vue 组件 pc 模态


介绍

vlayer 一款融合Alert|Dialog|Modal|Message|Notify|Popover|Toast|ActionSheet等众多功能的桌面端弹出框组件。在设计开发之初,参考借鉴了Layer弹层插件、antd及iView等组件库。


快速开始

在main.js中引入弹窗组件。

import VLayer from './components/vlayer';
Vue.use(VLayer);

提供了标签式函数式2种可供选择的调用方式。

<v-layer
v-model="isConfirm"
title="标题内容"
content="<div style='color:#06f;padding:15px;'>弹窗内容信息!</div>"
xclose
z-index="2002"
lockScroll="false"
resize
dragOut
:btns="[
{text: '取消', click: () => isConfirm=false},
{text: '确定', style: 'color:#f90;', click: handleFn},
]"
/>

由于vlayer挂载了全局函数,支持函数式写法。

let $el = this.$vlayer({
title: '标题内容',
content: '<div style='color:#06f;padding:15px;'>弹窗内容信息!</div>',
xclose: true,
zIndex: 2002,
lockScroll: false,
resize: true,
dragOut: true,
btns: [
{text: '取消', click: () => { $el.close(); }},
{text: '确定', click: () => this.handleFn()},
]
});

</script>

默认是标题区可以拖拽的,当然也可以自定义拖拽元素,只需设置 drag: '#xxx'  或者设置drag: false 来禁止弹窗拖拽功能。

当设置 dragOut: true 窗体可以拖拽到浏览器外部。

当使用popover弹窗,需要传入follow: '#xxxx' 定位元素。

let $follow = this.$vlayer.popover({
follow: '#popover',
icon: 'warning',
content: '这是一段内容确定删除吗?',
time: null,
xclose: false,
btns: [
{text: 'no', click: () => { $follow.close(); }},
{text: 'yes', click: () => this.handleXXX()},
],
onClose: function() {
this.$vlayer.message({content: 'success closed', icon: 'success'})
}
});

另外还支持自定义弹窗显示位置,默认是auto居中['150px','100px'] | t | r | b | l | lt | rt | lb | rb

<!-- 自定义弹窗位置 -->
<v-layer v-model="showPosition" xclose maximize drag=".dragImg" :position="rb">
<img class="dragImg" src="xxx.jpg" />
</v-layer>

当需要一打开弹窗就全屏,只需配置fullscreen:true即可。
