Alertify.js which helped me resolve my issues regarding prompts, alerts, confirms, etc in iOS7.
1.alertify插件功能
主要实现提示功能，用于代替js中的alert,confirm,prompt，显示友好的提示框
2.alertify使用方法
1.使用的文件
主要使用三个文件，两个css（alertify.core.css，alertify.default.css），用于设置提示框的样式。一个js（alertify.min.js或alertify.js），用于实现提示框的功能。
2.实现提示框代码
alertify使用非常简单，主要步骤为：初始化（初始化alertify）-》绑定(绑定事件)
如实现简单的提示框、确认框和提示框
var $ = function (id) { return document.getElementById(id); }, //初始化操作 reset = function () { alertify.set({ labels : { ok : "确认", cancel : "取消" }, delay : 5000, buttonReverse : false, buttonFocus : "ok" }); }; //绑定 $("alert").onclick = function () { reset(); alertify.alert("提示框"); return false; }; //绑定 $("confirm").onclick = function () { reset(); alertify.confirm("确认框", function (e) { if (e) { alertify.success("点击确认"); } else { alertify.error("点击取消"); } }); return false; }; //绑定 $("prompt").onclick = function () { reset(); alertify.prompt("提示输入框", function (e, str) { if (e) { alertify.success("点击确认，输入内容为: " + str); } else { alertify.error("点击取消"); } }, "默认值"); return false; };
显示结果(输入提示框)：
4.alertify修改样式
主要是修改两个css文件(alertify.core.css，alertify.default.css)，也可以覆盖使用。如在页面中加入
.alertify{ width:350px; margin-left: -205px; border:2px solid #4ba9e6; background:#f3faff; border-radius:0; }
修改后显示结果：
alertify使用说明
alertify是由html5+css3开发的插件，所以完美的支持html5+css3的浏览器。在测试过程过，alertify在chrome与火狐浏览器中显示效果是完美的，但是在ie8一下，显示效果有所不同，如圆角框、阴影、动画特效等不会显示。
