Javascript medium-editor markdown append image and update content

<div class="editable" contenteditable="true"></div>
<textarea name="markdown" class="markdown" /></textarea>//display none

new MediumEditor('.editable', {
    extensions: {
        markdown: new MeMarkdown(function (md) {
            document.querySelector(".markdown").textContent = md;
        }),
        img: new imgButton()
    }


$('.editable').append("<img src='abc' />");

I have a div use medium-editor & medium-editor markdown

when user type inside of .editable, textarea will sync.

I also have a button click, it will append an image into .editable

my problem is markdown only update when .editable keypress

so if I append text, textarea wont sync, unless I press any key inside of .editable again

anyone know how to tell markdown to update after append image

Solution

  • try this

    function updateTextArea(index,editable){
    var textarea = editable.parentNode.querySelector('textarea[medium-editor-textarea-id="' + editable.getAttribute('medium-editor-textarea-id') + '"]');
    if (textarea) {
        textarea.value = editable.innerHTML.trim();
    }
}

$('.editable').append("<img src='abc' />");
$('.editable').each(updateTextArea);

    The updateTextArea function will update a text area corresponds to editable area.

    Here is the code I tried

    var editor = new MediumEditor('.editable', {
            buttonLabels: 'fontawesome'
        });
           function updateTextArea(index,editable){
                var textarea = editable.parentNode.querySelector('textarea[medium-editor-textarea-id="' + editable.getAttribute('medium-editor-textarea-id') + '"]');
                if (textarea) {
                    textarea.value = editable.innerHTML.trim();
                }
            }
    $("#addImage").click(function(){
      $('.editable').append("<img src='abc' />");
      $('.editable').each(updateTextArea);
     });
$('.editable').change(updateTextArea);
