What is a foreach loop?

A foreach loop is a loop structure that traverses each element in an array or object. It allows developers to perform specific actions on each element.

How to use foreach loop

The foreach in Vue.js loops using the v-for directive. The syntax is as follows:

 <code class="html"><template> <ul> <li v-for="item in items">{{ item }}</li> </ul> </template> <script> export default { data() { return { items: [&#39;香蕉&#39;, &#39;苹果&#39;, &#39;橘子&#39;] } } } </script></code>

Syntax description

• v-for directive: means that this is a foreach loop.
• item : The alias for each element in the loop.
• items : The array or object to traverse.
• {{ item }} : Output each element in the loop.

Rendering results

 <code class="html"><ul> <li>香蕉</li> <li>苹果</li> <li>橘子</li> </ul></code>

Other usages

The foreach loop can also be used to traverse objects:

 <code class="html"><ul> <li v-for="item in object">{{ item.name }}</li> </ul></code>

When traversing the object, the alias item will be an object containing key-value pairs.

hint

• Make sure items array or object is responsive so that the loop will update as well when it changes.
• v-for directive can be combined with the v-bind directive to bind attributes for each element in the loop.
