子窗體與父窗體傳值範例js程式碼_javascript技巧

複製程式碼 程式碼如下:

//回傳值給父窗體
function returnParentvalue ) {//取得子窗體回傳值
var parent = window.dialogArguments; //取得父頁
//parent.location.reload(); //刷新父頁
if (parent ! = null && parent != "undefined") {
window.returnValue = value; //傳回值
window.close(); //關閉子頁面
}
//window.opener .document.getElementById("ActivityPic");//直接操作父窗體元素
//$(selector, window.parent.document);用於框架類別頁面
//$(selector, window. opener.document);這個適合單獨開啟的頁面
return;
}
//開啟模式子窗體，取得回傳值進行操作
function showModalOnly(me, url) { //彈出窗體,單選
var hidden = document.getElementById(me); //取得隱藏的控制項
if (hidden != null && hidden.value != null && hidden.value.length > 0) {
alert("此處為單選，請先刪除已有的選項，再嘗試選擇。");
return;
}
var reValue = window.showModalDialog(url, window, "dialogHeight:500px; dialogWidth:987px; status:off; scroll:auto");
if (reValue == null || reValue == "undefined" || reValue == "") {
return; //如果回傳值為空，就回傳
}
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('&'); //為隱藏控制項賦值
var view = index[1].split('&'); //顯示值
var content = ""; //需要加入check中的內容
if (hid != null && hid.length == 2) {
var i = 0;
if (hid[i] != "undefined" && hid[i] != "" && view[i 1] ! = "undefined" && view[i 1] != "") {
content = '

"'" hid[i] "'," "'" me "'" ');" />

' view[i 1] '

';
hidden.value = hid[ i]; //為隱藏控制項賦值
var c = document.getElementById("check" me);
c.innerHTML = content;
return;
}
}
alert("請只選擇一條資料。 ");
return;
}
function openUploadWindow(url, width, height,left,top) {
if(width==null) width=987;
if (height = = null) height = 500;
if (left == null) left = 200;
if (top == null) top = 200;
//window.open(url, 'newwindow', 'height=' height ',width=' width ',top=200,left=200,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no');
window.showModalDialog(url, window, "dialogHeight:" height "px; dialogWidth:" width "px;status:off; scroll:auto;dialogLeft:" left "px;dialogTop:" top "px"); }
