Tooltips + Highlight Animation With Clipboard.js Click

问题

I've successfully installed clipboard.js and have gotten snippets of text to copy to the clipboard upon click. I'm going to be nesting these snippets of text (or the "btn"s they're within) in the cells of a table.

My challenge:

I need the snippets of text to give me a Tooltip "Copied!" message so that people are aware they are clickable. A great example of this is on the clipboard.js documentation page -- click on any of the buttons that cut or copy to see the tooltip message.

From clipboard.js' documentation:

Although copy/cut operations with execCommand aren't supported on Safari yet (including mobile), it gracefully degrades because Selection is supported.

That means you can show a tooltip saying Copied! when success event is called and Press Ctrl+C to copy when error event is called because the text is already selected.

I'm not particularly adept at JS (it took me a few hours to get this far). So I'm at a dead end... was able to install everything on WP, enqueue the script, and add the text/ functionality:

 <!-- 1. Define some markup -->
    <div id="btn" data-clipboard-text="1">
        <span>text to click</span>
    </div>

    <!-- 2. Include library -->
    <script src="/path/to/dist/clipboard.min.js"></script>

    <!-- 3. Instantiate clipboard by passing a HTML element -->
    <script>
    var btn = document.getElementById('btn');
    var clipboard = new Clipboard(btn);

    clipboard.on('success', function(e) {
    console.log(e);
    console.info('Action:', e.action);
    console.info('Text:', e.text);
    console.info('Trigger:', e.trigger);
    });

    clipboard.on('error', function(e) {
        console.log(e);
        console.error('Action:', e.action);
        console.error('Trigger:', e.trigger);
    });
    </script>

What should I add? Thanks!

Seems like all you want to do is integrating Clipboard.js with a Tooltip solution.

So here's how you can accomplish that using Bootstrap's Tooltip.

// Tooltip

$('button').tooltip({
  trigger: 'click',
  placement: 'bottom'
});

function setTooltip(btn, message) {
  $(btn).tooltip('hide')
    .attr('data-original-title', message)
    .tooltip('show');
}

function hideTooltip(btn) {
  setTimeout(function() {
    $(btn).tooltip('hide');
  }, 1000);
}

// Clipboard

var clipboard = new Clipboard('button');

clipboard.on('success', function(e) {
  setTooltip(e.trigger, 'Copied!');
  hideTooltip(e.trigger);
});

clipboard.on('error', function(e) {
  setTooltip(e.trigger, 'Failed!');
  hideTooltip(e.trigger);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.5.10/clipboard.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<link href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<button class="btn btn-primary" data-clipboard-text="It worked!">Click me</button>
<button class="btn btn-primary" data-clipboard-text="It worked again!">Click me</button>

I've come up with a slight improvement to Zeno's code, which wraps it in a jQuery function, and supports copying from an arbitrary element:

if (typeof $.uf === 'undefined') {
    $.uf = {};
}

$.uf.copy = function (button) {
    var _this = this;

    var clipboard = new ClipboardJS(button, {
        text: function(trigger) {
            var el = $(trigger).closest('.js-copy-container').find('.js-copy-target');
            if (el.is(':input')) {
                return el.val();
            } else {
                return el.html();
            }
        }
    });

    clipboard.on('success', function(e) {
        setTooltip(e.trigger, 'Copied!');
        hideTooltip(e.trigger);
    });

    clipboard.on('error', function(e) {
        setTooltip(e.trigger, 'Failed!');
        hideTooltip(e.trigger);
    });

    function setTooltip(btn, message) {
        $(btn)
        .attr('data-original-title', message)
        .tooltip('show');
    }
    
    function hideTooltip(btn) {
        setTimeout(function() {
            $(btn).tooltip('hide')
            .attr('data-original-title', "");
        }, 1000);
    }

    // Tooltip
    $(button).tooltip({
        trigger: 'click'
    });
};

// Link all copy buttons
$.uf.copy('.js-copy-trigger');

<script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.5.10/clipboard.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<form>
 <div class="form-group">
  <label>Email</label>
  <div class="input-group js-copy-container">
    <input type="text" class="form-control js-copy-target" name="email" autocomplete="off" value="example@example.com" placeholder="Email goes here" disabled>
    <span class="input-group-btn">
      <button class="btn btn-default js-copy-trigger" type="button">Copy</button>
    </span>
  </div>
 </div>
</form>

You'll notice that we have our button with a class of js-copy-trigger, and the text/control to be copied with the js-copy-target class. Both of these are wrapped in a common js-copy-container class.

This is much better than using id targets, because you often need to generate multiple copy buttons (for example, in a table), and ids must be unique on a page.
