JavaScript没有结构。 所以我可以在javascript中创建像struct abc这样的GLOBAL对象吗。 JavaScript是一种基于对象的动态语言,不使用C语言中的struct概念。 根据您的要求,您可以使用- /* definition of an Object */ var xyz = function(age,name){ this.age = age; this.name = name; return this; }; /* composition */ var abc = { start:'', end:'', length:'', xyz_pseudo_array: [] }; //push data inside the **xyz_pseudo_array** as and when needed, without having to worry about size- abc.xyz_pseudo_array.push(new xyz(25,"Bill Gates"));
