Use this as the alert. Works fine for me.
将此用作警报。对我来说很好用。

The native alertmethod does not decode HTML encoded entities.
本机alert方法不解码 HTML 编码的实体。
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 textproperty and alerting it out.
但是浏览器在渲染 HTML 时会这样做。一种技巧是创建一个带有特定文本的 HTML 元素innerHTML（因此它进行字符处理），然后取回它的text属性并警告它。
function alertSpecial(msg) {
msg = $('<span/>').html(msg).text();
alert(msg);
}
alertSpecial('The Price is €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.
这将适用于浏览器可以显示的所有 &xxx 字符，而无需找出您可能想要使用的每个特殊字符的字符代码。
