Javascript 或 jQuery 获取Processingjs 变量？

Question

是否可以从 processingjs 传递变量 Javascript/jQuery 用于 AJAX 发送到服务器

Answer 1

当然有可能。有很多方法，其中一种方法是将您希望传递的变量附加到 window 对象。这不是唯一的解决方案，也绝对不是最优雅的解决方案，但是它确实有效。

所以像这样:

// processingjs code...
window.varIWantToPassAround = "whatever"; 

// jQuery code... 
// as long as you don't redefine the variable "varIWantToPassAround", you can reference it without referencing the window object. IE "window.varIWantToPassAround"
// but I like to be explicit so when I read my code 3 months later and go "where did *that* come from, I can see it is attached to the window object.
$("#unicorn_powerd_div").someFunctionThatGrowsMagicUnicorns(window.varIWantToPassAround);
