我在两个radtabs中有两个嵌套的网格视图，对于这两个嵌套视图，我有一个简单的JavaScript用于展开和折叠。
<script type="text/javascript">
function collapseExpand(obj) {
var gvObject = document.getElementById(obj);
var imageID = document.getElementById('image' + obj);
if (gvObject.style.display == "none") {
gvObject.style.display = "inline";
imageID.src = "~/ims/Images/bullet_toggle_minus.jpg";
}
else {
gvObject.style.display = "none";
imageID.src = "~/ims/Images/bullet_toggle_plus.jpg";
}
}
Java Script适用于第一个选项卡的第一个RadGrid。但是，它无法使用第二个选项卡。我认为控件无法转移到第二个网格。我认为我的问题类似于
我应用了那里列出的所有方法但仍无效。
<script type="text/javascript">
function load() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(collapseExpand);
}
function collapseExpand(obj) {
var gvObject = document.getElementById(obj);
var imageID = document.getElementById('image' + obj);
if (gvObject.style.display == "none") {
gvObject.style.display = "inline";
imageID.src = "~/ims/Images/bullet_toggle_minus.jpg";
}
else {
gvObject.style.display = "none";
imageID.src = "~/ims/Images/bullet_toggle_plus.jpg";
}
}
有人可以告诉我要编写哪些代码来传输或将javascript的控制权传递给第二个标签？
另外，我使用Radtabs和RadPageView在两个选项卡中显示两个网格。
我在radtab内部调用Collapse Expand

请尝试使用以下代码段。
JS
<script type="text/javascript">
function collapseExpand(obj, Id) {
var gvObject = document.getElementById('div_' + Id + '_' + obj);
var imageID = document.getElementById('imageSubId_' + Id + '_' + obj);
if (gvObject.style.display == "none") {
gvObject.style.display = "inline";
imageID.src = "http://www.fimfiction-static.net/images/icons/collapse.png";
}
else {
gvObject.style.display = "none";
imageID.src = "http://jlpa.trinitylaban.ac.uk/WebCat_Images/English/Other/MiscD/admin-icon-expand.png";
