loading

I want to load a different image(fake avatar) while the final avatar image is loading. The idea is to detect when the prop image is loaded and change a state. Is it possible? Some ideas? Thank you! class ImageUser extends React.Component { constructor(props) { super(props); this.state = {userImageLoaded: false}; let imageSrc = ""; if (!this.props.userImage) { imageSrc = this.props.noUserImage; } else { imageSrc = this.props.userImage; } this.loadingImage = <img className={styles.imageUser} src={this.props.loadingImage} alt="2"/>; this.userImage = <img onLoad={this.setState({userImageLoaded:

Is there a common term / catch-phrase for the opposite of lazy loading? The oposite term for lazy loading is eager loading. Eager loading is essentially computing the tasks when you ask for it. Lazy Loading is when you only do the computation when it is required. I've seen the terms "Eager Loading" and "Aggressive Initialization" both used. I'd say that the opposite of lazy is proactive loading , i.e. loading something in advance, before it's really needed. However it's hard to pick the opposites when you have 3 entities {lazy, eager, proactive} 来源： https://stackoverflow.com/questions/5427949

This is a Q&A post. To inform the many other users I saw who struggled with this issue as I browsed through StackOverflow's database. None of these users ever got a solid answer (and most of them were posing the question years ago so I wasn't going to bump the post). The issue many struggled with is as follows: When you try to load a page in a UIWebView and the page then loads another page maybe via an iFrame or it loads an advertisement through javascript you end up getting the page loading function called again and if you are using a UIActivityIndicator it will get called again as well and

There are some others applications doing this, like Twitter, Facebook, or even native applications such as Android Market. When you want to display a list of items retrieved from the internet, this looks like a standard way for displaying the user some notification about action in progress. This is a white background screen with an animated spinning wheel and a "Loading..." text. Does somebody know how to do this? I've been able to do something similar with this code, but I don't like it too much yet. Still work in progress: <ListView android:id="@+id/post_list" android:layout_width="fill

How can I add a custom javascript file (let's say custom.js ) to a mediawiki installation? For instance, if I put custom.js under the folder resources/lib/ , how do I get that to be loaded on every page? I am not trying to do this as part of an extension, and I would prefer to keep my changes in LocalSettings.php . As garryp has already suggested, you can put the JavaScript code into MediaWiki:Common.js . Note that this is not a file, but simply a page you can edit (as an administrator) on your wiki. For example, here's the MediaWiki:Common.js page on the English Wikipedia . JavaScript code

I'm looking for an animated Loading icon that is also transparent; however (I know I'm lazy) I dont want to make my own. Please forgive me if this is not the correct forum for this post, I've just had so much luck here in the past. does anyone know where I can find one of these....it needs to be very small (icon size). http://www.ajaxload.info/ is your friend. However, there are no "animated pngs" simply because no
