Access Repeater values using JavaScript

Question

i searched a lot on NET, to get the solution, but i could not find

Can anyone tell me how to access the label and textbox values of repeater control inside using the javascript ?

This is my code

 <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"> <ItemTemplate> <table id="t1" width="200px:" style="background-color: skyblue" runat="server"> <tr> <td> <asp:TextBox ID="TextBox3" Text='<%#DataBinder.Eval(Container.DataItem, "empid")%>' runat="server" /> <asp:CheckBox ID="CheckBox1" runat="server" /> <asp:Label ID="Label1" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "empid")%>'></asp:Label> <asp:Label ID="lblname" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "ename")%>'></asp:Label> <br /> <br /> </td> </tr> </table> </ItemTemplate> </asp:Repeater>

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); }

Please provide the relevant HTML you are asking about.

<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.

but on alert i got [object Object]

Yes, that gives you a reference to the object. You can get the value with $('.myLabel').eq(0).text() or $('.myLabel').eq(0).html()

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.

I tried your code but not getting it , i put the <table> of repeater inside the <div id="mydiv"><table>.. and write the code this way 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); }
