i have a tab conatiner with 5 tabs
i need to get the active tab index
so i have a javascript to get teh active tabindex but i get error
below is the runtime code viewd in browser
Sys.Application.add_init(function() {
$create(AjaxControlToolkit.TabContainer, {“activeTabIndex”:0,“autoPostBackId”:“ctl00$ContentMain$Tabs”,“clientStateField”:$get(“ctl00_ContentMain_Tabs_ClientState”)}, {“activeTabChanged”:clientActiveTabChanged}, null, $get(“ctl00_ContentMain_Tabs”));
});
function clientActiveTabChanged(sender, args)
{
document.getElementById(‘<%=Htabindex.ClientID%>’).value=sender.get_activeTabIndex();
}
The code you posted isn’t enough for anyone to debug it, since it’s clearly relying on ColdFusion? or something on the back making HTML, and then obviously some library or hand-made tools…
But you may want to look here
“clientStateField”:$get(“ctl00_ContentMain_Tabs_ClientState”
Here you’r getting a value of the state of your tabs, so you might want to check that clientStateField isn’t null, but actually gets something. I assume the program has to get the states before picking out the one who’s active first. “activeTabChanged” is being assigned the function below… does that function actually get useful stuff for the sender and args parameters?
If this code were plopped in my lap, that would be where I would start, not knowing anything else. You are using a debugger in your browser?
