将Emoji表情添加到项目中

哈哈，进入正题，项目需要发emoji表情，于是，我的任务开始了~

效果图镇楼

选择完需要的表情，点击消息预览就可以看到效果了，有一个微笑表情是QQ表情~~ 可以不用管它。

找了跟emoji相关了好多插件，找到了 jQuery_EmojiPicker 这个插件，然后研究了一下。

插件修改

1.插件初始化后将其原本的输入框隐藏。

index.html，67行。

<script>
    $(function() {
      // Initializes and creates emoji set from sprite sheet
      window.emojiPicker = new EmojiPicker({
        emojiable_selector: '[data-emojiable=true]',
        assetsPath: 'lib/img/',
        popupButtonClasses: 'fa fa-smile-o'
      });
      // Finds all elements with `emojiable_selector` and converts them to rich emoji input fields
      // You may want to delay this step if you have dynamically created input fields that appear later in the loading process
      // It can be called as many times as necessary; previously converted input fields will not be converted again
      window.emojiPicker.discover();
	  $(".emoji-wysiwyg-editor").hide();
    });
  	</script>

2.点击某个表情小图标时，将值写入指定控件。

jquery.emojiarea.js，617行。

this.$menu.on('click', 'a', function(e) {
      self.emojiarea.updateBodyPadding(self.emojiarea.$editor);
			/*
			 * ! MODIFICATION START Following code was modified by Andre Staltz,
			 * to capture clicks on category tabs and change the category
			 * selection.
			 */
			if ($(this).hasClass('emoji-menu-tab')) {
				if (self.getTabIndex(this) !== self.currentCategory) {
					self.selectCategory(self.getTabIndex(this));
				}
				return false;
			}

			/* ! MODIFICATION END */
			var emoji = $('.label', $(this)).text();
			window.setTimeout(function() {
				self.onItemSelected(emoji);
				alert(emoji);
				/*
				 * ! MODIFICATION START Following code was modified by Igor
				 * Zhukov, in order to close only on ctrl-, alt- emoji select
				 */
				if (e.ctrlKey || e.metaKey) {
					self.hide();
				}
				/* ! MODIFICATION END */
			}, 0);
			e.stopPropagation();
			return false;
		});

3.emoji.css，55行。

将icon的 position: relative; 去掉。

.emoji-picker-icon {
right: 10px;
top: 5px;
font-size: 20px;
opacity: 0.7;
z-index: 100;
transition: none;
color: black;
-moz-user-select: none;
-khtml-user-select: none;
-webkit-user-select: none;
-o-user-select: none;
user-select: none;
}
