【转】H5调用照相机等设备
作者:互联网
使用input标签 type值为file,可以调用系统默认的照相机、相册、摄像机、录音功能:
<input type="file" accept="image/*" capture="camera">
<input type="file" accept="video/*" capture="camcorder">
<input type="file" accept="audio/*" capture="microphone">
属性 | 说明 |
---|---|
accept | 打开的系统文件目录 |
capture | 系统所捕获的默认设备,camera:照相机;camcorder:摄像机;microphone:录音; |
multiple | 多选,multiple优先级高于capture,<input type="file" accept="image/*" multiple> |
测试发现存在很多兼容性问题,下面将测试出的部分结果列出:
设备 | 安卓 | IOS |
---|---|---|
camera | 相机、图库、文件管理器等混合选择项 | 相机 |
camcorder | 摄像机 | 摄像机 |
microphone | 录音 | 相机 |
