使用 JQuery 的 nicEditor 和 onchange 事件

Question

I have used More than 5 nicEditors in my application.Below is my code

$(document).ready(function() {
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('single_answer_description')
            )
        );
    });
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('multiple_answer_description')
            )
        );
    });
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('drag_words_paragraph')

            )
        );
    });
    bkLib.onDomLoaded(function(){
        var myInstance = new nicEditor().panelInstance('drag_words_paragraph');
        myInstance.addEvent('blur', function() {
            alert("m");
        });
    });
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('drop_words_paragraph')
            )
        );
    });

});

In that I want to add onchange event with drag_words_paragraph textarea.onchange of text it will add in one div..I tried like this

bkLib.onDomLoaded(function(){
    var myInstance = new nicEditor().panelInstance('drag_words_paragraph');
    myInstance.addEvent('blur', function() {
    // Your code here that is called whenever the user blurs (stops editing) the nicedit instance
    });
});

But I can't get exact result instead im getting error removeInstance() is not a function.Please anyone help me.I am struggling for this errorlongtime.Thanks in advance

Answer 1

In your code you are declare new PaneInstance for same ID more than once.

try changing your code as below

//declare a global variable to store the editor text
var drag_words_paragraph;

$(document).ready(function() {
    // assign the text to variable
    window.drag_words_paragraph = $('#drag_words_paragraph').text();    

    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('single_answer_description')
            )
        );
    });
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            new nicEditor().panelInstance(
                document.getElementById('multiple_answer_description')
            )
        );
    });
    bkLib.onDomLoaded(function() {
        nicEditors.editors.push(
            var myInstance = new nicEditor().panelInstance('drag_words_paragraph');
             myInstance.addEvent('blur', function() {
                  debugger;
                  var text = this.instanceById('drag_words_paragraph').getContent();
                  if (window.drag_words_paragraph == text) {
                    //Text has not been changed
                    return false;
                  } else {
                    //Text has been changed
                    //You can call your functions here.
                    alert('text changed');

                    window.drag_words_paragraph = text;
                  }
                });
            )
        );
    });

Your code seems to be working.

As commented by Richard Welsh in this http://wiki.nicedit.com/w/page/518/Editor%20Events

Check the snippet below based on his workaround.

 $(function() { $('#drag_words_paragraph_text').text($('#drag_words_paragraph').text()); var myInstance = new nicEditor({ iconsPath: 'https://cdn.jsdelivr.net/nicedit/0.9r24/nicEditorIcons.gif' }).panelInstance('drag_words_paragraph'); myInstance.addEvent('blur', function() { debugger; var hiddenElem = $('#drag_words_paragraph_text'); var text = this.instanceById('drag_words_paragraph').getContent(); if ($(hiddenElem).text() == text ) { return false; } else { alert('text changed'); $(hiddenElem).text(text); } }); }); function changeText(){ var newText = $('#change_text').val(); nicEditors.findEditor('drag_words_paragraph').setContent(newText); }

 body { min-height: 500px; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdn.jsdelivr.net/nicedit/0.9r24/nicEdit.js"></script> <textarea class="form-control" style="width: 300px; height: 100px;" name="drag_words_paragraph" id="drag_words_paragraph"> Some random text </textarea> <div style="display:none" id="drag_words_paragraph_text"></div> <br/> <textarea id="change_text" placeholder="enter some text here" ></textarea> <button id="change_text_btn" onclick="changeText();">change text</button>

Try this:

document.querySelector('.nicEdit-main').addEventListener("input", function(e) {
   console.log(e.target.innerHTML)
}, false);
