DOMAttrModified visual attributes

问题 I have DOMAttrModified working on webkit with some patches and I was wondering changing of what kind of attributes will trigger this event? For example, it does not trigger when I change innerHTML. And is there an easy way for me to know which of these attributes directly change user interface. For example id does not directly, but indirectly javascript could change it depending on the value of id. Thanks! 回答1: I believe the event is dispatched whenever a DOM attribute is modified. innerHTML

问题 I have a question about DOMAttrModified. Which changes to an HTML Element properties triggers the DOMAttrModified event (specifically interested in Firefox, but an answer that applies to other browsers might suffice too)? I have the following test case : var elem = document.createElement('input'); document.body.appendChild(elem); elem.id = 'inputId'; // triggers DOMAttrModified elem.type = 'text'; // triggers DOMAttrModified elem.value = 'inputValue'; // DOES NOT trigger DOMAttrModified elem

DOMNodeInserted or hashchange

问题 I am trying to write a JavaScript script that is "overlayed" on top of a Facebook page. It uses DOMContentLoaded to detect when content is loaded, then adds some extra stuff in. However, because Facebook doesn't actually "reload" the page when going to a new page (it just uses AJAX), the DOMContentLoaded handler doesn't run again, even though there is new stuff to look through. Anyway, to detect the change, I thought about using onhashchange since Facebook used to change the page's hash, but

What is the most efficient way of detecting when an element with a particular ID is inserted in the DOM

由 本小妞迷上赌 提交于 2019-12-08 05:24:50
问题 As the title suggests, I want to detect the exact timestamp when an element with a particular id or CSS class is inserted into the DOM (and possibly detect when it is removed). The most obvious method is to poll the document periodically, by calling document.getElementById with the id of the element I want to find, but this method is not very accurate and can be very performance intensive if I have multiple elements I want to detect. I took a look at Mutation Events and Mutation Observers,

问题 I need to trigger an action when content is added to a Web page. The updates can be of different nature (AJAX, delayed scripts, user action for example) and are not under my control. I wanted to use DOM mutation events, but they are not available in all browsers. Are there cross-browser libraries for this, that offer a fallback plan? Also, I'd be interested to know if Internet Explorer 9 will support these DOM mutation events. Thanks! 回答1: There are two ways to do this... One, you can take a
