compare two values in jquery i cannot get "Hi" alert

Question

how i can compare two values json return true in is delivered property and i want to compare it with string

$.getJSON('/SalesInvoice/GetSI/' + $('#SearchSI').val(), function (data) {

     if (data.ex == "OK") {
         if(data.Voucher.IsDelivered == "true")
         {

             alert('hi');
         };
}

Uh, so the comparison failed, maybe you should log the values and figure out what they are then ? — adeneo, Jul 02 '14 at 15:58
What's data? What does GetSI do? this does not contain the bear minimum of information to answer this question — Liam, Jul 02 '14 at 15:59

If in the JSON, the value is true and you want to check it using "true" it would result in false.

I think you should convert the string to a simple bool true.

if(data.Voucher.IsDelivered == true)
{
   alert('hi');
};

Or a simpler one

if(data.Voucher.IsDelivered)
{
   alert('hi');
};

Because if you see, the (bool == string) = false. Always check the data types while using a conditional statement.

Why dont you add an else to the IF statement so that you can see exactly what is in the variable in question. Like this:

 if (data.ex == "OK") {
     if(data.Voucher.IsDelivered == "true")
     {

         alert('hi');
     } else {
         alert( data.Voucher.IsDelivered + ' = ' + typeof data.Voucher.IsDelivered )
     }
