Attributes
[属性]
Most of the functions take attributes that specify or modify their behavior. Attributes to Smarty functions are much like HTML attributes. Static values don't have to be enclosed in quotes, but it is recommended for literal strings. Variables may also be used, and should not be in quotes.
大多数函数都带有自己的属性以便于明确说明或者修改他们的行为.
smarty函数的属性很像HTML中的属性.
静态数值不需要加引号,但是字符串建议使用引号.
如果用变量作属性,它们也不能加引号.
Some attributes require boolean values (true or false). These can be specified as either unquoted true, on, and yes, or false, off, and no.
一些属性用到了布尔值(真或假).
它们不需要加引号,可以是true,on,yes或者false,off,no.
