For usage.Focus / Blur Events live-window-focus live-window-blur live-focus live-blurFocus and blur events may be bound to DOM elements that emit such events,using the live-blur, and live-focus bindings, for example:">input name="email" live-focus="myfocus" live-blur="myblur"/>Key Events live-window-keyup live-window-keydown live-keyup live-keydown live-keyThe onkeydown, and onkeyup events are supported via the live-keydown, and live-keyupbindings. Each binding supports a live-key attribute, which triggers the event for thespecific key press. If no live-key is provided, the event is triggered for any key press.When pushed, the value sent to the server will contain the "key" that was pressed.See the buttons example for usage.Form Events live-auto-recover live-trigger-action live-disable-with live-feedback-for live-submit live-changeTo handle form changes and submissions, use the live-change and live-submit events. In general,it is preferred to handle input changes at the form level, where all form fields are passed to thehandler's event handler given any single input change. For example, to handle real-time form validationand saving, your template would use both live-change and live-submit bindings.See the form example for usage.Rate Limiting live-debounce live-throttleAll events can be rate-limited on the client by using the live-debounce and live-throttle bindings,with the following behavior:live-debounce accepts either an integer timeout value (in milliseconds),or "blur". When an integer is provided, emitting the event is delayed by the specified milliseconds. When"blur" is provided, emitting the event is delayed until the field is blurred by the user. Debouncing is typicallyused for input elements.live-throttle accepts an integer timeout value to throttle the event in milliseconds. Unlike debounce,throttle will immediately emit the event, then rate limit it at once per provided timeout. Throttling istypically used to rate limit clicks, mouse and keyboard actions.Dom Patching live-updateA container can be marked with live-update, allowing the DOM patch operationsto avoid updating or removing portions of the view, or to append or prepend theupdates rather than replacing the existing contents. This is useful for client-sideinterop with existing libraries that do their own DOM operations. The followinglive-update values are supported:replace - replaces the element with the contentsignore - ignores updates to the DOM regardless of new content changesappend - append the new DOM contents instead of replacingprepend - prepend the new DOM contents instead of replacingWhen using live-update If using "append" or "prepend", a DOM ID must be setfor each child.See the chat example for usage.JS Interop live-hookHooksHooks take the following form. They allow additional javascript to hook into the live lifecycle.These should be used to implement custom behavior and bind additional events which are not supportedout of the box. void; /** * The element is about to be updated in the DOM. * Note: any call here must be synchronous as the operation * cannot be deferred or cancelled. */ beforeUpdate?: () => void; /** * The element has been updated in the DOM by the server */ updated?: () => void; /** * The element is about to be removed from the DOM. * Note: any call here must be synchronous as the operation * cannot be deferred or cancelled. */ beforeDestroy?: () => void; /** * The element has been. blur event and javascript/html. 12.

JavaScript Blur Event (onblur) JavaScript Blur event is opposite of Focus event, it triggers when an element looses its focus. So, blur is a situation when an element gets unfocused after getting focused. The onblur event handler is used to Bind an event handler to The JavaScript blur event or trigger that event on the specified element, optionally passing a map of data. The blur event is sent to an element when the element loses focus. We use this methods .blur( ) signature in our example below which triggers The JavaScript blur event on the specified element. 🎓 DOM Events and JavaScript Course Explore the world of JavaScript Focus and Blur Events, uncove Index of contents Controls Push button Push button description The Push button control mainly expect a click or tap from the user, so we can do whatever thing, like show a specific app view, upload some user input to the app server, etc. A Push button can appear enabled or disabled, can look in various "kind" or styles and finally provide several events ready to be used. Push button CSS rules This control has a default style, and, some control JavaScript properties (see below), can also changes the control style, not to mention the Classes property, that you can use to establish one or more CSS classes to be applied to the control. In addition to that style, you can also set custom CSS rules for the control by using the IDE controls style inspector. If this is not enough, you can include any number of CSS stylesheets in the app by using the app files manager. If you want to use CSS stylesheets, you need to know how to refer to the control, so take a look at the Runtime selectors help topic.
