Add a <code>data-label</code> attribute to the <code>pre</code> element, and the Toolbar plugin will read the value of that attribute and append a label to the code snippet.</p> <pre data-label="Hello World!"><code class="language-markup"><pre data-src="plugins/toolbar/prism-toolbar.js" data-label="Hello World!"></pre></code></pre> <p>If you want to provide arbitrary HTML to the label, create a <code>template</code> element with the HTML you want in the label, and provide the <code>template</code> element's <code>id</code> to <code>data-label</code>. The Toolbar plugin will use the template's content for the button. You can also use to declare your event handlers inline:</p> <pre data-label="my-label-button"><code class="language-markup"><pre data-src="plugins/toolbar/prism-toolbar.js" data-label="my-label-button"></pre></code></pre> <pre><code><template id="my-label-button"><button onclick="console.log('This is an inline-handler');">My button</button></template></code></pre> <h2>Registering buttons</h2> <p>For more flexibility, the Toolbar exposes a JavaScript function that can be used to register new buttons or labels to the Toolbar, <code>Prism.plugins.toolbar.registerButton</code>.</p> <p>The function accepts a key for the button and an object with a <code>text</code> property string and an optional <code>onClick</code> function or a <code>url</code> string. The <code>onClick</code> function will be called when the button is clicked, while the <code>url</code> property will be set to the anchor tag's <code>href</code>.</p> <pre><code class="language-javascript">Prism.plugins.toolbar.registerButton('hello-world', { text: 'Hello World!', // required onClick: function (env) { // optional alert('This code snippet is written in ' + env.language + '.'); } });</code></pre> <p>See how the above code registers the <code>Hello World!</code> button? You can use this in your plugins to register your own buttons with the toolbar.</p> <p>If you need more control, you can provide a function to <code>registerButton</code> that returns either a <code>span</code>, <code>a</code>, or <code>button</code> element.</p> <pre><code class="language-javascript">Prism.plugins.toolbar.registerButton('select-code', function(env) { var button = document.createElement('button'); button.innerHTML = 'Select Code'; button.addEventListener('click', function () { // Source: http://stackoverflow.com/a/11128179/2757940 if (document.body.createTextRange) { // ms var range = document.body.createTextRange(); range.moveToElementText(env.element); range.select(); } else if (window.getSelection) { // moz, opera, webkit var selection = window.getSelection(); var range = document.createRange(); range.selectNodeContents(env.element); selection.removeAllRanges(); selection.addRange(range); } }); return button; });</code></pre> <p>The above function creates the Select Code button you see, and when you click it, the code gets highlighted.</p> <h2>Ordering buttons</h2> <p>By default, the buttons will be added to the code snippet in the order they were registered. If more control over the order is needed, the <code>data-toolbar-order</code> attribute can be used. Given a comma-separated list of button names, it will ensure that these buttons will be displayed in the given order. <br> Buttons not listed will not be displayed. This means that buttons can be disabled using this technique.</p> <p>Example: The "Hello World!" button will appear before the "Select Code" button and the custom label button will not be displayed.</p> <pre data-toolbar-order="hello-world,select-code" data-label="Hello World!"><code><pre data-toolbar-order="hello-world,select-code" data-label="Hello World!"><code></code></pre></code></pre> <p>The <code>data-toolbar-order</code> attribute is inherited, so you can define the button order for the whole document by adding the attribute to the <code>body</code> of the page.</p> <pre><code><body data-toolbar-order="select-code,hello-world,label"></code></pre> </section> <footer data-src="assets/templates/footer.html" data-type="text/html"></footer> <template id="my-label-button"><button onclick="console.log('This is an inline-handler');">My button</button></template> <script src="prism.js"></script> <script src="plugins/toolbar/prism-toolbar.js"></script> <script src="assets/vendor/utopia.js"></script> <script src="components.js"></script> <script> Prism.plugins.toolbar.registerButton('hello-world', { text: 'Hello World!', // required onClick: function (env) { // optional alert('This code snippet is written in ' + env.language + '.'); } }); </script> <script> Prism.plugins.toolbar.registerButton('select-code', function(env) { var button = document.createElement('button'); button.innerHTML = 'Select Code'; button.addEventListener('click', function () { // Source: http://stackoverflow.com/a/11128179/2757940 if (document.body.createTextRange) { // ms var range = document.body.createTextRange(); range.moveToElementText(env.element); range.select(); } else if (window.getSelection) { // moz, opera, webkit var selection = window.getSelection(); var range = document.createRange(); range.selectNodeContents(env.element); selection.removeAllRanges(); selection.addRange(range); } }); return button; }); </script> <script src="assets/code.js"></script> </body> </html>
