是用来把一个json字符串里的key全都取出来重新整成一个数组的方法,那么这个函数怎么用呢,接下来贴出我最近碰见的用法: let groups={"key1":'value1',"key2":'value2',"key3":'value3',"key4":'value4',"key5":'value5'} Object.keys(groups)//[ 'key1', 'key2', 'key3
groups[group] = groups[group] || [],在js中对象也是关联数组,因此这里相当于做了两件事,一是把group作为groups的key,二是将对应的value初始化,第一次执行为空数组,循环执行时找到相同的name时保持不变; groups[group].push( o ),这句相当于把list中每个对象压入数组中作为value; 最后,Object.values(group...
