AngularJS无法与Paypal一起使用

Question

I'm working in a project that I have to integrate angular with paypal plus. But when I put the script (paypal script) in a HTML the angular doesn't recognize the PAYPAL.apps.PPP script's variable I receives this error at console.

angular.js:13550 ReferenceError: PAYPAL is not defined

HTML code:

<script src="https://www.paypalobjects.com/webstatic/ppplus/ppplus.min.js" type="text/javascript"></script>
<script type="application/javascript">
var ppp = PAYPAL.apps.PPP({"approvalUrl": '.$approvalUrl.',"placeholder": "ppplus","mode": "sandbox"});
</script>
<div id="ppplus"> </div>
<button type="submit"
id="continueButton"
onclick="ppp.doContinue(); return false;">Continuar
</button>

Someone here know how to integrate paypal with angular or imports others scripts to be used in application. o/

Answer 1

It seems like the paypal js is not getting loaded or the angular script is running before it is loaded.

I put the script in the html index.html :)

Answer 2

您需要添加jQuery库。您应该在PAYPAL库之前添加它。

Answer 3

I'm working in a project with Angular 5 and I'd like to share my (almost) final solution to integrate Paypal Plus folowing the tipps from @Gleidson Ferreira.

On the head of the index.html:

<script src="https://www.paypalobjects.com/webstatic/ppplus/ppplus.min.js" type="text/javascript"></script>

On the checkout.component.ts:

import { Component, OnInit } from '@angular/core';
declare var PAYPAL: any;

@Component({
    selector: 'checkout',
    templateUrl: './checkout.component.html'
})
export class CheckoutComponent implements OnInit {
    paypalPlus: any;

    ngOnInit() {

    // TODO: add further customization to get your own proval URL dinamically
    this.paypalPlus = PAYPAL.apps.PPP(
    {
     'approvalUrl': 'https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-31737613MN931841V',
      'placeholder': 'ppplus',
       'mode': 'sandbox'
    });
}

}

On checkout.component.html:

<div class="row" id="ppplus"> </div>
