hi

i have a group of check boxes on a form for the user to select their residential status.

they have six choices and if they choose homeowner (the value of this field is o) they have to enter the value of property and amount of mortgage.

heres my code

if (theForm.m_res_status.value == “O”)

then

if ((theForm.m_value_of_prop.value ==””) ||
(theForm.m_amount_of_mortgage.value ==””))
{

alert(“Please enter the value of your property and the amount of mortgage”)
theForm.m_value_of_prop.focus()
return false;

}

i have also tryed

if (theForm.m_res_status(0).checked == true)
then

if ((theForm.m_value_of_prop.value ==””) ||
(theForm.m_amount_of_mortgage.value ==””))
{

alert(“Please enter the value of your property and the amount of mortgage”)
theForm.m_value_of_prop.focus()
return false;

}

but both of them make the value of property and amount of mortgage mandatory even if an option other than homeowner is selected ?

thanks for any help

cheers ThisAndThat

@ThisAndThatauthorApr 05.2004 — i seem to have got it to work using

if ((theForm.m_res_status(0).checked == false) ||

(theForm.m_res_status(1).checked == true) ||

(theForm.m_res_status(2).checked == true) ||

(theForm.m_res_status(3).checked == true) ||

(theForm.m_res_status(4).checked == true) ||

(theForm.m_res_status(5).checked == true))

then

if ((theForm.m_value_of_prop.value =="") ||
(theForm.m_amount_of_mortgage.value ==""))
{

alert("Please enter the value of your property and the amount of mortgage")
theForm.m_value_of_prop.focus()
return false;

}

if anyone has a better way that you can do this please feel free to let me know.

thanks ThisAndThat

@steelersfan88Apr 05.2004 — I've always enclosed them in brackets instead, but if not, you could generate that condition, such as:[code=php]var finStr = new String;
for(var i=0;i<6;i++) {
finStr += (i==0)?"(!theForm.m_res_status(0).checked":"theForm.m_res_status("+ i +").checked"
finStr += (i<5)?") || (":")"
}[/code]Then check the condition with:if(eval(finStr))which is much shorter than your current condition ?
