JAVASCRIPT NOT DISPLAYING THE RIGHT VALUE

Abraham Olatubosun

Dear Code Masters,

Many thanks for all your support so far, i asked some question regarding javascript some days ago, though it wasn't answered but it gave me qlues that finally solve the issue.
but now, am faced with another kind of javascript problem, i would have solve this using C# ASP.NET code behind but i want performance in the user interface that is why i am using javascript.

looking at the javascript below kindly advice me why TextBox87 is displaying the value 6.

document.getElementById('<%=TextBox87.ClientID%>').value = 4;
document.getElementById('<%=TextBox103.ClientID%>').value = 1;
document.getElementById('<%=TextBox104.ClientID%>').value = 1;
document.getElementById('<%=TextBox87.ClientID%>').value = parseInt(document.getElementById('<%=TextBox87.ClientID%>').value) + parseInt(document.getElementById('<%=TextBox103.ClientID%>').value) + parseInt(document.getElementById('<%=TextBox104.ClientID%>').value);
many thanks

am not sure but NAN error getting when trying to
will be undefined and undefined + 1 == NaN
Your textbox under the panel or under the form. update the every text box ClientIDMode="Static".
when ClientIDMode is static no changed the client id.

Many thanks to Nitin and all those that response to my question, i don't think if any of you have a child who is new to javascript and asked you such a question, will response with an awkward answer.
As you correctly know Nitin am expecting 6 in Textbox87 but all it display is NaN.

Thank you all

Hi,
Always TextBox87 will return 6 (according to your javascipt code) because
TextBox87 is storing the values of TextBox87 , TextBox103 and TextBox104 means(4+1+1).

what do you want ? and whats your expected answer ?

Because in the schools we were taught that 4 + 1 + 1 = 6.

What answer are you expecting? and most importantly why?
