A page can contain information that is static and those that are dynamic. Static means that the information presented tends to remain, if you want to change the information has to change its program. While that is dynamic, the information can be changed without having to change the program. To create a web that is dynamic, we need the existence of supporting components. The required supporting components may be text input and can also be the execution and usually presented in a form. To be able to use existing components on the form, it takes a special mastery of the relevant HTML code. In this chapter will be studied using the codes forming a form.
Basic Use of Forms
In a web page sometimes we come across a guest book for visitors, feedback and member registration. Among the three forms of the view must have used a form component. To form a necessary form tag pair <form> and </ form>. And use the support form the action attribute and method.
• ACTION is used to determine the destination if a button on a form is run ..
• METHOD used to determine the technical delivery of information after the run button to access or send an information. Generally the method consists of two types of get and post. When using get meaningful information displayed will be obtained on the page itself in this case the url in the action. While the post that information will be sent separately from the url.
For more details, use the action and the method can be seen on pieces of the following programs:
<Form action = "send.html" ">......</ form method = post>
A. Tag Input In Form
To input a data or text required a clear area. Area there are many different forms in the form of a field there is also a small box or circle a way to fill it simply by clicking on the area and there are still other forms. To shape it takes on the form tag and some attributes <input> supporters and to be located in pairs <form> tag and </ form>. Input tag has several attributes. Attributes as shown in the following table:
NAME = To determine the name of the data
SIZE = size Specifies the input box for text and password
MaxLength = Specifies the amount of text can be entered in a particular area such as the input text and password
VALUE = Provide initial values ??for the input box before starting the new text entered
CHECKED = Given that in a state of selected check boxes.
TYPE = Specifies the type of input box, such as passwords, text, submit, reset, etc.
The following example shows the use of a form that involves a text field, submit button and reset.
type the script below and save it as
form.html :
<html>
<head>
<title> form </ title>
</ Head>
<body>
<form ="information.html" action method = "post">

<input type = "text" name="nama" size = "20" MaxLength = "20">

<br>
<input type = "submit" value = "Kirim">
<input type = "reset" value = "Clear">

</ Body>
</ Html>
To address that if the submit button is clicked then the HTML file named in the action attribute on the tag will be loaded <form> .. Once you learn PHP, ASP or other web database, you will know how to capture the values ??entered in the second text field above.
