I am n00b at rails. The question is very simple, i want to know how can i make a javascript function call inside body tag on the onLoad event. I'm asking this because in the views i can't find any body or head tag (It's like they are generated elsewhere). Thanks You do not need to modify the body tag to associate a Javascript function with onload. Instead of using the onload a
我在轨道n00b。 这个问题很简单,我想知道如何在onLoad事件的body标签内部调用javascript函数。 我在问这是因为在视图中我找不到任何身体或头标签(就像他们在其他地方产生的一样)。 谢谢 您不需要修改body标签以将Javascript函数与onload相关联。 不用在body上使用onload属性,你可以在外部Javascript文件中将函数赋值给window.onload。 还有更高级的方法,使用事件监听器来做同样的事情(在页面加载时触发函数),
The question is so like a zillion others here and on the web - How to check if DOM has loaded in Javascript? But here's the catch: Without using a framework like jQuery etc; Without knowing if your script has been loaded via a statically placed <script> tag or via some other Javascript much later after the DOM has already loaded. Can this be done more or less reliably and with cr
这个问题是如此像在这里和在网络上的其他人 - 如何检查DOM是否加载了Javascript? 但是这里有一个问题: 不使用像jQuery等框架; 不知道您的脚本是否已经通过静态放置的<script>标记加载,或者在DOM已经加载后很久以后通过其他Javascript加载。 这可以或多或少可靠地完成,并且具有跨浏览器兼容性? 补充:让我澄清一下:我正在编写一个可以包含在任意网页中的独立.JS文件。 我想在加载DOM 之后执行代码。 但我
When CSS elements are transformed out of their original location the transform-origin doesn't move with them; making all subsequent transforms and rotations still originate from it's original transform-origin ( example below ). There is one way around this that I know of... and that's to keep adding all new transforms to the right of the previous ones. like this: transform: transl
当CSS元素从原始位置转换出来时, transform-origin不随它们移动; 使所有后续的变换和旋转仍然源自它的原始transform-origin (下面的例子)。 有一种方法可以解决这个问题,那就是不断添加所有新变换到前一个变换的右侧。 像这样: transform: translateY ( -5rem ) rotate( 45deg ) translateY( -10rem ) rotate( 15deg )...等等。这似乎总是根据需要从当前元素的中心开始新的变换。 问题 当您使用这种技术基于用户输
I'm using switch-case statements on regular bases in ECMAscript. Beside my personal endorsement about it, there is tons of specialist literature out, about performance in this language in general and about conditional statements specifically. One good example I remember for instance, is the excellent book "High Performance Javascript" by Nicholas Zakas. Like in many other books
我在ECMAscript中定期使用switch-case语句。 除了我个人对此的认可之外,还有大量的专业文献,关于一般这种语言的表现和关于条件表述的具体内容。 我记得的一个很好的例子就是Nicholas Zakas出色的书“High Performance Javascript”。 就像在其他许多书籍和文章中一样,有人说,当你使用两个以上的条件案例时, switch-case语句总是比if (else)语句快。 在我所知的任何类C语言中, switch-case语句不过是一个二进制哈希映射
Ok, so let me tell you where I'm at. The audio file displays and loads. you can click play to play it. The jQuery isn't autoplaying the material. I'm having to load in the file based on the href of the link. Code is below. Trying to get this to autoplay. $('.voiceLink a', resbox).click(function(e){ e.preventDefault(); var link = $(thi
好的,让我告诉你我在哪里。 音频文件显示并加载。 你可以点击播放来播放它。 jQuery不会自动调整材质。 我不得不根据链接的href加载文件。 代码如下。 试图让这个自动播放。 $('.voiceLink a', resbox).click(function(e){ e.preventDefault(); var link = $(this).prop('href'), audio = $('.audioControl', el.parent()); audio.fin
I am creating a HTML5 music website for mobile users.The goal is to get it running completely in mobile browsers.. The issue is that when a user selects a track to play, they are taken to the "player" page.I then AJAX in a HTML5 audio element in with the autoplay attribute set to true. This works great on desktops, not so much on mobile. The track is not playing though once this pa
我正在为移动用户创建一个HTML5音乐网站。目标是让它完全在移动浏览器中运行。 问题在于,当用户选择要播放的曲目时,它们将被带到“播放器”页面。然后,我将AJAX放入一个HTML5音频元素中,并将autoplay属性设置为true。 这在桌面上非常适用,而不是在移动设备上。 虽然一旦达到该页面,曲目并不播放,而用户需要明确地从该播放器页面点击播放以便开始播放音频。 关于如何调整我的流量以便加载播放页面后自动播放音频的任何
I'm newbie in javascript.I ever read the article with the SAEF,while i still have question, the code is below: var addEvent = (function( window, document ) { if ( document.addEventListener ) { return function ( elem, type, callback ) { //if elem exist and is a single node. if ( elem && !elem.length || elem === window ) { elem.addEv
我是javascript中的新手。我曾经阅读过有关SAEF的文章,但我仍然有疑问,代码如下: var addEvent = (function( window, document ) { if ( document.addEventListener ) { return function ( elem, type, callback ) { //if elem exist and is a single node. if ( elem && !elem.length || elem === window ) { elem.addEventListener( type, callback, false )
I am using jPLayer to play mp3's for a project. They mp3's will be loaded dynamically from a database. I am trying to create the links that will load the selected mp3 into the player. Currently I have which does does not work. I believe I am doing something incorrectly with the click event telling what mp3 to play. If I hardcode the path it works fine but I do not want to set it up t
我正在使用jPLayer为一个项目播放mp3。 他们的mp3将从数据库动态加载。 我正在尝试创建将选定的mp3加载到播放器的链接。 目前我有哪些不起作用。 我相信我做了一些错误的事情,点击事件告诉你要播放哪些mp3。 如果我硬编码的路径工作正常,但我不想这样设置,因为可能有数百个媒体文件。 $(document).ready(function(){ $("#jquery_jplayer_1").jPlayer({ ready: function () { $(this).jPlayer
