I have a component that has a text field, like this
<div>
{{input type='text' insert-newline='postMessage' class="form-control" autofocus="true"}}
<input type="hidden" name="uid" value={{room.uid}}/>
</div>
the component that have this snippet, lives inside a route called room
export default Ember.Route.extend({
model(params){
this.store.findRecord('room', params.uid);
}
});
to handle the action in the input, I created a controller for the room:
app/controllers/room.js
import Ember from 'ember';
export default Ember.Controller.extend({
actions: {
postMessage(params){
console.log(params);
}
}
});
but when I hit enter, I get this error:
Uncaught Error: <chathub-ember#component:chat-room::ember1071> had no action handler for: postMessage
I tried to put this action in the route as well and didn't worked
In the room.hbs file,
{{my-component myAction='postMessage'}}
and then in my-component.js
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
postMessage(params) {
this.sendAction('myAction', params);
}
}
})

How can we get the original event in ember action while handling action inside controller?
Controller
import Ember from 'ember';
export default Controller.extend({
showDetails:function(id)
{
// I want like $(this).position().top
}
});
Template
{{#each item in list}}
<em {{action "showDetails" item.id bubbles=false}}></em>
{{/each}}
{{#each item in list}}
<em onclick={{action "showDetails" item.id}}></em>
{{/each}}
In controller,
import Ember from 'ember';
export default Controller.extend({
actions: {
showDetails(id, event) {
//i want like $(this).position().top
}
}
});
Changing isOpen property in route should reflect it in my component. How can we accomplish this ?.
Ember-Twiddle
routes/application.js
import Ember from 'ember';
export default Ember.Route.extend({
isOpen:true,
setupController(controller,model){
this._super(...arguments);
controller.set('isOpen',this.get('isOpen')); //whenever i set route property, will this update controller?
console.log('setupController');
},
actions:{
toggleOpen(){
console.log('before toggle - ',this.get('isOpen'));
this.toggleProperty('isOpen'); //changing this route property is not reflected in controller.
//this.controller.toggleProperty('isOpen'); //changing controller is reflecting.
console.log('after toggle - ',this.get('isOpen'));
}
}
});
controllers/application.js
import Ember from 'ember';
export default Ember.Controller.extend({
appName: 'Ember Twiddle'
});
templates/application.hbs
<h1>Welcome to {{appName}}</h1>
<br>
{{isOpen}}
{{my-component isOpen=isOpen toggleOpen='toggleOpen'}}
<br>
{{outlet}}
<br>
<br>
templates/components/my-component.hbs
my-component {{isOpen}}
<button {{action 'toggleOpen'}}> Toggle </button>
{{yield}}
components/my-component.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
toggleOpen(){
this.sendAction('toggleOpen');
}
}
});
Because isOpen is a primitive typed property. No matter if it was an object. Sample Twiddle.
Or more simplistic one.
I am trying to call an action from a parent component in my route view.
mychild.hbs
{{#parent as |wrapper|}}
<button {{action "animate"}}>Login</button>
{{/parent}}
parent.hbs
<div>{{yield}}</div>
mychild route (no actions)
export default Ember.Route.extend(
});
mychild controller
export default Ember.Controller.extend({
});
parent component
export default Ember.Component.extend({
actions: {
animate() {
console.log('ok');
}
},
});
How to call animate() from my component ? What am I doing wrong ?
Changed the following code to this. Seems to be working.
<div>
{{yield this}}
</div>
{{#my-component as |mc|}}
<button {{action "doIt" target=mc}}>callDoIt</button>
{{/my-component}}
My click-editable component like:
Template:
{{#if isEdit}}
<div class="input-group">
{{input type="text" value=editValue class="form-control"}}
<div class="input-group-btn">
<button type="button" class="btn no-margin-btn btn-info" {{action "updateValue"}}>{{fa-icon 'check'}}</button>
</div>
</div>
{{else}}
....
{{/if}}
And:
export default Ember.Component.extend({
tagName: "",
isEdit: false,
canEdit: true,
category: 'input',
editValue: Ember.computed.oneWay('value'),
actions:{
updateValue() {
this.sendAction('onUpdate', this.get('valueModel'), this.get('valueColumn'), this.get('editValue'), this.get('isEdit'));
}
}
});
Use in my template:
{{#each model.quotationWorkItems as |quotationWorkItem index|}}
{{click-editable valueModel=quotationWorkItem valueColumn='name' value=quotationWorkItem.name onUpdate=(action "updateInput")}}
{{/each}}
In the controller:
import Ember from 'ember';
export default Ember.Controller.extend({
....
actions: {
updateInput(updateModel, updateColumn, value, isEdit) {
updateModel.set(updateColumn, value);
updateModel.save().then(()=> {
this.get('model').reload();
this.set('isEdit', false);
}, ()=> {
alert('wrong');
});
}
}
})
Route:
import Ember from 'ember';
export default Ember.Route.extend({
...
model(params) {
return this.store.find('quotation', params.quotation_id);
},
setupController(controller, model) {
controller.set('model', model);
...
}
})
Quotation model:
import DS from 'ember-data';
export default DS.Model.extend({
quotationStocks: DS.hasMany('quotationStock'),
quotationWorkItems: DS.hasMany('quotationWorkItem'),
...
});
QuotationWorkItem model:
import DS from 'ember-data';
export default DS.Model.extend({
transactionType: DS.belongsTo('transactionType'),
quotation: DS.belongsTo('quotation'),
...
});
This code can update model value, but problem isEdit is the component value. When isEdit send to controller and set another value, it can not work. So I think can not change component value in ember controller?
this.set('isEdit', false);
The code can not work in controller. I'm using Ember 2.4.0.
You need to bind the controller isEdit property to the component isEdit property.
{{click-editable isEdit=isEdit valueModel=quotationWorkItem valueColumn='name' value=quotationWorkItem.name onUpdate=(action "updateInput")}}
This will overwrite the isEdit property in the component (data down).
I'm trying to work with a simple overlay component, and close this overlay if someone clicks outside of the overlay content:
<div class="overlay" {{action 'close' on='click'}}>
<div class="item">
<form {{action 'submit' on='submit'}}>
{{yield}}
{{#link-to closeRoute class="close"}}Close{{/link-to}}
</form>
</div>
</div>
The component looks like this:
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
submit: function() {
this.sendAction();
},
close: function(param) {
console.log(param); // -> undefined
console.log(this); // -> complete component object, no reference to the event?
// this.$("a.close").click();
}
}
});
This works like advertised, however, I need to determine the target of the click event, because also clicks on the item and form will trigger this click(close) action.
Question: How can I access the (jQuery) event object which has a target from within the close action inside the component?
I am using EmberCLI, and Ember 1.9
I have found this to provide the required result:
export default Ember.Component.extend({
classNames: ['overlay-block'],
didInsertElement: function() {
var self = this;
self.$().click(function(e) {
if (self.$(e.target).hasClass("overlay-block")) {
self.$("a.close").click();
}
});
}
});
This does not use an ember action like I expected. I'll leave the question open for a while to see if somebody comes up with an more 'Ember way' of doing this.
More Ember way
export default Ember.Component.extend({
classNames: ['overlay-block'],
click: function(e) {
if (this.$(e.target).hasClass("overlay-block")){
this.$("a.close").click();
}
}
});
