问题描述

这是我的场景

i我在javascript中有一个包含数据的数组变量。

同时刷新或回发这些变量丢失了，我无法在刷新/回发后获得变量中的那些数据

请告诉我如何将这些变量存储回服务器之前重新打包并带回来

注意：我使用asp.net作为服务器端

谢谢，

Raj

解决方案

你可以用Cookie做到......但问题是你不能在Cookie中存储数组.....你有将它存储为字符串

解决方案

you can do it using Cookie ...... but the problem is you can''t store Array in Cookie ..... you have to store it as String

Thanks JANA ,

but what i am trying is
while onload and onunload the array array object is stored in hdnfield
and on load, its got restored in the javascript
...
window.onload = setChilds("htmHdnChild");

...
<body onunload = "getChilds(''htmHdnChild'')">

function setChilds(HdnID)
{
alert("in set child");
var hdnCtrl = document.all(HdnID);
if (hdnCtrl!=null)
{
myChild = hdnCtrl;
alert(myChild.length);
}
}

function getChilds(HdnID)
{
//alert("in Get child");
var hdnCtrl = document.all(HdnID);
alert(myChild.length);
hdnCtrl.value = myChild;
alert(hdnCtrl);
}

while setting the array object for the hidden field, its not working for me is there there any other way

Thanks
