Keep in mind that the IDs generated by WebForms on the client side have a "rare" form, this is to keep all unique IDs, therefore:

var nombre1 = $('#<%= TextBox1.ClientID %>').val();

If you use both a

<input id="id_etiqueta"> o <textarea id="id_etiqueta">

You can capture the value with

var nombre1 = document.getElementById("id_etiqueta").value;

or assign the value

document.getElementById("id_etiqueta").value = "Valor Nuevo";
