然后准备一个待语法高亮的示例代码example.js,这里你也可以用自己的代码试试: // 定义一个变量letgreeting='Hello, World!';/** * 打印问候语 * @param{string}message - 要打印的消息 */functionprintGreeting(message){console.log(message);}// 定义一个类 ...
getNodesData(argWanted, conditions = {}, format = false)Customizable function that returns nodes Get the tree instance If you want to call any tree method, you need to get the instance. To get the tree instance you just need to be in the vue instance and usethis.$refs['my-tree-ref'...
The callback function takes the directory item (has path, name, size, and extension) and an instance ofnode pathand an instance ofnode FS.stats. You can also pass a callback function for directories: constPATH=require('path');constdirTree=require('directory-tree');consttree=dirTree('./tes...
As is, this implementation is vulnerable to asecond pre-image attack. Use a difference hashing function for leaves and nodes, so thatH(x) != H'(x). Also, as is, this implementation is vulnerable to a forgery attack for an unbalanced tree, where the last leaf node can be duplicated to...
