Can't get value from getValue in JS and can't show value in showValue field.
Thanks in advance
ASPX PAGE CODE
<script>
var x = document.getElementById("<%=getValue.ClientID %>").innerHTML;
document.getElementById('showValue').innerHTML = x;
</script>
<asp:Label runat="server" ID="getValue" />
<asp:Label runat="server" ID="showValue" />
C# CODE
getValue.Text = "value from code";
You need to call javascript once all the controls are rendered, then only you can get the proper id of the <asp:label> control, so you need to write that javascript code under window.onload().
Also for showValue, you need to use ClientID.
window.onload= function(){
var x = document.getElementById("<%=getValue.ClientID%>").innerHTML;
document.getElementById('<%=showValue.ClientID %>').innerHTML = x;
};
