如何通过JavaScript查找或不通过远程服务器目录

Question

我在我的Ant脚本中使用JavaScript来传递运行时网络远程文件夹值作为输入。通过该值后，我发现输入文件夹路径存在与否。但我无法做到这一点。 我的代码如下。

<script language="javascript"> 
    <![CDATA[ 
     importPackage(javax.io); 
     importPackage(javax.swing); 
     importPackage(java.lang); 
     var deployment_machine = project.getProperty("var2"); 
     var deployment_machine = deployment_machine.substring(2,deployment_machine.indexOf("$")-2); 
     var optionPane = JOptionPane.showInputDialog('Deployment location for GatewayFW in ' + deployment_machine + '?', null); 
     var path = require('optionPane'); 
     if (path.existsSync("/the/path")) { 
       // ... 
      } 

     if(!fso.FolderExists(optionPane)) 
     { 
     var optionPane = JOptionPane.showInputDialog('Deployment location for GatewayFW in ?', deployment_machine); 
     } 
     else 
     { 
     project.setProperty('deploy_loc',optionPane); 
     }   
    ]]> 
    </script> 
</then> 
<else> 
    <echo message="File need to check:- ${patch.path}/${patch.name}/GatewayFW_patch.zip is not exist"/> 
</else> 

`

谁能帮我请？

<script language="javascript"> <![CDATA[ importPackage(java.io); importPackage(javax.swing); importPackage(java.lang); var deployment_machine = project.getProperty("var2"); var deployment_machine = deployment_machine.substring(2,deployment_machine.indexOf("$")-2);
do { var optionPane = JOptionPane.showInputDialog('Deployment location for GatewayFW in ' + deployment_machine + '?', null);
var dir = new File(optionPane); } while(!dir.exists()); project.setProperty('deploy_loc',optionPane); ]]> </script> 这里我们必须给文件（“文件夹路径”）分配一个JavaScript变量，就像上面的var = dir = new File（“folder path”）; 然后我们可以在路径上执行任何操作。
