通过索引进行删除，进行测试，是否获取其索引：
测试效果：
测试代码，在vue中定义一个空的数组，以便后面进行数据的绑定：
data:{
imgUrl:'../res/images/',
imgName:'lovely.ico',
goods:{
id:'',
name:'',
price:'',
num:'',
type:''
},
goodsType:['零食','电子产品','生活用品'],
goodsArry:[
{id:'',name:'可乐',price:3.5,num:,type:'零食'},
{id:'',name:'GTX2080',price:,num:,type:'电子产品'},
{id:'',name:'牙刷',price:,num:,type:'生活用品'}
],
colNum:,
delArray:[]
},
测试的HTML代码：
<tr v-for="(item,index) in goodsArry" :key="item.id">
<td>{{index}}</td>
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.price}}</td>
<td>{{item.num}}</td>
<td>{{item.type}}</td>
<td>
<button @click="delGoods(index)">删除</button>
</td> <td>
<input type="checkbox" :value="index" v-model="delArray"/> </td>
</tr>
{{delArray}}
实现选择删除商品功能，通过遍历索引数组：
为了保证数据列表从小排到大:
测试使其列表从小排到大
测试代码：
delSelected(){
this.delArray.sort((a,b)=>{
return a-b;
});
console.log(this.delArray);
for(var i=;i<this.delArray.length;i++)
{
this.goodsArry.splice(this.delArray[i]-i,);
}
this.delArray=[];
}
}
最终实现该功能的总代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>商品管理------创建页面与部分数据</title>
<script src="../js/vue.js"></script> <script> window .onload= () =>{
new Vue({
el:"#container",
data:{
imgUrl:'../res/images/',
imgName:'lovely.ico',
goods:{
id:'',

price:'',

},
goodsType:['零食','电子产品','生活用品'],
goodsArry:[
{id:'',name:'可乐',price:3.5,num:,type:'零食'},
{id:'',name:'GTX2080',price:,num:,type:'电子产品'},
{id:'',name:'牙刷',price:,num:,type:'生活用品'} ],
colNum:,
delArray:[]//删除选中的索引 },
methods:{
addGoods(){ this.goodsArry.push(this.goods);
this.goods={};
},
delGoods(index){ this.goodsArry.splice(index,);
},
clearGoodsArry(){ this.goodsArry=[];
},
delSelected(){ this.delArray.sort((a,b)=>{
return a-b;
}); console.log(this.delArray); for(var i=;i<this.delArray.length;i++)
{
this.goodsArry.splice(this.delArray[i]-i,);
}
this.delArray=[];
} }
});
}
</script>
