JAVASCRIPT NOT EXECUTING THE ELSE PART

Abraham Olatubosun

My Code master,

Good day to you all, i have a JavaScript that test ASP.NET TextBox if it not empty,

if the TextBox is not empty it replace the value entered to it self else it should add the value entered to the existing value.

below is my code

var T797 = parseInt(document.getElementById('<%=TextBox797.ClientID%>').value);
if (T797 !="" || T797 >= 0)
{
document.getElementById('<%=TextBox797.ClientID%>').value = parseInt(document.getElementById('<%=TextBox651.ClientID%>').value);
}else{
document.getElementById('<%=TextBox797.ClientID%>').value = parseInt(document.getElementById('<%=TextBox797.ClientID%>').value) + parseInt(document.getElementById('<%=TextBox651.ClientID%>').value);
}

please correct me where i am wrong

thank you

Try to put the alert() message inside both if and else,
also try to put the value of T797 in alert so you know what is happening.

thank you my code masters,

Bryian Tan the TextBox797 contains number if the application is in Edit Mode if not, it will be empty. so, the thing is if i type in a number in TextBox651.Text which have the method call onKeyUp="sumUpHTC3()"
"TextBox651" runat="server" Width="52px" onKeyUp="sumUpHTC3()">
the function sumUpHTC3() is where validation of T797 takes place, if it contain number it should add the content of TextBox651 to what ever TextBox797 have. Simple but the JavaScript is not doing the ELSE part

replace this line:
if (T797 !="" || T797 >= 0)
with this line:
if (T797 == 0)

What did you entered into textbox TextBox797?

The operator should be && instead of ||
if (T797 != "" && T797 >= 0) {
