Regex replace(/\n/g，“”)不起作用。

I have this string 02/11/2015 \n € \n that I show into a popup. Before I do this I use a RegEx to replace \n with <br/>. But it doesn't work.

我有这个字符串02/11/2015 \ n€我显示为一个弹出\ n。在此之前，我使用RegEx替换\n与
。但它不工作。

Here is the code:

这是代码:

message= "02/11/2015 \n € \n";
message= message.replace(/\n/g, "<br />");

var popup = $('<div><span style="font-weight: bold; color: #1d5987;"> <p>'+ message+'</p> </span></div>');
$('document').append(popup);
popup.dialog({
    autoOpen : true,
    modal : true,
    resizable: false,
    width:'45%',
    height: 'auto',
    close: function(event, ui){ 
        $(this).dialog('destroy');
    }           
});

In the pop-up 02/11/2015 \n € \n appears again.

在弹出的02/11/2015 \n \n再次出现。

I use the chrome console to debug it, after replace function is executed in the message string there are no changes.

我使用chrome控制台调试它，替换函数在消息字符串中执行后没有变化。

You may have error in

你可能有错误。

$('document').append(popup);

The selector 'document' is nothing. Use $(document) without the quotes, or rather $('body') or append directly to some element by ID

选择器“文档”什么都不是。使用$(document)，不使用引号，或者$('body')，或者通过ID直接追加到某个元素。
