今天接触了这个模态窗口的使用方法，看到这个window.returnValue字段，查了查资料，弄清楚了这个方法的使用，贴出来只为记忆，无其他想法。
A界面 片段代码
function selectRegion(branchNo,mobileNo,userName){
var T_USER_ID="";
if(GetCookie("userId"+<%=confId%>)!= null) {
T_USER_ID=GetCookie("userId"+<%=confId%>);
}
var uri = "../Tree/BranchList.jsp?CompanyMobile=<%=companyMobile%>&BranchNo=" + branchNo + "&MobileNo=" + mobileNo + "&Name=" + userName+ "&T_USER_ID=<%=T_USER_ID%>";
var selResult = window.showModalDialog(uri,"","center:1;status:0;help:0;resized:1;dialogheight:26;dialogwidth:62")
//alert(selResult);
if(!selResult || selResult == "")
return;
var unitArray = selResult.split(',');
ReFundForm.BranchNo.value = unitArray[0];
ReFundForm.MobileNo.value = unitArray[1];
ReFundForm.Name.value = unitArray[2];
ReFundForm.Dept.value = unitArray[3];
}
B界面 片段代码
<script>
function selectIt(str) {
window.returnValue=str;
window.close();
}
</script>
...
提交<td width=52 height="23">
<input type="radio" value="V1" name="R1"onclick="selectIt('<%=s1%>,<%=s2%>, <%=s3%>,<%=s4%>')"> </td>
...
这自己的代码很难看懂，看看我在网上以下查的实例，清楚明白些，呵呵注：以下非原创。
fireForm.htm:点击“上传”按钮弹出内部窗口(showModalDialog),代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
<script language="javascript">
function onObjMore(url,name,height,width,formName) {
//window.alert(formName.file.type);
var feature = "dialogWidth:"+width+"px;dialogHeight:"+height+"px;scroll:yes;status:no;help:no;center:1";
var returnTarget = window.showModalDialog(url, name, feature);
if(returnTarget != undefined && returnTarget.length > 1) {
//document.location = returnTarget;
formName.file.value=returnTarget;
}
return false;
}
</script>
<link href="css/aljoin.css" rel="stylesheet" type="text/css">
</head>
<body>
<form name="proForm" method="post" action="">
<table width="400" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="93" height="25" style="white-space:nowrap " nowrap>文件</td>
<td width="307" height="25"><input name="file" type="text" id="file"></td>
</tr>
<tr>
<td height="25"> </td>
<td height="25"><input type="button" name="Submit" value="上传文件" onClick="onObjMore('upfile.htm','upfile',300,300,proForm)"></td>
</tr>
</table>
</form>
</body>
</html>
upfile.htm:点击”关闭”按钮返回window.returnValue值给opener,代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
<script language="javascript">
function exit() {
window.returnValue = "images/upload/2004080512.jpg";
window.close();
}
</script>
</head>
<body>
<input name="" type="button" value="关闭窗口" onClick="exit()">
</body>
</html>
