输入元素的“接受”属性不起作用 [英] 'Accept' attribute of input element is not working

问题描述

我在html中遇到了一个浏览文件对话框控制标记，标记为

I came across a browse file dialog-control tag in html and the tag was

<input id="myfile" name="myfile" type="file" accept="application/pdf"/>

，但是 accept属性似乎没有任何作用。我正在使用Internet Explorer 8。

but the 'accept' attribute doesn't seems to have any effect. I am using Internet Explorer 8.

推荐答案

根据w3schools（ http://www.w3schools.com/TAGS/att_input_accept.asp ），任何主流浏览器均未正确支持 accept属性。文件浏览器对话框中的过滤器将不起作用。

according to the w3schools (http://www.w3schools.com/TAGS/att_input_accept.asp), the 'accept' attribute is not properly supported by any of the major browsers. The filter inside the file browser dialog will not work.

您可以在表单onsubmit事件上使用javascript验证来验证文件类型是否正确，否则返回false。

You could use a javascript validation on the form onsubmit event to verify if the file type is correct, returning false otherwise.
