document.ready()is a jQuery event. JQuery's document.ready()method gets called as soon as the DOM is ready (which means that the browser has parsed the HTML and built the DOM tree). This allows you to run code as soon as the document is ready to be manipulated.
document.ready()是一个 jQuery 事件。document.ready()一旦 DOM 准备好（这意味着浏览器已经解析了 HTML 并构建了 DOM 树），JQuery 的方法就会被调用。这使您可以在文档准备好进行操作时立即运行代码。
For example, if a browser supports the DOMContentLoaded event (as many non-IE browsers do), then it will fire on that event. However, IE can't safely fire until the document's readyState reaches “complete”, which is typically later.
例如，如果浏览器支持 DOMContentLoaded 事件（就像许多非 IE 浏览器一样），那么它将在该事件上触发。然而，IE 不能安全地触发，直到文档的 readyState 达到“完成”，这通常是更晚的。
You can find more info here(of course, this requires jQuery to be loaded)
您可以在此处找到更多信息（当然，这需要加载 jQuery）
