子窗体与父窗体传值示例js代码_javascript技巧

//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");
if (reValue == null || reValue == "undefined" || reValue == "") {
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 return;
}
var hid = index[0].split('&'); //为隐藏控件赋值
var view = index[1].split('&'); //显示值
var content = ""; //需要添加到check中的内容
if (hid != null && hid.length == 2) {
var i = 0;
if (hid[i] != "undefined" && hid[i] != "" && view[i + 1] != "undefined" && view[i + 1] != "") {
content += '

' + view[i + 1] + '

';
hidden.value = hid[i]; //为隐藏控件赋值
var c = document.getElementById("check" + me);
c.innerHTML += content;
return;
}
}
alert("请只选择一条数据。");
return;
}
