这是一个引入Vue.js库的示例代码。通过在HTML文件中添加该代码,可以将Vue.js库引入到你的项目中。具体代码如下:
```html
<script src="https://unpkg.com/vue@next"></script>
```
这段代码会从指定的URL加载Vue.js库,并使其可用于你的项目。请确保在使用该代码之前,你已经连接到互联网。

好的,以下是结合分页功能的完整代码:
<!DOCTYPE html>

<div id="app">

</div>

</div>
<div id="houseList"></div>

<iframe src="footer.html" frameborder="0" scrolling="no" width="100%" height="245px"></iframe>
</div>
<script src="/BookShopSystem_war/layui/layui.js"></script>
<script>
layui.use('laypage', function(){
var laypage = layui.laypage;
var vm = new Vue({
el: '#app',
data: {
bookAll: [],
current: 1,
totalPage: 1,
currentBookAll: []
},
mounted: function() {
var _this = this;
axios.get('/BookShopSystem_war/book/all')
.then(function(response) {
_this.bookAll = response.data;
_this.totalPage = Math.ceil(_this.bookAll.length / 10);
_this.currentBookAll = _this.bookAll.slice(0, 10);
laypage.render({
elem: 'pagination',
count: _this.bookAll.length,
curr: _this.current,
limit: 10,
layout: ['prev', 'page', 'next', 'skip'],
jump: function(obj, first){
if(!first){
_this.currentBookAll = _this.bookAll.slice((obj.curr-1)*obj.limit, obj.curr*obj.limit);
}
}
});
})
.catch(function(error) {
console.log(error);
});
}
});
});
</script>
</body>
</html>
注意:这里的分页功能使用了 layui 的 laypage 组件,需要在页面中引入 layui.js 和 layui.css,并且需要在 Vue 的 mounted 钩子函数中调用 laypage.render() 方法来渲染分页组件。同时,需要注意在分页回调函数中更新当前显示的数据。

好的,下面是将这个页面改为 Vue 3 的写法:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue-upload-component Test</title>
<script src="https://unpkg.com/vue@next"></script>
<script src="https://unpkg.com/vue-upload-component@3.0.0-beta.6"></script>
</head>
<body>
<div id="app">
<ul>
<li v-for="file in files">{{file.name}} - Error: {{file.error}}, Success: {{file.success}}</li>
</ul>
<file-upload
ref="upload"
v-model="files"
:post-action="'/post.method'"
:put-action="'/put.method'"
@input-file="inputFile"
@input-filter="inputFilter"
>
Upload file
</file-upload>
<button v-show="!$refs.upload || !$refs.upload.active" @click.prevent="$refs.upload.active = true" type="button">Start upload</button>
<button v-show="$refs.upload && $refs.upload.active" @click.prevent="$refs.upload.active = false" type="button">Stop upload</button>
</div>
<script>
const { createApp, ref } = Vue;
const { VueUploadComponent } = vueUploadComponent;
createApp({
setup() {
const files = ref([]);
const inputFile = (newFile, oldFile) => {
if (newFile && oldFile && !newFile.active && oldFile.active) {
// Get response data
console.log('response', newFile.response);
if (newFile.xhr) {
// Get the response status code
console.log('status', newFile.xhr.status);
}
}
};
const inputFilter = (newFile, oldFile, prevent) => {
if (newFile && !oldFile) {
// Filter non-image file
if (!/\.(jpeg|jpe|jpg|gif|png|webp)$/i.test(newFile.name)) {
return prevent();
}
}
// Create a blob field
newFile.blob = ''
let URL = window.URL || window.webkitURL
if (URL && URL.createObjectURL) {
newFile.blob = URL.createObjectURL(newFile.file)
}
};
return {
files,
inputFile,
inputFilter
}
},
components: {
'file-upload': VueUploadComponent
}
}).mount('#app');
</script>
</body>
</html>
```
主要变化如下:
- 使用 `createApp` 创建 Vue 实例;
- 使用 `ref` 创建响应式变量;
- 使用 `setup` 函数代替 `data` 属性;
- 使用 `VueUploadComponent` 替代 `vueUploadComponent`;
- 使用 `v-bind` 缩写 `:` 替代 `v-bind`;
- 使用 `v-on` 缩写 `@` 替代 `v-on`;
- 使用 `file-upload` 替代 `file-upload`。
