Vue.js + 获取 ul 的选定 li 项

Question

I have a list displayed like a dropdown -

Each of the items except 'Create New Filter' is bound to a key so i can uniquely identify the li items.

I want to know how can i get the selected li item on save and do operations accordingly

What would be the good approach for this so i can understand when 'Create new filter' is clicked or when other li items are selected

Below is the code -

 <ul>
     <li v-on:click="create">Create New</li>
     <li v-for="item in list" :key="item.id" v-on:click="Change(item.id,item.text)">{{ item.text }}</li>
</ul>

As per my understanding this approach is not good, I am not sure why you are building dropdown by using <ul> and <li> instead of select element as it is a form element and provide a better way to get the selected option value by the help of v-model directive.

Anyhow I worked as per your requirement and came up with the solution.

 var app = new Vue({ el: '.dropdown', data: { list: [{ id: 1, text: 'First Filter' }, { id: 2, text: 'First Filter 2021' }, { id: 3, text: 'Full Filter' }], selectedListItem: null }, methods: { create() { console.log('New filter Create Called'); }, getSelected (item) { this.selectedListItem = item; }, save() { if (this.selectedListItem) { console.log(this.selectedListItem); } else { console.log('No list option selected'); } } } })
