When querying the document, it is said that to get the value selected by select, you can use V-model to bind it. But I don’t just choose ID, I need to record ID and name.
Then I found out that the value binding value was the value passed to the V-model binding, so I changed the original: value = “” to: value = “dr” so that I could pass the currently selected list entire to the v-model, but that’s the problem.Well, no matter which option you choose, select only shows that the last item in the drugs is selected, but the data obtained by V-model is the one I just selected.

No matter which item to choose.

It shows that the last D drug has been selected.

In fact, change just printed out the A drug.


<el-select v-model="choosedata"  placeholder="Please select "@change=" selectchange ">";< el-option v-for= "Dr in drugs": key= "": label= ""Value= "Dr" > < /el-option>< /el-select>


          drugs: [
                { id: 1, name: 'ADrugs' ',{id: 2, name:'B drug ',{id: 3, name:'C drug ',{id: 4, name:'D drug '.]}}Methods:{Selectchange () {Console.log (this.choo);}}

Of course, there is no problem in specifying the display of value= “” or “value=” selector.
But it can not achieve the purpose of obtaining two values at the same time.
