How can I render child row to present markdown?

koppanm

Hi, I have been using DataTables and Editor more and more extensively. Recently I have installed a Table where I need to show large text data using markdown. The child row functions properly. However, I am unable to format it to render data for markdown. I have read all available sources, but I can not compile a proper script. Please, help!
Many thanks!

Hi Miklos,

Two options:

1. Render it as HTML on the server-side through a Markdown library and a get formatter (assuming you are using the Editor PHP, .NET or Node.js libraries).
2. Do it on the client-side with a library such as this one. You would do that wherever it is that you are creating the child rows.

If you are able to link to an example, I should be able to give a more specific answer.

Many thanks Allan for your quick reply! I will give it a try and report back.
I love DataTables and Editor, although I am an absolutely amateur, so it will not be easy for you to guide me through..

Dear Allan,
Had no time to accomplish so far, just to read the info you have sent. Many thanks.
Below is my code, maybe this clarifies my trouble. I truly appreciate your help.

/*
 * Editor client script for DB table opdescript
 * Created by http://editor.datatables.net/generator
 */


addEventListener("DOMContentLoaded", function () {
    var editor = new DataTable.Editor( {
        ajax: 'php/table.opdescript.php',
        table: '#opdescript',
        fields: [
            {
                "label": "created_at:",
                "name": "created_at",
                "type": "datetime",
                "format": "YYYY-MM-DD"
            },
            {
                "label": "tags:",
                "name": "tags"
            },
            {
                "label": "content:",
                "name": "content",
                "type": "textarea",
                "attr": {
        "placeholder": 'Please enter a description here'
    }
            }
        ]
    } );




// Formatting function for row details - modify as you need
function format(d) {
     //`d` is the original data object for the row
    return (
        '<dl>' +
        '<dt><b>Leírás:</b></dt>' +
        '<dd>' +
        d.content +
        '</dd>' 
        +
        '</dl>'
    );
}



    var table = new DataTable('#opdescript', {
        ajax: 'php/table.opdescript.php',
        order: [ 1, 'desc' ],
        columns: [
        {
            className: 'dt-control',
            orderable: false,
            data: null,
            defaultContent: ''
        },
        { data: 'created_at' },
        { data: 'tags' }

    ],
        // columns: [
            // {

            //},
            //{
                //"data": "content"
            //}
        //],
        
        layout: {
            topStart: {
                buttons: [
                    { extend: 'create', editor: editor },
                    { extend: 'edit', editor: editor },
                    { extend: 'remove', editor: editor }
                ]
            }
        },
        language: {
        url: '//cdn.datatables.net/plug-ins/2.3.1/i18n/hu.json',
        },
        select: true,

    });

    // Add event listener for opening and closing details
$('#opdescript tbody').on('click', 'td.dt-control', function () {
    var tr = $(this).closest('tr');
    var row = table.row(tr);
 
    if (row.child.isShown()) {
        // This row is already open - close it
        row.child.hide();
    }
    else {
        // Open this row
        row.child(format(row.data())).show();
    }
});




});

Awesome - thank you. I would suggest that line 43 in the above is where you could do the Markdown formatting - something like:

markdown(d.content) +

where markdown() is a function from an external library. I've used markdown-it before and found it to be very effective.

Many thanks, I go ahead and give it a try. You are providing an awesome support, thanks. TwoThumbsUp!

OK, now the child row is frozen. Table loads, but that is it.

Dear Allan, after reading a lot, I am getting a little bit closer. Which default JS file have you used from the the package author (jsdelivr.com)?

Dear Allan, I have solved it.
I have found the solution here:
https://stackoverflow.com/questions/1867669/markdown-live-preview-in-textarea

It is now working perfect.
Thank you for your suggestion, it pushed me forward to achieve what I needed.
I love the Editor and Datatables. Many thanks, Miklos
