quill 富文本编辑器 @提及

使用插件quill-mention，实现在quill 富文本编辑器使用@或#提及用户。

1. 安装

npm install quill-mention --save

2. 官方给的示例quill-mention

import "quill-mention";

const atValues = [
  { id: 1, value: "Fredrik Sundqvist" },
  { id: 2, value: "Patrik Sjölin" }
];
const hashValues = [
  { id: 3, value: "Fredrik Sundqvist 2" },
  { id: 4, value: "Patrik Sjölin 2" }
];
const quill = new Quill("#editor", {
  modules: {
    mention: {
      allowedChars: /^[A-Za-z0-9_]*$/,
      mentionDenotationChars: ["@", "#"],
      source: function(searchTerm, renderList, mentionChar) {
        let values;

        if (mentionChar === "@") {
          values = atValues;
        } else {
          values = hashValues;
        }

        if (searchTerm.length === 0) {
          renderList(values, searchTerm);
        } else {
          const matches = [];
          for (let i = 0; i < values.length; i++)
            if (
              ~values[i].value.toLowerCase().indexOf(searchTerm.toLowerCase())
            )
              matches.push(values[i]);
          renderList(matches, searchTerm);
        }
      }
    }
  }
});

3. 在vue2中使用的示例，已省去无关代码。(示例来自自行封装的Quill.vue通用组件)

4. 无论哪个示例，记得引入css样式。在源码的 dist/quill.mention.css

.ql-mention-list-container {
  width: 270px;
  border: 1px solid #f0f0f0;
  border-radius: 4px;
  background-color: #ffffff;
  box-shadow: 0 2px 12px 0 rgba(30, 30, 30, 0.08);
  z-index: 9001;
  overflow: auto;
}

.ql-mention-loading {
  line-height: 44px;
  padding: 0 20px;
  vertical-align: middle;
  font-size: 16px;
}

.ql-mention-list {
  list-style: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

.ql-mention-list-item {
  cursor: pointer;
  line-height: 44px;
  font-size: 16px;
  padding: 0 20px;
  vertical-align: middle;
}

.ql-mention-list-item.disabled {
  cursor: auto;
}

.ql-mention-list-item.selected {
  background-color: #d3e1eb;
  text-decoration: none;
}

.mention {
  height: 24px;
  width: 65px;
  border-radius: 6px;
  background-color: #d3e1eb;
  padding: 3px 0;
  margin-right: 2px;
  user-select: all;
}

.mention > span {
  margin: 0 3px;
}
