Step 1: Design a form look include a text box,
check box, and buttons.
| <form action="" method=""
name=""> <input type="text" size="10" name=""> <input type="checkbox" name="" value="ON"> <input type="submit" value="Add"> <input type="reset" value="Clear"> </form> |
Step 2: Give the form and the input types a name.
*Very Important*
| <form action="" method=""
name="formname"> <input type="text" size="10" name="textname"> <input type="checkbox" name="checkboxname" value="ON"> <input type="submit" value="Add"> <input type="reset" value="Clear"> </form> |
Step 3: Add the onclick tag in the checkbox.
Make the value
"codename()". *Very Important*
| <form action="" method=""
name="formname"> <input type="text" size="10" name="textname"> <input type="checkbox" onclick="codename()" name="checkboxname" value="ON"> <input type="submit" value="Add"> <input type="reset" value="Clear"> </form> |
Step 4: Now we want to make the text box disabled.
Add the disabled in the
text box.
| <form action="" method=""
name="formname"> <input type="text" disabled size="10" name="textname"> <input type="checkbox" onclick="codename()" name="checkboxname" value="ON"> <input type="submit" value="Add"> <input type="reset" value="Clear"> </form> |
Step 5: Now we need to enable it with the checkbox using a small java script. Add the following code above the form. The script is case sensitive meaning you can only use lowercase.

<SCRIPT LANGUAGE="JavaScript"><!-- |
| This code is also useful when you don't want to send empty values. It allows you have a option. Example: using form method GET (http://www.host.com/index.asp?formname=&checkboxname=ON) without code Example: using form method GET (http://www.host.com/index.asp?) with |
