嗨,你有合适的js吗?
假设您正在尝试使用 twitter bootstrap 的警报功能?
!function ($) {
"use strict"; // jshint ;_;
/* ALERT CLASS DEFINITION
* ====================== */
var dismiss = '[data-dismiss="alert"]'
, Alert = function (el) {
$(el).on('click', dismiss, this.close)
}
Alert.prototype.close = function (e) {
var $this = $(this)
, selector = $this.attr('data-target')
, $parent
if (!selector) {
selector = $this.attr('href')
selector = selector && selector.replace(/.*(?=#[^\s]*$)/, '') //strip for ie7
}
$parent = $(selector)
e && e.preventDefault()
$parent.length || ($parent = $this.hasClass('alert') ? $this : $this.parent())
$parent.trigger(e = $.Event('close'))
if (e.isDefaultPrevented()) return
$parent.removeClass('in')
function removeElement() {
$parent
.trigger('closed')
.remove()
}
$.support.transition && $parent.hasClass('fade') ?
$parent.on($.support.transition.end, removeElement) :
removeElement()
}
/* ALERT PLUGIN DEFINITION
* ======================= */
var old = $.fn.alert
$.fn.alert = function (option) {
return this.each(function () {
var $this = $(this)
, data = $this.data('alert')
if (!data) $this.data('alert', (data = new Alert(this)))
if (typeof option == 'string') data[option].call($this)
})
}
$.fn.alert.Constructor = Alert
/* ALERT NO CONFLICT
* ================= */
$.fn.alert.noConflict = function () {
$.fn.alert = old
return this
}
/* ALERT DATA-API
* ============== */
$(document).on('click.alert.data-api', dismiss, Alert.prototype.close)
}(window.jQuery);
你是如何在你的应用程序中使用 twitter 引导程序的?
您是否包含//= require bootstrap
在您的 application.js 文件中?这是我喜欢使用 gem bootstrap-sass 所必需的(依赖于 gem sass-rails)
