In lesson 7 of the HTML Intermediate Tutorials we took a first look at forms, and introduced the <input>, <label> and <textarea> tags for use inside the <form></form> element. In this lesson we take a final look at forms with the remaining HTML tags we haven't used for form entry so far.

The <button> Tag

The <button> tag and its' closing </button> tag are used to define a push button.

The <fieldset> Tag

The <fieldset> tag and its' closing </fieldset> tag are used within the <form> </form> element to define a form control group.

The <legend> Tag

The <legend> tag and its' closing </legend> tag should be placed after the opening <fieldset> tag to define a caption for the fieldset.

The <optgroup> Tag

The <optgroup> tag and its' closing </optgroup> tag are used within the <select> </select> element to group related options together.

The <option> Tag

The <option> tag and its' closing </option> tag are used within the <select> </select> or <optgroup> </optgroup> element to define a selectable option.

The <select> Tag

The <select> tag and its' closing </select> tag are used to create a drop down list of selectable options.

Viewing The Tags

Reviewing Our Changes

The Form

The <form> element encloses the other tags we wish to use in our forms and we used this tag with its' action and method attributes. The action attribute tells the browser which URL to invoke when the user submits the form. The method attribute tells the browser how to submit the form data.

Fieldset

We have used the <fieldset></fieldset> element to group the elements within the form together.

Legend

We have used the <legend></legend> element to give a caption to the elements grouped within the <fieldset></fieldset> element. We called the caption 'Pie Survey'.

Text Input

We have used the <input> tag along with its type attribute to allow the user to enter their name. We did this by setting the value of the type attribute to text. The name attribute was used to pass the value of the text entered to the server.

Radio Button Input

We also used the <input> tag along with its type attribute to allow the user to select a radio button. We did this by setting the value of the type attribute to radio. The checked attribute was used to set an initial value for the radio buttons. The name attribute was used to pass the value attribute of the radio button selected to the server.

Label Input

We used the <label> tag to give each radio button a name. We also used the for attribute to allow the user to select a radio button by using the mouse to click on the text. The for attribute of the <label> tag must match the id attribute of the <input> tag to bind the two together and allow this usability with the mouse.

Selection (drop-down menu) Input

We used the <select></select> element to create a drop-down selectable menu. We used the <colgroup></colgroup> element within the <select></select> element to group together selectable <option></option> elements. The name attribute was used to pass the value attribute of the selection to the server.

Entering Data

Use the mouse to click in the name field and enter some input. Also maybe click a different radio button and select something from the drop-down list. Following is an example:

Submit the data

Use the mouse to click the submit button and a screen similar to the following will appear:

Reviewing Our Changes

As you can see the information we entered has been passed across and rendered on the screen. How the information was passed across is beyond the scope of these tutorials but take a look at Learn jQuery - Ajax Low-Level Interface Lesson and the other Ajax lessons on that site for more information about this.

Lesson 6 Complete

Modify the HTML to create your own forms until you're confident with all aspects of form creation.
