Question
Javascript and checkboxes - problem when there are only one!
I am using a javascript that is controlling if the checkboxes are selected or not. This is done with the script below. There are always different number of checkboxes. The data is dynamic (mysql). Somtimes there are 10, sometimes 5 and somtimes only one checkbox. The script below does not work if there are only one checkbox in the list :( Anyone have a solution?
function checkBoxes() {
var box = document.frmBasis.elements
for( i = 0; i < box.length; i++ )
if( box[i].checked == true )
return true;
alert("Select one or more checkboxes!")
return false;
}
