Where should I put <script> tags in HTML markup?

When embedding JavaScript in an HTML document, where is the proper place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). Th

我应该在HTML标记中放置<script>标记?

将JavaScript嵌入到HTML文档中时,放置<script>标记和包含JavaScript的适当位置在哪里? 我似乎还记得,你不应该把它们放在<head>部分,但是放在<body>部分的开头也是不好的,因为在页面完全呈现之前必须解析JavaScript(或类似的东西)。 这似乎将<body>部分的末尾作为<script>标记的逻辑位置。 那么,放置<script>标签的正确位置在哪里? (这个问题引用了这个问题,其中有人建议Ja

How can you check for a #hash in a URL using JavaScript?

JavaScript: Learning how to "consume RESTful APIs"

I've been coding JS for a few years, and am now learning more. Seeing a lot of employers asking for "knowledge of REST APIs" or "experience consuming RESTful services." I know the basics of AJAX, both in native JS and jQuery. I've done a fair bit 'o goggling on REST, both on SO and the web. There seems to be a ton of info on how to build RESTful APIs server-si

JavaScript:学习如何“使用RESTful API”

我一直在编写JS几年,现在正在学习更多。 看到很多雇主要求“了解REST API”或“体验消费RESTful服务”。 我知道AJAX的基础知识,包括原生JS和jQuery。 我在SO和网络上做了一些相当不错的REST操作。 似乎有大量关于如何使用JAVA,C#等构建RESTful API服务器端的信息,但关于如何使用JavaScript访问这些服务的信息很少。 以下是问题: “使用RESTful服务”是另一种说“使用AJAX从服务器获取数据”的方式,还是其他的方式? 如

Rails 4: how to use $(document).ready() with turbo

I ran into an issue in my Rails 4 app while trying to organize JS files "the rails way". They were previously scattered across different views. I organized them into separate files and compile them with the assets pipeline. However, I just learned that jQuery's "ready" event doesn't fire on subsequent clicks when turbo-linking is turned on. The first time you load

Rails 4:如何使用$(document).ready()和turbo

我在试图组织JS文件“rails方式”时遇到了Rails 4应用程序中的一个问题。 他们以前分散在不同的意见。 我将它们组织成单独的文件并使用资产管道进行编译。 不过,我刚刚了解到,在启用turbo链接时,jQuery的“ready”事件不会触发随后的点击。 你第一次加载一个页面它的工作。 但是当你点击一个链接时, ready( function($) {任何内容都不会被执行(因为页面实际上并没有再次加载)好解释:这里。 所以我的问题是:什么是正确

window.onload vs $(document).ready()

JavaScript的window.onload和jQuery的$(document).ready()方法有什么区别? The ready event occurs after the HTML document has been loaded, while the onload event occurs later, when all content (eg images) also has been loaded. The onload event is a standard event in the DOM, while the ready event is specific to jQuery. The purpose of the ready event is that it should occur as early as possible af

window.onload vs $(document).ready()

JavaScript的window.onload和jQuery的$(document).ready()方法有什么区别? ready事件发生在HTML文档被加载后,而onload事件发生在稍后,当所有内容(例如图像)也被加载时。 onload事件是DOM中的标准事件,而ready事件特定于jQuery。 ready事件的目的是在文档加载后应尽早发生,以便为页面中的元素添加功能的代码不必等待所有内容加载。 window.onload是内置的JavaScript事件,但由于它的实现在浏览器(Firefox,Internet

jQuery document.createElement equivalent?

I'm refactoring some old JavaScript code and there's a lot of DOM manipulation going on. var d = document; var odv = d.createElement("div"); odv.style.display = "none"; this.OuterDiv = odv; var t = d.createElement("table"); t.cellSpacing = 0; t.className = "text"; odv.appendChild(t); I would like to know if there is a better way to do this using jQuery. I've been experimenting wit

jQuery document.createElement是否等同?

我正在重构一些旧的JavaScript代码,并且有很多DOM操作正在进行。 var d = document; var odv = d.createElement("div"); odv.style.display = "none"; this.OuterDiv = odv; var t = d.createElement("table"); t.cellSpacing = 0; t.className = "text"; odv.appendChild(t); 我想知道是否有更好的方法来使用jQuery来做到这一点。 我一直在试验: var odv = $.create("div"); $.append(odv); // And many more 但我不确

Is checking for the readiness of the DOM overkill?

I'm developing a platform for developing desktop apps with web technologies. In the course of doing so I've been trying to get some document/on-ready functionality working with the browser I will be integrating into the platform. That's why I'd previously asked this this question here on SO: javascript-framework-that-primarily-provides-just-document-onready-functionality Howev

是否正在检查DOM过度使用的准备情况?

我正在开发一个使用Web技术开发桌面应用程序的平台。 在这样做的过程中,我一直在努力获得一些与浏览器配合使用的文档/准备就绪功能,我将集成到该平台中。 这就是为什么我以前在SO上问过这个问题:javascript-framework-that-mainly-provides-just-document-onready-functionality 然而,我无法获得我选择的浏览器(嘘,它的秘密;)成功地利用上述唯一的答案建议的功能。 所以,在试图弄清楚可能会发生什么的过程中,我偶

how to call a function when the page/DOM is ready for it

This question already has an answer here: $(document).ready equivalent without jQuery 31 answers The simplest thing to do in the absence of a framework that does all the cross-browser compatibility for you is to just put a call to your code at the end of the body. This is faster to execute than an onload handler because this waits only for the DOM to be ready, not for all images to load. An

如何在页面/ DOM准备好时调用函数

这个问题在这里已经有了答案: $(document).ready没有jQuery 31个答案 在没有为您提供所有跨浏览器兼容性的框架的情况下,最简单的方法就是在本体的最后调用代码。 这比onload处理程序执行速度更快,因为它仅等待DOM准备就绪,而不是等待所有图像加载。 而且,这适用于每个浏览器。 <html> <head> </head> <body> Your HTML here <script> // self executing function here (function()
