At.js Integration

RichTextEditor can easily be integrated with At.js library. To display the autocomplete list, type ‘@’.

Include At.JS style.

 <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/at.js/1.4.0/css/jquery.atwho.min.css">

Include At.JS javascript.

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/at.js/1.4.0/js/jquery.atwho.min.js"></script>

Define the At.js configuration

In below configuration, email id of employees list - email id of employees from the data source.

var config = {
    at: "@",
    data: [email id of employees list],
    displayTpl: '<li>${name} <small>${email}</small></li>',
    limit: 200
  }

Populate the employee’s email id from local or remote data and set the result to the data of At.js configuration.

        data: employeeList,
        displayTpl: '<li>${name} <small>${email}</small></li>',
        limit: 200
    };
    function created(args) {
        var textArea = this.contentModule.getEditPanel();
        $(textArea).atwho(config);
        $(textArea).on('keydown', function (e) {
            if (e.keyCode == 13 && $(textArea).atwho('isSelecting'))
                return false;
        });
    }

tagHelper
<ejs-richtexteditor id="default" actionComplete="actionComplete" value="@ViewBag.value">
    <e-richtexteditor-toolbarsettings items="@ViewBag.items"></e-richtexteditor-toolbarsettings>
</ejs-richtexteditor>
<script async src="https://cdn.embedly.com/widgets/platform.js" charset="UTF-8"></script>
<script>
  function actionComplete(args) {
        if(args.requestType === 'Links') {
            if (args.elements[0].parentNode && args.elements[0].parentNode.tagName === 'A') {
                var emberEle = document.createElement('blockquote');
                emberEle.setAttribute('class', 'embedly-card');
                emberEle.appendChild(args.elements[0].parentElement);
                emberEle.appendChild(document.createElement('p'));
                args.range.insertNode(emberEle);
            }
        }
    }
</script>
