Form enctype Property
 Form Object
Definition and Usage
The enctype property sets or returns the value of the enctype attribute in a form.
The enctype attribute specifies how form-data should be encoded before sending it to the server.
The form-data is encoded to "application/x-www-form-urlencoded" by default.
This means that all characters are encoded before they are sent to the server
(spaces are converted to "+" symbols, and special characters are converted to ASCII HEX values).
Syntax
The enctype property can have one of the following values:
| Value |
Description |
| application/x-www-form-urlencoded |
All characters are encoded before sent (this is default) |
| multipart/form-data |
No characters are encoded. This value is required when you are using
forms that have a file upload control |
| text/plain |
Spaces are converted to "+" symbols, but no special characters are
encoded |
Browser Support
The enctype property is supported in all major browsers.
Note: Internet Explorer and Safari returns "application/x-www-form-urlencoded"
even if no enctype attribute is defined (this is the default value), while the
other browsers return nothing.
Example
