cómo obtener los valores de fila de la tabla de arranque al hacer clic en modal de arranque

Question

Yo usando Ember JS con Bootstrap tengo una mesa usando bootstrap

 <table class="table table-striped table-bordered table-hover">
    <thead>
      <tr>
        <th>Request Id</th>
        <th>Applied By</th>
        <th>Leave Type</th>
        <th>Leave From</th>
        <th>Leave To</th>
        <th>Days</th>
        <th>Status</th>
        <th>Applied date</th>
        <th>Applied/Declined date</th>
      </tr>
    </thead>
    <tbody data-link="row" class="rowlink">
      {{#each model.pending}}
      <tr id="ptable" data-toggle="modal" data-target="#pendingrequestsmodal" style="cursor: pointer">
        <td id="eid">{{id}}</td>
        <td>{{employee_id}}</td>
        <td>{{type_id}}</td>
        <td>{{from_date}}</td>
        <td>{{to_date}}</td>
        <td>{{days}}</td>
        <td>{{status}}</td>
        <td>{{to_date}}</td>
        <td>{{to_date}}</td>
      </tr>
      {{/each}}
    </tbody>
      </table>

Ahora, cuando alguien hace clic en la fila de la tabla, muestro el modo de arranque para confirmación.

  <div id="pendingrequestsmodal" class="modal fade">
<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Confirmation</h4>
    </div>
    <div class="modal-body">
      <button type="button" class="btn btn-default" data-dismiss="modal">Decline</button>
      <button type="button" class="btn btn-primary" {{action "pendingAction" target="controller" }}>Approve</button>
    </div>
  </div>
</div>

y quiero estos detalles de la fila en la que se hizo clic en las brasas para poder procesarlos en el servidor

App.ApprovalrequestsController = Ember.ObjectController.extend({
actions: {
pendingAction: function () {
 //here i want to get the details of clicked row 
    //this.transitionToRoute("approvalrequests", rdata);
}
}
});

¿Alguien puede decirme cómo obtener los detalles de la fila en la que se hizo clic en Ember?

Answer 1

Hay dos problemas que deben resolverse: pasar el objeto/modelo seleccionado en un evento (por ejemplo, al hacer clic en el botón aprobar) y poder usar una plantilla complicada como contenido del modal (por ejemplo, al hacer clic en una fila, el modal podría contener un formulario o datos de una relación maestro-detalle).

Un enfoque sería actualizar el contenido del modal cada vez que ocurre una selección en una fila.La selección se puede manejar al hacer clic en la fila y la actualización del contenido (posiblemente rico/complicado) del modal se puede lograr asignándole una plantilla y vinculando su representación a una propiedad.

El siguiente ejemplo por simplicidad ha utilizado un partial plantilla para contener el contenido del modal y objetos simples con una propiedad (name) como modelo.

js

App = Ember.Application.create();

App.Router.map(function() {
  // put your routes here
});

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return [{name:'red'}, {name:'yellow'}, {name:'blue'}];
  }
});

App.IndexController = Ember.ArrayController.extend({
  selectedColor:null,
  actions:{
    pendingAction:function(color){alert("the color is:"+color.name);}
  }
});

App.IndexView = Ember.View.extend({
  actions:{
    selectColor:function(color){
      this.controller.set("selectedColor",color);
    }
  }
});

Answer 2

You could specify the action on the

tr

like this:

 <tr id="ptable" data-toggle="modal" {{action 'pendingAction' this}} //blah>

Now, when a row is clicked, the controller's method in the actions hash 'pendingAction' is triggered with a parameter which is the row that was clicked on, or more precisely, the object which has materialized into the row.

Answer 3

To get this to work properly, you're going to have to change how you trigger the modal. Instead of using the Bootstrap plugin, it's much better to use Ember to handle it.

In your application template, add a second named outlet for your modal:

<script type="text/x-handlebars">
     {{outlet}}
     {{outlet modal}}
</script>

Then in your template, add a new action that will trigger the opening of the modal and pass the model along with it, like this:

<script type="text/x-handlebars data-template-name="pending">
    <tbody data-link="row" class="rowlink">
        {{#each request in model.pending}}
            <tr id="ptable"  style="cursor: pointer" {{action 'openModal' request}}>
                <td id="eid">{{item.id}}</td>
                <td>{{request.employee_id}}</td>
                <td>{{request.type_id}}</td>
                <td>{{request.from_date}}</td>
                <td>{{request.to_date}}</td>
                <td>{{request.days}}</td>
                <td>{{request.status}}</td>
                <td>{{request.to_date}}</td>
                <td>{{request.to_date}}</td>
            </tr>
        {{/each}}
    </tbody>
</script>

After that, you'll need to setup a modal template like this:

<script type="text/x-handlebars" data-template-name="pendingrequestmodal">
    <div id="pendingrequestsmodal" class="modal fade">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" {{action 'closeModal'}} aria-hidden="true">&times;</button>
                    <h4 class="modal-title">Confirmation</h4>
                </div>
                <div class="modal-body">
                {{model.id}}
                    <button type="button" class="btn btn-default" {{action 'closeModal'}}>Decline</button>
                    <button type="button" class="btn btn-primary" {{action "pendingAction" model}}>Approve</button>
                </div>
            </div>
        </div>
    </div>
    <div class="modal-backdrop" {{action 'closeModal'}}></div>
</script>

In the openModal action, we passed in the model as well. This will make it accessible when we react the to the event. You need to listen for the event and render the modal in your route, like this:

App.ApplicationRoute = Ember.Route.extend({
  actions: {
    openModal: function(request) {
      this.controllerFor('approvalrequests').set('model',request);

      return this.render('pendindrequestmodal', {
        into: 'application',
        outlet: 'modal',
        controller:'approvalrequests'
      });
    },
    closeModal: function() {
    return this.disconnectOutlet({
      outlet: 'modal',
      parentView: 'application'
    });
  }
  }
});

In the action, we're setting the modal property for our controller to the model we passed in and we're setting that controller as the controller for the modal. This will mean we can access the model properties in the template as normal. I also added the closeModal event that works by disconnecting the outlet.

Finally, we can handle the pendingAction event in your controller. In the modal, we passed the model along with the action, so it's accessible here as well.

App.ApprovalrequestsController = Ember.ObjectController.extend({
    actions: {
        pendingAction: function (model) {
            this.transitionToRoute("approvalrequests", model);
        }
    }
});

I kinda guessed on some of your template, route and controller names so they may need to be changed to fit your situation. If something here doesn't work, let me know and I can modify the answer.

You can find instructions and a working example of how to set up a modal dialogue here in the Ember Cookbook.
