js中的数组筛选fliter

有一个需求是在前端部分完成筛选功能,一次拿到所有数据,然后根据条件筛选。通常情况下筛选是后台给接口,在数据量不大的情况下,也有人可能会遇到前端筛选这样的情况。
一般情况下的单条件筛选,数组的filter方法就能够满足需求,本文讨论的重点是多条件下的复合筛选,并列出了几个相关知识点。
filter()创建一个新的数组,新数组中的元素是通过检查指定数组中符合条件的所有元素。
array.filter(function(currentValue,index,arr), thisValue);
filter() 方法用于把Array中的某些元素过滤掉,然后返回剩下的未被过滤掉的元素。
filter() 不会对空数组进行检测;
filter() 不会改变原始数组。
单条件单数据筛选
根据单个名字筛选,用filter方法,判断name是否为目标名字即可
// 根据单个名字筛选
