tar -xvf phantomjs-1.9.7-linux-x86_64.tar.bz2

–将程序移到一个合适的位置

sudo mv phantomjs-1.9.7-linux-x86_64 /usr/local/src/phantomjs

—-创建软链接到环境变量中。这样可以直接在shell中使用phantomjs命令

sudo ln -sf /usr/local/src/phantomjs/bin/phantomjs /usr/local/bin/phantomjs

—-检查是否正常工作

phantomjs –version

如果你看到当前版本号，即表示正常工作了。

--------------------------------------------------
Windows下安装
第一步：下载了PhantomJS后，把压缩包里的文件夹解压到D盘，重命名文件夹为phantomjs，然后在windows中添加环境变量;D:\phantomjs到Path中。在这里先不用关心phantomjs文件夹下的内容。

C# to ActionScript Communication

As I said before, communication between Flash Player and its container has been made extremely easy. The new class that makes this process so easy is the ExternalInterface. We will begin in the ActionScript. First, we need to import this new class so we can use it (as2 only, in as3 it will work without the import):

import flash.external.ExternalInterface;

Next, we have to register any function we want to make available externally:

ExternalInterface.addCallback("addText", addText);

Basically, the code above will allow us to call the addText function (which I will show in a minute) from the C# application.
The addText function is as below. Basically, it takes a string input and appends it to a text box

function addText(val:String):void
{
inTxt.appendText(val + "\n"); // append text recieved from c#
}

That’s it from the ActionScript side. Now all we need to do is call the function from C#. First, I add an instance of the Flash Player ActiveX control to my form and load the SWF we created in the form’s constructor:

private AxShockwaveFlash player;
 
public DemoForm ()
{
...
player.LoadMovie(0, Application.StartupPath + "\\EITest.swf");
player.Play();
...
}

Next, all we have to do is call the externalized method when desired. In my case, it is in response to the user clicking the send button:

private void sendBtn_Click(object sender, EventArgs e)
{
player.CallFunction("" + outTxt.Text + "");
}

ActionScript to C# Communication

Again, you will need to use the ExternalInterface in the ActionScript:

function send(evt : Event):void
{
ExternalInterface.call("sendText", outTxt.text); // function to call and it's parameters
outTxt.text = ""; // reset text box
}

As you can see, I am calling a method sendText and passing the input string as a parameter. Now to receive the message in C#, we first have to subscribe to the FlashCall event. You can do this in the constructor or from the activex properties panel on events tab.

Now the call made in ActionScript will be received in the request property of the event argument. For my particular call, the XML will look like this:

<invoke name="sendText" returntype="xml">
<arguments>
<string>some text message here</string>
</arguments>
</invoke>

So now all we have to do is parse the XML in the event handler and invoke the C# function locally:

private void player_FlashCall(object sender, _IShockwaveFlashEvents_FlashCallEvent e)
{
// message is in xml format so we need to parse it
XmlDocument document = new XmlDocument();
document.LoadXml(e.request);
// get attributes to see which command flash is trying to call
XmlAttributeCollection attributes = document.FirstChild.Attributes;
String command = attributes.Item(0).InnerText;
// get parameters
XmlNodeList list = document.GetElementsByTagName("arguments");
// Interpret command
switch (command)
{
case "sendText" : resultTxt.Text = list[0].InnerText; break;
case "Some_Other_Command" : break;
}
}

即加上WorkingDir: {app}。见inno setup FAQ.

使用WebProxy类，该类空间名 using  System.net;
  
WebProxy proxyObject = new WebProxy("代理服务器IP和端口（例如：http://proxyserver:80/）",true);
WebRequest req = WebRequest.Create("http://www.contoso.com"); //使用WebRequest上网
req.Proxy = proxyObject; //设置代理

Jpxx.forceLogout()方法通过AJAX技术来强制注销用户，即调用session.invalidate()方法。

Deployment failure on Tomcat  6.x. Could not copy all resources to E:\apache-tomcat-6.0.16\webapps\HebbnWebServices. If a file is locked, you can wait until the lock times out to redeploy, or stop the server and redeploy, or manually remove the deployment at E:\apache-tomcat-6.0.16\webapps\HebbnWebServices

再次点部署按钮时就会提示如下：

Undeployment Failure could not be redeployed because it could not be completely removed in the undeployment phase. the most common cuase of this problem is attempting to redeploy while the server is running,which has locked one or more files.

to correct the deployment you will need to stop the server and then redeploy the project before restarting the server.

解决的办法就是在Eclipse中把项目中引用的jar文件重新加一遍就行了，基本原因就是以前的jar文件不存在了，但是项目信息中还有，即项目的.classpath文件中还有不存在的jar文件引用。

可以右键点项目名称，选择Properties,选择Java Build Path,选择Libraries,把所有项目中的jar都remove，然后再点"add jars"，把项目中的jar文件都加进来，再次部署就正常了。

ie7显示出来的checkbox居然是未选中的但是alert出来的却是true，而FF一切正常
后来查了半天资料说是ie显示的时候只对状态改变比较敏感
改成
var echkbox=document.createElement("input");
echkbox.setAttribute("type","checkbox");
echkbox.setAttribute("id","inputid");
echkbox.setAttribute("name","inputname");
echkbox.setAttribute("value","inputvalue");
var addhere=document.getElementById("someElementId");
addhere.appendChild(echkbox);
echkbox.setAttribute("checked","checked");
alert(document.getElementById("inputid").checked);

一切ok
radio同样是这种情况。

为了防止缓存，可以在页面的顶端添加   response.expires   =   -1    

使用java提供的方法，在jsp或者servlet中都可以   <%   response.setheader("pragma","no-cache");    
  response.setheader("cache-control","no-cache");   response.setdateheader("expires",   0);  
    %>  

使用NET在CS页面在page   load中把这句加上!  
  context.response.cache.setcacheability(httpcacheability.nocache);

使用html标记，如下面：   <head>   <meta   http-equiv="pragma"   content="no-cache">    
  <meta   http-equiv="cache-control"   content="no-cache">   <meta   http-equiv="expires"   content="0">    
  </head>
