啥也不说,先上图,有图有真相 ????

现在绝大多数网站都不用自带的alert和confirm了,因为界面太生硬了。因此这个插件就这样产生了…

来看插件的实现代码吧:


(function () {
$.MsgBox = {
Alert: function (title, msg) {
GenerateHtml("alert", title, msg);
btnOk(); //alert只是弹出消息,因此没必要用到回调函数callback
btnNo();
},
Confirm: function (title, msg, callback) {
GenerateHtml("confirm", title, msg);
btnOk(callback);
btnNo();
}
}

//生成Html
var GenerateHtml = function (type, title, msg) {

var _html = "";

_html += '<div id="mb_box"></div><div id="mb_con"><span id="mb_tit">' + title + '</span>';
_html += '<a id="mb_ico">x</a><div id="mb_msg">' + msg + '</div><div id="mb_btnbox">';

if (type == "alert") {
_html += '<input id="mb_btn_ok" type="button" value="确定" />';
}
if (type == "confirm") {
_html += '<input id="mb_btn_ok" type="button" value="确定" />';
_html += '<input id="mb_btn_no" type="button" value="取消" />';
}
_html += '</div></div>';

//必须先将_html添加到body,再设置Css样式
$("body").append(_html); GenerateCss();
}

//生成Css
var GenerateCss = function () {

$("#mb_box").css({ width: '100%', height: '100%', zIndex: '99999', position: 'fixed',
filter: 'Alpha(opacity=60)', backgroundColor: 'black', top: '0', left: '0', opacity: '0.6'
});

$("#mb_con").css({ zIndex: '999999', width: '400px', position: 'fixed',
backgroundColor: 'White', borderRadius: '15px'
});

$("#mb_tit").css({ display: 'block', fontSize: '14px', color: '#444', padding: '10px 15px',
backgroundColor: '#DDD', borderRadius: '15px 15px 0 0',
borderBottom: '3px solid #009BFE', fontWeight: 'bold'
});

$("#mb_msg").css({ padding: '20px', lineHeight: '20px',
borderBottom: '1px dashed #DDD', fontSize: '13px'
});

$("#mb_ico").css({ display: 'block', position: 'absolute', right: '10px', top: '9px',
border: '1px solid Gray', width: '18px', height: '18px', textAlign: 'center',
lineHeight: '16px', cursor: 'pointer', borderRadius: '12px', fontFamily: '微软雅黑'
});

$("#mb_btnbox").css({ margin: '15px 0 10px 0', textAlign: 'center' });
$("#mb_btn_ok,#mb_btn_no").css({ width: '85px', height: '30px', color: 'white', border: 'none' });
