基于Jquery的开发个代阴影的对话框效果代码

复制代码 代码如下:

  <script type="text/javascript" src="http://img.zzl.com/script/jquery/jquery-1.4.2.min.js"></script>

  <script type="text/javascript">

  $(function() {

  $("#open").click(function() {

  openDialog(a1); //调用,直接写上DIV的ID即可

  });

  });

  var openDialog = function(o) {

  var dialog = new zzlDialog(o);

  dialog.open();

  }

  var zzlDialog = function(o) {

  this.init = function() {

  /* 对话框初始化 */

  var XBox = '\

  <div id="mask"/>\

  <div id="wai">\

  </div>\

  <div id="nie">\

  <table>\

  <thead>\

  <tr>\

  <td>\

  阴影弹出框\

  </td>\

  <td>\

  </td>\

  </tr>\

  </thead>\

  <tbody>\

  <tr>\

  <td colspan="2">' + $(o).html() + '\

  </td>\

  </tr>\

  </tbody>\

  </table>\

  </div>\

  ';

  $(document.body).append(XBox);

  };

  this.cssInit = function() {

  /* css初始化 */

  $("#wai").css({ "padding": "10px", "background": "#000", "filter": "Alpha(Opacity='50')", "position": "absolute" });

  $("#nie").css({ "position": "absolute", "z-index": "1000" });

  $("#nie>table").css({ "border": "1px solid rgb(55,119,188)", "border-collapse": "collapse", "background": "#fff" });

  $("#nie>table>thead>tr").css({ "background": "rgb(0,94,172)", "color": "#fff", "height": "30px", "font-size": "14px", "font-weight": "bold" });

  $("#nie>table").find("td").css({ "padding": "5"});

  /* 内部主体定位 */

  $("#nie").css({ "top": "50px" });

  $("#nie").css({ "left": "50px" });

  /* 关闭按钮 */

  var $close = $("#nie>table>thead").find("td").next("td");

  $close.html("<span>关闭</span>");

  $close.css({ "text-align": "right", "padding-right": "5px" });

  $close.find("span").css({ "font-weight": "normal", "cursor": "hand" });

  $close.find("span").click(function() { new zzlDialog().closes(); });

  /* 外部阴影添加 ,及位置和大小由内部内容来控制 */

  $("#wai").css({ "width": ($("#nie>table").width() + 16) + "px", "height": ($("#nie>table").height() + 16) + "px" });

  $("#wai").css({ "top": $("#nie").position().top - 8 + "px", "left": $("#nie").position().left - 8 + "px", "z-index": $("#nie").css("z-index") });

  // $("#wai").corner("5px"); //圆角

  };

  this.open = function() {

  this.init();

  this.cssInit();

  this.shadow();

  };

  this.shadow = function() {

  this.event_b_show();

  if (window.attachEvent) {

  window.attachEvent('onresize', this.event_b);

  window.attachEvent('onscroll', this.event_b);

  }

  else {

  window.addEventListener('resize', this.event_b, false);

  window.addEventListener('scroll', this.event_b, false);

  }

  };

  this.event_b = function() {

  var oShadow = $('#mask');

  if (oShadow.css("display") != "none") {

  if (this.event_b_show) {

  this.event_b_show();

  }

  }

  };

  this.closes = function() {

  var oShadow = $('#mask');

  oShadow.css({ 'display': 'none' });

  $("#wai").remove();

  $("#nie").remove();

  };

  this.event_b_show = function() {

  var oShadow = $('#mask');

  oShadow.css({ 'position': 'absolute', 'display': '', 'opacity': '0.1', 'filter': 'alpha(opacity=10)', 'background': '#000' });

  var sClientWidth = parent ? parent.document.body.offsetWidth : document.body.offsetWidth;

  var sClientHeight = parent ? parent.document.body.offsetHeight : document.body.offsetHeight;

  var sScrollTop = parent ? (parent.document.body.scrollTop + parent.document.documentElement.scrollTop) : (document.body.scrollTop + document.documentElement.scrollTop);

  oShadow.css({ 'top': '0px', 'left': '0px', 'width': sClientWidth + "px", 'height': (sClientHeight + sScrollTop) + "px" });
