Matohi
Whakaratohia nga karere urupare horopaki mo nga mahi a nga kaiwhakamahi me te ringaringa o nga karere matohi e waatea ana me te ngawari.
Tauira
E waatea ana nga matohi mo te roanga o te kuputuhi, me te paatene kati. Kia tika te hanga, whakamahia tetahi o nga karaehe horopaki e waru ( hei tauira, .alert-success
). Mo te whakakore i te raarangi, whakamahia te mono JavaScript matohi .
<div class="alert alert-primary" role="alert">
A simple primary alert—check it out!
</div>
<div class="alert alert-secondary" role="alert">
A simple secondary alert—check it out!
</div>
<div class="alert alert-success" role="alert">
A simple success alert—check it out!
</div>
<div class="alert alert-danger" role="alert">
A simple danger alert—check it out!
</div>
<div class="alert alert-warning" role="alert">
A simple warning alert—check it out!
</div>
<div class="alert alert-info" role="alert">

</div>
<div class="alert alert-light" role="alert">
A simple light alert—check it out!
</div>
<div class="alert alert-dark" role="alert">

</div>
Te kawe i te tikanga ki nga hangarau awhina
Ko te whakamahi i te tae ki te taapiri i te tikanga he tohu tirohanga noa iho, kaore e tukuna ki nga kaiwhakamahi hangarau awhina - penei i nga kaipanui mata. Me mohio kei te kitea nga korero e tohuhia ana e te tae mai i te ihirangi ake (hei tauira, te tuhinga ka kitea), ka whakaurua ranei ma etahi atu huarahi, penei i etahi atu tuhinga huna ki te .visually-hidden
akomanga.
He tauira ora
Patohia te paatene i raro nei hei whakaatu i tetahi matohi (kua huna me nga momo raarangi hei tiimata), ka peia (ka whakangaro) me te paatene kati kua whakauruhia.
<div id="liveAlertPlaceholder"></div>
<button type="button" class="btn btn-primary" id="liveAlertBtn">Show live alert</button>
Ka whakamahia e matou te JavaScript e whai ake nei hei whakaoho i ta maatau whakaaturanga mataaratanga ora:
var alertPlaceholder = document.getElementById('liveAlertPlaceholder')
var alertTrigger = document.getElementById('liveAlertBtn')
function alert(message, type) {
var wrapper = document.createElement('div')
wrapper.innerHTML = '<div class="alert alert-' + type + ' alert-dismissible" role="alert">' + message + '<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button></div>'
alertPlaceholder.append(wrapper)
}
if (alertTrigger) {
alertTrigger.addEventListener('click', function () {
alert('Nice, you triggered this alert message!', 'success')
})
}
Tae hono
Whakamahia te .alert-link
karaehe whaipainga ki te whakarato tere i nga hononga tae orite ki roto i tetahi matohi.
<div class="alert alert-primary" role="alert">
A simple 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">

</div>
He ihirangi taapiri
Ka taea hoki e nga matohi etahi atu huānga HTML penei i nga pane, nga kowae me nga wehewehenga.
Ka pai!
Ae, i pai to panui i tenei karere matohi nui. He roa ake te haere o tenei tauira kuputuhi kia kite ai koe me pehea te mahi a te mokowā i roto i te matohi me tenei momo ihirangi.
I nga wa katoa e hiahia ana koe, kia mohio koe ki te whakamahi i nga taputapu tawhē hei pupuri i nga mea pai me te pai.
<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>
Tohu
Waihoki, ka taea e koe te whakamahi i nga taputapu flexbox me nga Tohu Bootstrap hei hanga matohi me nga tohu. I runga i o tohu me o ihirangi, ka hiahia pea koe ki te taapiri atu i nga taputapu me nga momo ritenga.

Me neke atu i te kotahi ata mo o matohi? Whakaarohia te whakamahi i etahi atu tohu Bootstrap me te hanga i tetahi sprite SVG o te rohe penei kia ngawari te tohutoro i nga tohu rite tonu.

