You can try this:-

 document.getElementById("<%=Label1.ClientID%>").value = "new text value";

or you can try

 var elMyElement = document.getElementByID('<%= Label1.ClientID %>');

  elMyElement.innerHTML = "your text here";

Label1 is the server side ID of the Label control. Use the ClientID to access it from the javascript. Try this:

document.getElementById("<%=Label1.ClientID%>").innerHTML= "new text value";

Hope this will help.

The asp.net label is rendered as a span so you need to set its innerHTML property not the value property, another option is to use JQuery and use the .text() method

ASP.NET changes "Label1" to something like MasterPageContent_Label1 when rendered to the client. Also ASP.NET Label controls are renderd to the client as <span> elements so you need to use innerHTML as opposed to value to set the content.

document.getElementById('<%= Label1.ClientID %>').innerHTML = "new text value";

You need to get the ClientID of the control in order to manipulate it in JavaScript.

The ClientID is the Id that gets rendered in the browser.

document.getElementById("<%=Label1.ClientID%>").value = "new text value";
