input file check box, when about 2500 files are selected, the total size is about 25.7m, so the onChange event is not triggered, so there is no upload
.what I want to know is whether there is an upper limit on the number of input file checkboxes and where to find them. I searched the Internet for a long time but couldn"t find it
. windows,
browsers should use the File Dialog function provided by the windows system.
this API parameter contains a buffer to save the file name. Your limitation should be caused by the size of this buffer.
as to how big the buffer is, it can only be estimated in the source code of each browser (the probability is different)
refer to https://bbs.csdn.net/topics/1...
The GetOpenFileName and GetSaveFileName functions return FALSE if the buffer is too small to contain the file information. return FALSE so you didn't get the onchange
