как получить значения строк таблицы bootstrap при нажатии кнопки bootstrap modal

Question

Я использую ember js с bootstrap , у меня есть таблица, использующая 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>

теперь, когда кто-то нажимает на строку таблицы, я показываю bootstrap modal для подтверждения

  <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>

и я хочу, чтобы эти сведения о щелкнутых строках были в ember, чтобы я мог обработать их на сервере

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

кто-нибудь может сказать мне, как получить сведения о щелкнутой строке в ember

Answer 1

Есть две проблемы, которые необходимо решить: передача выбранного объекта/модели в событии (например, при нажатии кнопки "Одобрить"), возможность использовать сложный шаблон в качестве содержимого модального (например, при нажатии на строку модальное может содержать форму или данные из основной детали(s) отношения).

Одним из подходов было бы обновлять содержимое модального элемента каждый раз, когда происходит выделение в строке.Выделение может быть обработано при щелчке по строке, а обновление (возможно, расширенного / сложного) содержимого модального элемента может быть достигнуто путем присвоения ему шаблона и привязки его отображения к свойству.

В следующем примере для простоты был использован partial шаблон для хранения содержимого модала и простых объектов с одним свойством (name) в качестве модели.

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.
