CallBack Manager - Masterpage

[Guest]

Hello

i make my first steps with the Callback Manager
for example

function Script_CalculateValues(result,context)
{
alert("test : \n" + result);
//document.forms[0].elements["txtHG"].value = "2test";
//document.all.txtHG.Value = "2test";
//document.getElementById("txtHG").value = "fjkds";
//document.all.ContentPlaceHolder1.Label2.Text = "test";
}

When i use a Masterpage, i cannot access the textbox.
the contentplaceholder includes the textbox
all variants in the upper example were unsuccessful

ANY IDEA

Solution

document.getElementByID('ctl00_ContentPlaceHolder1_txtHG').value

You shouldn't hard-code this ID into your js code. Instead dynamically emit
the js with the Control.ClientID property -- this is the ID that the control
will have in the browser.

Solution

document.getElementByID('ctl00_ContentPlaceHolder1_txtHG').value
