用javascript编写html unicode符号

Question

How do you write html code in javascript?

I want to write:

document.title = "Title " + (▴); 

where the html code is in parentheses.

Answer 1

Don't do it with the parentheses; that's invalid syntax. Just put it in your string and use the JavaScript Unicode syntax \? :

document.title = "Title \u9652";

Here's a fiddle (note that jsFiddle won't let me change the title, so I change a div's contents instead).
