The following sample demonstrates how to get the Rich Text Editor value in button click.
Render the Rich Text Editor in form.
<form id="myForm" class="form-vertical">
<div class="form-group">
<textarea id="defaultRTE" name="defaultRTE" required maxlength="100" minlength="20" data-msg-containerid="dateError"> </textarea>
<div id="dateError" style="padding-top: 10px"></div>
</div>
<div style="text-align: center">
<button id="validateSubmit" class="samplebtn e-control e-btn" type="submit" data-ripple="true">Submit</button>
<button id="resetbtn" class="samplebtn e-control e-btn" type="reset" data-ripple="true">Reset</button>
</div>
</form>Upon submitting the form, the getValue method will be triggered. Through the FormData class, get the Rich Text Editor value.
ej.base.enableRipple(true);
ej.richtexteditor.RichTextEditor.Inject(ej.richtexteditor.Toolbar, ej.richtexteditor.Link, ej.richtexteditor.Image, ej.richtexteditor.HtmlEditor, ej.richtexteditor.Count, ej.richtexteditor.QuickToolbar);
var defaultRTE = new ej.richtexteditor.RichTextEditor({ showCharCount: true, maxLength: 100, placeholder: 'Type something' });
defaultRTE.appendTo('#defaultRTE');
var formObject = new ej.inputs.FormValidator('#form-element');
document.getElementById('validateSubmit').onclick = function () {
getValue();
};
function getValue() {
var form = document.getElementById('form-element');
var formData = new FormData(form);
var rteValue = formData.get('defaultRTE');
alert(rteValue); //Store the value to the data base.
