Getting drop down value in JSP as request scope.

[amarshi mohanty]

Hi,

In my jsp , i have a drop down box , which on select i am submitting the page.After submitting the page , i am dispalying the same page with the output based on the slectected value from the drop down box.
But after the page submitted the , selectd value from the drop down box is not shown , rather the first value in the drop down box is displayed by default.
So when i am submitting the page , i am putting the selected value in request scope .
Then in the jsp , i am using the below code in selected options as:

   

<option value="5" selected =<% request.getAttribute("docsPerPage") == "5" ? "selected" : ""; %> >5</option>

but it not working.
what will be correct code?

Try this:

<option value="5" selected =<%= (request.getAttribute("docsPerPage") == 5) ? "selected" : "" %> >5</option>

This shows 5 as always selected.

You have to play around.
Try,

<option value="5" <%= (request.getAttribute("docsPerPage") == 5) ? "selected" : "" %> >5</option>

Also, whether to use "5" or 5, depends upon the type of "docsPerPage".

Did you look up the format for the <option> tag in HTML? You're not formatting it correctly.
For example, here's one description of the <option> tag: http://www.quackit.com/html/tags/html_option_tag.cfm
Then, look at the source of the response sent to your browser. Does it look right? If not, you should know how to correct the JSP now.
