最近在网上看到了可以对Bootstrap模态框增加打开和关闭的动画效果，故记录一下。原文地址点这里      

此动画效果需要引入animate.css，可以在animate.css官方网址中点击下载animate.css. 这篇文章和这篇有对animate的简介。

 将如下代码放入JS文件全局引入：

//animate.css动画触动一次方法
$.fn.extend({animateCss: function (animationName) {var animationEnd = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend';this.addClass('animated ' + animationName).one(animationEnd, function() {$(this).removeClass('animated ' + animationName);});}});
/*** 显示模态框方法* @param targetModel 模态框选择器，jquery选择器* @param animateName 弹出动作* @ callback 回调方法*/
var modalShow = function(targetModel, animateName, callback){var animationIn = ["bounceIn","bounceInDown","bounceInLeft","bounceInRight","bounceInUp","fadeIn", "fadeInDown", "fadeInLeft", "fadeInRight", "fadeOutUp","fadeInDownBig", "fadeInLeftBig", "fadeOutRightBig", "fadeOutUpBig","flipInX","flipInY","lightSpeedIn","rotateIn","rotateInDownLeft","rotateInDownRight","rotateInUpLeft","rotateInUpRight","zoomIn","zoomInDown","zoomInLeft","zoomInRight","zoomInUp","slideInDown","slideInLeft","slideInRight", "slideInUp","rollIn"];if(!animateName || animationIn.indexOf(animateName)==-1){console.log(animationIn.length);var intRandom =  Math.floor(Math.random()*animationIn.length);animateName = animationIn[intRandom];}console.log(targetModel + " " + animateName);$(targetModel).show().animateCss(animateName);//callback.apply(this);
}
/*** 隐藏模态框方法* @param targetModel 模态框选择器，jquery选择器* @param animateName 隐藏动作* @ callback 回调方法*/
var modalHide = function(targetModel, animateName, callback){var animationOut = ["bounceOut","bounceOutDown","bounceOutLeft","bounceOutRight","bounceOutUp","fadeOut", "fadeOutDown", "fadeOutLeft", "fadeOutRight", "fadeOutUp","fadeOutDownBig", "fadeOutLeftBig", "fadeOutRightBig", "fadeOutUpBig","flipOutX","flipOutY","lightSpeedOut","rotateOut","rotateOutDownLeft","rotateOutDownRight","rotateOutUpLeft","rotateOutUpRight","zoomOut","zoomOutDown","zoomOutLeft","zoomOutRight","zoomOutUp","zoomOut","zoomOutDown","zoomOutLeft","zoomOutRight","zoomOutUp","slideOutDown","slideOutLeft","slideOutRight", "slideOutUp","rollOut"];if(!animateName || animationOut.indexOf(animateName)==-1){console.log(animationOut.length);var intRandom =  Math.floor(Math.random()*animationOut.length);animateName = animationOut[intRandom];}$(targetModel).children().click(function (e) {e.stopPropagation()});$(targetModel).animateCss(animateName);$(targetModel).delay(900).hide(1,function(){$(this).removeClass('animated ' + animateName);});//callback.apply(this);
}
var modalDataInit = function(info){//alert(info);//填充数据，对弹出模态框数据样式初始化或修改
}

以下是HTML代码：

<button type="button" class="btn btn-primary  test-btn" onclick="modalShow('#bigModal', '', modalDataInit('test'));">模态框测试
</button>
<div class="modal bs-example-modal-lg" onclick="modalHide('#bigModal', '');"
id="bigModal"><div class="modal-dialog modal-lg"><div class="modal-content"><div class="modal-header"><button type="button" onclick="modalHide('#bigModal', '');" class="close"data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button><h4 class="modal-title">模态框标题</h4></div><div class="modal-body"></div></div></div>
</div>

在刚开始或刷新页面时，点击对话框会自动隐藏，添加以下代码可以解决问题：

$(function(){$('#bigModal').children().click(function(e){e.stopPropagation()});
});

 每次打开和关闭模态框时会随机选择一个动画效果，也可以自己代码里写死效果，棒！
