下面是showModalDialog/showModelessDialog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.关闭刷新父窗口,希望对象我这样的WEB开发的菜鸟有所帮助.




(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.

<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


}

function retrunValue()




...{


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


window.returnValue=s;


window.close();


}


//-->


</script>




----------------------------


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

if(k == 1)//判断是否刷新




...{


alert('刷新');


window.location.reload();


}


}


//-->


</script>

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


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

<BODY>


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




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


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




</BODY>


</HTML>






<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>




--------------------------


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>
