Hello,
I had a working ASP.Net (VB.Net) website which utilized a javascript routine during StartUp.
It would do a document.getElementsByTagName("input"); to find all of the Input objects and then selectively work on their style values as initialization processing.
It all worked fine.
var elemInputs = document.getElementsByTagName("input");
for(var i = 0; i < (elemInputs.length-1); i++)
{
var inputField = elemInputs[i].name;
if(inputField.indexOf('chkLot') == 0) {
// --- processing code here... ---
}
}
Previously worked fine.
Now I have added Ajax to the mix with an UpdatePanel.
That alone made things a 'challenge' because my VB.Net: ScriptManager.RegisterClientScriptBlock() was no longer working to launch the intended code.
But, after much web searching, I finally got the right VB.Net code to launch the intended startup javascript routine.
ScriptManager.RegisterClientScriptBlock(TryCast(sender, Control), Me.GetType(), Guid.NewGuid().ToString(), "startUpScript()", True)
Setting breakpoints in Firebug enable me to confirm that the intended code is being executed.
But now my document.getElementsByTagName("input"); is no longer 'seeing' the various Input objects and therefore does not act upon their style.
When I look at elemInputs within FireBug, I no longer see it containing the variety of Input objects that I need to find.
What is going on?
How can I resolve this so that the Startup javascript 'sees' the form objects?
