分享Vue.js在组件中如何遍历数据
如上图：就是把下面这个数组遍历到上面的tr中去。
下面是js代码
<script type="text/javascript">
var pageBar = new Vue({
el: '.page-bar',
data: {
all: 8, //总页数
message:"121311",
cur: 1//当前页码
},
watch: {
cur: function(newValue , oldValue){
console.log(newValue);
Vue.component('my-component',{
template: "<tr> <td>{{ }}</td> <td> #sex# </td> <td> #age# </td> </tr>",
data:function(){
return {
lists: [
{id: 1, name: 'luozh1', sex: 'dsds',age:17},
{id: 2, name: 'luozh2', sex: 'dsds',age:18},
{id: 3, name: 'luozh3', sex: 'dsds',age:19},
{id: 4, name: 'luozh4', sex: 'dsds',age:20},
{id: 5, name: 'luozh5', sex: 'dsds',age:21},
{id: 6, name: 'luozh6', sex: 'dsds',age:22},
{id: 7, name: 'luozh7', sex: 'dsds',age:23},
{id: 8, name: 'luozh8', sex: 'dsds',age:24}
]
}
}
})
}
},
methods: {
btnClick: function(data){//页码点击事件
if(data != this.cur){
this.cur = data
}
},
pageClick: function(){
console.log(this.lists)
console.log('现在在'+this.cur+'页');
}
// pageClick:function(){
// //发送get请求
// this.$http.get('http://127.0.0.1/lng/Home/index/page_ajax').then(function(res){
// res =JSON.parse(res)
// console.log(res.name)
// },function(){
// alert('请求失败处理'); //失败处理
// });
// }
},
computed: {
indexs: function(){
var left = 1;
var right = this.all;
var ar = [];
if(this.all>= 5){
if(this.cur > 3 && this.cur < this.all-2){
left = this.cur - 2
right = this.cur + 2
}else{
if(this.cur<=3){
left = 1
right = 5
}else{
right = this.all
left = this.all -4
}
}
}
while (left <= right){
ar.push(left)
left ++
}
return ar
}
}
})
