The
<html:checkbox> element

The
<html:checkbox> element is used with an associated property of
typ boolean. It renders a HTML <input> element of typ checkbox.

The
following example shows the source code of the JSP file.

&lt;html:checkbox property="checked"&gt;Label&lt;/html:checkbox&gt;




The
following HTML source code is rendered at runtime.


<input type=“checkbox” name=“checked” value=“on”>Label


<html:multibox>


The
<html:multibox> element
is used to manage multiple checkbox elements, for example in lists.
The value, which will be transfered to the server from a selected
checkbox, can be any value of type string. The associated property in
the form-bean is an array of type string, which holds a list of
selected values after submitting the form.


The
following examples shows the source code of the JSP file:


<html:multibox property=“selectedItems” value=“1”> Maria

The
<html:select> element


The
<html:select> renders a HTML <select>
element. A property of a form bean associated with this element,
which holds the value if the element is submitted to the server


The
<html:select> element works in two different modes:




The
following example shows the source code of the jsp file.

&lt;html:select property="selectedItem"&gt;<br>	&lt;html:option value="Maria"&gt;Maria&lt;/html:option&gt;<br>	&lt;html:option value="Klaus"&gt;Klaus&lt;/html:option&gt;<br>&lt;/html:select&gt;




The
following HTML source code is rendered at runtime.


<select name=“selectedItem”>
	<option value=“1”>Marie</option>
	<option value=“2”>Klaus</option>
</select>

The
<html:option> element


The
<html:option> element is a part of the <html:select>
element and must be nested inside this element. It can be used
multiple times inside the <html:select> element. The
<html:option> renders a HTML <option> element at
runtime.

The
following example shows the source code of the JSP file:

&lt;html:select property="selectedItem"&gt;<br>	&lt;html:option value="Marie"&gt;Marie&lt;/html:option&gt;<br>	&lt;html:option value="Klaus"&gt;Klaus&lt;/html:option&gt;<br>&lt;/html:select&gt;




The
following HTML source code will be rendered.


<select name=“selectedItem”>
	<option value=“Marie”>Marie</option>
	<option value=“Klaus”>Klaus</option>
</select>

The
<html:options> element


The
<html:options> element is only valid when nested inside
a <html:select> element. Renders a HTML <option>
element. The element is used to display data of lists (arrays,
collections) inside a select element. This tag can be used multiple
times within a single <html:select> element.


The
following example shows the source code of the JSP file.


<html:select property=“selectedItem”>
	<html:options collection=“customers” property=“id” labelProperty=“name” />
</html:select>





The
following HTML source code is rendered at runtime.


<select name=“selectedItem”>
	<option value=“1”>Marie</option>
	<option value=“2”>Klaus</option>
</select>

The
<html:optionscollection> element


The
<html:optionscollection> element is only valid nested
inside a <html:select> element. It renders a HTML
<option> element. The <html:optionscollection>
element is used to output lists (arrays, collections) for a HTML
select field. This tag differs from the <i><span >&lt;html:options&gt;</span></i>
tag in that it makes more consistent use of the <i><span >name</span></i>
and <i><span >property</span></i>
attributes, and allows the collection to be more easily obtained from
the enclosing form bean.


The
following examples shows the source code of the JSP file:


<html:select property=“selectedItem”>
	<html:options collection=“customers” value=“id” label=“name” />
</html:select>





The
following HTML source code is rendered at runtime:


<select name=“selectedItem”>
	<option value=“1”>Marie</option>
	<option value=“2”>Klaus</option>
</select>


The
<html:radio> element


It
renders a HTML <radio> Element. You assign a property of the
form-bean to this element. <html:radio> elements with
the same property will be grouped. It is possible to use a
<html:radio> element inside an iteration.



The
following example shows the source code of the JSP file:


<html:radio property=“selectedItem” value=“Maria” />
<html:radio property=“selectedItem” value=“Klaus” />





The
following HTML source code will be rendered.


<input type=“radio” name=“selectedItem” value=“Maria”>
<input type=“radio” name=“selectedItem” value=“Klaus”>
