[RESOLVED] Button click and hold

[daarsk]

I have an asp Button1 increasing Label1 by value 1 on each click (VB), how would I get the label to increase by holding the button instead of click click click.

Thanks James

So, the application is ASP.NET Web Forms?

[daarsk]

Yes it is. ASPX with VB code behind

You can't achieve that using .vb/server side code, only in javascript/jquery.
See link: Javascript-easily-do-a-continuous-action-on-mouse-hold

Theoretically it may be done with an updatepanel and a timer but it would still need Javascript for the mouse down.
That is why Javascript rulez and server side (MVC) sucks!!! :P

Thanks for moving thread (sorry)

I'm afraid my knowledge of Java sits somewhere between 0 and null. I guess I put the code between <script type="text/javascript"> tags on my aspx page? Then how do tie that code to a button? In fact I have 2 buttons; 1 to go up and 1 to go down.

It may take a bit for me to get my head around this, sorry if I'm too much trouble. Help is obviously highly appreciated.

Thanks James

I also found this, but I can't get it to work.

You really are determined to make a fool of yourself aren't you? For one thing, this is a Web Forms app, not MVC. Secondly, JavaScript is just a language and can be executed server-side too, e.g. using Node.js. Thirdly, without some sort of server-side technology, be it Web Forms, ASP.NET MVC, Ruby on Rails or whatever, there's nothing to send JavaScript code to the client to be executed there. Your comment is like saying cars rule and engines suck. It's just plain stupid.

I do love a good argument... but... I still need a button click and hold function please.

Thanks

Did you read post #5?

Have you tried my suggestion? it works and i've tested it. Reference jQuery either downloading the script from the source site or via Nuget.

Basically, this is a webforms app

based from post #3.

Did you read post #5?

[daarsk]

I did read post #5, maybe I should have quoted it when posting #7. Sorry.

I'm not here to upset anyone, but clearly my level of expertise is very very low. So I can understand how this could be frustrating. Sorry again. Also, I'm not very good at this, my posts always seem sarcastic, I can assure you, they are not.

Anyway, I can see that code on the link you gave (post #5). Unfortunately for me, I know nothing about javascript. Let me quote the code first.

var intervalHandler;
$('#'+obj_id).mousedown(function() {
  intervalHandler = setInterval(function() { doTheWork(); }, 100);
  return false;
})
$('#'+obj_id).mouseup(function() {
  clearInterval(intervalHandler);
});

function doWork() {
  //I am working here
}

Now, firstly, "doTheWork" "DoWork", is that an error?
Where do I put this code? I was thinking on my aspx page between <script type="text/javascript"> tags. Would that be ok?
I assume "//I am working here" would be where I put the code to increase Label1 +1, but again, I don't know how to code java, maybe I should learn, that might be a good thing...
If my button is <asp:Button id="Button1" />, how do I get the button to run the javascript for <asp:Label id="Label1" />?

I do appreciate all your help and patience.

Thanks,
James

This is what I have put together so far. But clicking the buttons does nothing...

<asp:Label ID="Label1" runat="server" Text="0" />
<input type="button" ID="ButtonUp" Value="Up" />
<input type="button" ID="ButtonDown" Value="Down" />

<script type="text/javascript">
   Var intervalHandler;
   $('ButtonUp').mousedown(function () {
      intervalHandler = setInterval(function () { FactUp(); }, 100);
      return false;
   })
   $('ButtonUp').mouseup(function () {
      clearInterval(intervalHandler);
   });

   $('ButtonDown').mousedown(function () {
      intervalHandler = setInterval(function () { FactDown(); }, 100);
      return false;
   })
   $('ButtonDown').mouseup(function () {
      clearInterval(intervalHandler);
   });

   function FactUp() {
      var obj = document.getElementById('Label1');
      var num = parseFloat(obj.value);
      if (isNaN(num)) {
         return;
      }
      num = new Integer(num.intValue() + 1);
      obj.value = num;
   }

   function FactDown() {
      var obj = document.getElementById('Label1');
      var num = parseFloat(obj.value)
      if (isNaN(num)) {
         return;
      }
      num = new Integer(num.intValue() - 1);
      obj.value = num;
   }
</script>

I have submitted a solution in our very own asp.net codebank: http://www.vbforums.com/showthread.p...use-down-click. Just follow the instructions and the code.

It's JavaScript not Java. Java is to JavaScript what a car is to a carpet.

@KGC
Thanks, I have now got an idea on what it all means. I can see where I went wrong and my adventure on the learning curve continues

@Joacim
Thanks, I understand now. Just goes to show how little someone can know, I now feel like carpet, lol
