去除对象中的原始值属性、引用值属性值为空的属性——函数封装

在工作中，在调取接口时，经常需要往后端传递数据，如果后端那边没有对数据进行处理的话，则会因为一些空的数据导致接口调取失败。。

var obj = { "supplierId":0,"distributionChannel":null,"channelCount":0,"capacities":[{ "brandId":null,"leadTime":null,"payCondition":null}],"customers":[{ "name":null,"type":null,"brandName":null,"cooperationTime":null,"usedOfYear":null,"amount":null}],"productionDevices":[{ "name":null,"count":null}],"testingDevices":[{ "name":null,"count":null}],"artisanDevices":[{ "name":null,"count":null}],"honors":[{ "name":null,"year":2020,"picture":null,"issuingAuthority":null}],"staffs":[{ "name":null,"post":null,"characteristic":null,"background":null}],"talks":[{ "talkObject":null,"place":null,"organization":null,"companyPlanning":null,"productPlanning":null,"advantage":null,"shortcoming":null,"cooperation":null,"cooperationReason":null,"score":null,"scoreReason":null,"summary":null,"interviewer":null}]}

格式化一下，对象的结构如下：

注意这个对象中，有原始值也有数组格式的引用值，数据中的每一项又是对象格式的引用值。。

要把上面的对象将属性值为`null`的属性去掉的话，就需要循环遍历，去除`null`和`""`空字符串的函数封装如下：

控制台演示效果如下：
