我試圖使用Vue輸入來記錄一些簡單的數據,但由於某種原因,按鈕調用的方法add()
被調用兩次。Vue方法在按鈕單擊時調用兩次
<el-steps :active="addItem.count" finish-status="success" class="form-items" style="padding-left: 0px">
<el-step title="category"></el-step>
<el-step title="subcategory"></el-step>
<el-step title="data"></el-step>
</el-steps>
<el-form ref="form" :model="addItem" label-width="120px" style="padding: 20px;">
<el-input :placeholder="placeholder" v-model="addItem.text"></el-input>
<div id="add-item-buttons">
<el-form-item class="form-items">
<el-button type="primary" @click="add">Create</el-button>
<el-button>Clear</el-button>
</el-form-item>
</div>
</el-form>
<script>
export default {
methods: {
add(){
switch(this.addItem.count){
case 1:
this.addItem.category = this.addItem.text;
console.log('category set to: ' + this.addItem.category);
this.addItem.text = '';
this.addItem.count++;
case 2:
this.addItem.subcategory = this.addItem.text;
console.log('category set to: ' + this.addItem.subcategory);
this.addItem.text = '';
this.addItem.count++;
case 3:
if (this.addItem.kks.show){
this.addItem.kks.name = this.addItem.text;
}
if (this.addItem.document.show){
this.addItem.document.name = this.addItem.text;
}
if (this.addItem.product.show){
this.addItem.product.name = this.addItem.text;
}
}
},
computed: {
placeholder: function(){
switch(this.addItem.count){
case 1:
return 'ADD A CATEGORY TO YOUR ITEM';
case 2:
return 'ADD A SUBCATEGORY TO YOUR ITEM';
case 3:
return 'GIVE YOUR ITEM A NAME';
}
},
active: function(){
return true;
}
},
data() {
return {
addItem: {
open: false,
count: 1,
category: '',
subcategory: '',
text: ''
}
}
...
</style>
下面是我在控制檯中看到,當我點擊 '創建':
category set to: category 1
category set to:
編輯:原來我犯了一個錯字,並寫了「類別設置爲'我的第二個開關案例,我的意思是'子類別'。顯然,案例1和案例2正在評估中,而不是案例1的兩次。這裏是新的控制檯日誌時,它的固定:
category set to: category 1
(unknown) subcategory set to:
而沒有切換來添加您的類別,然後,它會直接到項目。
任何人都可以看到發生了什麼問題嗎?
謝謝!猜猜我需要查看switch語句。 –
我很高興能幫上忙。 –
