上传文件 获取路径

 <input name="fdxml" id="upload" type="file" />

1一开始获取C:fakepathdoc.xml 实际路径：D：xmldoc.xml

设置浏览器获取到实际路径：interneter选项--安全-自定义级别—启用-将文件上传时包含本地路径

区分浏览器

  if (obj) {                 var file_up = document.getElementById('upload');                    

//ie                 if (window.navigator.userAgent.indexOf("MSIE") >= 1) {                                         

file_up.select();

                        var realpath = document.selection.createRange().text;

                                      }                    

//firefox                     else if (window.navigator.userAgent.indexOf("Firefox") >= 1) {                     

    if (file_up.files) {                          

   return file_up.files.item(0).getAsDataURL();                        

}                         return file_up.value;            

         }                             

      }
