------Solution--------------------
You're giving too little information.
------Solution--------------------
Judging by my years of experience ... It should be JS problem.
Your 2 platform browser is consistent. Whether the browser is the same.
var f_content = Form.fileToUpload.value;
The form can be used directly? I feel the problem of Jane writing

And then look at the JS problem or the PHP problem.
Cancel JS to determine the test can be uploaded successfully. AJAX trigger alert (1) Ajax execution successful return at alert (2)



------Solution--------------------
Separate test to solve the problem
------Solution--------------------
It's probably a matter of case.
------Solution--------------------
To complete the test individually:
1, judge whether JS gets the form object is successful;
2, to determine the feedback of the results of the submission, such as the form does not submit files, only post data, to determine the PHP back end of the post global array output;
3, the use of the removal of JS after the form submitted to see if the success;
4, use to remove JS after the file upload, to see if the success; (Ensure that the corresponding directory on the Linux server has write permissions)
