如果值正确，将无法显示警告

Question

I am trying to get the following form submission to show alert box if value is not equal to 'Province"

 function validate_form ( )
    {

    if ( document.contactForm.Province!='Region 1' )

    alert ( "Please Note: We only install in Region 1!" );

    }

My form name is "contactForm" my select menu is called "Province" I always get the alert here regardless of the selection in Province.

What am I doing wrong?

Answer 1

您需要将其与该元素的值进行比较：

 if ( document.contactForm.Province.value != 'Region 1' )

Answer 2

Try this

function validate_form ( )
{
    var temp = document.getElementbyId(Province);
    var strUser = temp.options[e.selectedIndex].text;
    if (strUser != 'Region 1' )
        alert ( "Please Note: We only install in Region 1!" );
}
