Vue 中如何实现日期范围选择器?
日期范围选择器是现代 Web 应用程序中经常用到的一种界面组件。它允许用户从一个日期范围中选择一个日期或者一个时间段。对于需求为日期范围选择器的 Web 应用程序开发,Vue.js 是一个非常好的选择。
Vue.js 是一个用于构建用户界面的渐进式 JavaScript 框架,它允许开发者使用组件化的方式来构建复杂的交互式界面。在这篇文章中,我们将介绍如何使用 Vue.js 来创建一个日期范围选择器组件。
- 组件结构
首先,让我们来定义一下组件的结构。我们需要一个包含两个选择器的容器,一个用于选择开始日期,另一个用于选择结束日期。这两个选择器都应该包括一个日历组件和一个输入框,用户可以在输入框中直接输入日期,也可以通过日历选择器来选择日期。
在 Vue 中,组件通常采用树形结构来组织,我们可以定义一个父组件,然后将两个日期选择器组件作为它的子组件。父组件负责管理数据,子组件负责展示数据和与用户交互。代码如下:
<template> <div> <date-selector v-model="startDate"></date-selector> <date-selector v-model="endDate"></date-selector> </div> </template> <script> import DateSelector from './DateSelector.vue' export default { components: { DateSelector }, data () { return { startDate: '', endDate: '' } } } </script>
- 日历组件
接下来,让我们来实现日历组件。这个组件将允许用户在一个日历中选择日期,并将选择的日期显示在输入框中。我们可以使用 Vue.js 的 v-model 指令来实现输入框和数据绑定。代码如下:
<template> <div class="date-selector"> <input :value="dateString" @blur="handleChange" @keydown.enter="handleChange"> <svg @click="showCalendar" class="icon icon-calendar"> <use xlink:href="#calendar" /> </svg> <div v-if="show" class="date-calendar"> <calendar :date="date" @change="updateDate"></calendar> </div> </div> </template> <script> import Calendar from './Calendar.vue' export default { components: { Calendar }, props: { value: { type: String, default: '' } }, data () { return { date: new Date(), show: false } }, computed: { dateString () { return this.value || '' } }, methods: { handleChange (event) { const dateString = event.target.value.trim() if (dateString) { const date = new Date(dateString) if (!isNaN(date.getTime())) { this.date = date } } this.$emit('input', dateString) }, showCalendar () { this.show = true }, updateDate (date) { this.date = date this.show = false this.$emit('input', this.date.toISOString().slice(0, 10)) } } } </script>
可以看到,这个组件包含一个输入框和一个表示日历的 SVG 图标。用户点击 SVG 图标时,将会显示一个日历组件。在日历组件中选择日期后,日期范围选择器将更新数据,并将日期字符串传递到父组件中。
- 日历组件的核心 - 日历显示和交互
最后,让我们来实现一个日历组件。由于我们的目标是实现一个日期范围选择器,因此我们将仅实现日期选择,并将禁用时间选择。我们将使用 HTML 的 table 元素来构建日历,使用 CSS 来实现样式。代码如下:
<template> <div class="calendar"> <div class="calendar-header"> <button class="calendar-btn" @click.prevent="prevMonth"><</button> <span class="calendar-month">{{month}} {{year}}</span> <button class="calendar-btn" @click.prevent="nextMonth">></button> </div> <table> <thead> <tr> <th>Sun</th> <th>Mon</th> <th>Tue</th> <th>Wed</th> <th>Thu</th> <th>Fri</th> <th>Sat</th> </tr> </thead> <tbody> <tr v-for="week in weeks" :key="week"> <td v-for="date in week" :key="date" @click.prevent="updateDate(date)"> <div :class="{ 'calendar-date': true, 'calendar-date--selected': isDateSelected(date), 'calendar-date--disabled': isDateDisabled(date) }">{{date.getDate()}}</div> </td> </tr> </tbody> </table> </div> </template> <script> export default { props: { date: Date }, data () { return { year: this.date.getFullYear(), month: this.date.toLocaleString('default', { month: 'long' }), selectedDate: this.date } }, computed: { weeks () { const weeks = [] const firstDayOfMonth = new Date(this.year, this.date.getMonth(), 1) const lastDayOfMonth = new Date(this.year, this.date.getMonth() + 1, 0) const daysInMonth = lastDayOfMonth.getDate() const firstDayOfWeek = firstDayOfMonth.getDay() let week = [] for (let i = 0; i < firstDayOfWeek; i++) { week.push(new Date(this.year, this.date.getMonth(), i - firstDayOfWeek + 1)) } for (let i = 1; i <= daysInMonth; i++) { week.push(new Date(this.year, this.date.getMonth(), i)) if (week.length === 7) { weeks.push(week) week = [] } } if (week.length > 0) { for (let i = week.length; i < 7; i++) { week.push(new Date(this.year, this.date.getMonth() + 1, i - firstDayOfWeek + 1)) } weeks.push(week) } return weeks } }, methods: { prevMonth () { if (this.date.getMonth() === 0) { this.year-- this.month = 'December' } else { this.month = this.date.toLocaleString('default', { month: 'long', monthIndex: 'numeric' }) } this.date.setMonth(this.date.getMonth() - 1) }, nextMonth () { if (this.date.getMonth() === 11) { this.year++ this.month = 'January' } else { this.month = this.date.toLocaleString('default', { month: 'long' }) } this.date.setMonth(this.date.getMonth() + 1) }, isDateSelected (date) { return date.toDateString() === this.selectedDate.toDateString() }, isDateDisabled (date) { return date.getMonth() !== this.date.getMonth() }, updateDate (date) { if (!this.isDateDisabled(date)) { this.selectedDate = date this.$emit('change', date) } } } } </script>
可以看到,这段代码包含一个计算属性 weeks,它是一个数组,每个数组元素代表一个星期。对于每个星期,我们使用 v-for 指令来构建日期单元格。我们通过 isDateSelected 和 isDateDisabled 方法来确定日期是否被选择或被禁用。同时,我们使用 updateDate 方法来更新日期并通知父组件这个事件。
至此,我们已经完成了 Vue.js 中的日期范围选择器组件。这个组件支持语言环境并允许用户选择日期范围,可以方便地应用于各种应用程序中。

vue中props可以传递函数;vue中可以将字符串、数组、数字和对象作为props传递,props主要用于组件的传值,目的为了接收外面传过来的数据,语法为“export default {methods: {myFunction() {// ...}}};”。

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
