I have a select tag which populates all the countries. What I need is that when United states is selected it executes a javascript which basically populates the states drop down.

I tried putting the code to call teh javascript inside an if statement which is inside of select tags but somehow it puts teh javascript code as one of the values in dropdown. Would you guys know if I am doing something wrong. Also if this is not possible is there a way I can check outside the select tags if United states is selected, if it is than execute the javascript code.

Any help weill be greatly appreciated

<select class="logon select" id="<c:out value="WC_AddressEntryForm_FormInput_${prefix}country_1"/>" name="<c:out value="${prefix}country"/>" onchange="javascript:loadStatesUI(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}">
                                    selected="selected"
                                    <Script>
                                    loadStatesFirstUI(this.options[this.selectedIndex].value,<c:out value="${formName}"/>, '<c:out value="${prefix}"/>')
                                    </Script>
                              </c:if>
                              <c:if test="${country.code eq paramSource.country || country.displayName eq paramSource.country}">
                                    selected="selected"
                              </c:if>
                        ><c:out value="${country.displayName}"/></option>
                  </c:forEach>
            </select>

Options never fire events, you need to put the event on the select. Have the select function check the selected option to see id it is the united states, and if it is have it preload, otherwise do nothing.


so maybe something like this..


<select onchange="loadStatesUI(this)">


function loadStatesUI(obj)
{
if(obj.options[obj.options.selectedIndex].value =="United States")
{
//pre load states
}
}
