I have a JSP page and in that I am using Struts2 tags for making my registration form.
Now the first field is type which uses s:select
tag. Now, depending on what is selected by the user I want to load next texfields on the same page below the select box. How can I do it? Here is my approach but it's not working.
<s:form action="clientAction" method="post">
<s:select name="type" label="Registration Type"
list="{'Student','Faculty'}" emptyOption="false" />
<s:if test="type.equals(Student)">
<s:textfield label="FirstName" name="s_fname"/>
<s:textfield label="LastName" name="s_lname"/>
<s:textfield label="UserName" name="s_username"/>
<s:password label="Password" name="s_password"/>
<s:textfield label="EmailId" name="s_email_id"/>
</s:if>
<s:if test="type.equals(Faculty)">
<s:textfield label="FirstName" name="fac_fname"/>
<s:textfield label="LastName" name="fac_lname"/>
<s:textfield label="UserName" name="fac_username"/>
<s:password label="Password" name="fac_password"/>
<s:textfield label="EmailId" name="fac_email"/>
<s:textfield label="Course Name" name="course_name"/>
<s:textfield label="Course Id" name="course_id"/>
</s:if>
<s:submit/>
</s:form>
You could do it with JQuery, and you don't need to load fields from the server, as well as mess up JavaScript code with JSP code. You should use css_xhtml
theme to hide/show fields on change event of select box. Like in this example
<s:form action="clientAction" method="post" theme="css_xhtml">
<s:select id="RegistrationType" name="type" label="Registration Type"
list="{'Student', 'Faculty'}" emptyOption="false" />
<s:div id="Student" cssStyle="display: none;">
<s:textfield label="FirstName" name="s_fname"/>
<s:textfield label="LastName" name="s_lname"/>
<s:textfield label="UserName" name="s_username"/>
<s:password label="Password" name="s_password"/>
<s:textfield label="EmailId" name="s_email_id"/>
<s:submit/>
</s:div>
<s:div id="Faculty" cssStyle="display: none;" >
<s:textfield label="FirstName" name="fac_fname"/>
<s:textfield label="LastName" name="fac_lname"/>
<s:textfield label="UserName" name="fac_username"/>
<s:password label="Password" name="fac_password"/>
<s:textfield label="EmailId" name="fac_email"/>
<s:textfield label="Course Name" name="course_name"/>
<s:textfield label="Course Id" name="course_id"/>
<s:submit/>
</s:div>
</s:form>
<script type="text/javascript">
$(document).ready(function(){
$('#RegistrationType').change(function(){
$('#'+this.value).css('display', 'block');
if (this.value=='Student') $('#Faculty').css('display', 'none');
else $('#Student').css('display', 'none');
});
});
</script>
