The Password Widget
- A Password Widget is simply a Text Field in which the user data is masked so that nobody looking over the user's shoulder can read what was typed in. Try out the following example:
Behind the scenes, the above password field was created with the following HTML code
<FORM> <INPUT TYPE = "PASSWORD" NAME = "pass" > </FORM>
| It is important to know that this field does not offer any form of real security. The value typed in to the password widget is still sent over the internet as unencrypted plain text. The only security this widget offers is the security of preventing an office worker from looking over your shoulder. |
- The Password widget also has several other attributes which affect how it works. The following table outlines them:
| Attribute | Description |
|---|---|
| TYPE | Specifies the type of interface widget. For a password widget, you use "PASSWORD" |
| NAME | Specifies the variable name associated with this widget |
| VALUE | Specifies initial default text which should appear in the password field |
| MAXLENGTH | Specifies the maximum number of characters allowed to be input into the widget |
| SIZE | Specifies the width of the field |
- Let's take a closer look at each of these attributes.
- The VALUE attribute allows you to specify default text. Here is an example:
And here is the code which we used to make that password field.
<FORM> <INPUT TYPE = "PASSWORD" NAME = "password" VALUE = "default text" > </FORM>The MAXLENGTH Attribute
- The MAXLENGTH attribute allows you to specify the maximum number of characters allowed for input. Here is an example which only allows you to type in 5 characters. Try it out for yourself:
And here is the code which we used to make that password field.
<FORM> <INPUT TYPE = "PASSWORD" NAME = "demo" MAXLENGTH = "5" > </FORM>The SIZE Attribute
- The SIZE attribute allows you to specify the width of the text field itself. Here are two examples which show the attribute being used:
And here is the code which we used to make the password fields.
<FORM> <INPUT TYPE = "PASSWORD" NAME = "demo" SIZE = "30" > <INPUT TYPE = "PASSWORD" NAME = "demo" SIZE = "20" > </FORM>
