今天在头条上看到推送的这个ContentTools文章,一眼就相中了它。可视化前端编辑插件ContentTools所见即所得,看起来是我想要的效果,下面一起看看这款JavaScript插件是怎么使用的吧!
首先下载插件资源,这是开源项目,源码在GitHub上,地址是:https://github.com/GetmeUK/ContentTools
下载后我们找到压缩包中build目录,里面的资源是我们需要的。
下面新建项目,结构如下:
/site /assets /images - ce-drop-above.png - ce-drop-below.png - ce-drop-left.png - ce-drop-right.png - video.png - content-tools.min.js - content-tools.min.css - icons.woff
准备HTML
<div data-editable data-name="main-content"> <blockquote> Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. </blockquote> <p>John F. Woods</p> </div> <h1 data-editable data-name="heading">Content</h1> <div data-editable data-name=heading> <h1>Content</h1> </div>
js初始化
var editor = ContentTools.EditorApp.get(); editor.init('*[data-editable]', 'data-name');
JavaScript将根据选择器选择的元素初始化编辑区域,以便编辑器编辑。
还可以为编辑器添加保存或取消事件。
editor.addEventListener('saved', function (ev) { var name, payload, regions, xhr; // Check that something changed regions = ev.detail().regions; if (Object.keys(regions).length == 0) { return; } // Set the editor as busy while we save our changes this.busy(true); // Collect the contents of each region into a FormData instance payload = new FormData(); for (name in regions) { if (regions.hasOwnProperty(name)) { payload.append(name, regions[name]); } } // Send the update content to the server to be saved function onStateChange(ev) { // Check if the request is finished if (ev.target.readyState == 4) { editor.busy(false); if (ev.target.status == '200') { // Save was successful, notify the user with a flash new ContentTools.FlashUI('ok'); } else { // Save failed, notify the user with a flash new ContentTools.FlashUI('no'); } } }; xhr = new XMLHttpRequest(); xhr.addEventListener('readystatechange', onStateChange); xhr.open('POST', '/save-my-page'); xhr.send(payload); });
当用户保存页面时,我们使用Ajax将每个区域的内容发送到服务器,当然你可以不保存到服务器。
