[英]Inline conditional statement using haml css
How do you write inline if else in haml/css? 您如何在haml / css中编写内联代码? Here is my working code:
这是我的工作代码:
- if unit > 10
= value
- else
.unit
= value
I tried to make it inline like the below, but that doesnt work: 我试图像下面这样使其内联,但这不起作用:
%span{class: ('my-value') if unit > 10})
首先评估括号,因此当单位大于10时,将把“我的值”设置为类别。
%span{class: ('my-value' if unit > 10)}
For simple cases like this I prefer the ternary operator: 对于像这样的简单情况,我更喜欢三元运算符:
%span{class: unit > 10 ? 'my-value' : nil}
If it gets any more complicated than a simple condition I would extract it to a helper: 如果它比简单的条件复杂,我可以将其提取给一个助手:
%span{class: unit_class(unit)}
And then in your helper file: 然后在您的帮助文件中:
def unit_class(unit)
if unit > 10
'my-value'
else
'something-else'
end
end
