vue通过后端返回'1'和'0'来对应显示el-checkbox的勾选状态。选中第一个el-checkbox，第二个el-checkbox自动勾选
1、要实现的功能
我要实现的是两个checkbox的状态显示，
两个checkbox的状态根据后台返回的值来定义checkbox状态，
后台返回第一个checkbox的a值是'1''，第二个checkbox的也是b值是'1'，'1' 表示true ，'0' 表示false。
我要实现的就是当选中第一个checkbox后，第二个会checkbox自动勾选，然后第二个勾选不影响第一个，只有第一个checkbox会影响第二个checkbox。并把值返回给后端
如图所示：
2、实现思路：
实现思路是通过computer计算属性里分别写checkbox1和checkbox的属性值，，并且根据'1'还是'0'来 return符合条件的true和false。此时checkbox可以自动勾选。但是勾选checkbox时，提示需要set，于是写来set和get，但是又提示栈溢出。而且通过计算机属性，打印出的v-model绑定checkbox值是undefined。
然后改用data里定义checkbox1和checkbox的v-model值。但是无法初始化或者根据后端返回的值，自动勾选。
3、下面是代码：

你computed一个checked，data里也定义一个checked，不会报冲突？
data里面的数据设置为这样
arr:[
{checked:false,disableds:false},
{checked:false,disableds:false},
]
然后通过v-for循环给每个多选框设置点击事件
ischecked(index){
this.arr[index].checked=!this.arr[index].checked
if(index===0){
this.arr[1].checked=true;
}
},

没看明白现在的问题 自动勾选 可以了吗？
