回答我自己的问题...... [英] answer my own question...

问题描述

所以...我的代码没有错误，我只是使用你的（在某些用途上不坏）没有成功（但你选择判断这么快，如此强大......），但是出于某些保护原因和/或特殊性，有时一些其他代码可以工作（解决方案编号3），然后我来自rails 4框架与webrick服务器（适用于Firefox 25和Chrome 29，不适用于Safari）：

 function readURL（）{
  var  input = document.getElementById（'  FilePhoto'）; 
  var  fReader =  new  FileReader（）; 
 fReader.readAsDataURL（input.files [ 0 ]）; 
 fReader.onloadend = function（ event ）{
  var  img = document。 getElementById（  blah）; 
 img.src =  event  .target.result; 
} 
} 

（无需函数事件调用...来自文件celetion字段的onchange选项正常，而且，不需要从事件调用的函数varthis

所以...我希望你的团队中的其他一些人能够说你慢慢去判断别人这么快，如此强烈，并试着回到学校去了解如何构建一个问题...... （等等......真是太遗憾......）。

如果你不认识男人，就说：对不起，我不知道。

解决方案

出于某些保护原因和/或特殊性，有时其他一些代码可以用来做（解决方案编号3），然后我从带有webrick服务器的rails 4框架（适用于firefox 25和chrome 29，而不是on Safari）：

 function readURL（）{
  var  input = document.getElementById（'  FilePhoto'）; 
  var  fReader =  new  FileReader（）; 
 fReader.readAsDataURL（input.files [ 0 ]）; 
 fReader.onloadend = function（ event ）{
  var  img = document。 getElementById（  blah）; 
 img.src =  event  .target.result; 
} 
} 

（不需要函数事件调用...来自文件celetion字段的onchange选项没问题，而且，从事件中调用的函数不需要varthis

so... my code has no error, i just use yours (who is not bad on some use) without success (but you choose to judge so quick, so strong...), but for some protect reason and/or specificities, sometimes some other codes can works for do it (solution number 3), and then i'm from rails 4 framework with webrick server (works on firefox 25 and chrome 29, not on Safari):

function readURL() {
  var input = document.getElementById('FilePhoto');
  var fReader = new FileReader();
  fReader.readAsDataURL(input.files[0]);
  fReader.onloadend = function(event){
  var img = document.getElementById("blah");
  img.src = event.target.result;
  }
}

(no need function event call... "onchange" option from file celetion field is ok, and also, no need var "this" on function called from event)

so... i hope some other peoples from your team could said you to go slowly before judge other people so quickly and so strongly, and try to go back school for understand how is construct a question... (and so... it is really a shame...).
If you don't know guys, just said: I'm sorry, i don't know.
