VM2096:2 Uncaught TypeError: input.select is not a function at <anonymous>:2:7

This error is usually caused when trying to use the `.select()` method on an element that does not support it. It is possible that the `input` variable is not referencing an input element, or that the element is not yet available when the code is run.

To resolve this issue, make sure that `input` is referencing an input element and that the element is available before attempting to use the `.select()` method. You can also use the `console.log()` method to check the value of `input` and make sure it is what you expect it to be.

报错：VM3870:1 Uncaught TypeError: document.getelementsbytagname is not a function at <anonymous>:1:10，怎么解决

这个错误是因为你使用了小写的方法名 `getelementsbytagname`，而正确的方法名应该是 `getElementsByTagName`（注意大小写）。请将方法名中的 `b` 改为大写即可解决问题。修改后的代码如下：

document.getElementsByTagName('tagName');

index.vue:730 Uncaught TypeError: (totalCount.value.energySave + 0.12).toFixed is not a function at index.vue:730:1 9 index.vue:730 Uncaught TypeError: (totalCount.value.energySave + 0.12).toFixed is not a function at index.vue:730:1

这个错误表示在 `index.vue` 文件的第730行出现了一个类型错误。具体错误是 `(totalCount.value.energySave + 0.12).toFixed is not a function`，意思是 `toFixed` 不是一个函数。

`toFixed` 是 JavaScript 的内置函数，用于将数字四舍五入为指定小数位数的字符串。根据错误信息，`totalCount.value.energySave + 0.12` 的结果应该是一个数字，但它似乎不具备 `toFixed` 方法。

可能的原因是 `totalCount.value.energySave` 的类型不正确，它可能不是一个数字。你可以检查一下 `totalCount.value.energySave` 的值和类型，确保它是一个数字，然后再使用 `toFixed` 方法进行四舍五入操作。
