javascript showModalDialog模态对话框使用说明

  1. 标准的方法

  

复制代码 代码如下:

  <script type="text/javascript">

  function openWin(src, width, height, showScroll){

  window.showModalDialog (src,"","location:No;status:No;help:No;dialogWidth:"+width+";dialogHeight:"+height+";scroll:"+showScroll+";");

  }

  </script>

  例:<span style="CURSOR: pointer" onclick="openWin'http://www.glzy8.com', '500px', '400px', 'no')">点击</span>

  2. 要注意的是,Firefox并不支持该功能,它支持的语法是

  

复制代码 代码如下:

  window.open

  ('openwin.html','newWin', 'modal=yes, width=200,height=200,resizable=no, scrollbars=no' );

  3. 如何自动判断浏览器

  

复制代码 代码如下:

  <input type="button" value="打开对话框" onclick="showDialog('#')"/>

  <SCRIPT LANGUAGE="JavaScript">

  <!--

  function showDialog(url)

  {

  if( document.all ) //IE

  {

  feature="dialogWidth:300px;dialogHeight:200px;status:no;help:no";

  window.showModalDialog(url,null,feature);

  }

  else

  {

  //modelessDialog可以将modal换成dialog=yes

  feature ="width=300,height=200,menubar=no,toolbar=no,location=no,";

  feature+="scrollbars=no,status=no,modal=yes";

  window.open(url,null,feature);

  }

  }

  //-->

  </SCRIPT>

  4. 在IE中,模态对话框会隐藏地址栏,而在其他浏览器则不一定

  【注意】在谷歌浏览器中,这个模态的效果也会失效。

  5. 一般在弹出对话框的时候,我们都希望整个父页面的背景变为一个半透明的颜色,让用户看到后面是不可以访问的

  而关闭对话框之后又希望还原

  这是怎么做到的呢?

  

复制代码 代码如下:

  ///显示某个订单的详细信息,通过一个模态对话框,而且屏幕会变颜色

  function ShowOrderDetails(orderId) {

  var url = "details.aspx?orderID=" + orderId;

  //$("body").css("filter", "Alpha(Opacity=20)");

  //filter:Alpha(Opacity=50)

  $("body").addClass("body1");

  ShowDetailsDialog(url, "600px", "400px", "yes");

  $("body").removeClass("body1");

  }

  另外,有一个样式表定义

  

复制代码 代码如下:

  .body1

  {

  background-color:#999999;

  filter:Alpha(Opacity=40);

  }

  6. 如何在页面之间传递数值

  showModalDialog 传值及刷新

  (一)showModalDialog使用例子,父窗口向子窗口传递值,子窗口设置父窗口的值,子窗口关闭的时候返回值到父窗口.

  farther.html

  

复制代码 代码如下:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

  <HTML>

  <HEAD>

  <TITLE>New Document </TITLE>

  <META content="EditPlus" name="Generator">

  <META content="" name="Author">

  <META content="" name="Keywords">

  <META content="" name="Description">

  <script language="javascript">

  <!--

  function openChild(){

  var k = window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");

  if(k != null)

  document.getElementById("txt11").value = k;

  }

  //-->

  </script>

  </HEAD>

  <BODY>

  <FONT face="宋体"></FONT>

  <br>

  传递到父窗口的值:<input id="txt9" type="text" value="3333333333333" name="txt9"><br>

  返回的值:<input id="txt11" type="text" name="txt11"><br>

  子窗口设置的值:<input id="txt10" type="text" name="txt10"><br>

  <input id="Button1" onclick="openChild()" type="button" value="openChild" name="Button1">

  </BODY>

  </HTML>

  child.html

  

复制代码 代码如下:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

  <HTML>

  <HEAD>

  <TITLE>New Document </TITLE>

  <META content="EditPlus" name="Generator">

  <meta http-equiv="Pragma" content="no-cache">

  </HEAD>

  <BODY>

  <FONT face="宋体"></FONT>

  <br>

  父窗口传递来的值:<input id="txt0" type="text" name="txt0"><br>

  输入要设置父窗口的值:<input id="txt1" type="text" name="txt1"><input id="Button1" onclick="setFather()" type="button" value="设置父窗口的值" name="Button1"><br>

