Less：第二次调用@ font-face参数mixin保持第一次调用的值 [英] Less: second call of @font-face parametric mixin keeps values from first call

问题描述

我尝试在LESS中加入网页字体。参数mixin的部分工作如下：

I try to include web fonts with LESS. The parametric mixin which partly does the job is the following:

.fontface(@fontName, @fontFile) { 
    @font-face { 
        font-family: @fontName;
        src: url("@{fontFile}.eot");    
        src: url("@{fontFile}.eot?#iefix") format('embedded-opentype'),
        url("@{fontFile}.woff") format('woff'),
        url("@{fontFile}.ttf") format('truetype'),
        url("@{fontFile}.svg#DistantGalaxyRegular") format('svg');
        font-weight: normal;
        font-style: normal; } }
.font(@fontsize:10pt, @fontName:"Aierbazzi", @fontFile:"Aierbazzi-fontfacekit/aierbazzi-webfont") { 
        .fontface(@fontName, @fontFile);
font-family:@fontName;
font-size:@fontsize; }

它第一次调用时工作正常：

It works fine being called the first time:

.font1 { .font(24pt, "Black-Rose","Black-Rose-fontfacekit/BLACKR-webfont"); }
.font4 { .font(24pt, "bubblegum-sans","bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont"); }

导致：

.font1 { 
    font-family:"Black-Rose";
    font-size:24pt; }
    @font-face { 
        font-family:"Black-Rose";
        src:url("Black-Rose-fontfacekit/BLACKR-webfont.eot");
        src:url("Black-Rose-fontfacekit/BLACKR-webfont.eot?#iefix") format('embedded-opentype'),url("Black-Rose-fontfacekit/BLACKR-webfont.woff") format('woff'),url("Black-Rose-fontfacekit/BLACKR-webfont.ttf") format('truetype'),url("Black-Rose-fontfacekit/BLACKR-webfont.svg#DistantGalaxyRegular") format('svg');
        font-weight:normal;
        font-style:normal; }

.font4 { 
    font-family:"bubblegum-sans";
    font-size:24pt; }
    @font-face { 
        font-family:"Black-Rose";
        src:url("Black-Rose-fontfacekit/BLACKR-webfont.eot");
        src:url("Black-Rose-fontfacekit/BLACKR-webfont.eot?#iefix") format('embedded-opentype'),url("Black-Rose-fontfacekit/BLACKR-webfont.woff") format('woff'),url("Black-Rose-fontfacekit/BLACKR-webfont.ttf") format('truetype'),url("Black-Rose-fontfacekit/BLACKR-webfont.svg#DistantGalaxyRegular") format('svg');
        font-weight:normal;
        font-style:normal; }

当我交换两行时：

.font4 { .font(24pt, "bubblegum-sans","bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont"); }
.font1 { .font(24pt, "Black-Rose","Black-Rose-fontfacekit/BLACKR-webfont"); }

只是第一个网络字体在CSS中注册：

again just the first web font is registered in the CSS:

.font4 { 
    font-family:"bubblegum-sans";
    font-size:24pt; } 
@font-face { 
    font-family:"bubblegum-sans";
    src:url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.eot");
    src:url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.eot?#iefix") format('embedded-opentype'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.woff") format('woff'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.ttf") format('truetype'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.svg#DistantGalaxyRegular") format('svg');
    font-weight:normal;
    font-style:normal;}

.font1 { 
    font-family:"Black-Rose";
    font-size:24pt; }
@font-face { 
    font-family:"bubblegum-sans";
    src:url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.eot");
    src:url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.eot?#iefix") format('embedded-opentype'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.woff") format('woff'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.ttf") format('truetype'),url("bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont.svg#DistantGalaxyRegular") format('svg');
    font-weight:normal;
    font-style:normal; }

可能是什么原因？我现在无能为力。
提前非常感谢。

What could be the reason? I am clueless in the moment. Thank you very much in advance.

推荐答案

基于这个当前（作为我的回答）错误，我使用一个解决方案一个人张贴在那里修改您的代码。它创建需要输入 @fontName 的复制，以避免将变量传递到 .fontface call它现在从 @ font-face 块中调用），但它提供了正确的输出：

Based on this current (as of my answer) bug, I used a solution a person posted there to modify your code. It creates the need for a replication of entering the @fontName so that you avoid passing a variable into .fontface call (which is now called from inside the @font-face block), but it does give the proper output:

LESS

.fontface(@fontName:"Aierbazzi", @fontFile:"Aierbazzi-fontfacekit/aierbazzi-webfont")  {   
    font-family: @fontName;
    src: url("@{fontFile}.eot");    
    src: url("@{fontFile}.eot?#iefix") format('embedded-opentype'),
    url("@{fontFile}.woff") format('woff'),
    url("@{fontFile}.ttf") format('truetype'),
    url("@{fontFile}.svg#DistantGalaxyRegular") format('svg');
    font-weight: normal;
    font-style: normal; 
} 

.font(@fontsize:10pt, @fontName:"Aierbazzi"){
    font-family:@fontName;
    font-size:@fontsize; 
}

.font1 { 
    .font(24pt, "Black-Rose");
    @font-face { 
       .fontface("Black-Rose","Black-Rose-fontfacekit/BLACKR-webfont");
    } 
}

.font4 { 
    .font(24pt, "bubblegum-sans");
    @font-face { 
        .fontface("bubblegum-sans","bubblegum-sans-fontfacekit/BubblegumSans-Regular-webfont");
    } 
}

CSS输出 p>