Te whakakore
Ma te whakamahi i te mono JavaScript matohi, ka taea te whakakore i nga raarangi matohi. Anei me pehea:
- Kia mahara kua utaina e koe te mono mataara, te Bootstrap JavaScript ranei.
- Tāpirihia he patene kati me te
.alert-dismissible
karaehe, he taapiri taapiri ki te taha matau o te mataaratanga me te whakanoho i te paatene kati. - I runga i te paatene kati, taapirihia te
data-bs-dismiss="alert"
huanga, e whakaohooho ana i te mahi JavaScript. Me mohio ki te whakamahi i te<button>
huānga me taua mea mo te whanonga tika puta noa i nga taputapu katoa. - Hei whakakorikori i nga matohi i te wa e whakakore ana i a raatau, me taapiri nga akomanga
.fade
me.show
nga karaehe.
Ka taea e koe te kite i tenei mahi me te whakaaturanga ora:
<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
huihuinga me te whakatakoto hotaka
focus()
ki te waahi e tika ana ki te wharangi. Mēnā kei te whakamahere koe ki te nuku arotahi ki tētahi huānga tauwhitiwhiti kore i te nuinga o te wā karekau i te aro, me whakauru
tabindex="-1"
ki te huānga.

Whakaranu rereke
Ka whakamahia tahi me $theme-colors
te hanga karaehe whakarereke horopaki mo o maatau matohi.
@mixin alert-variant($background, $border, $color) {

@include gradient-bg($background);

Te whanonga JavaScript
Arawhiti
Arawhiti huānga hei matohi
var alertList = document.querySelectorAll('.alert')
var alerts = [].slice.call(alertList).map(function (element) {
return new bootstrap.Alert(element)
})
Mo te kaupapa anake o te whakakore i te matohi, kaore e tika kia arawhiti-a-ringa te waahanga ma te JS API. Ma te whakamahi i data-bs-dismiss="alert"
te , ka arawhiti aunoa i te waahanga ka tika te whakakore.
Tirohia te waahanga keu mo etahi atu taipitopito.
Nga keu
Ka taea te whakakore me te data
huanga i runga i te paatene i roto i te matohi penei i te whakaaturanga i raro nei:
<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
i runga ranei i te paatene kei waho o te matohi ma te whakamahi i nga data-bs-target
mea e whakaatuhia ana i raro nei:
<button type="button" class="btn-close" data-bs-dismiss="alert" data-bs-target="#my-alert" aria-label="Close"></button>
Kia mahara ko te kati i te matohi ka tangohia mai i te DOM.
Nga tikanga
Tikanga | Whakaahuatanga |
---|---|
close |
Katia he matohi ma te tango mai i te DOM. Mena kei runga te .fade me .show nga karaehe i runga i te huānga, ka memeha haere te matohi i mua i te tangohanga. |
dispose |
Ka whakakore i te matohi o tetahi huānga. (Tangohia ai nga raraunga rongoa i te huānga DOM) |
getInstance |
Tikanga pateko e taea ai e koe te tiki i te tauira mataara e hono ana ki tetahi huānga DOM, ka taea e koe te whakamahi penei:bootstrap.Alert.getInstance(alert) |
getOrCreateInstance |
Aratuka pateko e whakahoki mai ana i tetahi tauira matohi e hono ana ki tetahi huānga DOM, ki te hanga i tetahi mea hou mena kaore i arawhitia. Ka taea e koe te whakamahi penei:bootstrap.Alert.getOrCreateInstance(element) |
var alertNode = document.querySelector('.alert')
var alert = bootstrap.Alert.getInstance(alertNode)
alert.close()
Nga huihuinga
Ko te mono matohi a Bootstrap e whakaatu ana i etahi huihuinga mo te hono ki te mahi mataara.
Takahanga | Whakaahuatanga |
---|---|
close.bs.alert |
Ka ahi tonu ina close karangahia te aratuka tauira. |
closed.bs.alert |
I puhia ina katia te matohi ka mutu nga whakawhitinga CSS. |
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()
})
