How to enable bootstrap tooltip on disabled button

2019-01-10 10:20发布

问题:

I need to display a tooltip on disabled button and remove it on enabled button. Actually it works in reverse way.

What is the best way to invert this behaviour?

$('[rel=tooltip]').tooltip();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<hr>
<button class="btn" disabled rel="tooltip" data-title="Dieser Link führt zu Google">button disabled</button>
<button class="btn" rel="tooltip" data-title="Dieser Link führt zu Google">button not disabled</button>

Here is the demo: http://jsfiddle.net/BA4zM/68/

P.S.: I want to keep the attribute disabled.

Here is some working code: http://jsfiddle.net/mihaifm/W7XNU/200/

$('body').tooltip({
    selector: '[rel="tooltip"]'
});

$(".btn").click(function(e) {
    if (! $(this).hasClass("disabled"))
    {
        $(".disabled").removeClass("disabled").attr("rel", null);

        $(this).addClass("disabled").attr("rel", "tooltip");
    }
});

The idea is to add the tooltip to a parent element with the selector option, and then add/remove the rel attribute when enabling/disabling the button.



回答2:

You can wrap the disabled button and put the tooltip on the wrapper:

<div class="tooltip-wrapper" data-title="Dieser Link führt zu Google">
  <button class="btn btn-default" disabled>button disabled</button>
</div>

If the wrapper has display:inline then the tooltip doesn't seem to work. Using display:block and display:inline-block seem to work fine. It also appears to work fine with a floated wrapper.

UPDATE Here's an updated JSFiddle that works with the latest Bootstrap (3.3.6). Thanks to @JohnLehmann for suggesting pointer-events: none; for the disabled button.

回答3:

This can be done via CSS. The "pointer-events" property is what's preventing the tooltip from appearing. You can get disabled buttons to display tooltip by overriding the "pointer-events" property set by bootstrap.

.btn.disabled {
    pointer-events: auto;
}

If you're desperate (like i was) for tooltips on checkboxes, textboxes and the like, then here is my hackey workaround:

$('input:disabled, button:disabled').after(function (e) {
    d = $("<div>");
    i = $(this);
    d.css({
        height: i.outerHeight(),
        width: i.outerWidth(),
        position: "absolute",
    })
    d.css(i.offset());
    d.attr("title", i.attr("title"));
    d.tooltip();
    return d;
});

Working examples: http://jsfiddle.net/WB6bM/11/

For what its worth, I believe tooltips on disabled form elements is very important to the UX. If you're preventing somebody from doing something, you should tell them why.



回答5:

These workarounds are ugly. I've debugged the problem is that bootstrap automatically set CSS property pointer-events: none on disabled elements.

This magic property causes that JS is not able to handle any event on elements that matches CSS selector.

If you overwrite this property to default one, everything works like a charm, including tooltips!

.disabled {
  pointer-events: all !important;
}

However you shouldn't use so general selector, because you will probably have to manually stop JavaScript event propagation way you know (e.preventDefault()).



回答6:

You can't get the tool-tip to show on a disabled button. This is because disabled elements don't trigger any events, including the tool-tip. Your best bet would be to fake the button being disabled (so it looks and acts like its disabled), so you can then trigger the tool-tip.

Eg. Javascript:

$('[rel=tooltip].disabled').tooltip();

$('[rel=tooltip].disabled').bind('click', function(){
     return false;
});

Instead of just $('[rel=tooltip]').tooltip();​

HTML:

<hr>
<button class="btn disabled" rel="tooltip" data-title="Dieser Link führt zu Google">button disabled</button>

<button class="btn" rel="tooltip" data-title="Dieser Link führt zu Google">button not disabled</button>

回答7:

In my case, none of the above solutions worked. I found that it's easier to overlap the disabled button using an absolute element as:

<div rel="tooltip" title="I workz" class="wrap">
  <div class="overlap"></div>
  <button>I workz</button>
</div>

<div rel="tooltip" title="Boo!!" class="wrap poptooltip">
  <div class="overlap"></div>
  <button disabled>I workz disabled</button>
</div>

.wrap {
  display: inline-block;
  position: relative;
}

.overlap {
  display: none
}

.poptooltip .overlap {
  display: block;
  position: absolute;
  height: 100%;
  width: 100%;
  z-index: 1000;
}

回答8:

Try this example:

Tooltips must be initialized with jQuery: select the specified element and call the tooltip() method in JavaScript:

$(document).ready(function () {
    $('[data-toggle="tooltip"]').tooltip();
});

Add CSS:

.tool-tip {
  display: inline-block;
}

.tool-tip [disabled] {
  pointer-events: none;
}

And your html:

<span class="tool-tip" data-toggle="tooltip" data-placement="bottom" title="I am Tooltip">
    <button disabled="disabled">I am disabled</button>
</span>


回答9:

This is what myself and tekromancr came up with.

