Hi Guys

javascript:loadStatesFirstUI(this.options[this.selectedIndex].value,<c:out value="${formName}

inside this if statement

<c:if test="${country.code eq USACountry}">
      selected="selected"
</c:if>

Would anyone please help me on this

---------------------------------
<select class="logon select" id="<c:out value="WC_AddressEntryForm_FormInput_${prefix}country_1"/>" name="<c:out value="${prefix}country"/>" onload="javascript:loadStatesFirstUI(this.options[this.selectedIndex].value,<c:out value="${formName}"/>, '<c:out value="${prefix}"/>')" >
                  <c:forEach var="country" items="${countryBean.countries}">
                   <c:out value"${country.code}" />
                        <option value="<c:out value="${country.code}"/>"
                              <c:if test="${country.code eq USACountry}">

                              </c:if>

teh usual way with a select is with the onChange event

onChange="someFunction()"
or
onChange="someFunction(somevalue)"

also selects don't have an onload event

<c:if test="${country.code eq USACountry}">
     selected="selected"

I suppose that you mean that the Javascript code should be run when the page loads in the browser, if any of the options was marked as selected.

The JSP code runs when the page is created on the server, so you can't call a Javascript directly from the JSP code. Also, if you output code that would call the Javascript in the condition, it would end up in the middle of the option tag.

If the condition is true, store the value of the option in a variabe, then after the </select> tag, you can check the value of the variable. If it has been set, you output a script tag that contains the Javascript call, and use the variable value as the first parameter in the call.
