项目中新功能需要用到富文本编辑,查找了几个富文本编辑器,结合需求以及以后产品说的可能扩展,最终选择了ueditor
首先就是功能超多,一步到位,估计都不用二次开发就够用了:
使用的话,首先要装包:
(
npm install ngx-ueditor --save)
然后就是引入到模块,然后配置前端配置项:
这是目录结构(没有在根目录引入,就为了写demo):
接着就是这个 ueditor 这个文件夹,需要去对应地址去下载: https://ueditor.baidu.com/website/download.html ,引用配置就完成了。
这时候如果想看demo,可以直接打开demo.html,就能直接看见了效果了,没有demo.html 的话,就自己创建一个,放在如上图路径下:
<!DOCTYPE HTML> <html lang="en-US"> <head> <meta charset="UTF-8"> <title>ueditor demo</title> </head> <body> <!-- 加载编辑器的容器 --> <script id="container" name="content" type="text/plain">这里写你的初始化内容</script> <!-- 配置文件 --> <script type="text/javascript" src="ueditor.config.js"></script> <!-- 编辑器源码文件 --> <script type="text/javascript" src="ueditor.all.js"></script> <!-- 实例化编辑器 --> <script type="text/javascript"> var ue = UE.getEditor(\'container\'); </script> </body> </html>
然后是使用配置(创建一个组件,在html界面中直接引用):
ts 文件中使用创建相应变量及设置配置,如果不传配置的话,会默认使用:ueditor.config.js 文件:
在模块中引入该组件,ng serve 启动项目,就能看到配置好的功能啦:
ueditor 有很多个api,可以直接获取到带html的编辑器中输入的全部内容,可以直接使用相应方法来解析带html 标签的字符串。我这里使用的是 [innerHtml] ,但innerHtml 不能解析元素的内联样式,于是乎,用管道:
页面解析时:
最终实践代码(服务是没用到的):
u-editor.component.html:
<div class="ueditor-box"> <ueditor [(ngModel)]="full_source" [config]="ueditor_config" (onReady)="onReady($event)" #full></ueditor> <div class="btn-group"> <pre class="show-message">{{showMessage}}</pre> <div [innerHTML]="showMessage | html" class="final-display"></div> <h2>语言转换</h2> <hr/> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="languageChange($event, \'zh-cn\')"> <span>zh-cn</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="languageChange($event, \'en\')"> <span>en</span> </button> <hr/> <h2>常用API</h2> <hr/> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setContent($event)"> <span>写入内容</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setContent($event, true)"> <span>追加内容</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="insertContent($event)"> <span>光标处插入给定的内容</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="insertImage($event)"> <span>插入图片</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="hasContents($event)"> <span>判断是否有内容</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="getAllHtml($event)"> <span>获得整个html的内容</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="getContent($event)"> <span>获得内容(带html标签)</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="getContentTxt($event)"> <span>获得纯文本</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="getPlainTxt($event)"> <span>获得带格式的纯文本(能获得但显示需处理)</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="getText($event)"> <span>获得当前选中的文本(暂时有问题)</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="onfocus($event)"> <span>使编辑器获得焦点</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="onblur($event)"> <span>使编辑器失去焦点</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="isOnFocus($event)"> <span>判断编辑器是否有焦点</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setEnabled($event)"> <span>编辑器可以编辑</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setDisabled($event)"> <span>编辑器不可编辑</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setHide($event)"> <span>隐藏编辑器</span> </button> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setShow($event)"> <span>显示编辑器</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="setHeight($event)"> <span>设置编辑器的高度为300</span> </button> <br> <button class="btn-search" nz-button [nzType]="\'primary\'" [nzSize]="\'normal\'" (click)="clearDoc($event)"> <span>清空文档</span> </button> </div> </div>

好啦,就先这些,如果要用到各种上传什么的,则需要配置后端服务。。。
引一下git:https://github.com/cipchk/ngx-ueditor
官网:http://fex.baidu.com/ueditor/#start-config
还有一个 ngx-umeditor 的: https://github.com/cipchk/ngx-umeditor 也可以看看,感觉像是优化版?
