How to implement the function of clicking to select a product list in vue

Recently I was working on an e-commerce website and needed to implement the function of clicking to select a product list. I took this opportunity to learn the Vue framework.

In Vue, it is very simple to click on the selected list. You only need to use the v-on instruction and v-bind instruction provided by Vue.

First, define a product list in the template, with a checkbox behind each product.

 
  {{item.name}} 
 

The v-for instruction here is a loop instruction in Vue, which is used to traverse each element in the itemList array. The v-bind directive is an attribute binding directive in Vue, which can bind data in Vue to HTML elements. The v-model directive is a two-way binding directive in Vue, which can achieve two-way synchronization of data.

In data, declare the itemList array and initialize the id, name and checked attributes of each element.

data() { return { itemList: [ { id: 'item1', name: '商品1', checked: false }, { id: 'item2', name: '商品2', checked: false }, { id: 'item3', name: '商品3', checked: false } ] } }

When the user clicks on the checkbox, the click event will be triggered. We only need to define a toggleCheck method in methods to invert the status of the currently selected checkbox.

methods: { toggleCheck(item) { item.checked = !item.checked; } }

Finally, use the v-on directive in the template to bind the click event and call the toggleCheck method.

In this way, the function of clicking on the selected list can be realized.

To summarize, Vue is very simple to implement a click-to-select list. You only need to use the v-for, v-bind, v-model and v-on instructions provided by Vue to bind the data in HTML and Vue. Defined, two-way synchronization of data and binding of events can be achieved. The Vue framework is not only low-cost to learn, but also very suitable for developing small and medium-sized projects. If you also want to improve your front-end skills, you might as well learn the Vue framework!
