第二步引入资源实现初步效果:
1.项目下创建js文件夹
2.解从下载好的压缩包解marked/lib下的marked.js到js文件夹
3.解从下载好的压缩包解ace-builds/src到js文件夹重命名为ace
4.引入js文件
(注:markdown.css是markdown样式文件,可以自行编写或从网上下载比如:github-markdown-css)
<!DOCTYPEhtml><html>
<head>
<metacharset='UTF-8'>
<title>markdown编辑器</title>
<scriptsrc="js/jquery-2.1.4.min.js"></script>
<scriptsrc="js/marked.js"></script>
<scriptsrc="js/ace/ace.js"></script>
<linkhref="markdown.css"rel="stylesheet"/>
<!--略-->
5初始化插件
(先添加编辑区和显示区代码)
<!--略-->#mdeditor#preview,#panel-editor,#panel-preview{
height:100%;
width:100%;
}</style>
</head>
<body>
<divid='toolbar'></div>
<divid='container'><divid='editor-column'class='pull-left'>
<divid='panel-editor'>
<!--编辑区-->
<divclass="editor-content"id="mdeditor"></div>
</div>
</div>
<divid='preview-column'class='pull-right'>
<divid='panel-preview'>
<!--显示区-->
<divid="preview"class="markdown-body"></div>
</div>
</div>
<!--略-->
(先添加初始化代码)
<!--略-->
varacen_edit=ace.edit('mdeditor');
acen_edit.setTheme('ace/theme/chrome');
acen_edit.getSession().setMode('ace/mode/markdown');
acen_edit.renderer.setShowPrintMargin(false);
$("#mdeditor").keyup(function(){
$("#preview").html(marked(acen_edit.getValue()));
});
第三步添加工具到工具栏示例:
1.编写公用方法
(其实点击工具主要是在编辑器里自动插入本来手打的符号)
functioninsertText(val){
acen_edit.insert(val);//光标位置插入
}
<divid='toolbar'>
<buttononclick="insertText('**?**')">加粗</button>
<buttononclick="insertText('_?_')">斜体</button>
<buttononclick="insertText('>')">引用</button>
.....</div>
第四步ace.jsAPI实现编辑器设置功能:
<divid='toolbar'>
<buttononclick="insertText('**?**')">加粗</button>
<buttononclick="insertText('_?_')">斜体</button>
<buttononclick="insertText('>')">引用</button>.....设置:<selectid="theme"size="1">
