Can one execute two .click method calls consecutively in JavaScript?

Question

Can one execute two .click method calls consecutively in JavaScript?

My JavaScript code looks like this:

function AutoClickButtons() {
   document.getElementById('Button1').click();
   document.getElementById('Button2').click();
}

Oddly, only Button2 is being clicked when I run the function. But if I switch the order of the statements, then only Button1 (which is now called second) works.

Just to provide more context, the button clicks trigger ajax calls and partial page updates.

UPDATE: Using setTimeout does solve the issue, but it has a performance drawback. Upon further investigation, I discovered that the two buttons are ASP.NET buttons inside update panels. If I click them consecutively, everything functions properly. However, if I click one quickly followed by clicking the other before the first finishes, the second one succeeds while the first fails. This appears to be a problem specific to update panels and ASP.NET. Is there a way to modify something on that end to make the JavaScript code work seamlessly without relying on setTimeout?

Answer №1

I think this solution might do the trick. You can try using a setTimeout function to click the second button after the first one is clicked. It's not the cleanest approach, but it could work.

function handleClick() {
  document.getElementById('#firstButton').click();
  setTimeout(clickSecondButton, 300);
}

function clickSecondButton() {
  document.getElementById('#secondButton').click();
}

Have you considered utilizing IE's fireEvent() function?

function ClickButtons() {
  document.getElementById("Button1").fireEvent("onclick");
  document.getElementById("Button2").fireEvent("onclick");
}

Here's a working example (tested in IE6):

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <title>Click Test</title>
  </head>

  <body>
    <button id="Button1" onclick="alert('Button1 Clicked');">Click 1</button>
    <button id="Button2" onclick="alert('Button2 Clicked');">Click 2/button>
    <script type="text/javascript">
      document.getElementById("Button1").fireEvent("onclick");
      document.getElementById("Button2").fireEvent("onclick");
    </script>
  </body>
</html>

It should be noted that the use of click() is specific to IE, so this solution reflects that. Event handling varies across browsers, but with some wrappers, the differences can be abstracted away.

Both events should trigger successfully. Have you tried simplifying your code by removing the complex ajax requests and replacing them with a simple alert or console.log? Also, could you provide more details on how you are handling event listeners?
