执行了js方法外面的alert可以弹刚看到有个js undefined 以为大小写呢还没找到问题
凭借我多年的经验判断...应该是JS问题.
你2个平台浏览器是否一致..浏览器是否一样.
var f_content = form.fileToUpload.value;
form能直接用?我感觉这种简写出的问题然后在看是JS问题还是PHP问题..
取消JS判断试试可否上传成功.ajax触发处alert(1) ajax执行成功返回处alert(2)
单独来完成测试：
1、判断js获取表单对象是否成功；
2、判断提交结果的反馈，比如表单中不提交文件，只POST数据，判断PHP后端的POST全局数组的输出；
3、使用去掉JS之后的表单提交，看是否成功；
4、使用去掉JS之后的文件上传，看是否成功；（确保linux服务器上对应的目录有写权限）
这个var f_content = form.fileToUpload.value; 改了
现在还报错是：Uncaught SyntaxError: Unexpected end of input
chrome ie 都有...
解决了因为返回json类型不会返回具体错误所以js改jquery取值后是没问题（win下本来就没问题的），查到最后是因为运维的没建立对应表插不进报错。建表后一切正常了，谢谢大家~~
