将请求参数从操作方法发送到jsp

Question

I have a form with a drop down list in a JSP page

<html:form action="/accountProcess">
        <html:hidden property="dispatch" value="getUsers" />
          <select name="user_status_filter" onchange="this.form.submit()">
            <option value="Status">Status</option>
            <option value="all" >All</option>
            <option value="inactive">Inactive</option>
            <option value="active">Active</option>
          </select>
</html:form>

in my action method I'm doing the following:

String requestValue = RequestUtils.getStringParameter(request, "user_status_filter");

and it's working great, but I also want to send back the same exact string so that I can add the "selected" string to the right option element to keep it selected when the form is submitted.

right now I'm doing this in my action method

request.setAttribute("selectedValue", requestValue);

but I don't know how to add conditional logic to my jsp so that it's something like

if (${selectedValue}.equals("all")
<option value="all" selected>All</option>

Answer 1

Try this

<option value="all" ${selectedValue == 'all' ? 'selected' : ''}>All</option>

Just change the value you compare it to in every <option> .
