I am trying to use bootstrap-datepicker with Vue.js Trying to create a simple datepicker component. The problem is, when I write into input, component's data is updated. But when I use datepicker gui, it doesn't work. Data is not updated. Why? What is missing exactly?
Here is my code:
Vue.component('picker', {
'props': {
'date': {
'twoWay': true
}
},
'template': '\
<div class="form-group">\
<div class="input-group date datepicker">\
<input type="text" class="form-control" v-bind:value="this.date">\
<span class="input-group-addon">\
<span class="glyphicon glyphicon-calendar"></span>\
</span>\
</div>\
</div>',
'watch': {
'date': function(value) {
console.log('Updated!');
}
},
'mounted': function() {
$(this.$el.firstChild).datetimepicker();
}
});
app = new Vue({
'el': '#app',
'data': {}
});<!DOCTYPE html>

I couldn't find a better way than losing focus (blur).
Here's my code:
Vue.component('picker', {
'props': ['date'],
'template': '\
<div class="form-group">\
<div class="input-group date datepicker">\
<input type="text" class="form-control" :value="this.date" v-on:focus="datepick_dialog_open" v-on:blur="select_by_lose_focus">\
<span class="input-group-addon">\
<span class="glyphicon glyphicon-calendar"></span>\
</span>\
</div>\
</div>',
'mounted': function() {
$(this.$el.firstChild).datetimepicker();
},
'methods': {
'datepick_dialog_open': function() {
this.$el.firstChild.children[1].click();
},
'select_by_lose_focus': function() {
console.log('AHOY!');
this.date = this.$el.firstChild.firstChild.value;
}
}
});
app = new Vue({
'el': '#app',
'data': {}
});
The point is, you really can't use it if your element does not lose focus. It updates the data when input loses its focus. IDK any better way.
v-on:focus is irrelevant. It just opens the datetime picker UI when input gains focus.
The main job is done by select_by_lose_focus.

Another example using $emit and v-model on the component. This page describes why value and $emit are needed to support v-model. I needed a form element name and optional required class for validation.
https://v2.vuejs.org/v2/guide/components.html#Form-Input-Components-using-Custom-Events
<picker name="start_date_1_1" required="1" v-model="res.start_date"></picker>
Vue.component('picker', {
props: ['name', 'value', 'required'],
template: '\
<div class="form-group">\
<div class="input-group date">\
<input :name="name" type="text" class="form-control" v-bind:class="{required: required}" v-bind:value="value">\
<span class="input-group-addon">\
<span class="glyphicon glyphicon-calendar"></span>\
</span>\
</div>\
</div>',
mounted: function() {
var self = this;
var picker = $(this.$el.firstChild).datepicker({autoclose: true});
picker.on('changeDate', function(e) {
self.$emit('input', e.date.toLocaleDateString("en-US", {day: '2-digit', month: '2-digit', year: 'numeric'}));
});
}
});
Add before vue object init:
Vue.directive('vueinput', {
twoWay: true,
bind: function (el, binding, vnode) {
$(el).on("change", (e) => {
el.dispatchEvent(new Event('input', { target: e.target }));
});
},
});
And then add v-vueinput="[uniqueString]" directive to your datetime input:
<div data-start-view="4" data-min-view="2" class="input-group date datetimepicker">
<input type="text"
v-model="payment.pay_date"
v-vueinput="payment.pay_date">
<div class="input-group-append">
<button class="btn btn-primary"><i class="icon-th mdi mdi-calendar"></i></button>
</div>
</div>
I recommend to put same value as v-model to this directive ('payment.pay_date' in my example)
You can use unlimited entities of inputs with this directives on one page.
