这个错误表示 marketGoodsData 不是一个可迭代对象,或者它不具有 push 方法。请确保你在调用 push 方法之前,已经正确地声明和初始化了 marketGoodsData 变量。另外,你也可以确认一下 marketGoodsData 的类型是否正确,是否应该是一个数组对象。如果问题仍然存在,请提供更多的代码和上下文信息,这样才能更好地帮助你解决问题。

TypeError: actionArr.push is not a function
This error message indicates that the push method is being called on a variable that is not an array. The push method is used to add elements to the end of an array, but if it is called on a non-array variable, it will throw an error.
To resolve this error, you need to ensure that the variable you are calling push on is actually an array. You can use the typeof operator to check the type of the variable and make sure it is an array before calling push.
For example:
```
let actionArr = [];
if(typeof actionArr === "object" && actionArr instanceof Array) {
actionArr.push("new element");
}
```
In this example, we use the typeof operator to check that actionArr is an "object" and the instanceof operator to check that it is an instance of Array. If both conditions are true, we can safely call the push method on actionArr.
TypeError: that.getPageStudents is not a function
TypeError: that.getPageStudents is not a function 这个错误通常表示在代码中调用了一个不存在的函数。根据提供的引用内容,可以看出这个错误是因为在代码中使用了一个没有定义的函数getPageStudents。解决这个问题的方法是确保getPageStudents函数被正确定义和导入。根据引用中的正确代码,可以将res转换为一个数组,并使用forEach循环来执行相应的操作。请确保getPageStudents函数已经正确定义并且可以在代码中正常访问到。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
