有没有办法在LESS中使用正则表达式?这是我的代码:
的CSS:
@color: red;
body{color:@color;}/*Text is red if LESS is loaded correctly */
span{display:inline-block;position:relative;top:2px;}
.char1{.titel-animation(0s);}
.char2{.titel-animation(0.2s);}
.char3{.titel-animation(0.4s);}
.char4{.titel-animation(0.6s);}
.char5{.titel-animation(0.8s);}
.char6{.titel-animation(1s);}
.titel-animation(@delay){
animation: sitetitel 1s @delay ease 1;
-moz-animation: sitetitel 1s @delay ease 1;
-webkit-animation: sitetitel 1s @delay ease 1;
}
@keyframes sitetitel {
50%{
color:blue;
}
}
@-moz-keyframes sitetitel {
50%{
color:blue;
}
}
@-webkit-keyframes sitetitel {
50%{
color:blue;
}
}
HTML:
<span class="char1">F</span>
<span class="char2">o</span>
<span class="char3">o</span>
<span class="char4">b</span>
<span class="char5">a</span>
<span class="char6">r</span>

我想要的是替换
.char1{.titel-animation(0s);}
.char2{.titel-animation(0.2s);}
.char3{.titel-animation(0.4s);}
.char4{.titel-animation(0.6s);}
.char5{.titel-animation(0.8s);}
.char6{.titel-animation(1s);}
通过这样的方式:
.char@number{.titel-animation(((@number-1) *0.2)s);}
如果可能的话
答案 0 :(得分:2)
不是正则表达式,但您可以使用警卫来获取递归。我认为以下是你所要求的......
.charX(@number) when (@number > 0) {
(~".char@{number}") {
@adjustedNumber: (@number - 1) *0.2;
@unitNumber: ~"@{adjustedNumber}s";
.titel-animation(@unitNumber)
}
.charX(@number - 1);
}
.charX(@number) when (@number = 0) {
}
.charX(6);
