Tahadhari
Toa ujumbe wa maoni ya muktadha kwa vitendo vya kawaida vya mtumiaji na ujumbe mfupi wa arifa unaopatikana na rahisi.
Arifa zinapatikana kwa urefu wowote wa maandishi, pamoja na kitufe cha hiari cha kukataa. Kwa mtindo unaofaa, tumia mojawapo ya madarasa manane ya muktadha yanayohitajika.alert-success
(kwa mfano, ). Kwa uondoaji wa ndani, tumia arifa programu jalizi ya jQuery .
<div class="alert alert-primary" role="alert">
This is a primary alert—check it out!
</div>
<div class="alert alert-secondary" role="alert">
This is a secondary alert—check it out!
</div>
<div class="alert alert-success" role="alert">
This is a success alert—check it out!
</div>
<div class="alert alert-danger" role="alert">
This is a danger alert—check it out!
</div>
<div class="alert alert-warning" role="alert">
This is a warning alert—check it out!
</div>
<div class="alert alert-info" role="alert">
This is a info alert—check it out!
</div>
<div class="alert alert-light" role="alert">
This is a light alert—check it out!
</div>
<div class="alert alert-dark" role="alert">
This is a dark alert—check it out!
</div>
Kuwasilisha maana kwa teknolojia za usaidizi
Kutumia rangi ili kuongeza maana hutoa tu kielelezo cha kuona, ambacho hakitawasilishwa kwa watumiaji wa teknolojia saidizi - kama vile visoma skrini. Hakikisha kwamba maelezo yanayoashiriwa na rangi ni dhahiri kutoka kwa maudhui yenyewe (km maandishi yanayoonekana), au yanajumuishwa kupitia njia mbadala, kama vile maandishi ya ziada yaliyofichwa na .sr-only
darasa.
Tumia .alert-link
darasa la matumizi ili kutoa kwa haraka viungo vya rangi zinazolingana ndani ya tahadhari yoyote.
<div class="alert alert-primary" role="alert">
This is a primary alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-secondary" role="alert">
This is a secondary alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-success" role="alert">
This is a success alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-danger" role="alert">
This is a danger alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-warning" role="alert">
This is a warning alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-info" role="alert">
This is a info alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
<div class="alert alert-light" role="alert">

</div>
<div class="alert alert-dark" role="alert">
This is a dark alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>
Arifa zinaweza pia kuwa na vipengele vya ziada vya HTML kama vile vichwa, aya na vigawanyiko.
Umefanya vizuri!
Aww yeah, umefaulu kusoma ujumbe huu muhimu wa tahadhari. Maandishi ya mfano huu yatakwenda kwa muda mrefu zaidi ili uweze kuona jinsi nafasi kati ya arifa inavyofanya kazi na aina hii ya maudhui.
Wakati wowote unapohitaji, hakikisha unatumia huduma za ukingo ili kuweka mambo vizuri na nadhifu.
<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>
Kwa kutumia programu-jalizi ya JavaScript ya tahadhari, inawezekana kuondoa arifa yoyote iliyo ndani ya mstari. Hivi ndivyo jinsi:
- Hakikisha kuwa umepakia programu-jalizi ya tahadhari, au JavaScript iliyokusanywa ya Bootstrap.
- Ikiwa unaunda JavaScript yetu kutoka kwa chanzo, inahitaji
util.js
. Toleo lililokusanywa linajumuisha hii. - Ongeza kitufe cha kukataa na
.alert-dismissible
darasa, ambalo huongeza pedi za ziada upande wa kulia wa arifa na kuweka.close
kitufe. - Kwenye kitufe cha kuondoa, ongeza
data-dismiss="alert"
sifa, ambayo huanzisha utendaji wa JavaScript. Hakikisha unatumia<button>
kipengele nacho kwa tabia ifaayo kwenye vifaa vyote. - Ili kuhuisha arifa unapoziondoa, hakikisha kuwa umeongeza
.fade
na.show
madarasa.
Unaweza kuona hili likitekelezwa na onyesho la moja kwa moja:
<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="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
Washa uondoaji wa arifa kupitia JavaScript:
Au na data
sifa kwenye kitufe ndani ya arifa , kama inavyoonyeshwa hapo juu:
Kumbuka kuwa kufunga tahadhari kutaiondoa kutoka kwa DOM.
Njia | Maelezo |
---|---|
$().alert() |
Hufanya arifa ya kusikiliza kwa matukio ya kubofya kwenye vipengele vya kizazi ambavyo vina data-dismiss="alert" sifa. (Sio lazima unapotumia uanzishaji kiotomatiki wa data-api.) |
$().alert('close') |
Hufunga arifa kwa kuiondoa kwenye DOM. Ikiwa .fade na .show darasa zipo kwenye kipengele, tahadhari itafifia kabla ya kuondolewa. |
$().alert('dispose') |
Huharibu arifa ya kipengele. |
Programu-jalizi ya tahadhari ya Bootstrap inafichua matukio machache ya kuunganisha katika utendaji wa tahadhari.
Tukio | Maelezo |
---|---|
close.bs.alert |
Tukio hili huwaka mara moja wakati close njia ya mfano inaitwa. |
closed.bs.alert |
Tukio hili linafutwa wakati tahadhari imefungwa (itasubiri mabadiliko ya CSS kukamilika). |
