How to set the lock for vue function

The .sync modifier can be used in Vue components to set component locks, implement bidirectional binding between component properties, and prevent modifications to one component from overwriting modifications to another component. How to use: 1. Define the data attributes to lock in the parent component; 2. In the child component, use the .sync modifier to bind the properties of the child component to the data attributes of the parent component.

Setting component locks in Vue

In Vue, you can use the .sync modifier to set a lock for the component. This modifier allows you to bidirectionally bind component properties to the properties of another component and prevents modifications to one of the components from overwriting modifications to another component.

How to use:

To use the .sync modifier in a Vue component, follow these steps:

1. In the parent component, define a data attribute that stores the value to be locked.
2. In a child component, use the .sync modifier to bind the properties of the child component to the data properties of the parent component.

Example:

 <code class="html"><!-- 父级组件--> <template> <child-component :locked-value.sync="lockedValue"></child-component> </template> <script> export default { data() { return { lockedValue: 0 } } } </script> <!-- 子级组件--> <template> <input v-model="lockedValue"> </template> <script> export default { props: [&#39;lockedValue&#39;] } </script></code>

In the above example, the parent component defines a lockedValue data property, and the child component uses the .sync modifier to bind the lockedValue property to the lockedValue data property of the parent component.

Effect:

After using the .sync modifier, when the parent component modifies lockedValue data attribute, lockedValue property of the child component is also updated, and vice versa. Additionally, because the .sync modifier creates a two-way binding between the parent and child components, modifications to one component will not override modifications to the other component.

advantage:

Setting component locks with .sync modifiers has the following advantages:

• Bidirectional data binding: It allows data sharing between components in both directions, thereby improving code maintainability.
• Prevent overwrite: It prevents modifications to one component overwrites modifications to another component, thus ensuring data consistency.
• Simplified code: It provides a cleaner way to manage communication between components than using events and listeners.
