Topic: MDBSelect requires mutable options to function
Expected behavior
I should be able to create multiple Selects from the same array of options without having to create multiple copies of the array and have each select work independently - even when using the same code.
Actual behavior
I have to run extra code to create multiple copies of the options array for the MDBSelect component to function correctly when building forms that use a select in a v-for loop and all share the same options array.
Resources (screenshots, code snippets etc.)
This is horribly inefficient. Additionally, looking at the MDBSelect.vue component, I don't see any time where 'update:options' is emitted. So this requirement can go away entirely.
Please remove 'update:options' from the emits section of the component.
I don't currently have a snippet to share beyond the following:
<div v-for="item in items" v-bind:key="item.id">
<div class="input-group">
<MDBSelect :label="`${item.name} Assignment`" :options="selectOptions" :selected="getSelectedValueForItem(item.id)" @update:selected="(x:number)=>changeSelectionForItem(item.id,x)" />
</div>
</div>
<!--
this.selectOptions is a prop defined via props: ['selectOptions']
getSelectedValueForItem is a function of the component:
getSelectedValueForItem(x:number)
{
let selectedOptionId = -1;
const results = this.editItem.mappings.filter((y:MappedItem)=>y.itemId === x);
if(results.length > 0) selectedOptionId = results[0].optionId;
return selectedOptionId;
}
changeSelectionForItem is a function of the component:
changeSelectionForItem(itemId:number,newSelection:number)
{
if(newSelection < 0)
{
this.editItem.mappings = this.editItem.mappings.filter((y:MappedItem)=>y.itemId === itemId);
}
else
{
const results = this.editItem.mappings.filter((y:MappedItem)=>y.itemId === itemId);
if(results.length > 0)
{
this.editItem.mappings = this.editItem.mappings.map((y:MappedItem)=>{
if(y.itemId === itemId) y.optionId = newSelection;
return y;
})
}
else
{
this.editItem.mappings.push({
itemId: itemId,
optionId: newSelection
})
}
}
this.$emit('update:editItem',this.editItem);
}
