Remove "All Files" option from uploader [duplicate]

Question

I am using

< input type="file" >

to upload files.

To upload only selective files i am using "accept". So dialog box contains my selected types of files extension. But there is an option of "All Files" which i do not want there.

How can I remove this option?

Answer 1

The best you can do (natively) is to check which file was selected :

<input   id="uploadFile" type="file"  onchange="FileSelected(this)"  />

Script :

function FileSelected(sender)
{
    if (check(sender.value)) //check is you function to check extension 
    {...}
    else
    {...}
}

Sample code : ( check only jpg)

Edit

in chrome . ie10 you can do :

<!-- (IE 10+, Chrome) -->
<input type="file" accept=".xls,.xlsx">

With FF :

<!-- (IE 10+, Chrome, Firefox) -->
<input type="file"
 accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel" />
