this should be what you want
change(val){
const length = val.length
console.log(val[length - 1])
}this is an array. You should find the index value manually
you can listen for change events:
<template>
<el-select
@change="valueChange"
v-model="value5" multiple placeholder="">
<el-option
v-for="item in options"
:key="item.value"
:label="item.label"
:value="item.value">
</el-option>
</el-select>
<el-select
v-model="value11"
multiple
collapse-tags
style="margin-left: 20px;"
placeholder="">
<el-option
v-for="item in options"
:key="item.value"
:label="item.label"
:value="item.value">
</el-option>
</el-select>
</template>
<script>
export default {
data() {
return {
options: [{
value: '1',
label: ''
}, {
value: '2',
label: ''
}, {
value: '3',
label: ''
}, {
value: '4',
label: ''
}, {
value: '5',
label: ''
}],
value5: [],
value11: []
}
},
methods:{
valueChange:function(){
console.log(this.value5)
}
}
}
