如何更改内部属性
How to change an inside attributes
我想做一个 header 按钮类型,例如:
如果我调用“HeaderFunction”,那么所有选择都将为假,只有我点击的一个为真。
并观察选定的属性 than=> 如果选定的属性为 true than :class 将被“选中”,所有其他选定的 false 属性将被“未选中”class...
我该如何处理?
<template>
<button
type="button"
selected="true"
:class="selected"
@click='HeaderFunction'
>
first button
</button>
<button
type="button"
selected="false"
:class="nonselected"
@click='HeaderFunction'
>
second button
</button>
</template>
<script>
export default {
data(){
return{
selected:'btn btn-success btn-sm',
nonselected:'btn btn-danger btn-sm',
}
},
methods: {
callFunction: function (event) {
var selected = event.target.getAttribute('selected');
return alert (selected);
}
}
}
</script>
您需要一个数组和变量来保存当前活动的按钮:
<template>
<button v-for="(item,index) in headerList" :key="index" :class="currentButtonIndex === index ? selected : unselected" @click="chooseHeader(index)">{{ item }}</button>
</template>
<script>
export default
{
data()
{
return {
currentButtonIndex: -1,
selected: 'btn btn-success btn-sm',
unselected: 'btn btn-danger btn-sm',
}
},
computed:
{
headerList()
{
return [
'First button',
'Second button',
]
}
},
methods:
{
chooseHeader(index)
{
this.currentButtonIndex = index;
}
}
}
</script>
