getting values from drop down menu

Expand Post »
HI,

I wish to get the values from the drop down menu selected by a user from the HTML page and pass this value into my servlet program for processing.

In my servlet program, I've used the getParameter() function to obtain the value from the drop down menu selected.


<SELECT name=Day>
<OPTION value="" selected>- Select -</OPTION>
<OPTION value=Sunday>Sunday</OPTION>
<OPTION value=Monday>Monday</OPTION>
<OPTION value=Tuesday>Tuesday</OPTION>
<OPTION value=Wednesday>Wednesday</OPTION>
<OPTION value=Thursday>Thursday</OPTION>
<OPTION value=Friday>Friday</OPTION>
<OPTION value=Saturday>Saturday</OPTION>
</SELECT>


String days= request.getParameter("Day");
System.out.println("DAY =" +days);

However, the value of the parameter "day" seems empty. May I know what is the correct method of getting the value selected from the drop down menu into my servlet? It did work when I use Javascript functions to extract it though (function getDay() in frmLockOut.html).

Attached are my JSP(frmLockOut.html) and Servlet(AdmProfileLockOut.java- see function add( ) ) source code files for reference.

Thanks
Danny

Re: getting values from drop down menu

Don't attach things, I won't open them.

Most likely you didn't place the select inside an html form which would cause the value to not be passed in the request.

Re: getting values from drop down menu

Wrong way to ask a question. We're not here to do your bidding at your whim. Maybe you should have started researching sooner if you're in a hurry now.

the multiselect is not possible with a dropdown, only with a selectbox.

You can get the values with getParameterValues(String) on the ServletRequest.
The API docs will give you more information.

Re: getting values from drop down menu

You should be creating a new topic for a new question. You also might want to be asking this question in the JavaScript forum.

Re: getting values from drop down menu

lets say I have a select box like
JSP Syntax (Toggle Plain Text)
  1. <SELECT id="MySelect" multiple >
  2.   <option value="A">Text 1<option>
  3.   <option value="B">Text 2<option>
  4.   <option value="C">Text 3<option>
  5. </SELECT>

ok now if I want to get all the selected values of this multiple select box I just call :-

JSP Syntax (Toggle Plain Text)
  1. String[] arrValues[] = objRequest.getParameterValues("MySelect");

but now my problem is how do I get the text values.

I know in JavaScript I can get both the text and the values by just issuing :-

JSP Syntax (Toggle Plain Text)
  1. document.getElementById("MySelect").value;
  2. document.getElementById("MySelect").text;

but how do I do this in Servlet, how do I do this in J2EE programmming ? :!:

How do I get the selected text value ?
