Use reference of checkbox element and pass the value or use ngModelChange



Replace the below code



<input type="checkbox" name="checkbox-i" (change)="clickOn(test.fav)" [(ngModel)]="test.fav" />


by



<input type="checkbox" name="checkbox-i" #test 
 (change)="clickOn(test.value)" [(ngModel)]="test.fav" />


or



 <input type="checkbox" name="checkbox-i" #test 
 (ngModelChange)="clickOn($event)" [(ngModel)]="test.fav" />

            Node.js Script on GitHub Pages or Amazon S3

            圖片
            0 I'm wondering if I can run a Node.js script in my Jekyll page from GitHub Pages or Amazon S3? I think it can't run on GitHub Pages since it doesn't support server side code. Not too sure. The code is below: var Airtable = require('airtable'); var base = new Airtable(apiKey: 'YOUR_API_KEY').base('appAnZVyYqusNPV5Q'); base('Invitee list').select( // Selecting the first 3 records in Complete list: maxRecords: 3, view: "Complete list" ).eachPage(function page(records, fetchNextPage) // This function (`page`) will get called for each page of records. records.forEach(function(record) console.log('Retrieved', record.get('Email')); ); // To fetch the next page of records, call `fetchNextPage`. // If there are more records, `page` will get called again. // If there are no more records, `done` will get called. fetchNextPage(); , function done(err) if (err) console.error(err); return; ); node.js
