How to send selected value from jsp page to action class?

Question

I have this code in jsp page:

<select id="DateReport" style="width: 150px;">
        <option value="1"> 1 </option>
        <option value="2"> 2 </option>
        <option value="3"> 3 </option>
</select>

How do I send the selected value to action class in Struts 1.2?

Answer 1

You need a property in your form MyForm declared in your struts-config.xml file:

<form-bean name="myForm" type="foo.MyForm" />
[...]

and associate it with your action

<action path="/myAction" name="myForm" type="foo.MyAction" scope="request">

In your form:

public class MyForm extends ActionForm { 
    private String myValue; 
    [....] 

    // Getters and setters for all attributes 
}

Then in your JSP:

<html:form action="/myAction.do" method="post" >
    [...]

    <html:select styleId="DateReport" property='myValue' style="width: 150px;">
        <html:option value="1"> 1 </html:option>
        <html:option value="2"> 2 </html:option>
        <html:option value="3"> 3 </html:option>
    </html:select>

    [...]
</html:form>

In your action's execute(), you could get the value:

MyForm myForm = (MyForm) form; 
String value = myForm.getMyValue();
