How to use jQuery to get the current value of a fi

问题:

From what I've ready you should be able to use the 'value' property of a file input field to get the currently set path of that field. But when I do this:

 $('#fileinput').value()

I get 'undefined'. The ID of the field is set to "fileinput" I'm sure. Does anyone have any thoughts on why this might not be working for me?

And by the way, this works:

var d = document.getElementById('AttachmentFile');
alert(d.value);

So I guess this has something to do with the way jQuery works that I don't fully understand.

Thanks!

回答1:

You need to use val rather than value.

$("#fileinput").val();

回答2:

In Chrome 8 the path is always 'C:\fakepath\' with the correct file name.

回答3:

its not .val() if you want to get file /home/user/default.png it will get with .val() just default.png

回答4:

I don't think there is any real legitimate way to access this via the DOM. It would be a security risk that browsers have of late locked down on to prevent drive-by uploads.

回答5:

I think it should be

 $('#fileinput').val();

回答6:

Jquery works differently in IE and other browsers. You can access the last file name by using

alert($('input').attr('value'));

In IE the above alert will give the complete path but in other browsers it will give only the file name.

回答7:

Could you also do

$(input[type=file]).val()

回答8:

I've tried this and it works:

 yourelement.next().val();

yourelement could be:

$('#elementIdName').next().val();

good luck!
