使用VUE对复选框进行选择
实现的功能就是，选中几个复选框，能够返回这几个复选框所在行的管理员用户名。点击全选能够全选，能够返回复选框所在行的管理员用户名。先来看一下HTML<tbody><tr v-for='(item,i) in adminMessageList'><td class="tablecheckbox_td"><...

实现的功能就是，选中几个复选框，能够返回这几个复选框所在行的管理员用户名。点击全选能够全选，能够返回复选框所在行的管理员用户名。
先来看一下HTML
<tbody>
<tr v-for='(item,i) in adminMessageList'>
<td class="tablecheckbox_td">
<!-- :checked=ture 进行布尔判断，来改变当前复选框的状态 checkedList[i].status @change 监听复选框改变 如果改变执行checkchange -->
<input class="tablecheckbox" type="checkbox" :checked=checkedList[i].status @change="checkchange(event,i)">
</td>
<td >{{item.ainNickname}}</td>
<td >{{item.ainCreateTime}}</td>
<td >{{item.ainId}}</td>
<td>
<button id="online" class="btn btn-success btn-xs" type="button" @click="addadmin()">查看</button>
<button id="online" class="btn btn-danger btn-xs" type="button">修改</button>
<button id="online" class="btn btn-danger btn-xs" type="button" @click="deleteSingle(i)">删除</button>
</td>
</tr>
</tbody>关键在于下框内的这一行
我们去@change="checkchange(event,i)中看一下
//用来同步checkedList
checkchange(event,i){
//可以理解为checkedList 就是复选框自己本身的副本 是有很多个复选框的集合 ！！！！！由于 checkedList是自定义 当页面的复选框发生改变的时候，对它本身没有任何直接关系和影响
this.checkedList[i].status = ! this.checkedList[i].status
//更新已选择列表
this.updateChooes();
},
这里面用了一个方法如下
//刷新/更新 choose
updateChooes(){
this.chooseLis = [];//清零
//循环检查判断哪些是已选择的
for (let i = 0; i < this.checkedList.length; i++) {
if (this.checkedList[i].status)
{
this.chooseLis.push(this.adminMessageList[i].ainNickname)
}
}
console.log("ChooseList:-" +this.chooseLis)
}然后再来看一下我们完整的JS
var vue = new Vue({
el: '.App',

adminMessageList: [{ ainNickname: 1, ainCreateTime: "高级效果图", number: 1 }, { ainNickname: 2, ainCreateTime: "中级效果图", number: 1 }, { ainNickname: 3, ainCreateTime: "一般效果图", number: 1 }],
//映射页面上的复选框 被v-for绑定
checkedList:[
{id:1,status:0},
