internetexplorer.application hangs on readystate=1 in VBA

由 拟墨画扇 提交于 2020-07-10 11:22:33
问题 I have an Excel VBA application which uses internetexplorer.application to explore an application. Starting around 2/21/15, this application started failing on readyState being stuck on 1 forever rather than ultimately migrating to 4. This only occurred when navigating the second (or further) link. The first URL works fine. The machine with the problem is a Core i5 M520 CPU (4 CPU) running 64-bit Windows 7. Another machine with a Core 2 Duo T9400 running 32-bit Windows 7 executes the code

Why does MutationObserver fire twice for childList but never for characterData?

由 喜夏-厌秋 提交于 2020-07-06 10:43:21
问题 I have a simple MutationObserver setup as a test. The HTML has a span whose text content gets updated once per second (and a div for messages): <span class="tester"></span> <div id="msg"></div> The MutationObserver is set to watch .tester and writes text to the #msg div when it observes a change. Meanwhile, a setInterval() runs once/second to change the text in .tester : var target = document.querySelector('.tester'); var observer = new MutationObserver(function(mutations) { mutations.forEach

DOMContentLoaded not firing after navigation but fires on page reload when using javascript_pack_tag

由 放肆的年华 提交于 2020-06-28 04:28:09
问题 I'm working with a Rails 6 rc1 project with React and Webpacker. I'm currently using javascript_pack_tag to render React components in my Rails app. I'm trying not to use a gem like react-rails just to keep things simple. Today I found a weird behavior where my React component would not render after the page is navigated to from a link. However, on a page reload, my component is rendered. Gemfile : gem 'rails', '~> 6.0.0.rc1' gem 'pg', '>= 0.18', '< 2.0' gem 'puma', '~> 3.11' gem 'sass-rails'

JavaScript append and prepend vs jQuery append and prepend

由 坚强是说给别人听的谎言 提交于 2020-06-27 11:09:23
问题 QA Style I recently read an article and it says that JavaScript has implemented append and prepend methods inspired from jQuery. It was a new knowledge for me because as far as I know to append an element, I had to use element.appendChild and to prepend an element, I had to use element.insertBefore(newElement,element.children[0]) .
