配置TinyMCE让WEB端编辑器“完美”支持小程序富文本组件

最近给小程序新增了文章资讯内容,发现小程序并不能直接展示HTML代码,仅支持部分HTML节点及属性,只能被迫搞一个方便自己复制粘贴的CMS后台富文本编辑器

TinyMCE

TinyMCE是一个轻量级的基于浏览器的所见即所得HTML富文本编辑器,支持目前流行的各种浏览器,由JavaScript写成。功能配置灵活简单(两行代码就可以将编辑器嵌入网页中),支持AJAX。

因为之前项目使用过,所以直接照着搬了过来,具体怎么怎么加载js这些就不讲了,不会的自己谷歌百度~

rich-text

rich-text是小程序的富文本组件,但是微信限制了一部分能力。
它的关键属性是nodes,注意一句话:nodes 属性推荐使用 Array 类型,由于组件会将 String 类型转换为 Array 类型,因而性能会有所下降,这篇文章暂时不考虑性能问题,只支持String,如果你想支持Array,自己想办法。。
rich-text支持节点看官方文档:rich-text

TinyMCE配置

TinyMCE的配置网上很多很多了这里就不讲了,只写一下小程序rich-text用到的,代码+注释

tinymce.init({
    selector:'textarea#content',
    height: 400,
    menubar: false,
    //这些插件可以自由配置,并且可以自己定制,比如支持图片直接上传到第三方云储存
    plugins: [
        'paste,preview,fullscreen,searchreplace,code,wordcount'
    ],
    toolbar1: "fullscreen preview code",
    toolbar2: "undo redo | searchreplace",
    //只有这里配置的节点和属性,编辑器才支持,不符合的会自动过滤(下面是目前rich-text支持的所有节点和属性)
    valid_elements: "p[style|class],a[style|class],abbr[style|class],b[style|class],blockquote[style|class],br[style|class],code[style|class],col[style|class|span|width],colgroup[style|class|span|width],dd[style|class],del[style|class],div[style|class],dl[style|class],dt[style|class],em[style|class],fieldset[style|class],h1[style|class],h2[style|class],h3[style|class],h4[style|class],h5[style|class],h6[style|class],hr[style|class],i[style|class],img[style|class|alt|src|height|width],ins[style|class],label[style|class],legend[style|class],li[style|class],ol[style|class|start|type],p[style|class],q[style|class],span[style|class],strong[style|class],sub[style|class],sup[style|class],table[style|class|width],tbody[style|class],td[style|class|colspan|height|rowspan|width],tfoot[style|class],th[style|class|colspan|height|rowspan|width],thead[style|class],tr[style|class],ul[style|class]",
    //如果配置了这个,编辑器会自动抹掉节点的属性(如果要保留请设置为false)
    paste_as_text: true,
    plugin_preview_height: 670,
    plugin_preview_width: 370,
    //一个汉字算一个字符,为了统计相对准确
    wordcount_countregex: /([\w\u2019\x27\-\u00C0-\u1FFF]+)|([^\x00-\xff])/g,
    //rich-text不支持html实体,所以我们得将实体转为字符

结束

毕竟还没有长期大量使用,是不是完全没问题,不敢100%保证,如果有问题,大家随时给我反馈,啊哈哈~
