使用javascript打开模态对话框,想学习showModalDialog使用方法的朋友可以参考下。
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'//www.jb51.net', '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 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> 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: http://adandelion.cnblogs.com/articles/252137.html <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");

//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> |
