  不设任何options参数的box(默认高200px,宽300px)

  普通设定高宽的box

  高宽自适应内容高宽的box

  不带预载动画的box

  延迟自动消失的box

  title自定义的box

  不带标题栏的的box

  不带标题栏关闭按钮的box

  带按钮和回调参数的box

  调用 Hongru.box.open(con,options)函数,参数con为弹出层主要内容,可以是html代码。options为一个object,可选参数目前有

  

复制代码 代码如下:

  {

  width:300 //自定义,弹出层主体(除边框和标题栏的宽度),为0时自适应。

  height:200//自定义,弹出层主体(除边框和标题栏的高度),为0时自适应。

  isPre:1 //true or false,是否有预加载背景图,

  time:0 //延迟自动关闭时间,秒为单位,0时不触发

  title:'' //自定义title

  isBar:1 //true or false,是否有标题栏

  isShut:1 //是否有关闭按钮

  }

  另 Hongru.box.ask(con,options,surecall,cancelcall)为带按钮的提示框,带回调函数前两个参数同上,后两个参数分别为‘确认'和‘取消'的回调函数

  其中加入了透明度渐变和大小渐变,透明度渐变主体函数如下:

  

复制代码 代码如下:

  show sourceview sourceprint?alphaAnim:function(obj,destination,direction){

  var opacity = Math.round(obj.style.opacity*100);

  if(opacity == destination){

  clearInterval(obj.animing);

  if(direction == -1){

  obj.style.display='none';

  obj == box?Hongru.box.alpha(mask,-1,0):content.innerHTML=box.style.backgroundImage='';

  }else{

  curOptions = {width:_width,height:_height,isPre:isPreload}

  obj == mask?this.alpha(box,1,100):Hongru.box.fill(_content,curOptions);

  }

  }else{

  var n=Math.ceil((opacity+((destination-opacity)*.5))); n=n==1?0:n;

  obj.style.opacity=n/100;

  obj.style.filter='alpha(opacity='+n+')';

  }

  },

  box大小渐变函数体如下:

  

复制代码 代码如下:

  show sourceview sourceprint?sizeAnim:function(obj,width,otherW,wFlag,height,otherH,hFlag){

  var objW = obj.offsetWidth-otherW, objH = obj.offsetHeight-otherH;

  if(objW == width && objH == height){

  clearInterval(obj.sizing);

  box.style.backgroundImage='none';

  content.style.display='block';

  }else{

  if(objW!=width){

  var n = objW+((width-objW)*.5);

  obj.style.width = wFlag?Math.ceil(n)+'px':Math.floor(n)+'px';

  }

  if(objH!=height){

  var n = objH+((height-objH)*.5);

  obj.style.height = hFlag?Math.ceil(n)+'px':Math.floor(n)+'px';

  }

  this.pos();

  }

  },
