Vue Select in the drop-down box with a v - model binding one value, use v

Vue Select in the drop-down box with a v - model binding one value, use v - for multiple traversal, change a drop-down box options, other changes will be more than the traverse on the way out, change the value of one, the other will change, how should I solve?? Don't let them linkage

CodePudding user response:

Do not bind the same v - model

CodePudding user response:

I this is cycle of data, only a data binding

CodePudding user response:

Didn't understand what do you want to express? More clearly

Hello World,

I come out in the circulation data v - model can only be bound to the same data,

CodePudding user response:

You are now have multiple select the drop-down selection box? Every one of them was cycle?

CodePudding user response:

1. Modify the source data, add a selectVal properties, and under the drop-down menu first assignment here
This. GoodsList. ForEach ((item, index)=& gt; {
Item. Checkd=false
Item. The index=index
Item. SelectVal=item. Attr_name [0]
})

2. Use just manually add attributes in the view layer, gets an attribute value
{{item. SelectVal}} & lt;/span>

3. Change the source data in the down selection box new selectVal attribute value of
SelectTypeHandle (item, e, index) {
Item. SelectVal=e.c. with our fabrication: urrentTarget. Dataset. The value;
},
