Question

我正在更新上传文件的脚本，然后在继续上传循环之前从响应中提取数据。

我认为问题是当文件上传并且我正在运行提交表单的javascript（或.click提交）时，Postback会在新选项卡中返回。我相信在等待从提交的页面回发时，watir正在挂起并变得没有响应，但它已经在新标签中打开了（此脚本的旧版本经常使用经典watir的click_no_wait）。脚本超时并且我失去了对窗口的附件，即使我救援超时也无法与浏览器交互。

几天来一直试图解决这个问题。运行一个简单的Ruby行

  p "Submitting..."
  @b.execute_script("javascript:UpldFil();")

以下是已经在响应页面上的此提交的调试：

"Submitting..."
-> POST session/11324ae12918982202d689070e60ee2c/execute
>>> {"script":"javascript:UpldFil();","args":[]}
> {"Content-Length"=>"44", "Content-Type"=>"application/json; charset=utf-8", "Accept"=>"application/json"}
Exception `#<Class:0x5f11b18>' at C:/Ruby187/lib/ruby/1.8/timeout.rb:64 - execution expired
Exception `Timeout::Error' at C:/Ruby187/lib/ruby/1.8/timeout.rb:79 - execution expired

功能UpldFil（）

function UpldFil() {
var windowName = "Submission"; 
var fm = document.forms[0];

if (fm.FilNam.value == "") {
alert("Please select a file for submission");
return false;
 }
}   
document.forms[0].submit();

使用： Ruby 1.8.7（2013-06-27 patchlevel 374）[i386-mingw32]，的Watir-webdriver的-0.6.1， Chrome 19

我目前无法更新其中的任何内容，因为它们太多的家属也需要更新。更新和此问题的计划是升级的第1阶段。

在最新的ruby / chrome / webdriver环境中本地运行。这是调试：

继续调试以吐出20-30个ChildProcess行，浏览器崩溃并关闭。
