我創建了一個表，并在表中回圈遍歷物件陣列。
<table class="table table-striped" v-if="bins.length > 0">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Location</th>
<th scope="col" class="text-end">Action</th>
</tr>
</thead>
<tbody>
<tr v-for="(bin, index) in bins" :key="index">
<th scope="row">{{index 1}}</th>
<td ref="txtLocaton" contenteditable="false" v-text="bin.binlocation"></td>
<td class="text-end">
<div class="action-btn">
<button @click="btnEdit"><fa icon="edit" /> Edit</button>
<button><fa icon="trash" /> Delete</button>
</div>
</td>
</tr>
</tbody>
</table>
我想要的是在“編輯”按鈕上單擊，我想將 contenteditable 屬性從 false 更改為 true。
這是 data() 的代碼
<script>
export default {
data(){
return{
bins:[
{
binlocation: '11 Garden Block, New City',
},
{
binlocation: 'Ali Towers, Lahore'
},
{
binlocation: 'The Mall Road'
}
]
}
},
methods:{
btnEdit(){
console.log(this.$refs.txtLocaton)
}
}
}
</script>
我正在考慮使用“ref”更改屬性，但是當我對其進行控制臺時，它會在單擊按鈕時回傳最后一個陣列
uj5u.com熱心網友回復：
您可以將contenteditable鍵存盤在bins陣列中（false最初？）：
[{
binlocation: '11 Garden Block, New City',
contenteditable: false,
}, {
binlocation: 'Ali Towers, Lahore',
contenteditable: false,
}, ...]
然后將contenteditable td屬性系結到這些值（而不是false直接傳遞）：
<td ref="txtLocaton" :contenteditable="bin.contenteditable" v-text="bin.binlocation"></td>
當按下“編輯”按鈕時，只需根據需要切換值：
<button @click="bin.contenteditable = !bin.contenteditable"><fa icon="edit" /> Edit</button>
或者
<button @click="btnEdit(index)"><fa icon="edit" /> Edit</button>
btnEdit(index) {
this.bins[index] = !this.bins[index];
}
uj5u.com熱心網友回復：
嘗試如下代碼段（您可以將索引傳遞給您的方法并將 contenteditable 屬性系結到資料屬性）：
new Vue({
el: '#demo',
data(){
return{
bins:[
{binlocation: '11 Garden Block, New City',},
{binlocation: 'Ali Towers, Lahore'},
{binlocation: 'The Mall Road'}
],
editable: null
}
},
methods:{
btnEdit(index){
this.editable = index
}
}
})
Vue.config.productionTip = false
Vue.config.devtools = false.editable {
border: 2px solid violet;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<table class="table table-striped" v-if="bins.length > 0">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Location</th>
<th scope="col" class="text-end">Action</th>
</tr>
</thead>
<tbody>
<tr v-for="(bin, index) in bins" :key="index">
<th scope="row">{{index 1}}</th>
<td ref="txtLocaton" :contenteditable="index === editable" :class="index === editable && 'editable'" v-text="bin.binlocation"></td>
<td class="text-end">
<div class="action-btn">
<button @click="btnEdit(index)"> Edit</button>
<button> Delete</button>
</div>
</td>
</tr>
