父窗口与弹出窗口之间的传值问题?

在Web开发中,常常要用到两个窗口之间互相传值。下面谈谈父子窗口之间的传值:
一:使用Open开启子窗口
1:单值传递

通过open开启的子窗口比较好处理。

页面窗口1.html代码:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body>

<form name="dForm" id="dForm" method="post" onsubmit="return dFormCK();" action="abc.php">

<input type="text" size="30" name="p" id="p" value=""/>

</form>

<a href="javascript:void(0)" onclick="window.open('2.html','child','width=400,height=300,left=200,top=200');">打开子窗口</a>

</body>

</html>

Open后弹出的子窗口2.html:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<base target="_self"> 

<body>

<input type="button" onclick="JavaScript:window.opener.document.getElementById('p').value='ok';window.close();" value="确定">

</body>

2:多值传递

多值的值的传递与单值传递是一模一样的。

页面窗口1.html代码:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body>

<form name="dForm" id="dForm" method="post" onsubmit="return dFormCK();" action="abc.php">

<input type="text" size="30" name="p0" id="p0" value=""/><br />

<input type="text" size="30" name="p1" id="p1" value=""/>

</form>

<a href="javascript:void(0)" onclick="window.open('2.html','child','width=400,height=300,left=200,top=200');">打开子窗口</a>

</body>

</html>

Open后弹出的子窗口2.html:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<base target="_self"> 

<body>

<input type="button" onclick="JavaScript:window.opener.document.getElementById('p0').value='值一';window.opener.document.getElementById('p1').value='值二';window.close();" value="确定">

</body>

二:使用showModalDialog开启子窗口
1:单值传递

由于window.showModalDialog 打开的子窗口,不支持 window.opener属性,因此,我们使用一参数方式来传值。具体操作如下:

页面文件1.html

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script language="JavaScript">

<!--

function   show() 



  var   a=window.showModalDialog('2.html',"pwin",'dialogWidth:480px;dialogHeight:460px;center:yes;resizable:no;scroll:no');

  document.dForm.p.value=a;

  }

//-->

</script>

<body>

<form name="dForm" id="dForm" method="post" onsubmit="return dFormCK();" action="abc.php">

<input type="text" size="30" name="p" id="p" value=""/>

</form>

<a href="javascript:void(0);" onclick="show();">ShowModelDialog</a>

</body>

</html>

弹出的子窗口2.html:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<base target="_self"> 

<body>

<input type="button" onclick="JavaScript:window.returnValue='这是返回的值';window.close();" value="确定">

<input type="button" onclick="JavaScript:window.returnValue='';window.close();" value="取消">

</body>

2:多值传递

多值的传递方法同第一点,也是通过一个参数来传递,由于是多个值,所以我们自然而然地想到要用数组来传递。

页面文件11.html

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script language="JavaScript">

<!--

function   show() 

  { 

    var a=new Array(3);

    var   a=window.showModalDialog('22.html',"pwin",'dialogWidth:480px;dialogHeight:460px;help:no;center:yes;resizable:no;scroll:no');

    document.dForm.p0.value=a[0];

    document.dForm.p1.value=a[1];

    document.dForm.p2.value=a[2];

  }

//-->

</script>

<body>

<form name="dForm" id="dForm" method="post" onsubmit="return dFormCK();" action="abc.php">

<input type="text" size="30" name="p0" id="p0" value=""/><br />

<input type="text" size="30" name="p1" id="p1" value=""/><br />

<input type="text" size="30" name="p2" id="p2" value=""/>

</form>

<a href="javascript:void(0);" onclick="show();">ShowModelDialog</a>

</body>

</html>

弹出子窗窗口22.html

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<base target="_self"> 

<body> 

<input type="button" onclick="JavaScript:var s=Array(3);s[0]='abc';s[1]='bcd';s[2]='cde'; window.returnValue=s;window.close();" value="确定">

</body>
