Now i want to access the label, textbox of repeater using javascript

@Diodeus

I tried your code

function submitAll() {
        var thisLabel = $('.myLabel').eq(0);
        alert(thisLabel);
    }

But i got the result in alert as

[object Object]

and @deostroll

I tried your code this way

But not getting anything

    function GetData() {
        var arrTables = document.getElementById('myDiv').getElementsByTagName('table');
        var tbl = arrTables[0];
        var td = tbl.childNodes[0].childNodes[0].childNodes[0];
        var txt = td.childNodes[0];
        alert(txt.value);        
    }

Answer 1

<asp:Label ID="Label1" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "empid")%>'></asp:Label>

IDs must be unique, so you can't apply the same ID to all of the labels in your repeater. Use CSS class names instead.

<asp:Label CssClass="myLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "empid")%>'></asp:Label>

Since jQuery comes with .NET you can use it instead of plain JavaScript to access these elements more easily.

var thisLabel = $('.myLabel').eq(0) where 0 is the index of the element since there can be many.

Answer 2

Wrap the repeater in a div with some id, say myDiv.

<div id="myDiv">
<!-- your repeater code -->
<asp:Repeater ID="Repeater1" runat="server"...>
<ItemTemplate>
<table>...</table>
</ItemTemplate>
</asp:Repeater>
</div>

Do a

var arrTables = document.getElementById('myDiv').getElementsByTagName('table');

Now arrTables is just array of all table elements inside the div. Find the ordinal of the desired table: For e.g. sake I am taking first table.

var tbl = arrTables[0];

Find the corresponding td of the table element:

var td = tbl.childNodes[0].childNodes[0].childNodes[0];

The above may vary based on how your browser loads the DOM and stuff. Hence I say you debug and find out for your self.

Once you get the td reference:

var txt = td.childNodes[0];

This will give the textbox. txt.nextSibling will give the label...and so on.
