由于官方API提供的显示模态弹窗,只能简单地显示文字内容,不能对对话框内容进行自定义,欠缺灵活性,所以自己从模态弹窗的原理角度来实现了自定义的模态对话框。
index.wxml代码:
弹窗
<view class="modal-mask" bindtap="hideModal" catchtouchmove="preventTouchMove" wx:if="{{showModal}}"></view>
<view class="modal-dialog" wx:if="{{showModal}}">
<view class="modal-title">添加数量</view>
<view class="modal-content">
<view class="modal-input">
<input placeholder-class="input-holder" type="number" maxlength="10" bindinput="inputChange" class="input" placeholder="请输入数量"></input>
</view>
</view>
<view class="modal-footer">
<view class="btn-cancel" bindtap="onCancel" data-status="cancel">取消</view>
<view class="btn-confirm" bindtap="onConfirm" data-status="confirm">确定</view>
</view>
</view>
index.wxss样式代码:
/**index.wxss**/ .show-btn { margin-top: 100rpx; color: #22cc22; } .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-dialog { width: 540rpx; overflow: hidden; position: fixed; top: 50%; left: 0; z-index: 9999; background: #f9f9f9; margin: -180rpx 105rpx; border-radius: 36rpx; } .modal-title { padding-top: 50rpx; font-size: 36rpx; color: #030303; text-align: center; } .modal-content { padding: 50rpx 32rpx; } .modal-input { display: flex; background: #fff; border: 2rpx solid #ddd; border-radius: 4rpx; font-size: 28rpx; } .input { width: 100%; height: 82rpx; font-size: 28rpx; line-height: 28rpx; padding: 0 20rpx; box-sizing: border-box; color: #333; } input-holder { color: #666; font-size: 28rpx; } .modal-footer { display: flex; flex-direction: row; height: 86rpx; border-top: 1px solid #dedede; font-size: 34rpx; line-height: 86rpx; } .btn-cancel { width: 50%; color: #666; text-align: center; border-right: 1px solid #dedede; } .btn-confirm { width: 50%; color: #ec5300; text-align: center; }
index.js代码如下:
/index.js
//获取应用实例 var app = getApp() Page({ data: { showModal: false, }, onLoad: function () { }, /** * 弹窗 */ showDialogBtn: function () { this.setData({ showModal: true }) }, /** * 弹出框蒙层截断touchmove事件 */ preventTouchMove: function () { }, /** * 隐藏模态对话框 */ hideModal: function () { this.setData({ showModal: false }); }, /** * 对话框取消按钮点击事件 */ onCancel: function () { this.hideModal(); }, /** * 对话框确认按钮点击事件 */ onConfirm: function () { this.hideModal(); } })
