本文主要是介绍微信小程序WeUI中half-screen-dialog底部弹窗相关问题,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
需求:
如图需要从页面底部弹出一个弹框,弹框里的内容超出最大高度时,可以滚动。
问题:
- 原生的组件关闭图标在左侧,需要通过样式改到右侧
- 原生的组件底部有footer按钮区域,需要通过样式隐藏掉
- 在弹框里使用区域滚动通过scroll-view 设置纵向滚动并给最大高度
- 设置title
- half-screen-dialog如果在子组件中引入,需要在pages父组件中的css文件里修改样式。在子组件中修改不生效
代码:
index.json
{"component": true,"usingComponents": {"compute-cart": "/components/computeCart","mp-half-screen-dialog": "weui-miniprogram/half-screen-dialog/half-screen-dialog"}
}

弹窗样式只能写在pages父组件中
/* half-screen-dialog ui组件样式只能写在pages里 */.type-dialog .weui-half-screen-dialog__ft {display: none !important;
}
.type-dialog .weui-half-screen-dialog__bd {padding-bottom: 20px;
}
.type-dialog {padding: 0;
}
.weui-half-screen-dialog__hd {padding: 0 32rpx;
}
/* 隐藏更多按钮避免关闭点击偶尔失效 */
.weui-half-screen-dialog .weui-icon-btn_more{display: none !important;
}
.weui-icon-btn_close {position: absolute;right: -680rpx;
}
.weui-half-screen-dialog__hd__main {padding-left: 0 !important;
}
