Using BotUI (Docs) I'd like to have the loading animation, which is displayed before messages appear, also displayed before actions (e.g. buttons) appear.
var botui = new BotUI('hello-world');
botui.message.add({
content: 'Hello world from bot!'
}).then(function() {
return botui.message.add({
delay: 3000,
human: true,
content: 'Hello world from human!'
});
}).then(function() {
return botui.message.add({
delay: 3000,
content: 'Another hello world from bot!'
});
}).then(function() {
return botui.message.add({
delay: 3000,
human: true,
content: 'Another hello world from human!'
});
}).then(function () {
return botui.action.button({
delay: 3000,
action: [{
text: 'Some button',
value: 'button1'
}, {
text: 'Another button',
value: 'button2'
}]
});
}).then(function (res) {
if(res.value == 'button1') {
console.log('Some button was clicked.');
}
if(res.value == 'button2') {
console.log('Another button was clicked.');
}

</div>At least I managed to identify the relevant template part in botui.js.
<div v-if=\"msg.loading\" class=\"botui-message-content loading\"><i class=\"dot\"></i><i class=\"dot\"></i><i class=\"dot\"></i></div>
But since the contents of the botui-actions-container are loaded only after the delay I am unable to display the loading animation before the buttons appear.
You are trying to change the inner working of a third party component. This is normally a bad practice. In this case probably the best way is to open a new issue on their Github repository. Ask them exactly what you need and maybe they will implement the requested feature for you.
This can be done without changing the inner working of BotUI, by using botui.message.add (to use the loading feature) immediately followed by botui.message.remove using the index parameter of the last message. Then use the action you want. This makes the loading appears before the action as requested, despite botui.action not having a loading parameter.
Here is the code that I use, with botui.action.button, but you can use any action. If you use delay: 0 for the action, the action appears instead of the loading, without any blank message that would appear if you do not remove the initial message.
// add an empty message to use the "loading" feature not available with action
botui.message.add({
delay: 2000,
loading: true,
content: ''
}).then(function (index) {
// get the index of the empty message and delete it
botui.message.remove(index);
// display action with 0 delay
botui.action.button({
delay: 0,
action: [{
text: 'Action 1',
value: 'a1'
}, {
text: 'Action 2',
value: 'a2'
}]
}).then(function (res) {
botui.message.bot({
delay: 1000,
content: 'action chosen: ' + res.value
});
});
});
