算法查询

1、字符串是否包含某个字符
2、数组是否包含某个字符
3、对象中是否包含某个字符
4、数组中有多个对象，查找对象中的对象是否包含某个字符
5、数组中有多个对象，查找对象中是否包含某个字符

最后，代码如下：

const app = getApp()Page({data: {/******一、数组********* */arr: [123, {id: 2,value: '测试'}, '结果'],/******二、对象********* */object1: {id: 1,value: '柳州',code: 4545,obj: {id: 2,value: '桂林',code: 4544,},obj1:
