问题描述

我有这个片段的SASS代码：

       只是连接字符串？
 
 
   src：url（'fonts / myfont'+ $ rndnum +'。svg'）;  
 
 
 你有代码为 $ rndnum 被设置为因为这也可能是一个问题以及如何设置该变量。 
 
 
 编辑1：
 
 
 你只需要 src 行后面的分号？ 
 
 
 您使用什么版本的sass？ 
 
 
 我尝试，它似乎工作完美在Sass版本3.3.3，但不是在版本3.2.15（在该网站提供的两个版本）。 
 
I have this fragment of SASS code:
@font-face {
  $rndnum: random(1000);
  font-family: myfont;
  src:url('fonts/myfont#{$rndnum}.svg')
  font-weight: bold;
  font-style: normal;
}
I need to put a random number after the name of the font, I know it seems stupid operation, but I need it. However the problem is that I get the following result:
@font-face {
  font-family: myfont;
  src:url('fonts/myfontrandom(1000).svg') /* <== HERE */
  font-weight: bold;
  font-style: normal;
}
The function does not get called for some reason...Where am I doing wrong?
Something more...
I tried calling another function like percentage:
@font-face {
  $rndnum: percentage(0.2);
  ...
And it worked in that case... looks like it is not recognizing random as a valid function...
 解决方案 
Have you tried just concatenating the string?
src:url('fonts/myfont'+$rndnum+'.svg');
And do you have the code for what $rndnum is being set as since this could also be a problem with how that variable is set. 
Edit 1:
Your code works for me.  Do you just need the semi-colon after the src line?  
What version of sass are you using? 
I tried it here and it seemed to work perfectly fine on Sass version 3.3.3 but not on version 3.2.15 (the two versions offered on that site).