Example element:

<a href="http://www.google.com" id="btn" type="button" class="btn btn-disabled" data-placement="top" data-toggle="tooltip" data-title="I'm a tooltip">Press Me</a>

note: the tooltip attributes can be added to a separate div, in which the id of that div is to be used when calling .tooltip('destroy'); or .tooltip();

this enables the tooltip, put it in any javascript that is included in the html file. this line might not be necessary to add, however. (if the tooltip shows w/o this line then don't bother including it)

$("#element_id").tooltip();

destroys tooltip, see below for usage.

$("#element_id").tooltip('destroy');

prevents the button from being clickable. because the disabled attribute is not being used, this is necessary, otherwise the button would still be clickable even though it "looks" as if it is disabled.

$("#element_id").click(
  function(evt){
    if ($(this).hasClass("btn-disabled")) {
      evt.preventDefault();
      return false;
    }
  });

Using bootstrap, the classes btn and btn-disabled are available to you. Override these in your own .css file. you can add any colors or whatever you want the button to look like when disabled. Make sure you keep the cursor: default; you can also change what .btn.btn-success looks like.

.btn.btn-disabled{
    cursor: default;
}

add the code below to whatever javascript is controlling the button becoming enabled.

$("#element_id").removeClass('btn-disabled');
$("#element_id").addClass('btn-success');
$('#element_id).tooltip('destroy');

tooltip should now only show when the button is disabled.

if you are using angularjs i also have a solution for that, if desired.



回答10:

You can simply override Bootstrap's "pointer-events" style for disabled buttons via CSS e.g.

.btn[disabled] {
 pointer-events: all !important;
}

Better still be explicit and disable specific buttons e.g.

#buttonId[disabled] {
 pointer-events: all !important;
}

Working code for Bootstrap 3.3.6

Javascript:

$('body').tooltip({
  selector: '[data-toggle="tooltip"]'
});

$(".btn").click(function(e) {
 if ($(this).hasClass("disabled")){
   e.preventDefault();
 }
});

CSS:

a.btn.disabled, fieldset[disabled] a.btn {
  pointer-events: auto;
}


回答12:

You can imitate the effect using CSS3.

Simply take the disabled state off the button and the tooltip doesn't appear anymore.. this is great for validation as the code requires less logic.

I wrote this pen to illustrate.

CSS3 Disabled Tooltips

[disabled] {
  &[disabled-tooltip] {
    cursor:not-allowed;
    position: relative;
    &:hover {
      &:before {
        content:'';
        border:5px solid transparent;
        border-top:5px solid black;
        position: absolute;
        left: 50%;
        transform: translate(-50%, calc(-100% + -5px));
      }
      &:after {
        content: attr(disabled-tooltip);
        position: absolute;
        left: 50%;
        transform: translate(-50%, calc(-100% + -15px));
        width:280px;
        background-color:black;
        color:white;
        border-radius:5px;
        padding:8px 12px;
        white-space:normal;
        line-height:1;
      }
    }
  }
}

<button type="button" class="btn btn-primary" disabled-tooltip="I am a disabled tooltip using CSS3.. You can not click this button." disabled>Primary Button</button>


回答13:

pointer-events: auto; does not work on an <input type="text" />.

I took a different approach. I do not disable the input field, but make it act as disabled via css and javascript.

Because the input field is not disabled, the tooltip is displayed properly. It was in my case way simpler than adding a wrapper in case the input field was disabled.

$(document).ready(function () {
  $('.disabled[data-toggle="tooltip"]').tooltip();
  $('.disabled').mousedown(function(event){
    event.stopImmediatePropagation();
    return false;
  });
});
input[type=text].disabled{
  cursor: default;
  margin-top: 40px;
}

    disabled
    data-hint="Enabled">
  <div class="sp-btn-overlap" data-hint="Disabled"></div>

CSS

button { position:relative; }

.sp-btn-overlap {
