添加新参数后发生错误

Question

我的测试用例运行正常，但在我的方法tiger中添加了额外的参数swiming之后，它就崩溃了。

我甚至将新参数tiger传递给我的测试用例，但它仍在破坏。

更新 我在这一行得到网格未定义...现在任何想法如何继续让grid = $（'＃henTigerGrid'）。data（'kendoGrid'）;

let tiger = {
    "nail": "hens/v1/sky/88888888888888",
    "columns": [],
    "title": "DOCUMENTS",
    "excelFileName": "ViewAiringsExport",
    "mainId": 88888888888888
};

代码如下：

嘿，我发现如果我删除此行错误正在修复

                "skyId": this._dataSource._data.length + 1,

Answer 2

在您的函数中，您对名称为AND posts.post_type LIKE 'product%' 的元素使用jQuery查找$('#henTigerGrid').data('kendoGrid');，该元素未在提供的单元测试中定义。在下面的几行中，您尝试访问查找的属性#henTigerGrid，然后失败。

这是错误使用服务定位器模式的典型示例（jQuery查找基本上是这样）。它们引入了隐藏的，无类型的依赖关系，这些依赖关系稍后会引起你的注意（请参阅当前的问如果要使用更多依赖项注入样式，则属性值（或Dom元素本身）将作为依赖项（此处为声明的参数）传递给函数。就像那样，错误甚至可能首先发生，因为你不会错过一个缺失的参数。
