RactiveJS: How to sort table by computed value?

Question

I'm new to ractive and looking at the table sort tutorial at https://ractive.js.org/tutorials/iterative-sections/#step-5

But what if I want to sort by a "computed" value, such as the output of:

{{#resources}}
    {{#if (type_id==1) }}
        {{name}}
    {{elseif parent_id!=15173}}
        {{name}}
    {{/if}}
{{/resources}}

or:

{{client.0.name}}

?

你可以通过使用带有compare函数参数的sort（）来实现这一点 - 例如，array.sort（function（a，b）{/ *为a和b生成计算值（基于你的模板逻辑）并返回比较结果新的价值}）;
