Javascript variable in ASPX page in IF condition.

Question

It's been a while.

But on an ASPX page...if I have a variable that is defined as a global variable hoe can I use that in like the ASPX aspect with like an IF statement.

For example I have a "<script type="text/javascript"> in there I have a "var bitSet = "True"

Then later in the aspx code I have something like

a: (yes, this is VB.NET)

<div class="TestBit" id="TestBit">

<% If (BitSet) Then %>
<h3 class="BitTrue">True</h3>
<% Else %>
<h3 class="BitTrue">False</h3>
<% End If %>

</Div>

But how do I get the BitSet value from the Javascript in this condition?

Hi @Marc Davis ,

But how do I get the BitSet value from the Javascript in this condition?

According to your requirement, this cannot be implemented. I think you should learn and try to understand the Page Life-Cycle, so you will understand why this requirement cannot be implemented.

Because the embed code block is executed before the javascript code. The former (embedded code block) is executed during the page rendering phase, while the latter (javascript code) needs to be executed after the page cycle mentioned earlier, so if you are not pass the variable to server side using postbacks or requests (eg Ajax), you will never get this parameter.

Hope this can help.

Best regards,
