script部分：

<script>
var proData = [{

}, {
"name": "j2ax"
}, {
"name": "j3ax"
}, {
"name": "j4ax"
}]
export default {
 name: 'hello',
 data() {
return {
 proData: proData,
 selectArr: []
 }
 },
 created() {
this.$http.get('/api/home').then(function(response) {
 response = response.body;
this.proData = response.data;
 })
 },
 methods: {
 del() {
let arr = [];
var len = this.proData.length;
for (var i = 0; i < len; i++) {
if (this.selectArr.indexOf(i)>=0) {
 console.log(this.selectArr.indexOf(i))
 }else{
 arr.push(proData[i])
 }
 }

this.proData = arr;
this.selectArr = []
 },
 selectAll(event) {
var _this = this;
 console.log(event.currentTarget)
if (!event.currentTarget.checked) {
this.selectArr = [];
 } else { //实现全选
 _this.selectArr = [];
 _this.proData.forEach(function(item, i) {
 _this.selectArr.push(i);
 });
 }
 }
 }
}
</script>
