Exactly when does an IFRAME onload event fire?

阅读更多关于 Exactly when does an IFRAME onload event fire?

问题 Does the IFRAME's onload event fire when the HTML has fully downloaded, or only when all dependent elements load as well? (css/js/img) 回答1: The latter: <body onload= fires only when all dependent elements (css/js/img) have been loaded as well. If you want to run JavaScript code when the HTML has been loaded, do this at the end of your HTML: <script>alert('HTML loaded.')</script></body></html> Here is a relevant e-mail thread about the difference between load and ready (jQuery supports both).

阅读更多关于 how to call a window's Loaded event in WPF MVVM?

问题 It is easy enough to create a command from my OnLoaded() event handler code, but how do I call it from the View? <window Loaded="onLoaded"> doesn't cut the cake anymore since it calls code in the xaml.cs.

阅读更多关于 jQuery function triggered on window resize but not on page load

问题 I found this jQuery code that allows to center a div that doesn't have fixed dimensions both horizontally and vertically. It works with the window height and width. So when I resize the window, the div is still centered within the window. My issue is that, right now, it doesn't work unless I resize the window first. So if I just load the page, the div isn't centered unless I manually resize the window. This, of course, is not ideal. So I'm trying to find a way around it. But my jQuery skills
