Use the .html()method instead of .text().

使用.html()方法而不是.text()。

The whole point of .text()method is to make the text appear exactly as it's in the string, with all tags and entities.

整点.text()的方法是使文本显示，正是因为它是在字符串中，所有的标签和实体。

If you use a unicode escape ('\u25B2') instead of the html escape character, you can use the .text method.

如果您使用 unicode 转义符 ('\u25B2') 而不是 html 转义符，则可以使用 .text 方法。

Some users will not have a font that will display either version.

某些用户将没有可显示任一版本的字体。

..or if someone wants to use just javascript:

..或者如果有人只想使用javascript：

var d = document.createElement("div");
d.appendChild(document.createTextNode("500"));
var euro = document.createElement("span");
euro.innerHTML = "€"; //your character
d.appendChild(euro);

prints: 500

印数：500

&#x25B4is definitely notascii (ascii's a character code that runs from 0 to 127...!-) -- it seems to be a high-page unicode character. What char encoding is your page using? With something "universal" like utf-8, unicode characters shouldshow up... if the browser has them in its font, of course. With other encodings, such characters might just be impossible to transmit and show.

&#x25B4绝对不是ascii（ascii 是从 0 到 127 的字符代码......！-）——它似乎是一个高页 unicode 字符。您的页面使用什么字符编码？对于像 utf-8 这样的“通用”字符，unicode 字符应该显示出来……当然，如果浏览器的字体中有它们。使用其他编码，此类字符可能无法传输和显示。
