How to pass expression to .js file

Question

Hello Techies,
I am trying to an expression to java script function.
Here is my code
<script language="javascript">
    <!--
     document.write('<script type="text/javascript" language="javascript" src="<%=Context%>/htmls/js/Set.js">');
    //-->
    </script>
  onClick="JavaScript:doSubmit('<%= sss %>')"In set.js file I had written the code like the following
function doSubmit(requestType) {
       alert(document.xxxForm.<%=xyz%>.value);
          I had placed this set .js file in separate folder named as JS.
I had placed the .jsp files in one folder named as jsp.
How to call the doSubmit() in the set.js file from the jsp file.
Thanks,
Krishna

What i am trying is I am having a combo box in which any item is selected and clicked add button the request must send to the server else we will get one alert msg that "Plz check the evalution".
<script language="javascript">
    <!--
     document.write('<script type="text/javascript" language="javascript" src="<%=Context%>/htmls/js/set.js">');
    //-->
    </script>
   some code
<input
                        type="button"
                        name="submitButton"
                        value="Save"
                        onClick="JavaScript:doSubmit('<%= Request.add %>')"
                    />The set.js file is
var current = location.toString();
var noProtocol = current.split('//')[1];
var context = noProtocol.split('/')[1];
function doSubmit(requestType) {
  alter("inside doSubmit");
var evalutionValue =   document.setForm.<%=request.EVALUATION%>.value;
      if( evalutionValue == '' || evalutionValue == null)
            alert("plz select the Evalution ");
            return false;
     document.forms["setForm"].elements["<%= request.REQUEST_TYPE %>"].value = requestType;
            document.forms["ruleSetForm"].submit();
        }How can I do this one
