单击时，下面的脚本应显示如下模式对话框：http://codepen.io/dfitzy/pen/yeoeGO如何在页面加载时显示弹出窗口，而不是单击按钮时弹出窗口？我尝试使用onload，但没有发生任何事情。有任何想法吗？加载popup onload？
(function(){
var $content = $('.modal_info').detach();
$('.open_button').on('click', function(e){
modal.open({
content: $content,
width: 540,
height: 270,
});
$content.addClass('modal_content');
$('.modal, .modal_overlay').addClass('display');
$('.open_button').addClass('load');
});
}());
var modal = (function(){
var $close = $('<button role="button" class="modal_close" title="Close"><span></span></button>');
var $content = $('<div class="modal_content"/>');
var $modal = $('<div class="modal"/>');
var $window = $(window);
$modal.append($content, $close);
$close.on('click', function(e){
$('.modal, .modal_overlay').addClass('conceal');
$('.modal, .modal_overlay').removeClass('display');
$('.open_button').removeClass('load');
e.preventDefault();
modal.close();
});
return {
center: function(){
var top = Math.max($window.height() - $modal.outerHeight(), 0)/2;
var left = Math.max($window.width() - $modal.outerWidth(), 0)/2;
$modal.css({
top: top + $window.scrollTop(),
left: left + $window.scrollLeft(),
});
},
open: function(settings){
$content.empty().append(settings.content);
$modal.css({
width: settings.width || 'auto',
height: settings.height || 'auto'
}).appendTo('body');
modal.center();
$(window).on('resize', modal.center);
},
close: function(){
$content.empty();
$modal.detach();
$(window).off('resize', modal.center);
}
};
}());
</script>
你可以试试这个=> $（ 'open_button。'）准备就绪（函数（E）{...}）; –
