First, look at the renderings
usage method
Typecho_Plugin::factory('admin/write-post.php')->bottom = array('Editor', 'edit'); Typecho_Plugin::factory('admin/write-page.php')->bottom = array('Editor', 'edit'); class Editor { public static function edit() { echo "<script src='" . Helper::options()->themeUrl . '/typecho/editor/joe.extend.js' . "'></script>"; echo "<script src='" . Helper::options()->themeUrl . '/typecho/editor/joe.editor.js' . "'></script>"; } } The following joe.extend.js is neither compressed nor encrypted. The following is the source code of joe.extend.js
(function ($) { $.fn.extend({ /*Press the keyboard to insert content*/ shortcuts: function () { this.keydown(function (e) { var _this = $(this); e.stopPropagation(); if (e.altKey) { switch (e.keyCode) { case 67: _this.insertContent('[code]' + _this.selectionRange() + '[/code]'); break; } } }); }, /*Insert Content*/ insertContent: function (myValue, t) { var $t = $(this)[0]; if (document.selection) { this.focus(); var sel = document.selection.createRange(); sel.text = myValue; this.focus(); sel.moveStart('character', -l); var wee = sel.text.length; if (arguments.length == 2) { var l = $t.value.length; sel.moveEnd('character', wee + t); t <= 0 ? sel.moveStart('character', wee - 2 * t - myValue.length) : sel.moveStart('character', wee - t - myValue.length); sel.select(); } } else if ($t.selectionStart || $t.selectionStart == '0') { var startPos = $t.selectionStart; var endPos = $t.selectionEnd; var scrollTop = $t.scrollTop; $t.value = $t.value.substring(0, startPos) + myValue + $t.value.substring(endPos, $t.value.length); this.focus(); $t.selectionStart = startPos + myValue.length; $t.selectionEnd = startPos + myValue.length; $t.scrollTop = scrollTop; if (arguments.length == 2) { $t.setSelectionRange(startPos - t, $t.selectionEnd + t); this.focus(); } } else { this.value += myValue; this.focus(); } }, /*Select*/ selectionRange: function (start, end) { var str = ''; var thisSrc = this[0]; if (start === undefined) { if (/input|textarea/i.test(thisSrc.tagName) && /firefox/i.test(navigator.userAgent)) str = thisSrc.value.substring(thisSrc.selectionStart, thisSrc.selectionEnd); else if (document.selection) str = document.selection.createRange().text; else str = document.getSelection().toString(); } else { if (!/input|textarea/.test(thisSrc.tagName.toLowerCase())) return false; end === undefined && (end = start); if (thisSrc.setSelectionRange) { thisSrc.setSelectionRange(start, end); this.focus(); } else { var range = thisSrc.createTextRange(); range.move('character', start); range.moveEnd('character', end - start); range.select(); } } if (start === undefined) return str; else return this; } }); })(jQuery); The shortcuts method above is mainly used to insert content by pressing the keyboard
