angularjs：动态键：值对作为函数的参数

Question

I have a key value pair which is dynamic.

myObj = { 
    category1: ["a","b","c"], 
    category2: ["a","d","e"],
    category3: ["a","f","g"],
    ...
    ..
    .
}

I need to get intersection value as "a". For that I'm using underscore js's _.intersection() function

Depending on dynamic categories, I need to pass dynamic arguments to _.intersection()

like

_.intersection(myObj[category1], myObj[category2], ..., ..., myObj[categoryN]);

Answer 1

尝试：

_.intersection.apply(_, Object.values(myObj));
