讓這兩個select相互綁定，讓roleOptions選取值后，worklist彈出得是roleOptions值
<el-select v-model="postForm.projectName" placeholder="請選擇" @change="getList(postForm)">
<el-option
v-for="item in roleOptions"
:key="item.key"
:label="item.label"
:value="item.key">
</el-option>
<el-select v-model="postForm" placeholder="請選擇" value-key="id" @change="getList2(postForm)">
<el-option
v-for="item in worklist"
:label="item.productName"
:value="item">
</el-option>
首先在created里面獲取值，設res為null，傳入getlist中；
async created() {
this.lastWorklist = await api_price_list({},this.queryParam);
let res = null;
this.getList(res)
},
然后在methods中進行判斷
methods: {
async getList(res) {
this.listLoading = true
如果res為null獲取worklist
if(res != null){
this.worklist = [];
如果res里面的獲取數據為s或y則綁定不同的值
if(res.projectName == "s"){
this.lastWorklist.data.list.forEach(item => {
if(item.app == res.projectName){
this.worklist.push(item);
}
});
}
else if(res.projectName == "y"){
this.lastWorklist.data.list.forEach(item => {
if(item.app == res.projectName){
this.worklist.push(item);
}
});
}
}
this.listLoading = false
},
然后在getlist2里面在第二個select組件進行傳值綁定
getList2(res){
if(res.app=="s"){
this.postForm.projectName = "抖音";
}
else if(res.app == "y"){
this.postForm.projectName = "快手";
}
},
