Question

I have a iterator which goes through a list and create their name and for each of them a button. I want when the user click the button put the same name that has been clicked in the session
This is my code

        <s:iterator value="packageCities" status="portStatus">
            <tr>
                <td>
                    <s:property value="cityName" />
                </td>
            </tr>
            <s:if test="%{status == 0}">
                <tr>
                    <td>
                        <s:submit method="open"  align="center" value="" cssStyle="background: transparent url(image/open.png) no-repeat center top; border: 0px; width: 150px; height: 30px;" >
                            <s:set name="button" value="cityName" scope="session"/>
                        </s:submit>
                    </td>
                </tr>
            </s:if>
        </s:iterator>

But The problem is it only sets the last property , And it doesn’t set it when user clicked the button! so it like when its creating the button it is putting the cityName in the session! But I only want to put different thing in session by clicking different buttons!
Can Any Body Help?

Answer 1

There are two solutions:

1. Submit the value along with the form (a hidden field may be used for this purpose). Then set the session variable in the action class.
2. Make a synchronous ajax request to set the session value onclick of the submit buttons.

As Dave mentioned when the jsp is loaded the values are already set you cannot change them from client side.

EDIT

Ok, as you requested, here is a basic idea of the first method. The idea is to set the id of submit buttons with the respective cityName and then onclick of button call a javascript function to set a hidden field’s value with the clicked button’s id (i.e. its cityName)

<s:form>
<s:hidden id="value_to_submit" name="value_to_submit"/>
<s:iterator value="packageCities" status="portStatus"><s:form>
    ....
                <s:if test="%{status == 0}">
                    <tr>
                        <td>
                            <s:submit id="%{cityName}" onclick="set_hidden_value(this.id)" method="open"  align="center" value="" cssStyle="background: transparent url(image/open.png) no-repeat center top; border: 0px; width: 150px; height: 30px;" >
                            </s:submit>
                        </td>
                    </tr>
                </s:if>

    </s:iterator>
</s:form>

Javascript

function set_hidden_value(myvalue){
document.getElementById("value_to_submit").value=myvalue;
}

Now you can capture the value of the variable value_to_submit in your action class and set the session variable there.
