Vue is a progressive JavaScript framework that helps us build complex user interfaces and single-page applications. It is easy to learn, lightweight and flexible, making it one of the most commonly used frameworks by front-end developers. In this article, we will introduce Vue native usage.
Vue native usage refers to integrating Vue.js into a website or application so that local files or individual HTML files can run Vue.js. Vue native usage allows us to develop Vue.js applications on all devices without needing to be connected to the Internet.
To use Vue in a local environment, we need to download and install the Vue.js library file. We can download the latest version of Vue.js from the Vue.js official website (https://vuejs.org/) and introduce the file in the HTML file.
<!DOCTYPE html>
<html>
<head>
<title>Vue本地用法</title>
</head>
<body>
<div id="app">
{{ message }}
</div>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script>
var app = new Vue({
el: '#app',
data: {
message: '欢迎使用Vue本地用法！'
}
})
</script>
</body>
</html>
In this simple example, we create a Vue instance and mount it on the element with the id "app". Next, we define a data object that contains a property called "message" whose value is "Welcome to Vue native usage!". Finally, we introduce the Vue.js library files into the HTML file so that our application can use Vue.js.
Once we add the Vue.js library file in the HTML file and create the Vue instance, we can use all the features of Vue.js. For example, we can use Vue.js’ template syntax and directives in HTML.
We can use the v-bind directive in Vue.js to bind HTML attributes to data in the Vue.js instance. For example, we can bind a button's value property to a property in a message data object.
<!DOCTYPE html>
<html>
<head>
<title>Vue本地用法</title>
</head>
<body>
<div id="app">
{{ message }}
<input type="button" v-bind:value="message" />
</div>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script>
var app = new Vue({
el: '#app',
data: {
message: '欢迎使用Vue本地用法！'
}
})
</script>
</body>
</html>
In this example, we define an input button whose value attribute is bound to the message attribute in the Vue instance. This means that when we change the message value, the button's value automatically updates as well.
We can also use the v-for directive of Vue.js to display items in the array. For example, we can create a data object that contains an array called "items" and use a v-for loop to iterate through the array, dynamically creating HTML elements.
<!DOCTYPE html>
<html>
<head>
<title>Vue本地用法</title>
</head>
<body>
<div id="app">
<ul>
<li v-for="item in items">{{ item }}</li>
</ul>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script>
var app = new Vue({
el: '#app',
data: {
items: ['Vue', 'React', 'Angular']
}
})
</script>
</body>
</html>
In this example, we define a data object containing an array named "items" and bind it to the Vue instance. We then use the v-for directive to loop through the array in the HTML and create a variable called "item" to store the value of each array element.
The above is an introduction and examples of local usage of Vue. We can learn more about the usage and functions of Vue.js in the Vue.js official documentation.
