Trying to save the disabled property value of a hidden field in order to track the disabled state of a button between postbacks, using the following JavaScript
function TrackState(buttonID)
{
var trackingField = document.getElementById("_tracking" + buttonID);
return false; // prevent default action
}
In the HTML
<input type="hidden" name="_trackingButton1" value="true" />
However, every time trackingField appears to be null. What could be going wrong here?
To ensure proper functionality, make sure to set the id attribute of your element, not just the name. Here's how it should look:
<input type="hidden" id="_trackingButton1" name="_trackingButton1" value="true" />
I trust this information will be beneficial for you.
When you're defining your function
function CheckButton(buttonID) { }
do you know the exact value of buttonID? I'm assuming it's "Button1". And based on the function's usage of getElementById, the corresponding input should have an id property with that same value.
When using the getElementById() method, it targets elements with specific id values:
<div id="uniqueIdentifier" class="exampleClass" data-value="123">
