The document discusses HTML forms and how they are used to collect user input on web pages. It provides examples of common form elements like text fields, buttons, checkboxes, radio buttons, and drop-down menus. It also explains how forms work with tags like <form> and <input> and attributes that define behaviors and properties of the elements. JavaScript can be used to add interactivity and validate user input in forms.

What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
Introduction to JavaScript course. The course was updated in 2014-15.
Will allow you to understand what is JavaScript, what's it history and how you can use it.
The set of slides "Introduction to jQuery" is a follow up - which would allow the reader to have a basic understanding across JavaScript and jQuery.

HTML5 is a language for structuring and presenting content for the World Wide Web. it is the fifth revision of the HTML standard (created in 1990 and standardized as HTML4 as of 1997) and as of February 2012 is still under development. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). It improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors
Open Source and Open Data in the Age of the CloudTim O'Reilly
Another of my "State of the Internet Operating System" talks, this one given at the MySQL User Conference on April 14, 2010. A bit more of a focus on open data.
Animations on the web have a storied history and no consistent approach. Using CSS animations is still considered an experimental technology but much can be created already. In this talk, we will explore how to create beautiful CSS animations, cover the compatibility between different browsers, share some ready-libraries for quickly animating your elements and share tools to help you build animations faster.
In this slide I described all control which is used by the Html Form Controls such as checkbox , radio , text , drop down list / select , file upload and html output controls.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?

2. What are forms?
<form> is just another kind of HTML tag
HTML forms are used to create (rather primitive) GUIs on Web
pages
Usually the purpose is to ask the user for information
The information is then sent back to the server
A form is an area that can contain form elements
The syntax is: <form parameters> ...form elements... </form>
Form elements include: buttons, checkboxes, text fields, radio buttons,
drop-down menus, etc
Other kinds of HTML tags can be mixed in with the form elements
A form usually contains a Submit button to send the information in he
form elements to the server
The form’s parameters tell JavaScript how to send the information to
the server (there are two different ways it could be sent)
Forms can be used for other things, such as a GUI for simple programs
2
3. Forms and JavaScript
The JavaScript language can be used to make pages that “do
something”
You can use JavaScript to write complete programs, but...
Usually you just use snippets of JavaScript here and there
throughout your Web page
JavaScript code snippets can be attached to various form elements
For example, you might want to check that a zipcode field contains a 5-
digit integer before you send that information to the server
Microsoft sometimes calls JavaScript “active scripting”
HTML forms can be used without JavaScript, and
JavaScript can be used without HTML forms, but they work
well together
JavaScript for HTML is covered in a separate lecture
3
4. The <form> tag
The <form arguments> ... </form> tag encloses form
elements (and probably other HTML as well)
The arguments to form tell what to do with the user
input
action="url" (required)
Specifies where to send the data when the Submit button is clicked
method="get" (default)
Form data is sent as a URL with ?form_data info appended to the end
Can be used only if data is all ASCII and not more than 100 characters
method="post"
Form data is sent in the body of the URL request
Cannot be bookmarked by most browsers
target="target"
Tells where to open the page sent as a result of the request
target= _blank means open in a new window
target= _top means use the same window
4
5. The <input> tag
Most, but not all, form elements use the input tag, with a
type="..." argument to tell which kind of element it is
type can be text, checkbox, radio, password, hidden, submit,
reset, button, file, or image
Other common input tag arguments include:
name: the name of the element
value: the “value” of the element; used in different ways for
different values of type
readonly: the value cannot be changed
disabled: the user can’t do anything with this element
Other arguments are defined for the input tag but have meaning
only for certain values of type
5
6. Text input
6
A text field:
<input type="text" name="textfield" value="with an initial value">
A multi-line text field
<textarea name="textarea" cols="24" rows="2">Hello</textarea>
A password field:
<input type="password" name="textfield3" value="secret">
• Note that two of these use the input tag, but one uses textarea
7. Buttons
A submit button:
<input type="submit" name="Submit" value="Submit">
A reset button:
<input type="reset" name="Submit2" value="Reset">
A plain button:
<input type="button" name="Submit3" value="Push Me">
submit: send data
reset: restore all form elements to their
initial state
button: take some action as specified by
JavaScript
7
• Note that the type is input, not “button”
8. Checkboxes
A checkbox:
<input type="checkbox" name="checkbox”
value="checkbox" checked>
type: "checkbox"
name: used to reference this form element from JavaScript
value: value to be returned when element is checked
Note that there is no text associated with the checkbox—you
have to supply text in the surrounding HTML
8
9. Radio buttons
Radio buttons:<br>
<input type="radio" name="radiobutton" value="myValue1">
male<br>
<input type="radio" name="radiobutton" value="myValue2" checked>
female
If two or more radio buttons have the same name, the user
can only select one of them at a time
This is how you make a radio button “group”
If you ask for the value of that name, you will get the value
specified for the selected radio button
As with checkboxes, radio buttons do not contain any text
9
10. Drop-down menu or list
A menu or list:
<select name="select">
<option value="red">red</option>
<option value="green">green</option>
<option value="BLUE">blue</option>
</select>
Additional arguments:
size: the number of items visible in the list (default is "1")
multiple: if set to "true", any number of items may be selected
(default is "false")
10
11. Hidden fields
<input type="hidden" name="hiddenField" value="nyah">
<-- right there, don't you see it?
What good is this?
All input fields are sent back to the server, including hidden fields
This is a way to include information that the user doesn’t need to see
(or that you don’t want her to see)
The value of a hidden field can be set programmatically (by JavaScript)
before the form is submitted
