Example of Code
<div v-for="item in dataItems">
<div v-if="enableEdit">
<input type="text" v-model="name">
</div>
<div v-else>
{{name}}
</div>
<button @click="enableEdit = true">click</button>
This code snippet is currently not functioning properly due to the fact that enableEdit is not declared as a variable inside the script.
Is it feasible to create a local variable within v-for?
To declare a variable inside of a template may seem impossible, but you can actually achieve the same outcome by following these steps.
Modify your template like this:
<div v-for="item in dataItems" :key="item.id">
<div v-if="editedElementId !== item.id" @click="editItem(item.id)">
{{item.name}}
</div>
<div v-else>
<input type="text" placeholder="New name..." v-model="item.name" />
</div>
</div>
Always remember to include :key when using v-for.
Next, insert editedElementId: null within the data section and create a new method called editItem:
methods: {
editItem(id) {
this.editedElementId = id
}
}
Check out this link for a demo.
To handle cases where a value is undefined, you have the option to create a specific field name that pertains to the current iteration of the for loop:
<div v-for="(month, mi) in months" :key="mi">
<div v-for="(day, di) in days" :key="di">
... <div v-if="generated_fields['month_' + mi + '_day_' + di]">
... <you_can_utilize_here> generated_fields['month_' + mi + '_day_' + di] ...
...
data:function(){
return{
...
generated_fields:{}//initially set as undefined, automatically populates when entered
...
}
