Alerting Special Characters using jQuery/JavaScript

问题

How do i display a string with Special Characters like € in a Javascript/jQuery alert?

eg: I want to display a message box with "The Price is €10"

But when i use the below code:

alert("The Price is &euro;10");

The Output shown in the message box is "The Price is €10", I want my output to be "The Price is €10".

Can some help me with this please? Thanks in advance.

Use this as the alert. Works fine for me.

alert(' The Price is \u20AC 10');

The native alert method does not decode HTML encoded entities.

But browsers do while rendering HTML. One hack is to create a HTML element with the specific text as its innerHTML (so it does the character processing), then get back its text property and alerting it out.

function alertSpecial(msg) {
    msg = $('<span/>').html(msg).text();
    alert(msg);
}
alertSpecial('The Price is &euro;10');

This will work for all &xxx characters that the browser can display, without needing to find out the character code for each special character you may want to use.
