首先看下效果图
使用方法
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>";
}
}
下面的 joe.extend.js 没压缩也没加密,下面是 joe.extend.js 源码
(function ($) {
$.fn.extend({
/* 按键盘实现插入内容 */
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;
}
}
});
},
/* 插入内容 */
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();
}
},
/* 选择 */
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);
上面的shortcuts方法主要用于实现按下键盘插入内容
接着看 joe.edit.js
的内容

const items = [
