Kendo Data Grid Angular 升级 14 期

Question

我正在使用 Angular 的剑道网格。升级到 Angular 14 后，使用 package.json 中的以下包在 kendo 网格中加载数据时看到以下错误。如果这是软件包版本问题，请告诉我。

TypeError: Cannot read properties of undefined (reading 'add')
    at ListComponent.ngOnInit (index.js:11229:28)
    at callHook (core.mjs:2491:22)

Answer 1

错误：

TypeError: Cannot read properties of undefined (reading 'add') at ListComponent.ngOnInit (index.js:11229:28) ...

说明出了什么问题。只需转到

ListComponent

的

ngOnInit

方法并检查何时使用

add

（方法/属性）以及为什么它的“所有者”是

undefined

。升级后，某些流程或命名可能会发生变化并导致此类问题。
