Add tooltip to a disabled bootstrap button

Question

I've tried solutions found on other similar threads, but can't get them working.

I've got a bootstrap button that, when in a disabled state, should have a tooltip letting the user know why it's disabled.

I understand that a button in disabled state has a CSS that prevents mouseover events from reaching the button element, and that there are workarounds for this.

What am I doing wrong in the below code?

 // Grab button from DOM
 let resultsBtn = document.getElementById("get-results-btn");
 
 // if conditional is met, disable button
    $(resultsBtn).prop("disabled", true);
    
    // then, add tooltip 
       $(resultsBtn).attr("data-toggle", "tooltip");
       $(resultsBtn).attr("title", "you may only submit this form once");

       // add css rules to make tooltip work on disabled button
          $(resultsBtn).css("pointer-events", "none"); 

/* ====================================== */
/* Button styling */
/* ====================================== */

#get-results-btn {
  // insert styling rules for color, size, etc. here, plus the following rules:
  cursor: pointer;
  user-select: none;
  -webkit-user-select: none;
  touch-action: manipulation;
  pointer-events: none; ////// Added this based on [S/O thread][1]
}

#get-results-btn  .btn[disabled] //// I pulled this line from [S/O thread][1], but I don't think the class applies to my code?

<button id="get-results-btn" class="btn standard-btn-style">
  Get Results
</button>

Try this code:

 // Grab button from DOM
 let resultsBtn = "#wrapper";
 
 //// if conditional is met, disable button
 $("#get-results-btn").prop("disabled", true);
    
    // then, add tooltip 
       $(resultsBtn).attr("data-bs-toggle", "tooltip");
       $(resultsBtn).attr("title", "you may only submit this form once");

#get-results-btn {
  display: inline-block;
}

#get-results-btn .btn[disabled] {
    pointer-events: none;
    
}

<div id="wrapper">

<button id="get-results-btn" class="btn standard-btn-style">
  Get Results
</button>

</div>

Changes I made to your code:

• Added a wrapper div to the button, so the wrapper can show the tooltip

• You was added pointer-events: none to the wrong class. Corrected it.

• In javascript code, it should be data-bs-toggle not data-toggle.

As per the documentation:

Elements with the disabled attribute aren’t interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you’ll want to trigger the tooltip from a wrapper <div> or <span>, ideally made keyboard-focusable using tabindex="0", and override the pointer-events on the disabled element.

Example quoting from the documentation itself:

<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
