Question

I am trying to send an asp control (textbox) to a javascript function.

onblur="CalculateLossRatio(this.value,<%=txtLossRatioCurrentYear.ClientID%>)"

Is is the right way to do this.

Answer 1

In your situation you could do something like the following:

<asp:TextBox ID="TextBox1" onblur="CalculateLossRatio(this.value, 1)" runat="server" />
<asp:TextBox ID="TextBox2" runat="server" Text="7"/>

<script type="text/javascript">

function CalculateLossRatio(arg1, arg2)
{
    if (arg2 == 1)
    {
        var txt = document.getElementById('<%=TextBox2.ClientID%>');
    }
    else if(arg2 == 2)
    {
        // TODO - get other txt...
    }

    alert(arg1 - txt.value);
}

</script>
