<h2>Panel Demo</h2>
<div class="border"> <textarea id="code" name="code"></textarea></div>
<p> The <a href="../doc/manual.html#addon_panel"><code>panel</code></a> addon allows you to display panels above or below an editor. <br> Click the links below to add panels at the given position:</p>
<div id="demo"><p> <a class="add-panel" onclick="addPanel('top')">top</a> <a class="add-panel" onclick="addPanel('after-top')">after-top</a> <a class="add-panel" onclick="addPanel('before-bottom')">before-bottom</a> <a class="add-panel" onclick="addPanel('bottom')">bottom</a></p><p> You can also replace an existing panel:</p><form onsubmit="return replacePanel(this);" name="replace_panel"> <input type="submit" value="Replace panel n°" /> <input type="number" name="panel_id" min="1" value="1" /></form>
<script>var textarea = document.getElementById("code");var demo = document.getElementById("demo");var numPanels = 0;var panels = {};var editor;
textarea.value = demo.innerHTML.trim();editor = CodeMirror.fromTextArea(textarea, { lineNumbers: true, mode: "htmlmixed"});
function makePanel(where) { var node = document.createElement("div"); var id = ++numPanels; var widget, close, label;
node.id = "panel-" + id; node.className = "panel " + where; close = node.appendChild(document.createElement("a")); close.setAttribute("title", "Remove me!"); close.setAttribute("class", "remove-panel"); close.textContent = "✖"; CodeMirror.on(close, "mousedown", function(e) { e.preventDefault() panels[node.id].clear(); }); label = node.appendChild(document.createElement("span")); label.textContent = "I'm panel n°" + id; return node;}function addPanel(where) { var node = makePanel(where); panels[node.id] = editor.addPanel(node, {position: where, stable: true});}
