JavaScript/jQuery Tree View - Drag & Drop for Hierarchical Data Structure This sample app demonstrates node drag and drop operations within DevExtreme JavaScript TreeView when using a hierarchical data structure. You can reorder nodes within a single tree view or drag and drop nodes ...
在JavaScript中,可以将JSON映射为树(tree)的数据结构。树是一种非线性的数据结构,由节点和边组成,节点之间存在层次关系。在JSON中,可以使用对象和数组来表示树的节点和子节点。 将JSON映射为树可以通过递归的方式实现。首先,我们需要解析JSON字符串,将其转换为JavaScript对象。然后,遍历对象的属性,判断属性值的类型。
