js to get the absolute path to upload file

In html

 <input type="file" id="importFile" /> <input type="button" onclick="upload()"/><script>function upload() { var filename = document.getElementById("importFile").value; // The filename at this time is not the value in the importFile box alert(filename);}</script>

As in the above code, after selecting the file using the file upload dialog box, if you select the "D://temp/file/test.txt" file, alert(filename) is "C://fakepath/test.txt" why? What should I do if I want to get the original file path and file name? Thank you in advance.

 <input type="file" name="blogrollimage" onchange="setBlogrollImageName(this)" txlFillIn="isNotNull"><script type="text/javascript">function setBlogrollImageName(basicfile){document.getElementById("blogrollimagename").value=basicfile.value;}</script>

When input, add onchange="setBlogrollImageName(this)" and add this section of js to the page!

Thanks to doop1120 for its reply.

I did what you said, but the result was the same. If "D://temp/file/test.txt" is selected, document.getElementById("blogrollimagename").value=basicfile.value;

The value obtained in this way is still document.getElementById("blogrollimagename").value=C://fakepath/test.txt, not what I want D://temp/file/test.txt

The reason for D://temp/file/ is the issue of ie browser security settings

Steps to resolve this issue:

Open ie browser --> internet options --> security --> custom level --> others --> enable "Show file directory path when uploading files to server"

After confirmation, just run again
