To implement the navigation bar function in Vue, we can implement the navigation bar as a separate component. This makes it easy for us to modify and customize, and there are many ways to add a navigation bar, such as using Vue's document. position attribute or using the vue-dialog-position attribute to add a navigation bar. Here, we use the document.position property as an example to introduce the method of implementing the navigation bar function in Vue. In the above code, we need to define a subcomponent of the navigation bar first, as follows:
-
1. Create subcomponents
In this code, we need to set the button.dialog-position property to true first, and then add a flag. The user sees the value of the button.dialog-position property through the button.dialog-position property. In this code, we first need to create a subcomponent of the document.position property and add the flag.position property to it, as shown below: Then we can view its specific value by clicking the button.dialog-position property:
-
1. Property setting
In this code, we first need to set the button.dialog-position property to true, so that the user can view the content of the navigation bar through the DOM. Then we set the button.dialog-position property to the flag.position property so that when the user clicks on the navigation bar, its value will be displayed. In this code, we first need to add a DOM object, and then add a flag. position attribute to this DOM object, so that when the user clicks on the navigation bar, its value will be displayed.

2. Add flag.position attribute

2. Add navigation bar components
In order to implement the above navigation bar component, we need to add the navigation bar component to the vue.co unt.onload() method. Vue's onload () method is a callback method. When we need to use the onload () method, we only need to pass the onload () method to it. In the above code, we first define a new component called function.document, and add a function.document to the component, set it as the parent component, and add a get_static method to the component. In order to facilitate future modification and customization of the navigation bar, we also need to add and delete subcomponents of the navigation bar. In order to achieve the above operations, we can modify the parent component of the navigation bar component to vue.print ln (). Since we defined the subcomponent function.document.position, when adding a new subcomponent, we need to set the position property of the parent component to vue-dialog-position. As follows: In the above code, we use two parameters to indicate the position and width of the navigation bar. When we want to set the position of the navigation bar to the value of the position attribute of the parent component in the parent component, we can use the following code to achieve it. Through the above code, we can see that when the position of the navigation bar is set to the value of the position property of the parent component in the parent component, the navigation bar will be set to the value of the position property of the parent component in the parent component. In addition, in order to avoid the incomplete display of the width of the navigation bar in the view, we also need to set the value of the width of the navigation bar. To do this, we use the following code to achieve. In the above code, we first set document.dwd.length=0. After that, when we render the parent page, we can use the navigation bar width to get the view element width of the current page. Then we gave dwd. length=0 in the vue-dialog-position () method of a subcomponent. Next, we also need to add a position property value of 0 to the parent component to the child component. In the above code, we use the following code to set the width of the navigation bar:
-
3. Add content
First, we need to add a subcomponent to display the corresponding subcomponent on the page. Therefore, we first add a subcomponent to the initial page, as follows: Next, we need to add some content to the navigation bar for our convenience. In the above code, we created a child component called layout and created a navigation bar content in it. The specific implementation is as follows: Next, we need to add some attributes to the layout in order to set it. For example: In the above code, we added some properties to the layout: When the user clicks the "start" button, the event of my-activity will be triggered.
Here is a code example for a simple Vue navbar component:
```html
<template>
<nav>
<ul>
<li v-for="item in items" :key="item.id">
<router-link :to="item.path">{
{ item.title }}</router-link>
</li>
</ul>
</nav>
</template>
<script>
export default { data() { return { items: [{ id: 1, title: 'Home', path: '/' },{ id: 2, title: 'Products', path: '/products' },{ id: 3, title: 'About us ', path: '/about' },{ id: 4, title: 'Contact us', path: '/contact' },],};}, }; </script> ```
In the above code, we use Vue's `v-for` instruction to traverse each menu item in the navigation bar, and use the `router-link` component to realize the routing jump. Among them, the `items` array stores the information of each menu item, including the title and path of the menu item. In actual development, you can modify the number and content of menu items according to your own needs.
