利用javascript将开放方言箱限制在某些档案中
原标题:Restricting open dialog box to certain files using javascript

在上载照片和录像时,公开的辩证箱应缺省,以提出相关内容。 e. 在超载图像时,它只能显示延伸文件......jpeg、jpg、gif、png、bmp等。 同录像一样。

感谢。

You(可能出于安全原因)可以做到这一点。 “公开档案”的方言由浏览器<input category=“file”>控制而不是由《联合材料法典》处理。

如果绝对有必要的话,考虑的是 Java或闪电式高压器,那么你对国际交易日志的控制就大得多。