  输入返回的值:<input id="txt2" type="text" name="txt2"><input id="Button2" onclick="retrunValue()" type="button" value="关闭切返回值" name="Button2">

  <input id="Button3" onclick="" type="button" value="关闭刷新父窗口" name="Button3">

  <script language="javascript">

  <!--

  var k=window.dialogArguments;

  //获得父窗口传递来的值

  if(k!=null)

  {

  document.getElementById("txt0").value = k.document.getElementById("txt9").value;

  }

  //设置父窗口的值

  function setFather()

  {

  k.document.getElementById("txt10").value = document.getElementById("txt1").value

  }

  //设置返回到父窗口的值

  function retrunValue()

  {

  var s = document.getElementById("txt2").value;

  window.returnValue=s;

  window.close();

  }

  //-->

  </script>

  </BODY>

  </HTML>

  说明:

  由于showModalDialog缓存严重,下面是在子窗口取消客户端缓存的设置.也可以在服务器端取消缓存,参考:

  <meta http-equiv="Expires" CONTENT="0">

  <meta http-equiv="Cache-Control" CONTENT="no-cache">

  <meta http-equiv="Pragma" CONTENT="no-cache">

  二)下面是关闭刷新父窗口的例子

  farther.html

  

复制代码 代码如下:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

  <HTML>

  <HEAD>

  <TITLE>New Document </TITLE>

  <META NAME="Generator" CONTENT="EditPlus">

  <META NAME="Author" CONTENT="">

  <META NAME="Keywords" CONTENT="">

  <META NAME="Description" CONTENT="">

  <script language="javascript">

  <!--

  function openChild()

  {

  var k = window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");

  if(k == 1)//判断是否刷新

  {

  alert('刷新');

  window.location.reload();

  }

  }

  //-->

  </script>

  </HEAD>

  <BODY>

  <br>

  传递到父窗口的值:<input id="txt9" type="text" value="3333333333333" NAME="txt9"><br>

  <input type="button" value="openChild" onclick="openChild()" ID="Button1" NAME="Button1">

  </BODY>

  </HTML>

  child.html

  

复制代码 代码如下:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

  <HTML>

  <HEAD>

  <TITLE>New Document </TITLE>

  <META content="EditPlus" name="Generator">

  <META content="" name="Author">

  <META content="" name="Keywords">

  <META content="" name="Description">

  <meta http-equiv="Expires" content="0">

  <meta http-equiv="Cache-Control" content="no-cache">

  <meta http-equiv="Pragma" content="no-cache">

  </HEAD>

  <BODY>

  <FONT face="宋体"></FONT>

  <br>

  父窗口传递来的值:<input id="txt0" type="text" name="txt0"><br>

  <input id="Button1" onclick="winClose(1)" type="button" value="关闭刷新父窗口" name="Button1">

  <input id="Button2" onclick="winClose(0)" type="button" value="关闭不刷新父窗口" name="Button2">

  <script language="javascript">

  <!--

  var k=window.dialogArguments;

  //获得父窗口传递来的值

  if(k!=null)

  {

  document.getElementById("txt0").value = k.document.getElementById("txt9").value;

  }

  //关闭窗口返回是否刷新的参数.

  function winClose(isRefrash)

  {

  window.returnValue=isRefrash;

  window.close();

  }

  //-->

  </script>

  </BODY>

  </HTML>

  说明

  1.下面是取消客户端缓存的:

  <meta http-equiv="Expires" CONTENT="0">

  <meta http-equiv="Cache-Control" CONTENT="no-cache">

  <meta http-equiv="Pragma" CONTENT="no-cache">

  也可以在服务器端取消缓存,参考:

  http://adandelion.cnblogs.com/articles/252137.html

  2.向父窗口传递阐述在ASP.NET中也可以是用aaa.aspx?id=1的方式传递.

  3.不刷新父窗口的话在父窗口中直接这样一来设置可以.

  <script>

  window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");

  </script>

  4.在子窗口中若要提交页面的话要加入:,这样就不会打开新窗口了.

  <head>

  <base target="_self">

  </HEAD>
