Twissijiet
Ipprovdi messaġġi ta' feedback kuntestwali għal azzjonijiet tipiċi tal-utent b'numru żgħir ta' messaġġi ta' twissija disponibbli u flessibbli.
Eżempji
It-twissijiet huma disponibbli għal kwalunkwe tul tat-test, kif ukoll buttuna tal-għeluq fakultattiva. Għal stil xieraq, uża waħda mit-tmien klassijiet kuntestwali meħtieġa.alert-success
(eż, ). Għat-tkeċċija inline, uża l- plugin JavaScript ta' allerti .

Twassal tifsira għal teknoloġiji ta' assistenza
L-użu tal-kulur biex iżżid it-tifsira jipprovdi biss indikazzjoni viżwali, li mhux se tiġi mgħoddija lill-utenti ta 'teknoloġiji ta' assistenza - bħal screen readers. Kun żgur li l-informazzjoni indikata bil-kulur hija jew ovvja mill-kontenut innifsu (eż. it-test viżibbli), jew tkun inkluża permezz ta' mezzi alternattivi, bħal test addizzjonali moħbi mal- .visually-hidden
klassi.
Kulur tal-link
Uża l .alert-link
-klassi ta 'utilità biex tipprovdi malajr links ikkuluriti li jaqblu fi kwalunkwe twissija.

Proset!
Aww iva, qrajt b'suċċess dan il-messaġġ ta' twissija importanti. Dan it-test eżempju se jdum ftit itwal sabiex tkun tista' tara kif l-ispazjar fi ħdan twissija jaħdem ma' dan it-tip ta' kontenut.
Kull meta jkollok bżonn, kun żgur li tuża l-utilitajiet tal-marġni biex iżżomm l-affarijiet sbieħ u puliti.
<div class="alert alert-success" role="alert">
<h4 class="alert-heading">Well done!</h4>
<p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
<hr>
<p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>
Ikoni
Bl-istess mod, tista 'tuża utilitajiet tal-flexbox u Ikoni Bootstrap biex toħloq twissijiet b'ikoni. Skont l-ikoni u l-kontenut tiegħek, tista 'tixtieq iżżid aktar utilitajiet jew stili tad-dwana.

Tkeċċija
Bl-użu tal-plugin JavaScript ta' twissija, huwa possibbli li titwarrab kwalunkwe twissija inline. Ara kif:
- Kun żgur li għabbejt il-plugin tat-twissija, jew il-Bootstrap JavaScript miġbur.
- Żid buttuna mill-qrib u l-
.alert-dismissible
klassi, li żżid padding żejjed fuq il-lemin tat-twissija u tpoġġi l-buttuna tal-għeluq. - Fuq il-buttuna tal-għeluq, żid l-
data-bs-dismiss="alert"
attribut, li jqajjem il-funzjonalità JavaScript. Kun żgur li tuża l-<button>
element miegħu għal imġieba xierqa fl-apparati kollha. - Biex tanima twissijiet meta twarrabhom, kun żgur li żżid il- klassijiet
.fade
u ..show
Tista' tara dan fl-azzjoni b'demo live:
<div class="alert alert-warning alert-dismissible fade show" role="alert">
<strong>Holy guacamole!</strong> You should check in on some of those fields below.
<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
</div>
closed.bs.alert
avveniment u b'mod programmatiku jistabbilixxi
focus()
l-aktar post xieraq fil-paġna. Jekk qed tippjana li tmexxi l-fokus għal element mhux interattiv li normalment ma jirċievix fokus, kun żgur li żżid
tabindex="-1"
mal-element.

Imġieba JavaScript
Triggers
Ippermetti t-tkeċċija ta' twissija permezz ta' JavaScript:
var alertList = document.querySelectorAll('.alert')
alertList.forEach(function (alert) {
new bootstrap.Alert(alert)
})
Jew data
b'attributi fuq buttuna fi ħdan it-twissija , kif muri hawn fuq:
<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
Innota li meta tagħlaq twissija tneħħiha mid-DOM.
Metodi
Tista' toħloq istanza ta' twissija mal-kostruttur ta' twissija, pereżempju:
var myAlert = document.getElementById('myAlert')
var bsAlert = new bootstrap.Alert(myAlert)
Dan jagħmel twissija tisma 'għal avvenimenti ikklikkja fuq elementi dixxendenti li għandhom l- data-bs-dismiss="alert"
attribut. (Mhux meħtieġ meta tuża l-awto-inizjalizzazzjoni tad-data-api.)
Metodu | Deskrizzjoni |
---|---|
close |
Jagħlaq twissija billi tneħħiha mid-DOM. Jekk il- klassijiet .fade u .show huma preżenti fuq l-element, it-twissija tisparixxi qabel ma titneħħa. |
dispose |
Jeqred twissija ta' element. (Tneħħi d-dejta maħżuna fuq l-element DOM) |
getInstance |
Metodu statiku li jippermettilek li tikseb l-istanza ta 'twissija assoċjata ma' element DOM, tista 'tużah bħal dan:bootstrap.Alert.getInstance(alert) |
getOrCreateInstance |
Metodu statiku li jirritorna istanza ta' twissija assoċjata ma' element DOM jew toħloq waħda ġdida f'każ li ma kinitx inizjalizzata. Tista' tużah bħal dan:bootstrap.Alert.getOrCreateInstance(element) |
var alertNode = document.querySelector('.alert')
var alert = bootstrap.Alert.getInstance(alertNode)
alert.close()
Avvenimenti
Il-plugin ta' twissija ta' Bootstrap jesponi ftit avvenimenti biex wieħed iqabbad mal-funzjonalità ta' twissija.
Avveniment | Deskrizzjoni |
---|---|
close.bs.alert |
Nirien immedjatament meta close jissejjaħ il-metodu tal-istanza. |
closed.bs.alert |
Tispara meta t-twissija tkun ingħalqet u t-tranżizzjonijiet CSS ikunu tlestew. |
var myAlert = document.getElementById('myAlert')
myAlert.addEventListener('closed.bs.alert', function () {
// do something, for instance, explicitly move focus to the most appropriate element,
// so it doesn't get lost/reset to the start of the page
// document.getElementById('...').focus()
})
