Bad practice to evaluate data in underscore.js micro template?

Question

Are there any consequences of evaluating data in underscore micro templates?

for instance if we say we have this in our javascript file:

this.template({a: '10'});

And in our html template file

<%= a > 5 ? 'Val is larger than 5':'Val is smaller than 5' %>

Would it be better not to evaluate the data in the template?

不是分离问题吗？你在一个表达的“层”中注入逻辑，在我看来，潜在的错误将更难以跟踪。

您的示例很简单，但想象一下您有类似

的情况

<%= a > 10 ? (b > 20 ? " and b greater than 20" : " and b less than 20") : ( c > 20 ? " and c greater than 20" : " and c less than 20") %>
