Use this JS function in ASP.net:

function habilitado(){
    var b = document.getElementById('<%= Label4.ClientID %>').value = "Habilitado";
}

I call it that in codebehind. The value of the label should be changed, but it doesn’t happen. Someone can help?

Note: I’ve tried using $(document).ready(function() at first, and yet it doesn’t work.

ClientScript.RegisterClientScriptBlock(this.GetType(), "teste", "<script language=\"javascript\">habilitado();</script>");
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "teste", "<script type='text/javascript'>habilitado();</script>", true);

  • When you load the page in the browser, does the generated Javascript look like this? Have you checked if the first string ('<%= Label4.ClientID %>') replaced by label ID?

The option value is not applicable for Abels. Try to exchange for innerHTML. Thus:

document.getElementById('<%= Label4.ClientID %>').innerHTML = "Habilitado";

With jQuery can be done so:

$('#<%= Label4.ClientID %>').html("Conteúdo novo...");
