以前觉得自己手写一个类似layui的弹出层是挺遥远的事,因为完全没有头绪,即便在layui官网知道layui使用的都是C3动画
之前试过控制width:0;height:0来做动画,结果惨不忍睹,直到几天前灵机一动联想到了tranform的scale属性,才稍微触及到了皮毛
为了不添加格外的HTML结构,所以弹出层也是动态生成
layui弹出框和遮罩层是同级结构,而我把弹出框放遮罩层里了,所以关闭时要用animationend来监听,弹出框做完动画后才删除遮罩层
确认框confirm之前也想跟原生confirm一样,通过返回布尔值来进行流程控制,结果为undefined,因为在调用时就已经返回了,而不是点了“确定“”才有返回值,这里和原生的一样,所以跟layui一样使用callback
HTML
<input type="button" value="模拟layui弹出层" id="btn-alert">
JS
function MsgAlert() {
this.alert = function (msg, time) {
var delay = time || 1200,
that = this;
$('body').append('<div id="msgAlertMask">\n' +

' <div class="title">\n' +
' <span class="close">×</span>\n' +

' <div class="content">' + msg + '</div>\n' +
' </div>\n' +
'</div>');
$('#msgAlert').addClass('alert-show');
$('#msgAlert').on('click', '.close', function () {
that.destroy();
});
setTimeout(function () {
that.destroy();
}, delay);
};
this.confirm = function (msg, callback) {
var that = this;
$('body').append('<div id="msgAlertMask">\n' +
