本文实例为大家分享了小程序自定义弹框的具体代码，供大家参考，具体内容如下
1、页面简单布局
<button bindtap='ElasticFrameClick'>弹框</button>
<view class="modal-mask" bindtap="hideModal" wx:if="{{showModal}}"></view>
<view wx:if="{{showModal}}">
<view class="modal-content">
<view class='modal_title'>添加备注</view>
<view class='modal_textarea'>
<textarea placeholder='备注' maxlength='-1'></textarea>
</view>
<view class='btn'bindtap='hideModal'>保存</view>
</view>
</view>2、样式设置
.modal-mask {
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
background: #000;
opacity: 0.5;
overflow: hidden;
z-index: 9000;
color: #fff;
}
.modal-content {
position: fixed;
top: 120rpx;
left: 75rpx;
z-index: 9500;
width: 600rpx;
height: 720rpx;
overflow: hidden;
background: #fff;
border-radius: 20rpx;
}
.modal_title {
height: 96rpx;
width: 100%;
line-height: 96rpx;
border-top-right-radius: 20rpx;
border-top-left-radius: 20rpx;
background-color: #5a94ff;
color: #fff;
text-align: center;
}
.modal_textarea {
height: 395rpx;
width: calc(100% - 40rpx);
margin: 20rpx;
}
.modal_textarea textarea {
height: 100%;
width: 100%;
}
.btn{
height: 70rpx;
width: 390rpx;
background-color: #5a94ff;
color: #fff;
text-align: center;
line-height: 70rpx;
border-radius: 50rpx;
margin: 0 auto;
margin-top: 40rpx;
}3、js控制
Page({
data: {
showModal: false,
},
onLoad: function(options) {
},
ElasticFrameClick: function() {
this.setData({
showModal: true
})
},
toShowModal(e) {
this.setData({
showModal: true
})
},
// 隐藏弹框
hideModal() {
this.setData({
showModal: false
});
},
onReady: function() {
},
onShow: function() {
},
onHide: function() {
},
onUnload: function() {
},
onPullDownRefresh: function() {
},
onReachBottom: function() {
},
onShareAppMessage: function() {

})4、页面呈现
