子窗体与父窗体传值示例js代码

//返回值给父窗体 
function returnParent(value) {//获取子窗体返回值 
var parent = window.dialogArguments; //获取父页面 
//parent.location.reload(); //刷新父页面 
if (parent != null && parent != "undefined") { 
window.returnValue = value; //返回值 
window.close(); //关闭子页面 
} 
//window.opener.document.getElementById("ActivityPic");//直接操作父窗体元素 
//$(selector, window.parent.document);用于框架类页面 
//$(selector, window.opener.document);这个适合单独打开的页面 
return; 
} 
//打开模式子窗体，获取返回值进行操作 
function showModalOnly(me, url) { //弹出窗体 ,单选 
var hidden = document.getElementById(me); //获取隐藏的控件 
if (hidden != null && hidden.value != null && hidden.value.length > 0) { 
alert("此处为单选，请先删除已有的选项，再次尝试选择。"); 
return; 
} 
var reValue = window.showModalDialog(url, window, "dialogHeight:500px; dialogWidth:987px; status:off; scroll:auto");

return; //如果返回值为空，就返回 
} 
var index = reValue.split("^"); //分割符 ^ 的位置 
if (index[0] == null || index[0] == "undefined" || index[0].length < 1) { 
return;
