在textarea里输入:弹出emoji并选择上屏

用github的issues回复的时候，可以直接输入:就会自动弹出emoji，可以选择并上屏，非常的方便，网上找了一下，大都是用图片实现的，这不是我想要的，本来emoji就是一个字符，而且各个平台都支持，那为啥不直接输入emoji呢？不用图片替换可以吗？然后折腾了一下，实现了！！

先上图看看效果

引入依赖

这个功能用的是 at.js 实现的, at.js又依赖 Caret.js , 所以两个js都要引入

另外还有at.js的css文件也要引入

下面我用的是bootcdn的链接，你可以用自己的链接

初始化

就是按照github/wiki上的demo改的，直接拷贝就可以用了

var cOntentE= $("#content");

contentE.atwho({
  at: ":",
  data: [
    {'name': 'Grinning Face', 'emoji': ':grinning:'},
    {'name': 'Grinning Face With Smiling Eyes', 'emoji': ':grin:'},
    {'name': 'Face With Tears of Joy', 'emoji': ':joy:'},
    {'name': 'Rolling on the Floor Laughing', 'emoji': ''},
    {'name': 'Smiling Face With Open Mouth', 'emoji': ':smiley:'},
    {'name': 'Smiling Face With Open Mouth & Smiling Eyes', 'emoji': ':smile:'},
    {'name': 'Smiling Face With Open Mouth & Cold Sweat', 'emoji': ':sweat_smile:'},
    {'name': 'Winking Face', 'emoji': ':wink:'},

    {'name': 'Relieved Face', 'emoji': ':relieved:'},
  ],
  displayTpl: function (data) {
    return '
' + data.emoji + ' ' + data.name + "
";
  },
  insertTpl: function (data) {
    return data.emoji;
  }
});
