关于Vue的v-for渲染出多个元素之后如何单独添加属性

问题：我们想要在一个表单里面。有多个按钮，但是点击到只剩下一个按钮之后那个按钮不可点击。

原先：

< template scope= "scope" >

< el-switch v-model=" scope. row. state"

        :on-value=1

        :off-value=0 on-text= "否" off-text= "是"

v-if=" scope. row. assign== 1"

        @change=" setChange( scope. $index, scope. row)" >

el-switch >

template >

解决方法：我们在可以每一个switch里面添加一个属性，之后在属性里面做判断

< template scope= "scope" >

< el-switch v-model=" scope. row. state"

        :on-value=1

        :off-value=0 on-text= "否" off-text= "是"

v-if=" scope. row. assign== 1"

        @change=" setChange( scope. $index, scope. row)"

        :disabled="scope.row.state==1&&isDisabled">

el-switch >

template >

之后在script中添加如下方法，判断每次点击的时候。剩下的switch的状态。在做判断

setChange( index, row) {

let arr = [];

// 改变后的值

if( row. state== 1){

row. state= 0;

} else{

row. state= 1;

}

this. list1. forEach( element => {

if( element. assign== 1&& element. state== 1){

arr. push( 1);

}

});

// console.log(arr.length);

//判断最后一个开关是否禁用

if( arr. length<= 1){

this. isDisabled= true;

} else{

this. isDisabled= false;

}
