hello：
我碰到了一个这样的问题，下路刷新的时候进行数据比对，如果有变化则调用this.setData({}),真不知道是哪里写错了，还是无法调用，
在ajax成功回调里面调用这个
new appUtil.ObjectCpm(app.GO.page_data, res.data, this).resultOp() |
util工具类中是这样的
class ObjectCpm { constructor(obj1, obj2, pages) { this.result = []; this.item = ""; this.obj1 = obj1; this.obj2 = obj2; this.pages = pages; (function () { try { if (Object.prototype.toString.call(obj1) != '[object Object]') throw new Error('第一的参数必须是对象') if (Object.prototype.toString.call(obj2) != '[object Object]') throw new Error('第二的参数必须是对象') if (Object.prototype.toString.call(pages.onHide) != '[object Function]') throw '必须把page传入' } catch (err) { throw err } console.log(obj1) console.log(obj2) })() } // 比较类 compary() { let result = this.result let item = this.item let obj1 = this.obj1 let obj2 = this.obj2 for (let i in obj1) { switch (Object.prototype.toString.call(obj1[i])) { case "[object Number]": item = obj1[i] != obj2[i] && i result.push(item) break; case "[object String]": item = obj1[i] != obj2[i] && i result.push(item) break; case "[object Boolean]": item = obj1[i] != obj2[i] && i result.push(item) break; case "[object Object]": let objectChange = true let resluts = ObjectCpm(obj1[i], obj2[i]) for (let j in resluts) { if (resluts[j] != false) { objectChange = false } } item = !objectChange && i result.push(item) break; case "[object Array]": let items = obj1[i], objectChanges = true if (obj1[i].length != obj2[i].length) { item = i } else { for (let z in obj1[i]) { if (Object.prototype.toString.call(obj1[i][z]) == "[object Object]") { let resluts = ObjectCpm(obj1[i][z], obj2[i][z]) for (let m in resluts) { if (resluts[m] != false) { objectChanges = false } } item = !objectChanges && i } else { item = obj1[i][z] != obj2[i][z] && i } } } result.push(item) break; } } return result } //结果类 resultOp() { let page = this.pages let resluts = this.compary() let obj2 = this.obj2 for (let i = 0; i < resluts.length; i++) { if (resluts[i] != false) { page.setData({ [resluts[i]]: obj2[resluts[i]] }) } } }} |
但是使用时出现
请问如何正确调用?
