twitter-bootstrap - Bootstrap 4小吃店/吐司

问题描述

我正在尝试使用 Bootstrap 4 创建一个小吃店/吐司版本。我从 w3schools的本教程开始。

更新：我试图为 Bootstrap 4 实现一个自定义的小吃店或烤面包，但现在没有必要，因为 Bootstrap 4 包含了 4.2 版中的这个选项，正如@Zim 所说。

标签： twitter-bootstrapnotificationsbootstrap-4toastsnackbar

解决方案

我（强调 = 完全公开）为 toasts 组件创建了一个 jQuery 插件，以使它们更易于使用，可以在此处找到 repo 。目的是能够通过 JavaScript 即时调用 toast。

吐司

$.toast({
  title: 'Toast',
  subtitle: '11 mins ago',
  content: 'Hello, world! This is a toast message.',
  type: 'info',
  delay: 5000
});

小吃

$.toast({
  title: 'A small bitesize snack, not a toast!',
  type: 'info',
  delay: 5000
});

现场示例

(function(b){b.toast=function(a,h,g,l,k){b("#toast-container").length||(b("body").prepend('<div id="toast-container" aria-live="polite" aria-atomic="true"></div>'),b("#toast-container").append('<div id="toast-wrapper"></div>'));var c="",d="",e="text-muted",f="",m="object"===typeof a?a.title||"":a||"Notice!";h="object"===typeof a?a.subtitle||"":h||"";g="object"===typeof a?a.content||"":g||"";k="object"===typeof a?a.delay||3E3:k||3E3;switch("object"===typeof a?a.type||"":l||"info"){case "info":c="bg-info";
f=e=d="text-white";break;case "success":c="bg-success";f=e=d="text-white";break;case "warning":case "warn":c="bg-warning";f=e=d="text-white";break;case "error":case "danger":c="bg-danger",f=e=d="text-white"}a='<div class="toast" role="alert" aria-live="assertive" aria-atomic="true" data-delay="'+k+'">'+('<div class="toast-header '+c+" "+d+'">')+('<strong class="mr-auto">'+m+"</strong>");a+='<small class="'+e+'">'+h+"</small>";a+='<button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">';
a+='<span aria-hidden="true" class="'+f+'">&times;</span>';a+="</button>";a+="</div>";""!==g&&(a+='<div class="toast-body">',a+=g,a+="</div>");a+="</div>";b("#toast-wrapper").append(a);b("#toast-wrapper .toast:last").toast("show")}})(jQuery);


const TYPES = ['info', 'warning', 'success', 'error'],
      TITLES = {
        'info': 'Notice!',
        'success': 'Awesome!',
        'warning': 'Watch Out!',
        'error': 'Doh!'
      },
      CONTENT = {
        'info': 'Hello, world! This is a toast message.',
        'success': 'The action has been completed.',
        'warning': 'It\'s all about to go wrong',
        'error': 'It all went wrong.'
      };

function show_random_toast()
{
  let type = TYPES[Math.floor(Math.random() * TYPES.length)],
      title = TITLES[type],
      content = CONTENT[type];

  $.toast({
    title: title,
    subtitle: '11 mins ago',
    content: content,
    type: type,
    delay: 5000
  });
}

function show_random_snack()
{
  let type = TYPES[Math.floor(Math.random() * TYPES.length)],
      content = CONTENT[type].replace('toast', 'snack');
      
  $.toast({
    title: content,
    type: type,
    delay: 5000
  });
}
#toast-container {
    position: sticky;
    z-index: 1055;
    top: 0
}

#toast-wrapper {
    position: absolute;
    top: 0;
    right: 0;
    margin: 5px
}

#toast-container > #toast-wrapper > .toast {
    min-width: 150px
}

#toast-container > #toast-wrapper > .toast >.toast-header strong {
    padding-right: 20px
}
