PhantomJS removeTree

removeTree方法用于删除给定文件夹中的所有文件和文件夹，最后删除该文件夹本身。如果在执行此过程中出现任何错误，它将抛出一个错误-“无法删除目录树路径”并挂起执行。

语法

它的语法如下所示 –

fs.removeTree(foldertodelete)

示例

下面的示例演示了 removeTree 方法的工作原理。

var fs = require('fs'); 
var system = require('system'); 
var path = system.args[1]; 
console.log("Directory present : "+fs.isDirectory(path)); 

var a = fs.list(path); 
console.log("Listing the contents from the directory : " + JSON.stringify(a)); 
console.log("Removing directory "+path);  

var rd = fs.removeTree(path); 
console.log("Directory present "+fs.isDirectory(path)); 
phantom.exit();

以上程序生成以下输出。

Directory present : true 
Listing the contents from the directory : [".","..","examples","newfiles"] 
Removing directory removetree 
Directory present false
