基于Vue.js PC桌面端弹出框组件|vue自定义弹层组件|vue模态框

vue.js构建的轻量级PC网页端交互式弹层组件VLayer。

前段时间有分享过一个vue移动端弹窗组件,今天给大家分享一个最近开发的vue pc端弹出层组件。

VLayer 一款集Alert、Dialog、Message、Notification、ActionSheet、Toast、Popover、Popconfirm等众多功能于一身的轻量级pc弹层组件。通过精巧的逻辑、布局解决复杂的对话框功能,为你呈现多样化弹出框效果!

VLayer 在设计开发之初借鉴了业界有名的Layer弹窗、Element-UI、iView等组件化设计思想。

  • 提供了2种调用方式(标签式 | 函数式)
  • 12+弹窗类型(toast、footer、actionsheet、actionsheetPicker、android/ios、contextmenu、drawer、iframe、message、notify、popover)
  • 内置7种弹窗动画(scaleIn | fadeIn | footer | fadeInUp | fadeInDown | fadeInLeft | fadeInRight)

◆ 引入组件

在main.js中引入vlayer组件。

 import VLayer from './components/vlayer' 

 Vue.use(VLayer) 

vlayer支持标签式函数式两种调用方式。

  • 标签式写法
<v-layer 
    v-model="showConfirm"
    title="标题内容"
    content="<div style='color:#00e0a1;padding:20px;'>这里是内容信息!</div>"
    xclose
    z-index="2001"
    lockScroll="false"
    resize
    dragOut
    :btns="[
        {text: '关闭', click: () => showConfirm=false},
        {text: '确认', style: 'color:#f90;', click: handleXXX},
    ]"
/>
  • 函数式写法

vlayer同样支持函数式写法  this.$vlayer({...})  支持30+中参数灵活配置。

注意:当使用类型为message | notify | popover弹窗时候,调用方式只能是函数式 this.$vlayer.message({...})  this.$vlayer.notify({...})  this.$vlayer.popover({...}) 

let $vlayero = this.$vlayer({
    title: '标题内容',
    content: '<div style='color:#00e0a1;padding:20px;'>这里是内容信息!</div>', 
    xclose: true,
    zIndex: 2001,
    lockScroll: false,
    resize: true,
    dragOut: true,
    btns: [
        {text: '关闭', click: () => { $vlayero.close(); }},
        {text: '确认', click: () => this.handleXXX()},
    ]
});

          typeof btn.click === 'function' && btn.click(e)
        }
      },
    },
  }
</script>

dom.js中是一些常用的函数。当弹窗出现,滚动条隐藏,避免出现页面移位。

getScrollBarSize: function() {
    if (scrollBarWidth !== undefined) return scrollBarWidth;

    const outer = document.createElement('div');
    outer.style.visibility = 'hidden';
    outer.style.width = '100px';
    outer.style.position = 'absolute';
    outer.style.top = '-9999px';
    document.body.appendChild(outer);

    const widthNoScroll = outer.offsetWidth;
    outer.style.overflow = 'scroll';

    const inner = document.createElement('div');
    inner.style.width = '100%';
    outer.appendChild(inner);

    const widthWithScroll = inner.offsetWidth;
    outer.parentNode.removeChild(outer);
    scrollBarWidth = widthNoScroll - widthWithScroll;

    return scrollBarWidth;
},

vlayer弹窗通过 Vue.extend 扩展函数实现函数式调用。

import Vue from 'vue';
import VueLayer from './vlayer.vue';

let VLayerConstructor = Vue.extend(VueLayer);

let $instance;
let _getInstance = props => {
    return new VLayerConstructor(props)
}

let VLayer = function(options = {}) {
    // ...
}

/**
 * Message 消息提示
 * @param {Object} options 
 */
VLayer.message = function(options) {
    typeof options == 'string' && (options = { content: options });
    return VLayer({
        icon: 'info', anim: 'fadeInUp', position: 't', lockScroll: false, shade: false, time: 2, layerStyle: 'margin-top:15px;',
        ...options,
        title: null, type: 'message'
    })
}

/**
 * Notification 通知提醒
 * @param {Object} options 
 */
VLayer.notify = function(options) {
    typeof options == 'string' && (options = { content: options });
    return VLayer({
        anim: 'fadeInRight', position: 'rt', lockScroll: false, shade: false, xclose: true, time: 4.5, layerStyle: 'margin:20px 0 0 -20px;',
        ...options,
        type: 'notify'
    })
}

/**
 * Popover 弹出框 | Popconfirm 气泡确认框
 * @param {Object} options 
 */
VLayer.popover = function(options) {
    return VLayer({
        anim: 'fadeIn', lockScroll: false, shade: false, xclose: true,
        ...options,
        type: 'popover'
    })
}

VLayer.install = () => {
    Vue.prototype['$vlayer'] = VLayer;
    Vue.component('v-layer', VueLayer);
}

export default VLayer;

默认标题区可以拖拽,也可以自定义拖拽抓手。设置 drag: '#xxx',或者 drag: false 禁止拖拽。

<!-- 拖拽弹窗 -->
<v-layer 
    v-model="showDragable" 
    title="拖放弹窗" 
    xclose 
    maximize 
    :area="['', '580px']" 
    drag="#dragGuesture" 
    dragOut
>
    <div slot="content">
        <p id="dragGuesture" style="padding:30px;">
            <span style="background:#ff0;color:#00e0a1;">我是自定义拖拽抓手 drag:'#dragGuesture' <br>拖动我试一试!<br>
            <em style="color:red;">设置drag:false可禁止拖拽!</em><br>
            <em style="color:red;">设置dragOut:true可拖拽到窗口外!</em>
            </span>
        </p>
        <img @click="handleInfo" src="xxx.jpg" style="max-width:100%;" />
    </div>
</v-layer>
  • message 信息框

<!-- 普通提示 -->
this.$vlayer.message('这是一条提示信息');

<!-- 成功提示 -->
this.$vlayer.message({content: '这是一条成功的提示', icon: 'success'});

<!-- 错误提示(自定义背景) -->
this.$vlayer.message({content: ' 这是一条错误的提示', icon: 'error', layerStyle: 'background:#ffefe6;color:#ff3838;margin-top:15px;'});
  • notification 通知框

<!-- 成功通知 -->
this.$vlayer.notify({title: '成功', content: '这是一条成功的提示', icon: 'success'});
  • popover / popconfirm 气泡框

<!-- 使用方法和上面差不多,只不过需要加上follow定位元素 -->
let $fw = this.$vlayer.popover({
    follow: '#popover4',
    icon: 'warning',
    content: '这是一段内容确定删除吗?', 
    time: null, 
    xclose: false,
    btns: [
        {text: 'no', click: () => { $fw.close(); }},
        {text: 'yes', click: () => this.handleXXX()},
    ],
    onClose: function() {
        this.$vlayer.message({content: 'success closed', icon: 'success'})
    }
});

另外还支持iframe弹窗类型,设置 type: 'iframe',content传入网址即可。

<!-- iframe弹窗 -->
<v-layer
    title="iframe弹窗"
    content="https://cn.vuejs.org/"
    v-model="showIframe"
    type="iframe"
    lock-scroll="false"
    xclose
    maximize
    resize
    :area="['915px', '595px']"  
/>

okay,以上就是基于vue.js实现pc端弹窗的一些分享,希望对大家有所帮助!💪💪
