Once you've added the trigger, you will need to create a new instance of LIVECHATSDK.LIVECHAT.emojiPicker EmojiButton object class.
| Code Block | ||
|---|---|---|
| ||
LIVECHATSDK.SDK.getEmojiPicker().then ( function(emojiClass) { window.emoji_picker = new LIVECHATSDKemojiClass.LIVECHAT.emojiPickerEmojiButton( { "position": "auto", "showPreview": false, "recentsCount": 6, "autoHide": false, "showVariants": false, "autoFocusSearch": true, "emojiSize": "1.2em", "emojisPerRow": 6, "emojiVersion": "11.0", "categories": ["smileys", "people", "animals", "food", "activities", "travel", "objects", "symbols"], "zIndex": 10000, "showAnimation": true } ); } ); |
After constructing a picker, it can be shown by calling showPicker or togglePicker on it methods. These functions expect a reference element as a parameter. The picker is positioned relative to this reference element according the “position” parameter.
You can also use a static positioning by specifying x/y coordinates in the constructor options parameters.
| Code Block | ||
|---|---|---|
| ||
jQuery("#btnEmoji").off().on("click", function() {
if ( window.emoji_picker.pickerVisible == true) {
window.emoji_picker.hidePicker();
} else {
window.emoji_picker.showPicker( jQuery("#btnEmoji").get() );
}
}); |
When an emoji is selected, the picker will emit an emoji event, passing an object containing data about the emoji that was selected. There also a “hidden” event to notify when the picker has been closed.
| Code Block | ||
|---|---|---|
| ||
window.emoji_picker.on("emoji", function (event) {
// Append Unicode Emoji to a textarea
jQuery("#textareaChat").val( jQuery("#textareaChat").val() + event.emoji);
});
window.emoji_picker.on("hidden", function (event) {
// Hidden event fired
}); |

Customize Picker Control
Relative Positioning
The picker accepts an option specifying where the picker should be positioned, relative to the reference element passed to showPicker or togglePicker. This property can be any of the following values:
auto, auto-start, auto-end, top, top-start, top-end, bottom, bottom-start, bottom-end, right, right-start, right-end, left, left-start, left-end
Fixed Positioning
A fixed position can also be given for the position option. In this case, position is an object with top, bottom, left, and/or right properties.

|---|---|---|

position: {
top: '0',
right: '0'
} |
