微信小程序自定义弹出窗代替wx.showModal

这篇文章讲解一下微信小程序自定义弹出窗，模拟wx.showModal的一个简单实现，来解决wx.showModal无法换行，无法自定义的问题

首先看一下样式结果

好，直接上代码

wxml代码

<button catchtap="show">显示</button>

<view class="sjn-modal {{showModal?'show':''}}">
	<view class="sjn-dialog">
		<view class="sjn-dialog-title">提示</view>
		<text>1、这是文本
			1、这是文本
			1、这是文本
			1、这是文本
			1、这是文本
			1、这是文本
		</text>
		<view class="sjn-btn" catchtap="close">
			确定
		</view>
	</view>
</view>

wxss代码

.sjn-modal {
	position: fixed;
	top: 0;
	right: 0;
	bottom: 0;
	left: 0;
	z-index: 1110;
	opacity: 0;
	outline: 0;
	text-align: center;
	-ms-transform: scale(1.185);
	transform: scale(1.185);
	backface-visibility: hidden;
	perspective: 2000rpx;
	background: rgba(0, 0, 0, 0.6);
	transition: all 0.3s ease-in-out 0s;
	pointer-events: none;
}

.sjn-modal::before {
	content: "\200B";
	display: inline-block;
	height: 100%;
	vertical-align: middle;
}

.sjn-modal.show {
	opacity: 1;
	transition-duration: 0.3s;
	-ms-transform: scale(1);
	transform: scale(1);
	overflow-x: hidden;
	overflow-y: auto;
	pointer-events: auto;
}

.sjn-dialog {
	position: relative;
	display: inline-block;
	vertical-align: middle;
	margin-left: auto;
	margin-right: auto;
	width: 680rpx;
	max-width: 100%;
	background-color: #f8f8f8;
	border-radius: 10rpx;
	overflow: hidden;
}

.sjn-btn {
	position: relative;
	align-items: center;
	min-height: 100rpx;
	background-color: #fff;
	text-align: center;
	line-height: 100rpx;
	color: green;
}

.sjn-dialog-title{
	text-align: center;
	background-color: #fff;
	font-weight: bold;
	line-height: 100rpx;
}

js中的事件代码

Page({

	/**
	 * 页面的初始数据
	 */
	data: {
		showModal:false
	},

	/**
	 * 生命周期函数--监听页面加载
	 */
	onLoad: function (options) {

	},
        //隐藏
	close:function()
	{
		this.setData({
			showModal:false
		})
	},
        //显示
	show:function(){
		this.setData({
			showModal:true
		})
	}
})
