Why does jQuery or a DOM method such as getElementById not find the element?

What are the possible reasons for document.getElementById , $("#id") or any other DOM method / jQuery selector not finding the elements?

为什么jQuery或像getElementById这样的DOM方法找不到元素?

document.getElementById , $("#id")或任何其他DOM方法/ jQuery选择器未找到元素的可能原因是什么? 示例问题包括: jQuery默默无法绑定事件处理程序,并且返回null的标准DOM方法导致错误: Uncaught TypeError:无法设置null的属性'...' 当您的脚本运行时,您尝试查找的元素不在DOM中。 您的DOM依赖脚本的位置可能会对其行为产生深远影响。 浏览器从上到下解析HTML文档。 元素被添加到DOM并且脚

Sequencing ajax requests

I find I sometimes need to iterate some collection and make an ajax call for each element. I want each call to return before moving to the next element so that I don't blast the server with requests - which often leads to other issues. And I don't want to set async to false and freeze the browser. Usually this involves setting up some kind of iterator context that i step thru upon eac

排序ajax请求

我发现我有时需要迭代一些集合,并为每个元素进行ajax调用。 我希望每个调用都能在返回到下一个元素之前返回,这样我就不会用请求爆炸服务器 - 这往往会导致其他问题。 我不想将异步设置为false并冻结浏览器。 通常这包括设置某种迭代器上下文,我会在每次成功回调时执行一次。 我认为必须有一种更简洁的方式? 有没有人有一个聪明的设计模式,如何整齐地通过一个集合为每个项目制作Ajax调用? jQuery 1.5+ 我开发了

browser onload event when clicking the back button?

For all major browsers (except IE), the JavaScript onload event doesn't fire when the page loads as a result of a back button operation — it only fires when the page is first loaded. Can someone point me at some sample cross-browser code (Firefox, Opera, Safari, IE, …) that solves this problem? I'm familiar with Firefox's pageshow event but unfortunately neither Opera nor Safari im

浏览器onload事件点击后退按钮时?

对于所有主流浏览器(IE除外),当页面加载时,JavaScript onload事件不会触发后退按钮操作 - 它只会在页面首次加载时触发。 有人能指出我解决这个问题的一些示例跨浏览器代码(Firefox,Opera,Safari,IE,...)吗? 我熟悉Firefox的pageshow事件,但不幸的是,Opera和Safari都没有实现这个功能。 伙计们,我发现JQuery只有一个效果:当按下后退按钮时,页面被重新加载。 这与“ 准备好 ”无关。 这个怎么用? 那么,JQ
