Changelog

[1.6.1] - 2021-11-22

• A new HX-Retarget header allows you to change the default target of returned content
• The htmx:beforeSwap event now includes another configurable property: detail.isError which can be used to indicate if a given response should be treated as an error or not
• The htmx:afterRequest event has two new detail properties: success and failed, allowing you to write trigger filters in htmx or hyperscript:

    on htmx:afterRequest[failed]
      set #myCheckbox's checked to true

• Fixed the from: option in hx-trigger to support closest <CSS selector> and find <CSS selector> forms
• Don't boost anchor tags with an explicit target set
• Don't cancel all events on boosted elements, only the events that naturally trigger them (click for anchors, submit for forms)
• Persist revealed state in the DOM so that on history navigation, revealed elements are not re-requested
• Process all hx-ext attributes, even if no other htmx attribute is on the element
• Snapshot the current URL on load so that history support works properly after a page refresh occurs
• Many, many documentation updates (thank you to all the contributors!)

[1.6.0] - 2021-10-01

• Completely reworked <script> tag support that now supports the <script src="...'/> form
• You can now use the value unset to clear a property that would normally be inherited (e.g. hx-confirm)
• The htmx-added class is added to new content before a swap and removed after the settle phase, which allows you more flexibility in writing CSS transitions for added content (rather than relying on the target, as with htmx-settling)
• The htmx:beforeSwap event has been updated to allow you to configure swapping behavior
• Improved <title> extraction support
• You can listen to events on the window object using the from: modifier in hx-trigger
• The root option of the intersect event was fixed
• Boosted forms respect the enctype declaration
• The HX-Boosted header will be sent on requests from boosted elements
• Promises are not returned from the main ajax function unless it is an api call (i.e. htmx.ajax)

[1.5.0] - 2021-7-12

• Support tracking of button clicked during a form submission
• Conditional polling via the hx-trigger attribute
• document is now a valid pseudo-selector on the hx-trigger from: argument, allowing you to listen for events on the document.
• Added the hx-request attribute, allowing you to configure the following aspects of the request
  • timeout - the timeout of the request
  • credentials - if the request will send credentials
  • noHeaders - strips all headers from the request
• Along with the above attribute, you can configure the default values for each of these via the corresponding htmx.config properties (e.g. htmx.config.timeout)
• Both the scroll and show options on hx-swap now support extended syntax for selecting the element to scroll or to show, including the pseudo-selectors window:top and window:bottom.

[1.4.1] - 2021-6-1

• typo fix

[1.4.0] - 2021-5-25

• Added the queue option to the hx-trigger attribute, allowing you to specify how events should be queued when they are received with a request in flight
• The htmx.config.useTemplateFragments option was added, allowing you to use HTML template tags for parsing content from the server. This allows you to use Out of Band content when returning things like table rows, but it is not IE11 compatible.
• The defaultSettleDelay was dropped to 20ms from 100ms
• Introduced a new synthetic event, intersect that allows you to trigger when an item is scrolled into view as specified by the IntersectionObserver API
• Fixed timing issue that caused exceptions in the reveal logic when scrolling at incredible speeds - bigskysoftware#463
• Fixed bug causing SVG titles to be incorrectly used as page title - bigskysoftware#459
• Boosted forms that issue a GET will now push the URL by default - bigskysoftware#485
• Better dispatch of request events when an element is removed from the DOM
• Fixed a bug causing hx-prompt to fail
• The htmx.config.withCredentials option was added, to send credentials with ajax requests (default is false)
• The throttle option on hx-trigger does not delay the initial request any longer
• The meta key is ignored on boosted links
• <script> tags are now evaluated in the global scope
• hx-swap now supports the none option
• Safari text selection bug - bigskysoftware#438

[1.3.3] - 2021-4-5

• Added the hx-disabled attribute to allow htmx to be turned off for parts of the DOM
• SSE now uses a full-jitter exponential backoff algorithm on reconnection, using the htmx.config.wsReconnectDelay setting

[1.3.2] - 2021-3-9

• Bug fixes

[1.3.1] - 2021-3-9

• IE11 fixes

[1.3.0] - 2021-3-6

• Support a target modifier on hx-trigger to filter based on the element targeted by an event. This allows lazy binding to that target selector.
• Events are no longer consumed by the first element that might handle them, unless the consume keyword is added to the hx-trigger specification
• Added the htmx:beforeSend event, fired just before an ajax request begins
• SSE swaps are properly settled
• Fixed bug that was improperly cancelling all clicks on anchors
• htmx.ajax() now returns a promise

[1.2.1] - 2021-2-19

• Fixed an issue with the history cache, where the cache was getting blown out after the first navigation backwards
• Added the htmx.config.refreshOnHistoryMiss option, allowing users to trigger a full page refresh on history cache miss rather than issuing an AJAX request

[1.2.0] - 2021-2-13

New Features

• hx-vars has been deprecated in favor of hx-vals
• hx-vals now supports a javascript: prefix to achieve the behavior that hx-vars provided
• The new hx-headers attribute allows you to add headers to a request via an attribute. Like hx-vals it supports JSON or javascript via the javascript: prefix
• hx-include will now include all inputs under an element, even if that element is not a form tag
• The preload extension now offers a preload-images="true" attribute that will aggressively load images in preloaded content
• On requests driven by a history cache miss, the new HX-History-Restore-Request header is included so that the server can differentiate between history requests and normal requests

Improvements & Bug fixes

• Improved handling of precedence of input values to favor the enclosing form (see here)
• Moved event filtering logic after preventDefault so filtering still allows events to be properly handled
• No longer trigger after swap events on elements that have been removed via an outerHTML swap
• Properly remove event handlers added to other elements when an element is removed from the DOM
• Handle the scroll: modifier in hx-swap properly when an outerHTML swap occurs
• Lots of docs fixes

[1.1.0] - 2021-1-6

• Newly added preload extension allows you to preload resources for lower latency requests!
• Support the ignore: modifier for extensions
• Updated form variable order inclusion to include the enclosing form last so that, in the presence of multiple values, the most relevant value is the most likely to be selected by the server
• Support for the htmx.ajax() javascript function, to issue an htmx-style ajax request from javascript
• Removed the following htmx request headers for better cache behavior: HX-Event-Target, HX-Active-Element, HX-Active-Element-Name, HX-Active-Element-Value
• Added the hx-preserve attribute, which allows you to preserve elements across requests (for example, to keep a video element playing properly)
• The path-deps now surfaces a small api for refreshing path dependencies manually in javascript
• Now support the from: clause on hx-trigger to allow an element to respond to events on other elements.
• Added the htmx:beforeProcessNode event, renamed the (previously undocumented) htmx:processedNode to htmx:afterProcessNode
• Added closest syntax support for the hx-indicator attribute
• Added on load support for the newest version of hyperscript
• Added the htmx.config.allowEval configuration value, for CSP compatibility
• Bug fixes & improvements

[1.0.1] - 2020-12-04

• AJAX file upload now correctly fires events, allowing for a proper progress bar
• htmx api functions that expect an element now can accept a string selector instead:

   htmx.on('#form', 'htmx:xhr:progress', function(evt) {
     htmx.find('#progress').setAttribute('value', evt.detail.loaded/evt.detail.total * 100)
   });

• The SSE attribute hx-sse allows for swapping content directly on an event, in addition to triggering an htmx element, with the new swap:<event name> syntax.
• hx-target now supports a find syntax to find elements below the element by a CSS selector
• htmx plays better with deferred loading and many package managers
