使用-ms-filter转义LESS的语法：“codeNeedsVar”;

Question

我需要能够将变量变为

/* Opacity */
.opacity(@opacity: 0.35){
    -moz-opacity: @opacity;
    -khtml-opacity: @opacity;
    -webkit-opacity: @opacity;
    opacity: @opacity;
    @ieOpacity: @opacity * 100;
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=@ieOpacity)";
    filter: ~"alpha(opacity=@ieOpacity)";
}

如果符合此规则，代码在.css文件(Opacity=@ieOpacity)

中将如下所示

Answer 1

答案很简单，添加@{var}以便少知道它的变量而不是文本

-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=@{ieOpacity})";
