Submit Tag (Form Tag) Example
In this section, we are going to describe the submit
tag. The submit tag is a UI tag that is used to render a submit button. The
submit tag is used with the form tag to provide asynchronous form
submissions. The submit can have three different types of rendering:
- input: renders as html <input
type="submit"...>
- image: renders as html <input
type="image"...>
- button: renders as html <button
type="submit"...>
Add the following code snippet into the struts.xml
file.
struts.xml
<action name="submitTag">
<result>/pages/uiTags/submitTag.jsp</result>
</action> |
Create a jsp using the tag <s:submit>
that renders a submit button. This tag contains various parameters:
The value parameter
presets the value of input element. In our 1st case we have set it to "Submit"
The type
parameter sets the type of submit to use. Valid values are
input, button and image. In our case we have set it
to "image"
The src
supplies an image src for image type submit button.
It will have no effect for types input and button. In our case we have set it
to:"/struts2tags/pages/uiTags/submit.gif"
The align
sets HTML
align attribute. In
our case we have set it to:"center"
