Display a Form on a button click using struts tags

[Vidya Gupta]

Hi,

I am having a small doubt , that is in my page am having 3 buttons and i want to display a different form when i click on each button. I want to do this by single jsp. Am having a little bit confusion in doing this.

<table align="left" border="0" cellspacing="0" cellpadding="1">
<tr>
<td>
<input type="button" value="button1" onclick="action"/>
<input type="button" value="button2" onclick="action"/>
<input type="button" value="button3" onclick="action"/>
<input type="button" value="button4" onclick="action"/>
</td>
</tr>
</table>

Here for each button it is going to different action methods, in that action method i am writing "return mapping.findForward("") " statement. This statement will forward the action to the same jsp again that contains buttons. Now i want to create a form on button click in the same jsp. am little bit confused that where to write the code to create a form in theis jsp..


Thanks In Advance,
Vidya

from what ever i understood you want to display a form respected to the button clicked by user.
you can add this to your JSP

<table>
		<tr>
			<s:form action="LOADFORM">
				<s:hidden name="s" value="1" />
				<s:submit value="Button1" />
			</s:form>
		</tr>
		<tr>
			<s:form action="LOADFORM">
				<s:hidden name="s" value="2" />
				<s:submit value="Button2" />
			</s:form>
		</tr>
		<tr>
			<s:form action="LOADFORM">
				<s:hidden name="s" value="3" />
				<s:submit value="Button3" />
			</s:form>
		</tr>
		<tr>
			<s:form action="LOADFORM">
				<s:hidden name="s" value="4" />
				<s:submit value="Button4" />
			</s:form>
		</tr>
		<s:if test="formx == 1">Your Form no. 1 inside this</s:if>
		<s:if test="formx == 2">Your Form no. 2 inside this</s:if>
		<s:if test="formx == 3">Your Form no. 3 inside this</s:if>
		<s:if test="formx == 4">Your Form no. 4 inside this</s:if>
	</table>

and inside your struts.xml file

<action name="LOADFORM" class="location of your action class" method="yourmethod">
			<result name="success">loaction of your JSP file</result>
		</action>

inside your action class

String s;
int formx;

	public String yourmethod() {
		System.out.println("s: " + s);
		if (s == "1") {
			formx = 1;
			System.out.println("formx: " + formx);
			return SUCCESS;
		} else {
			if (s == "2") {
				formx = 2;
				System.out.println("formx: " + formx);
				return SUCCESS;
			} else {
				if (s == "3") {
					formx = 3;
					System.out.println("formx: " + formx);
					return SUCCESS;
				}else{
					formx = 4;
					System.out.println("formx: " + formx);
					return SUCCESS;
				}
			}
		}
	}

	public String getS() {
		return s;
	}

	public void setS(String s) {
		this.s = s;
	}

	public int getFormx() {
		return formx;
	}

	public void setFormx(int formx) {
		this.formx = formx;
	}

No.. i don't want to use multiple form:acion attributes in jsp..

My JSP looks like below,

display.jsp
-------------

<html:form action="/file.do?type=display">
	<table border="0" cellspacing="0" cellpadding="0" align="left" width="100%">	
	 <tr>
		<td>
	  		<table border="0" cellspacing="0" cellpadding="2" align="left">
				<tr>
				 <td class="lbl" align="left">City:
				  <html:select name="DisplayForm" property="city" >
					 <html:option value="">--All--</html:option>
					 <html:option value="HYD">HYD</html:option>
					 <html:option value="BANG">BANG</html:option>
					 </html:select>
					  
				</td>
					<td class="lbl" align="left">ID:
						<html:select name="DisplayForm" property="id">
							<html:option value="">--All--</html:option>	
							<html:option value="100">101</html:option>
							<html:option value="101">101</html:option>
							<html:option value="102">102</html:option>
						</html:select>
						  
					</td>
					
		</tr>
		<tr>
		 <td align="center">
			<input type="button"  value="Buuton1" onclick="action">
		</td>
		<td align="center">
			<input type="button"  value="Buuton2" onclick="action">
		</td>
		<td align="center">
			<input type="button"  value="Buuton3" onclick="action">
		</td>
          </tr>
	</table>
  </td>
</tr>
</table>
<!-- Displaying the below data after clicking 1st button-->
	<logic:equal name="DisplayForm" property="button1" value="true" >
	<logic:present name="DisplayForm" property="button1">
		<table width="100%" cellpadding="1" cellspacing="0" border="3">
		<tr align="center">
				<td>aaa</td>
				<td>bbb</td>
				<td>ccc</td>
				
		</tr>
		<tr>
				<td>3</td>
				<td>4</td>
				<td>5</td>

		<tr>

		</tr>
	</table>
	</logic:present>
	</logic:equal>
	</html:form>
