I want swedish message when button clicked but it showing following.

Please help me how will I solve it?

Answer 1

function ConfirmGroupDelete() {
            var labelMsg = document.createElement("Label"); // create Label dynamically
            labelMsg.innerHTML = "Är du säker på att du vill ta bort alla händelser i gruppen Test3?";

            if (confirm(labelMsg.innerHTML)) {
                return true;
            } else {
                return false;
            }
}

Now I did like this way. I have found corresponding HTML code of swedish word and replace it into my message. Then I have created a label dynamically and set that message into the innerHTML property of the Label and then shown in the confirm box. If I direct put the message into confirm("") then it shows as normal text(&Amul is showing). I don't know what is the reason behind it, If anybody has good suggestion, you can tell me.
