How can I close a modal in Angular 2?

问题

I want user click the Submit button and the modal close automatically.

If I add data-dismiss="modal" in the Submit <button>, it won't run submitComments().

I tried to do something like $('#myModal').modal('hide');, but not succeed.

So how can I close a modal in Angular 2? Thanks

<button type="button" class="btn btn-info" data-toggle="modal" data-target="#myModal">Open Modal</button>

<div id="myModal" class="modal fade">
     <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <form (ngSubmit)="submitComments()">
                    <div class="form-group row">
                        <label class="form-control-label col-sm-2">Comments:</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" rows="3"></textarea>
                        </div>
                    </div>
                    <div class="form-group row">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="submit" class="btn btn-default">Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

.

submitComments() {
    // I want to do something like $('#myModal').modal('hide'); here.
}

Apart from the @MattScarpino's answer another alternative is just change your button type to button from submit and call your function submitComments() and at the same time call dismiss-modal. by doing so you able to dismiss modal and call function too at the same time hope this may help you. here is example:

<button type="button" class="btn btn-info" data-toggle="modal" data-target="#myModal">Open Modal</button>

<div id="myModal" class="modal fade">
     <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <form>
                    <div class="form-group row">
                        <label class="form-control-label col-sm-2">Comments:</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" rows="3"></textarea>
                        </div>
                    </div>
                    <div class="form-group row">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="button" (click)='submitComments()' data-dismiss="myModal" class="btn btn-default">Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

Update

if you wish to close modal from your controller side you can use using this way

$("#myModal").modal("hide");

回答2:

You can do it by simply declaring jQuery variable with any type inside Angular2 controller.

declare var jQuery:any;

Add this just after import statements and before component decorator.

Then access bootstrap modal with it's id like this.

jQuery("#myModal").modal("hide");

Using @ViewChild

add #closeBtn to the element with data-dismiss="modal"

<a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>

Component html

<div class="modal fade" id="yourModalId">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      <div class="modal-header">
        <a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>
      </div>
      <div class="modal-body">
      </div>
      <div class="modal-footer">
      </div>
    </div>
  </div>
</div>

using this.closeBtn.nativeElement.click(); to trigger click event will close your modal.

Component typescript

import {ViewChild, ElementRef} from '@angular/core';
@Component({
    moduleId: ...,
    selector: '.',
    templateUrl: '.',
    styleUrls: ['.']
})
export class yourClass {
    @ViewChild('closeBtn') closeBtn: ElementRef;

    yourFunction() {
        //do something
        ...
        ...
        //close your modal
        this.closeModal();
    }

    //call this wherever you want to close modal
    private closeModal(): void {
        this.closeBtn.nativeElement.click();
    }
}

First, set the div's hidden property equal to a variable:

<div id="myModal" [hidden]="hideModal" class="modal fade">

Second, in the class, define a boolean named hideModal and set it to false:

hideModal: boolean = false;

Third, in submitComments(), set hideModal to true.

Perfect answer in this universe.........................

step 1 : give unique id to the dismiss button of modal

step 2 : after successfully submitted form or finishing task call

document.getElementById("addProductCloseButton").click();

in your class

回答6:

Try not to include the form in your modal body instead add two buttons for the same in your footer section.

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true"><span aria-hidden="true">&times;</span></button>
          </div>
          <div class="modal-body">
    <label class="form-control-label col-sm-2">Comments:</label>
                    <div class="col-sm-10">
                        <textarea class="form-control" rows="3"></textarea>
                    </div>
          </div>
          <div class="modal-footer">
            <button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Close</button>
            <button type="submit" class="btn btn-primary" >Save changes</button>
          </div>
        </div>
      </div>
    </div>

I have done it like this and it works for me perfectly.

var element = document.getElementById("CloseButton") as any;

element.click();

Where my CloseButton is bootstrap close button.

Just declare an id = "close_model" in dismiss button and put this code in the function where you want to close the model ::

window.document.getElementById("close_model").click() ;
