I have the following code that represents a company office hours. I am trying to understand the array of var sunday_hours = new Array(). When I try to change the variables in the array it doesn't seem to update the office hours on the display. Can anyone help me understand this?


PHP Code:
    function validateresult() {
        
jQuery.post(''
        
jQuery("#appointmentid").serialize(),
        function(
responseText) {
            
document.getElementById("formstatus").innerHTML=responseText;
            if(
responseText.search('success')>-1){
                
document.appointmentform.reset();
            }
        });
    }
    
    var 
sunday_hours = new Array(
        
'10',
        
'20',
        
'',
        
'',
        
'on',
        
'12'
    
);

    var 
monday_hours = new Array(
        
'11',
        
'20',
        
'15',
        
'',
        
'',
        
'12'
    
);

    var 
tuesday_hours = new Array(
