery + flash solution.

That is done using JavaScript/AJAX. You can't do it only with ASP.NET controls.
Take a HTML control and use the "onchange" event of this control. Make a asp code file and write the file's upload code on that file. Now use Ajax and to send request to asp's code file.
When you will select file it will automatically upload by ajax. Because Html control events doesn't use server side.
