FORMs Lesson TBE 540 Prerequisites Before beginning this lesson, the learner must be able to… – Create basic web pages using a text editor and/or a web page editor. – If using a web page editor, edit the HTML Source. Objectives After completing all lesson-related activities, the learner will be able to… – Create a form and include it in a web page. Forms Forms are used to add interactive elements to a web page. Forms allow you to put in buttons, pulldown menus and input fields for the user. Using JavaScript, you can customize actions for buttons, menus and input fields. Form Tags All forms begin with <FORM> and end with </FORM>. The <FORM> tag may contain a method (POST or GET) and an action. Here is a sample (information will be placed in a message (POST) sent to ffisher@csudh.edu): <FORM method="POST" action=“mailto:ffisher@csudh.edu”> Form Tags How does the information get into the message? Through buttons, menus and fields. Each type of input has a special tag. These tags specify the type of input (text field, button, text area, menu), the name of the input that comes in (e.g., “Firstname”), and sometimes the value (which button was pressed?) Form Tags - Samples Radio button: <INPUT TYPE=“RADIO” NAME=“GENDER” VALUE=“FEMALE”> Checkbox: <INPUT TYPE=“CHECKBOX” NAME=“STUDENT” VALUE=“YES”> CLICK ME Button: <INPUT TYPE=“BUTTON” VALUE=“CLICK ME” ONCLICK=“begin_game()”> Form Tags - Samples Text field/box: <INPUT TYPE=“TEXT” NAME=“FIRSTNAME”> Enter Text area: <TEXTAREA NAME=“MSG” ROWS=5>Enter</TEXTAREA> Form Tags - Samples Pull-down menu: <SELECT NAME=“AGE”> <OPTION SELECTED>Old <OPTION>Young <OPTION>Never mind! </SELECT> Old Old Young Never mind! Form Tags - Samples If the information is to be sent (i.e., the “action” will be taken), there will be a SUBMIT button. Submit Sample tag: <INPUT TYPE=”SUBMIT" VALUE="Submit" NAME="Submit Button"> When clicked, the action described in the FORM tag will be initiated. Form Tags - Samples You may also want to have a RESET button Reset Sample tag: <INPUT TYPE=”RESET" VALUE=”Reset" NAME=”Reset Button"> When clicked, all the fields are cleared. Form Tags See http://www.csudh.edu/fisher/tbe540/HH O6.htm for specific examples.
