warning Attribute ':pageSizes' must be hyphenated vue/attribute-hyphenation
时间: 2024-03-03 13:48:34 浏览: 39
这个警告是因为 Vue.js 的属性绑定规则要求组件的属性名必须使用短横线命名法(kebab-case),而不是驼峰式命名法(camelCase)。
例如,如果你有一个组件的属性名为 pageSizes,应该改成 page-sizes。这样就不会出现这个警告了。
如果你不想修改属性名,也可以在组件的选项中添加一个 props 属性,用来指定这个属性的名称。例如:
```
Vue.component('my-component', {
props: {
pageSizes: {
type: Array,
default: function () {
return [10, 20, 30, 40]
}
}
}
})
```
这样就可以通过 this.pageSizes 访问到这个属性了,而且不会出现警告。

warning Attribute "v-model" should go before ":disabled" vue/attributes-order
这个警告是由 Vue.js 的 eslint 规则中的 `vue/attributes-order` 规引发的。它要求在 Vue 组件中按照特定的属性顺序编写代码。
根据这个警告,`v-model` 属性应该在 `:disabled` 属性之前编写。例如:
```html
<input v-model="myValue" :disabled="isDisabled">
```
请注意,这个警告是一个代码风格检查提示,旨在提高代码的可读性和一致性。按照规范编写代码可以让代码更易于维护,并与其他开发人员保持一致。
`slot` attributes are deprecated vue/no-deprecated-slot-attribute
This warning message is related to the use of the `slot` attribute in Vue.js. In Vue.js, slots are used to create reusable components that can be used across multiple parts of an application. However, the `slot` attribute has been deprecated in favor of a new syntax introduced in Vue.js 2.6.0.
The new syntax for slots involves using the `v-slot` directive, which provides a more explicit and flexible way of defining and passing data to slots. The `v-slot` directive can be used as a shorthand for the more verbose `slot-scope` syntax.
To fix this warning, you should update your code to use the `v-slot` directive instead of the deprecated `slot` attribute. Here's an example of how to update a slot component that uses the deprecated `slot` attribute to use the new `v-slot` directive:
```
<!-- Deprecated slot component -->
<my-component>
<div slot="header">Header content</div>
<div slot="body">Body content</div>
</my-component>
<!-- Updated slot component -->
<my-component>
<template v-slot:header>Header content</template>
<template v-slot:body>Body content</template>
</my-component>
```
Note that the `v-slot` directive can also be used with shorthand syntax, like this:
```
<my-component>
<template #header>Header content</template>
<template #body>Body content</template>
</my-component>
```
This shorthand syntax is equivalent to the previous example and can be used if you prefer a more concise syntax.
