5.拓展知識：
怎么樣調(diào)取用戶手機照相機] 來源：(http://www.cnblogs.com/yw-ah/p/6112677.html)
如下：
1）
使用input：file標簽, 去調(diào)用系統(tǒng)默認相機，攝像，錄音功能，其實是有個capture屬性，直接說明需要調(diào)用什么功能
<input type="file" accept="image/*" capture="camera">
<input type="file" accept="video/*" capture="camcorder">
<input type="file" accept="audio/*" capture="microphone">
capture表示，可以捕獲到系統(tǒng)默認的設(shè)備，比如：camera--照相機；camcorder--攝像機；microphone--錄音。
accept表示，直接打開系統(tǒng)文件目錄。
2）
input:file標簽還支持一個multiple屬性，表示可以支持多選，如：
<input type="file" accept="image/*" multiple>
加上這個multiple后，capture就沒啥用了，因為multiple是專門用來支持多選的。
