VueJS自动继承Non-Prop Attributes,它非常适合data- *属性。
但我们不想继承“阶级”和“style”属性可以保护我们的核心组件免受任何新开发人员的任何布局更改。(因为我们希望所有组件的样式都在其样式文件中)
<template>
<div ref="root" class="hello">Hi</div>
</template>
<script>
export default {
mounted() {
this.$refs.root.className = 'hello'
}
}
</script>
要避免“非道具属性”继承,但是:
注意:此选项不会影响类和样式绑定。
https://vuejs.org/v2/api/#inheritAttrs
所以建议避免“课堂”和核心组件中的“样式”继承?

建议的解决方案:
Vue.component('my-feedback', {
props: ['type'],
data: function(){
var vm = this;
return {
classes: {
'my-feedback-info': vm.type === 'info',
'my-feedback-note': vm.type === 'note',
'my-feedback-warning': vm.type === 'warning',
'my-feedback-success': vm.type === 'success'
}
};
},
template: `
<div class="my-feedback" :class="classes">
<slot></slot>
</div>
`
});
但是,当依赖于组件的属性时,建议的解决方案甚至会变得复杂:
Sub CopyYesInW()
Dim lastRow As Long, i As Long
'determine last row in column W
lastRow = Cells(Rows.Count, "W").End(xlUp).Row
For i = 1 To lastRow
'if Yes in W then copy from P to W in current row
If Cells(i, "W").Value = "Yes" Then
Cells(i, "P").Value = Cells(i, "P").Value
End If
If Cells(i, "W").Value = "Yes" Then
Cells(i, "U").Value = Cells(i, "U").Value
End If
Next
End Sub

非常hacky的解决方案,但这对我有用
data(){
return {staticClass: ''}
},
mounted(){
// Capture the classes and use them on nested elements where desired
this.staticClass = this.$el.classList.toString()
// Remove the classes from the root element
this.$el.setAttribute('class', '')
}

您不能选择退出此行为,除非它是一个功能组件。
