How to pass parameters for vue function
There are two main ways to pass parameters to Vue.js functions: pass data using slots or bind functions using bind, and provide parameters: pass parameters using slots: pass data in component templates, accessed within components and used as parameters of functions. Pass parameters using bind binding: bind function in Vue.js instance and provide function parameters.
Passing parameters of function in Vue.js
How to pass parameters to a function in Vue.js
In Vue.js, there are two main ways to pass parameters to a function:
- Use slot : Slot allows you to pass data in the HTML template of the component. Within the component, you can access the data passed by the slot and use it as a parameter to the function.
- Use bind binding : bind allows you to bind functions in Vue.js instances. During binding, you can provide the parameters of the function.
Pass parameters using slots
<code class="html"><!-- 父组件--> <template> <my-component> <!-- 向my-component 组件传递参数--> <param>{{ message }} </my-component> </template> <!-- 子组件--> <template> <div> <!-- 接收父组件传递的参数--> <p>{{ slot }}</p> </div> </template> <script> export default { props: ['slot'] } </script></code>
Pass parameters using bind binding
<code class="html"><!-- 父组件--> <template> <my-component :click="greet('Alice')"></my-component> </template> <!-- 子组件--> <template> <div> <button> Greet </button> </div> </template> <script> export default { methods: { greetUser() { this.$emit('greet', this.username); } } } </script></code>
In the example above, the parent component uses :click binding to pass a function with parameters to the child component. The child component calls the function using the @click event listener and takes the passed argument as an argument.

How can you optimize the re-rendering of large lists or complex components in Vue?
Jun 07, 2025 am 12:14 AM
Methods to optimize the performance of large lists and complex components in Vue include: 1. Use the v-once directive to process static content to reduce unnecessary updates; 2. implement virtual scrolling and render only the content of the visual area, such as using the vue-virtual-scroller library; 3. Cache components through keep-alive or v-once to avoid duplicate mounts; 4. Use computed properties and listeners to optimize responsive logic to reduce the re-rendering range; 5. Follow best practices, such as using unique keys in v-for, avoiding inline functions in templates, and using performance analysis tools to locate bottlenecks. These strategies can effectively improve application fluency.

How can v-model be used for two-way data binding on custom components in Vue?
Jun 06, 2025 am 11:41 AM
To use v-model to implement two-way binding of custom components in Vue, you must first understand its working mechanism. For custom components, you need: 1. Receive a prop named modelValue; 2. Trigger an event named update:modelValue. By default, it will be parsed to, so the component needs to use:value="modelValue" and $emit('update:modelValue') to synchronize the data. In addition, the prop and event names can be customized via model:{prop:'checked',event:'change'}, which are suitable for different types of components such as switches
